Vaccine Schedules from the 1940s to 2019

To scare parents away from vaccinating and protecting their kids, anti-vaccine folks continue to push the idea the kids get too many vaccines at too early an age.

They don’t.

When did we have a vaccine schedule when we gave just two vaccines?
When did we have a vaccine schedule when we gave just two vaccines?

They try to reinforce the idea by comparing things to the “good ol’ days,” when they think kids only got one dose of one or two vaccines.

Did they?

Vaccine Schedules from the 1940s to 2019

Let’s take a look at how the vaccine schedule has evolved over time to see how many vaccines kids used to get. Looking at the old vaccine schedules can also help you understand how we got to our current schedule.

Although not a formal schedule, the first vaccine recommendations were published in the AAP’s Special Committee on Prophylactic Procedures Against Communicable Diseases 1938 pamphlet, Routine measures for the prophylaxis of communicable diseases.

It included vaccines against diphtheria, pertussis, rabies, tetanus, tuberculosis, typhoid fever, and smallpox.

That’s the schedule from 1948!

Surprised?

Many of you were led to believe that kids only got 2 vaccines back in the day. Instead, they got more vaccines and multiple doses of those vaccines.

Multiple doses with formaldehyde inactivated vaccines which contained aluminum. And thimerosal. And far more antigens than kids are exposed to today, even though they now get many more vaccines.

My uncle got polio around the time this vaccine schedule was released in 1951, but before the first polio vaccines were being routinely used.

By the early 1950s, the DPT vaccine became routine. Other vaccines were also available for special situations, including rabies, typhoid, parathyphoid, and the BCG vaccine.

And of course, we got the polio shot in 1955!

Kids got multiple doses of DPT, DT, polio, and smallpox vaccines in 1960.
Kids got multiple doses of DPT, DT, polio, and smallpox vaccines in 1960.

Although few people remember, the original polio vaccines were monovalent and only included one polio strain in each shot. So you had to get multiple shots to get protected from all three strains!

The polio shot, was used until 1962, when we switched to the oral polio vaccine. Trivalent OPV wasn’t licensed until 1963 though. Before that, kids got multiple doses of monovalent OPV, types 1, 2, and 3.

The ACIP committee came up with four different dosage schedules for measles vaccines in 1964.

And for a few years, we had both inactivated and live measles vaccines…

The recommended immunization schedule by the AAP in the 1966 Red Book. The first measles vaccine was approved in 1963.

Next came the individual mumps (1967) and rubella (1969) vaccines and the combination MMR vaccine (1971).

And the end of routine vaccination with the smallpox vaccine (1972).

Eleven doses of four vaccines protected kids against seven vaccine-preventable diseases in 1983.

The Hib vaccine was added in 1985.

Twelve doses of five vaccines protected kids against eight vaccine-preventable diseases in 1989.
Twelve doses of five vaccines protected kids against eight vaccine-preventable diseases in 1989.

Next came the hepatitis B vaccine and expanded age ranges for the Hib vaccine.

Seventeen doses of five vaccines protected kids against eight vaccine-preventable diseases in 1989 (plus the later Td booster).
Nineteen doses of six vaccines protected kids against nine vaccine-preventable diseases in 1995.

What’s still missing?

Vaccines and protection against rotavirus, hepatitis A, chicken pox, flu, pneumococcal bacteria, meningococcal bacteria, and HPV. And no, they weren’t all added right after the National Childhood Vaccine Injury Act of 1986, another anti-vaccine myth!

Those vaccines were added to the schedule much later:

  • Varivax – a chickenpox vaccine (1995)
  • the polio shot – we began to switch back in 1996
  • VAQTA – the first hepatitis A vaccine was approved for high risk kids in 1996, but wasn’t actually added to the routine vaccine schedule until 2006
This is the immunization we used when I finished residency...

RotaShield, the first rotavirus vaccine was approved in 1998 but was quickly withdrawn in 1999 because of an increased risk of intussusception

What’s next?

  • Prevnar, with protection against pneumococcal bacteria (2000)
  • FluMist – the nasal spray flu vaccine (2004)
  • new flu shots recommendations for all healthy infants (2004)

Is the vaccine schedule starting to look familiar?

RotaTeq and Gardasil were added to the vaccine schedule the next year, in 2007.
RotaTeq and Gardasil were added to the vaccine schedule the next year, in 2007.

Since then, Prevnar was updated to include protection against 13 strains of pneumococcal bacteria. And we got a new vaccine that covers the B strain of meningococcal disease, but otherwise there haven’t been any major changes to the vaccine schedule in a while.

The 2019 vaccine schedule.
The 2019 vaccine schedule.

Do you see 72 vaