A History of Measles Outbreaks in United States

We have come a long way since the development of the first measles vaccines in the early 1960s…

Pre-Vaccine Era Measles Outbreaks

Unvaccinated children exposed to measles are quarantined for at least 21 days.
Unvaccinated children exposed to measles are quarantined for at least 21 days.

In the pre-vaccine era, measles was a very common childhood disease.

As it is now, it was also a deadly disease.

In the 1950s, there were 5,487,332 cases (just under 550,000 a year) and 4,950 deaths (about 500 each year).

In 1962, there were 469,924 cases of measles in the United States and 432 deaths.

Post-Vaccine Era Measles Outbreaks

The first measles vaccines were licensed between 1963 and 1965, but it was the first national measles eradication campaign in 1966 that got people vaccinated and measles rates down.

In 1970, there were only 47,351 cases and 89 deaths.

Rates continued to drop until the large outbreaks between 1989 to 1991, when there were 55,622 cases and 123 deaths. The addition of a measles booster shot got measles outbreaks under control again. By 2000, when measles was declared eliminated in the United States, there were just 86 cases and one death.

Post-Elimination Era Measles Outbreaks

Measles cases usually begin increasing in April and May. How many cases will we see this year?

Declaring measles eliminated in the United States didn’t mean that we didn’t have any more measles, after all, it hasn’t been eradicated yet. It just that we are no longer seeing the endemic spread of measles. Since 2000, all of the latest measles outbreaks have been imported from outside the country, or at least they are started by cases that are imported.

We have seen more than a few records in the post-elimination era, including:

  • the year with the historic low number of measles cases – 37 cases in 2004
  • the year with the largest number of cases since 1994 – 667 cases in 2014
  • the largest single outbreak since the endemic spread of measles was eliminated – 377 cases in Ohio in 2014

In 2015, we got a reminder of how deadly measles can be. Although there have been other measles deaths and SSPE deaths in the past ten years, unlike the 2015 death, they are usually buried in CDC reports and aren’t published in the newspaper.

2017 Measles Outbreaks

The first new case of 2017 was an unvaccinated adult in San Luis Obispo County, California who was exposed to international travelers over the holidays. The person exposed others to measles at the Twin Cities Community Hospital emergency department in Templeton while contagious in early January.

The second case of 2017 was related to an LA county outbreak that started at the end of 2016 – a resident of Ventura County.

And it went on, with other measles cases in 2017 including:

  • at least 122 cases
  • cases in 16 states, including California, Florida, Kansas, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nebraska, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Utah, and Washington
  • an infant in San Luis Obispo County that was too young to be vaccinated and who had contact with an unvaccinated adult with measles
  • one new case in the Los Angeles County outbreak, which is now up to 20 confirmed measles cases (including 18 in LA County), all unvaccinated
  • four new cases in Ventura County, California that are linked to another Ventura County measles case and the LA County outbreak, which is now up to 24 cases
  • a case in Jersey City, New Jersey following international travel who exposed people at multiple places, including a hospital, pharmacy, mall, and on a commuter train
  • an infant in Suffolk County, New York who had been overseas
  • an unvaccinated 7-month-old baby from Passaic County, New Jersey who had been traveling out of the country and may have exposed others at area hospitals (a good reminder that infants who are at least 6 months old should get an MMR vaccine before leaving the country)
  • two cases in Salt Lake County, Utah – which began in a resident who had “received all appropriate vaccinations” and developed measles after traveling outside the US and then spread to another person “who had contact with the first case.” According to the SLCoHD, “One of the two individuals with measles had received one MMR vaccine.”
  • two cases in King County, Washington – a man and his 6-month-old infant, both unvaccinated, developed measles after traveling to Asia, and exposed many others around Seattle, including at a Whole Foods, a sandwich shop, their apartment building, and two Amazon buildings.
  • a confirmed case in Omaha, Nebraska, who exposed people on a Delta flight and multiple places in Douglas and Sarpy counties, including the Bergan Mercy Hospital Emergency Room.
  • a young child in Macomb Count, Michigan who required hospitalized and has been linked to international travel
  • a suspected case at William Allen White Elementary School in Lyon County, Kansas which has led to the quarantine of unvaccinated students for 3 weeks
  • an unvaccinated student at Laguna Beach High in Orange County, California, which led to the quarantine of at least 6 unvaccinated students
  • a staff member at Discovery Academy of Lake Alfred in Florida
  • an unconfirmed case in an infant who attended the College of Staten Island Children’s Center in New York
  • two children in Minnesota without a known source of infection
  • another child in Minnesota – among the three Somali Minnesotans in this outbreak are two children who are just two years old – all of the cases were unvaccinated and two required hospitalization, although the common source is still not known. Vaccine hesitancy has been a problem among the Somali Minnesotans because of Wakefield‘s MMR study.
  • five more unvaccinated children in Minnesota, as the outbreak grows to 8.
  • a confirmed case in North Platte, Nebraska who may have exposed others at a middle school, church youth group, the Great Plains Health Emergency Room, a medical office, and a lab.
  • a resident of Livingston County, Michigan who exposed others at area restaurants and St. Joseph Mercy Brighton Hospital after getting measles on a plane ride with an unvaccinated child
  • another case in Minnesota, bringing the outbreak count to 9 unvaccinated children.
  • three more cases in Minnesota, bringing this outbreak case count to 12, with at least 200 people in quarantine.
  • four possible cases in Nebraska
  • eight more cases in Minnesota, bringing this outbreak case count to 20 young children under age 5 years, and now including an infant under age 12 months.
  • four more cases in Minnesota, bringing this outbreak case count to 24 young children under age 5 years and surpassing the size of the 2011 measles outbreak in the Somali community in the same area, which was also mostly among intentionally unvaccinated children.
  • five more cases in Minnesota, including the first outside of Hennepin County – spreading to nearby Stearns County, bringing this outbreak case count to 29 young children under age 5 years, with only one that was vaccinated.
  • three more cases in Minnesota, as the outbreak spreads to the third county – Ramsey County.
  • more measles (2 new cases) in Minnesota (Hennepin County, Ramsey County, Crow Wing County, and now Le Sueur County), where the ongoing outbreak is up to 66 cases, almost all unvaccinated children and where there has been a call to accelerate the two dose MMR schedule for kids over age 12 months.
  • a teen visiting the United States from India who developed measles and exposed others at a hotel and a hospital in Bergen County, New Jersey and in upstate New York.
  • a child in Maryland who was admitted to Children’s National Medical Center in Washington, D.C.
  • more measles (3 new cases) in Minnesota (Hennepin County, Ramsey County, Crow Wing County, and Le Sueur County), where the ongoing outbreak that has been confirmed to be from the wild type B3 strain is up to 68 cases, almost all unvaccinated children.
  • a case in Pennsylvania who exposed others at a visitor center
  • someone who visited the MIT Museum in Cambridge, Massachusetts.
  • two new cases in Minnesota, ending speculation that the outbreak, now up to 70 cases, was over…
  • one new case in Minnesota, raising the number of cases in this ongoing outbreak to 78 cases.
  • a healthcare worker in New York who is employed by Hudson Headwaters Health Network and also works at a Warren County medical practice.
  • someone in Franklin County, Maine (their first case in Maine in 20 years!) who traveled out of the country and caught measles, returning home and possibly exposing others at a movie theater, restaurant, farmers market, and hospital.
  • A case in Butler County, Kansas. Many remember that one of the largest outbreaks of 2014 was in Kansas.
  • an unvaccinated man who lives in Hennepin County, raising the number of cases in this ongoing outbreak (an outbreak that has already cost over $500,000 to contain and which many hoped would soon be over) that started in March to at least 79 cases. With the new case, the clock starts ticking again and Minnesota will have to wait to see if new cases appear over the next 3 weeks.
  • passengers from 13 states on an American Airlines flight from New York to Chicago were exposed to a person with measles in early July, including a 12-week-old infant who required preventative treatment with immune globulin (IG), as she was too young to be vaccinated.
  • a fully vaccinated resident of Onondaga County, New York who was exposed on a domestic flight, only developed mild symptoms, but did expose others.
  • someone who exposed others at the Penn State University Hetzel Union Building Bookstore and other places in State College, Pennsylvania.
  • a second case in the Wichita, Kansas area, this time in Sedgwick County, with exposures at a church, dental office, elementary school, and multiple stores over at least 3 days.
  • a possible case in Sedgwick County, Kansas, a child too young to be vaccinated who may have been exposed at a church. Three other exposed infants who were too young to be vaccinated and who were considered at risk to get measles in this outbreak received immunoglobulin treatment.
  • a traveler who spent time in Hampton Beach in New Hampshire, exposing others.
  • a 46-year-old male in Ohio that got the disease while traveling internationally.

2017 would have been a mild year for measles, except for the really big outbreak in Minnesota… 79 people got measles, 71 were unvaccinated, more than 500 people were quarantines, and the outbreak cost over $1.3 million to contain.

2016 Measles Outbreaks

Starting slow, 2016 ended as a fairly average year for measles:

  • 83 cases
  • cases in 17 states, including Alabama, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Illinois, Massachusetts, Michigan, Minnesota, New York, North Carolina, Oregon, Tennessee, Texas, and Utah
  • a large outbreak in Arizona, 23 cases, linked to a private detention center
  • a large outbreak in Shelby County, Tennessee, at least seven cases, including six unvaccinated and one partially vaccinated child
  • an ongoing measles outbreak in Los Angeles County and Santa Barbara County that has been linked to the Los Angeles Orthodox Jewish community
  • a case in Colorado in which an unvaccinated adult traveled internationally and ended up exposing many people “from Dec. 21 to 29, 2016, who was at a wide variety of locations in the Denver-Boulder area,” including an Urgent Care center and the Parker Adventist Hospital Emergency Department

As in other years, many of these outbreaks involved unvaccinated children and adults. One case involved a child at the Yuba River Charter School in California, a Waldorf School with very high rates of unvaccinated children.

2015 Measles Outbreaks

With a large outbreak in California, 2015 got off to a very strong start.

Most concerning, more and more, cases don’t seem to have an source that is easy to find, which could mean that the endemic spread of measles has returned in the United States. So instead of having to travel out of the country or be exposed to someone who got measles with a link to international travel, you could get measles just by going to a ball game, a movie theater, or to Disneyland. That makes it more important than ever to learn how to avoid measles.

Among the 189 measles cases and outbreaks in 2015 were:

  • 113 cases that were associated with a multi-state outbreak that was linked to Disneyland in California. Before it was declared over on April 17, a few unvaccinated travelers also help spread measles from this outbreak to large outbreak in Quebec, Canada. All in all, the outbreak was linked to at least 113 cases in California and an additional 169 cases in Arizona (5), Nebraska (1), Utah (3), Colorado (1), Washington (2), Oregon (1), Mexico (1), and Canada (155).
  • 13 cases, including an adult worker and 12 infants too young to be vaccinated at the KinderCare Learning Center in Illinois.
  • At least 13 cases, all intentionally unvaccinated, in a South Dakota outbreak that started with an unvaccinated adult traveling to India.
  • Five cases in Clallam County, Washington, including four who were not vaccinated, which cost at least $36,000 to contain and led to the death of an immunosuppressed woman.

In addition to these large outbreaks, 2015 also saw a number of quarantines for unvaccinated students, closing of daycare centers, and a recommendation from a California Department of Health state epidemiologist that people who are not vaccinated against measles “avoid visiting Disney” and “crowded places with a high concentration of international travelers, such as airports.”

Other measles cases in 2015 include:

  • A student at UC Berkeley who may have exposed others to measles on a public bus.
  • A confirmed case in Fairbanks, Alaska – their first case in 15 years, who flew in from Seattle (and is probably the King County case discussed below) and may have exposed others at an area Walmart, Home Depot, Walgreens, several supermarkets, the airport, and hospital, etc.
  • A confirmed case in King County, Washington, who may have exposed others in Seattle, including at an area McDonalds, the Baroness Hotel, a drug store, and the Sea-Tac Airport.
  • A confirmed case in Branson, Missouri, a traveler from Asia, who was contagious when visiting the ER, three local businesses, and perhaps his flight to town.
  • A confirmed case in the Washington D.C. area.
  • Another case of measles in Spokane County, Washington – an unvaccinated person that was exposed to the other case in the area.
  • An unvaccinated student from Europe in Boston, Massachusetts who also traveled to Maine and New Hampshire.
  • Another unvaccinated child in St. Lucie County, Florida – bringing the total to five cases in central Florida in what so far looks like two separate outbreaks.
  • Another case in Indian River County, Florida – an unvaccinated child.
  • An unvaccinated adult in Spokane, Washington – the first case in the area since 1994.
  • Two unvaccinated adults in Indian River County, Florida, one of whom contracted measles while traveling out of the country.
  • An unvaccinated 6-year-old in St. Lucie County, Florida who attended Fairlawn Elementary School in Fort Pierce – leading to five unvaccinated students being kept out of school until early May.
  • The first case in Oklahoma since 1997, a case in Stillwater.
  • A case in Florida, a traveler who was contagious while attending a conference at the Gaylord Palms Resort and Convention Center and also in Maimi-Dade, Orange, and Sarasota counties.
  • A new case in Illinois, the 15th – and so far not linked to the other two outbreaks in the state.
  • A student at Princeton University in New Jersey.
  • Another case of measles in the Washington D.C. area, a case without a known source.
  • A case in a student at Elgin Community College in Kane County, Illinois.
  • A hospitalized infant in Atlanta, Georgia.
  • An unvaccinated 1 year old in Jersey City, New Jersey.
  • A traveler in King County, Washington that may have exposed others in Seattle. The unvaccinated visitor is from Brazil, where there was a large outbreak of measles last year (almost 400 cases).
  • At least one more case in Clark County, Nevada and four more possible cases in Southern and Northern Nevada, which led to the quarantine of at least 11 students at the Spanish Springs Elementary School.
  • A case in Franklin County, Pennsylvania.
  • Four cases of measles in travelers, including two international travelers, who visited Florida.
  • A case in Washington D.C.
  • A student at Bard College in Dutchess County, New York, who exposed many people while traveling on an Amtrak train to Penn Station in New York City.
  • An unvaccinated woman in New Castle County, Delaware who had recently traveled out of the country.
  • A case on the University of Minnesota Twin Cities campus in a student that had recently returned from out of the country. Although others were exposed, it is considered to be a “highly immunized” population, so hopefully the outbreak won’t spread.
  • Two more cases in Arizona that are tied to the Disneyland outbreak, including a woman in Phoenix who may have exposed others up to 195 children at the Phoenix Children’s East Valley Center, including a 3-year-old getting chemotherapy for leukemia.
  • An adult in Cook County, Illinois which in not linked to Disneyland.
  • A student at Valley High School in Las Vegas which led to the quarantine of 36 unvaccinated students until early February.
  • Four cases among an unvaccinated family in Kearny, Arizona that is directly linked to the Disneyland outbreak.
  • A child in Sioux Falls, South Dakota that is unrelated to 13 recent cases in the area and which has no link to travel out of the area.
  • A new case in Oakland County, Michigan that is likely linked to the Disneyland measles outbreak, meaning that the outbreak has now spread to include 7 states and 2 countries.
  • A case in Maricopa County, Arizona has been linked to the Disneyland outbreak.
  • A person in Nebraska who could have exposed others in Omaha and Blair, including at the Omaha Children’s Museum.
  • A case in Lane County, Oregon that has been linked to the Disneyland measles outbreak.
  • A resident of Tarrant County in North Texas who developed measles after a trip to India.
  • Another unvaccinated person in Utah with links to the Disneyland outbreak has tested positive for measles, bringing the total in that state to 3 cases.

In addition to the 36 measles cases that have been associated with the Disneyland outbreak, California already has 5 additional measles cases this year with no link to Disney, including cases in Alameda, Orange, and Ventura Counties.

Meningitis Vaccines

Meningitis is classically defined as an inflammation of the membranes that cover the brain and spinal cord.

Infections that can cause meningitis include:

  • viruses – also called aseptic meningitis, it can be caused by enteroviruses, measles, mumps, and herpes, etc.
  • bacteria – Streptococcus pneumoniae, Neisseria meningitidis, Listeria monocytogenes, Haemophilus influenzae type b (Hib), Group B strep
  • a fungus – Cryptococcus, Histoplasma
  • parasites – uncommon
  • amebas – Naegleria fowleri

There are even non-infectious causes of meningitis, including the side-effects of medications and certain systemic illnesses.

Meningitis Vaccines

Teens and young adults need two different kinds of meningococcal vaccines to get full protection.
Teens and young adults need two different kinds of meningococcal vaccines to get full protection.

Fortunately, many of these diseases that cause meningitis are vaccine-preventable.

You don’t often think about them in this way, but all of the following vaccines are available to prevent meningitis, including:

  • Hib – the Haemophilus influenzae type b bacteria was a common cause of meningitis in the pre-vaccine era, in addition to causing epiglottitis and pneumonia
  • Prevnar – you mean it’s not just an ear infection vaccine?
  • MMR – both measles and mumps can cause meningitis
  • Menactra and Menveo – serogroup A, C, W, Y meningococcal vaccines
  • Bexsero and Trumenba – serogroup B meningococcal vaccines

But just because your child has been vaccinated doesn’t mean that you are in the clear if they are exposed to someone with meningitis. They might still need preventative antibiotics if they are exposed to someone with Hib or meningococcal meningitis.

Still, getting fully vaccinated on time is the best way to prevent many of these types of meningitis and other life-threatening diseases.

What to Do If Your Child Is Exposed to Meningitis

Meningitis is classically defined as an inflammation of the membranes that cover the brain and spinal cord, and it can be caused by:

  • viruses – also called aseptic meningitis, it can be caused by enteroviruses, measles, mumps, and herpes, etc.
  • bacteria – Streptococcus pneumoniae, Neisseria meningitidis, Listeria monocytogenes, Haemophilus influenzae type b (Hib), Group B strep
  • a fungus – Cryptococcus, Histoplasma
  • parasites – uncommon
  • amebas – Naegleria fowleri

Surprisingly, there are even non-infectious causes of meningitis. These might be include side-effects of a medication or that the child’s meningitis is a part of another systemic illness.

What to Do If Your Child Is Exposed to Meningitis

While meningitis can be contagious, it greatly depends on the type of meningitis to which they are exposed as to whether or not your child is at any risk.

Teens and young adults need two different kinds of meningococcal vaccines to get full protection.
Teens and young adults need two different kinds of meningococcal vaccines to get full protection.

So while the general advice is to “tell your doctor if you think you have been exposed to someone with meningitis,” you should try and gather as much information as you can about the exposure.

This information will hopefully include the type of meningitis they were exposed to, specifically if it was bacterial or viral, the exact organism if it has been identified, and how close of an exposure it was – were they simply in the same school or actually sitting next to each other in the same room.

For example, while the CDC states that “people who are close contacts of a person with meningococcal or Haemophilus influenzae type b (Hib) meningitis are at increased risk of getting infected and may need preventive antibiotics,” they also state that “close contacts of a person with meningitis caused by other bacteria, such as Streptococcus pneumoniae, do not need antibiotics.”

And you often don’t need to take any preventive measures if you are exposed to someone with viral meningitis.

While that might sound scary, it is basically because you typically aren’t at big risk after this kind of exposure. You could get the same virus, but the chances that it would spread and also cause meningitis are very unlikely.

Not only does Viera Scheibner think that vaccines cause SIDS and shaken baby syndrome, she thinks they are contaminated with amoeba.
The Naegleria fowleri ameba that can cause meningitis can be found in warm freshwater, including lakes and rivers.

Other types of meningitis, like primary amebic meningoencephalitis (PAM) and fungal and parasitic meningitis aren’t even contagious.

The Histoplasma fungus spreads from bird or bat droppings, for example, not from one person to another.

And parasites typically spread from ingesting raw or undercooked food, or in the case of Baylisascaris procyonis, from ingesting something contaminated with infectious parasite eggs in raccoon feces.

What to Do If Your Unvaccinated Child Is Exposed to Meningitis

Vaccines can prevent a number of different types of meningitis.

From Hib and Prevnar to MMR and the meningococcal vaccines, our children routinely get several vaccines to prevent meningitis.

While these meningitis vaccines don’t protect us from all of the different types of viruses, bacteria, and other organisms that can cause meningitis, they do prevent many of the most common.

So what do you do if your unvaccinated child is exposed to meningitis?

You should immediately call your pediatrician or local healthy department, because they might need:

  • antibiotics (usually rifampin, ciprofloxacin, or ceftriaxone) if the meningitis was caused by Neisseria meningitidis
  • antibiotics (rifampin) if the meningitis was caused by Haemophilus influenzae type b (Hib)

The availability of these antibiotics isn’t a good reason to skip or delay getting vaccinated though, as you won’t always know when your kids have been exposed to meningitis and not all types of vaccine-preventable meningitis can be prevented with antibiotics.

Of course, getting fully vaccinated on time is the best way to prevent many of these types of meningitis and other life-threatening diseases.

What to Do If Your Vaccinated Child Is Exposed to Meningitis

Even if your child is vaccinated, they might still need preventative antibiotics if they are exposed to someone with Hib or meningococcal meningitis, as vaccines are not 100% effective.

“Regardless of immunization status, close contacts of all people with invasive meningococcal disease , whether endemic or in an outbreak situation, are at high risk of infection and should receive chemoprophylaxis.”

AAP Red Book on Meningococcal Infections

This is especially true if they are not fully vaccinated.

Remember, to be fully vaccinated against Haemophilus influenzae type b, kids get a 2 or 3 dose primary series of the Hib vaccine when they are infants and a booster dose once they are 12 months old.

In the case of exposure to Hib meningitis, antibiotic prophylaxis would be recommended if:

  • the child is fully vaccinated, but there is a young child, under age 4 years, in the house who is unvaccinated or only partially vaccinated
  • the child is fully vaccinated, but there is another child in the house who is immunocompromised
  • the child is only partially vaccinated and under age 4 years
  • there is an outbreak in a preschool or daycare, with 2 or more cases within 60 days

And anyone exposed to someone with meningococcal meningitis should likely get antibiotics (chemoprophylaxis), even if they are fully vaccinated.

Talk to your pediatrician or local health department if your child is exposed to meningitis and you aren’t sure what to do, whether or not your child has been vaccinated.

What to Know About Getting Exposed to Meningitis

Learn what to do if your child is exposed to someone with meningitis, especially if they are unvaccinated, or have been exposed to someone with Hib meningitis or meningococcal disease.

Your Baby’s First Vaccines

Your baby’s first vaccines are very important.

While they don’t provide instant protection, they do start your baby on the path to eventually getting protected from 16 different vaccine-preventable diseases.

Your Baby’s First Vaccines

Rotavirus vaccines are associated with a very small risk of intussusception, but that is not a good reason to miss the benefits of this vaccine.

After the birth dose of the hepatitis B vaccine, your baby’s first vaccines when you visit your pediatrician for their two month check up will include:

  • DTaP – diptheria – tetanus – pertussis
  • IPV – polio
  • Hepatitis B
  • Hib – haemophilus influenzae type b
  • Prevnar 13 – pneumococcal disease
  • Rotavirus

Sound like too many? Those vaccines work to protect your baby against eight vaccine-preventable diseases!

And it doesn’t mean that your baby has to get six shots.

The rotavirus vaccine is oral – your baby drinks it.

And many of the other vaccines can be given as a combination vaccine, either Pediarix (combines DTaP-IPV-HepB) or Pentacel (combines DTaP-IPV-Hib), to reduce the number of individual shots your baby needs to get even more.

While that still means multiple injections, there are things you can do to minimize the pain during and after the vaccines, from breastfeeding and holding your baby to simply trying to get them distracted.

Your Baby’s Next Vaccines

After their first vaccines at two months, your baby will complete their primary series of vaccines with repeated dosages of the same vaccines at four and six months.

Why do we need to repeat the same vaccines?

Because that’s often what it takes to help us build up an immune response to a vaccine, especially at this age.

These first vaccines prime the immune system, which when followed by a later booster vaccine, provide good protection against each disease.

start your baby on the path to eventually getting protected from 16 different vaccine-preventable diseases.
Ari Brown, MD explains why you shouldn’t delay or skip your child’s vaccines.

And the requirement of multiple dosages of a vaccine is a small price to pay to be able to skip the symptoms and risk of more serious consequences that come from getting a natural infection and natural immunity.

Did your baby have a reaction to their first set of vaccines?

While some fever, pain, and fussiness is not unexpected, be sure to tell your health care provider if your baby had a reaction that you think was more severe, like a high fever or non-stop crying for several hours.

Can you expect a reaction to your baby’s second set of shots if they had a reaction to the first? Probably not. Side effects, even those that are serious, rarely happen again, even when the same vaccines are given.

Your Baby’s Vaccines

While you certainly shouldn’t skip or delay any of these vaccines, you should know that:

  • the routine age for starting these vaccines is at two months, but
  • if necessary, they can be given as early as when a baby is six weeks old.
  • the routine interval between dosages of the primary series of these vaccines is two months, but
  • if necessary (usually as part of a catch-up schedule), these vaccines can be usually be given as soon as four weeks apart, although the third dose in the series of DTaP, IPV, and Hepatitis B vaccines shouldn’t be given any sooner than at age six months.
  • infants who will be traveling out of the United States should get an early MMR vaccine – as early as six months of age

And if your baby is at least six months old during flu season, then they will also need two doses of the flu shot given one month apart. The minimum age to get a flu shot is six months, and kids get two doses during their first year of getting vaccinated against the flu to help the vaccine work better.

Learn more about if you are on the fence. Your baby needs to be vaccinated and protected.

Quarantine Signs for Vaccine-Preventable Diseases

If everyone breezed through vaccine-preventable diseases so easily back in the pre-vaccine era, then why were so many folks held under quarantine?

Quarantine Sign

Vaccine-preventable diseases have always been known to be dangerous and life-threatening.

If they were once thought of as a way of life, it was only because there was no way to avoid them!

As someone with an uncle who developed severe paralytic polio disease a few years before the first vaccine was developed, I can tell you that these diseases were no walk in the park.

Still, while quarantines are helpful to control disease outbreaks, they clearly aren’t enough. That’s evident by the way that vaccines were used in Leicester to control smallpox, even though some folks say it was all due to quarantines. It wasn’t.

How long would quarantine last?

Usually through at least one incubation period for the disease.

Quarantine Signs
Smallpox quarantine sign A Board of Health quarantine poster warning that the premises are contaminated by smallpox.
Diphtheria quarantine sign. Diphtheria quarantine sign.
Polio quarantine sign Polio quarantine sign.
In the pre-vaccine era, we had outbreaks of polio, and other, now vaccine-preventable diseases. Whooping cough quarantine sign.
Unvaccinated children exposed to measles are quarantined for at least 21 days. Mumps quarantine sign
Chickenpox quarantine sign Rubella quarantine sign.

Have you ever seen any of these quarantine signs?

If so, have you seen any of them lately?

That’s because vaccines work.

What to Know About Quarantine Signs for Vaccine-Preventable Diseases

In the pre-vaccine era, quarantines were the only way to try and help stop many diseases from spreading in the community.

Four Generations of Vaccines and Vaccine Preventable Diseases

This image that has been floating around the Internets conveys a lot of information, both about vaccines and vaccine-preventable diseases. And about the propaganda being pushed by the anti-vaccine movement.

Four generations of vaccines or vaccine misinformation?
Four generations of vaccines or vaccine misinformation?

A lot has changed over the last four generations…

Four Generations of Vaccine Preventable Diseases

In the United States, we have seen:

  • 1949 – the last smallpox outbreak
  • 1970s – the last outbreak of respiratory diphtheria
  • 1979 – endemic polio was declared eliminated
  • 1979 – smallpox was declared eradicated
  • 2000 – endemic measles was declared eliminated
  • 2000- neonatal tetanus was declared eliminated
  • 2004 – endemic rubella and congenital rubella syndrome were declared eliminated
  • 2009 – endemic respiratory diphtheria was declared eliminated

But there hasn’t been as much change as some folks think.

Four Generations of Vaccines

For one thing, kids don’t get 69 vaccines today as part of the recommended immunization schedule.

We don’t even have 69 vaccines available to give children today!

And while 200+ vaccines are being tested or are in the “pipeline,” very few will end up on the childhood immunization schedule. For example, many of these are therapeutic vaccines to treat cancer, allergies, and other conditions. And a lot of the other pipeline vaccines are for the same infectious disease, including 36 vaccines being tested to prevent or treat HIV and 25 to prevent the flu.

So how many vaccines do kids actually get?

Kids today routinely get 13 vaccines to protect them from 16 vaccine-preventable diseases. More than 13 vaccines are available, but some aren’t used in the United States and some are only used in special situations or for high risk kids.

Also, looking at historical immunization schedules, it is clear that folks in the 1940s and 50s didn’t get just two vaccines.

Did some kids really get annual tetanus and typhoid vaccine boosters back then?

It’s possible, after all, by the 1930s, we did have individual vaccines against diphtheria, tetanus, pertussis, typhoid, and smallpox.

This was followed by:

  • 1948 – the individual diphtheria, tetanus, and pertussis vaccines become combined in a single DTP vaccine
  • 1955 – first polio vaccine – IPV
  • 1962 – change to oral polio vaccine – OPV
  • 1963-68 – first measles vaccines
  • 1967 – first mumps vaccine
  • 1969 – first rubella vaccine
  • 1971 – the individual measles, mumps, and rubella vaccines become combined in a single MMR vaccine
  • 1972 – routine vaccination with smallpox vaccines end in the US

The next big change was the addition of the Hib vaccine to the schedule in 1985.

“…for those trained in pediatrics in the 1970s, Hib (Haemophilus influenzae type b) was a horror.”

Walter Orenstein, MD

This was followed in 1989, with the addition of the hepatitis B vaccine, expanded age ranges for Hib, and the start of the switch to DTaP.

By 2000, kids got protection against 11 vaccine-preventable diseases, and routinely got the DTaP, MMR, IPV, Hib, chicken pox, Prevnar, hepatitis B, and Td vaccines.

Over the years, vaccines and protection against rotavirus, hepatitis A, meningococcal bacteria, HPV, and a yearly flu shot were added to the schedule.

We still haven’t gotten to 69 vaccines though.

Looking at the latest immunization schedule from the CDC and AAP, it should be clear that kids don't get 69 vaccines.
Looking at the latest immunization schedule from the CDC and AAP, it should be clear that kids don’t get 69 vaccines.

Kids today do routinely get:

  • 13 vaccines, including DTaP, IPV (polio), hepatitis B, Hib, Prevnar 13, rotavirus, MMR, Varivax (chicken pox), hepatitis A, Tdap, HPV, MCV 4 (meningococcal vaccine), and influenza
  • protection against 16 vaccine-preventable diseases, including diphtheria, tetanus, pertussis, measles, mumps, rubella, polio, chicken pox, pneumococcal disease, hepatitis A, hepatitis B, meningococcal disease, HPV, rotavirus, Hib, and flu
  • about 28 doses of those vaccines by age two years
  • about 35 doses of those vaccines by age five years
  • as few as 23 individual shots by age five years if your child is getting combination vaccines, like Pediarix or Pentacel and Kinrix or Quadracel and Proquad
  • about 54 doses of those vaccines by age 18 years, with a third of that coming from yearly flu shots

How do you get a number like 69?

You can boost your count to make it look scarier by counting the DTaP, MMR, and Tdap vaccines as three separate vaccines each (even though they aren’t available as individual vaccines anymore). That quickly turns 8 shots into “24 vaccines.”

And that’s fine – as long as you are consistent. You can’t count them each as three vaccines today, but just as one when mom, grandma and great-grandma got them. If you are counting individual components of those vaccines, then great-grandma didn’t just get two vaccines, especially when you consider that she almost certainly would have gotten multiple doses of the DPT vaccine.

Paradoxically, even more antigens have been taken off the schedule with the removal of the smallpox and DPT vaccines. In 1960, kids got exposed to 3,217 different antigens from the smallpox, polio, diphtheria, tetanus and whole cell pertussis vaccines. All of today’s vaccines on the schedule expose them to just 177 different antigens!

Why does that matter? It is the antigens that are stimulating the immune system, so if you were really concerned about a number, that would be the one to look at.

More Vaccines Equal More Protection

Of course, the number of vaccines kids get and how they have increased over time is very important. But not in they way anti-vaccine folks like to think.

It is important because kids today are protected against and don’t have to worry about the consequences of many more life-threatening diseases, like bacterial meningitis (Hib and the pneumococcal bacteria), epiglottitis (Hib), liver failure and liver cancer (hepatitis B), severe dehydration (rotavirus), and cervical cancer (HPV), etc.

If you think kids get too many vaccines today, then you have no idea what things were like in the pre-vaccine era.

Polio Survivor Stories

You probably don’t know anyone who ever had polio.

The Last Case of Polio

After all, the United States has been free of polio since 1979. At least that’s when we had the last endemic case or the last case that originated here.

The last case was in 1993. At least that’s when we had the last imported case of polio in the United States.

A 2005 outbreak of vaccine derived poliovirus in 2005 among a group of unvaccinated Amish in Minnesota didn’t cause any symptoms. They had probably been exposed to someone outside the United States that was still shedding after getting an oral polio vaccine, which hadn’t been used in the United States since 2000.

And then there were these following “last cases:”

  • The last case of VAPP that was acquired in the United States – 1999.
  • The last case of VAPP that was acquired outside the United States – 2005 – an unvaccinated 22-year-old U.S. college student who became infected with polio vaccine virus while traveling in Costa Rica in a university-sponsored study-abroad program.

And then there is the final last case of VAPP – 2009 – a patient with a long-standing combined immunodeficiency who was probably infected in the late 1990s, even though she didn’t develop paralysis until years later.

Polio Survivor Stories

Since vaccines work and the United States has essentially been polio free since 1979, it wouldn’t be surprising if you don’t know anyone who ever had polio.

Or do you?

“The doctors told my parents that little could be done for me, so my father prepared for my funeral. Fortunately, I recovered, except for the use of my right hand.”

Archbishop Desmond Tutu on Vaccination’s Lifetime of Blessings

You might not have ever have even heard of anyone who had polio?

Or have you?

A few recent news stories highlight just how common polio used to be in the pre-vaccine era:

  • Mitch McConnell Wouldn’t Meet with the March of Dimes Even Though They Treated His Polio as a Child
  • Joni Mitchell – after the stuff about Morgellons, you can read about how she battled polio as a child

“When Joni turned 10 years old in late 1953, she woke up one morning paralyzed. It was quickly diagnosed and she was shipped to a polio colony in Saskatoon – similar to a leper colony designed to halt the spread of the disease.”

Do you know who else had polio?

Itzhak Perlman, a polio survivor, now works to end polio.

  • Alan Alda
  • Arthur C. Clarke
  • Francis Ford Coppola – “contracted polio and spent almost a year in bed, his legs paralyzed.”
  • Mia Farrow
  • Frida Kahlo
  • Jack Nicklaus
  • Itzhak Perlman – has needed crutches to walk since he contracted polio at age 4 years
  • David Sanborn
  • Dinah Shore
  • Donald Sutherland
  • Desmond Tutu –
  • Neil Young

Of course, in addition to all of the polio survivor stories, there are stories that aren’t told of the people who didn’t survive polio.

Except when those stories are told too…

For anyone who wants to say that polio is mild or spread other myths about polio, please be sure to read these stories.

What to Know About Polio Survivor Stories

Reading polio stories, from survivors and of those who died, helps reinforce how important it is that we eradicate this vaccine-preventable disease as soon as possible.
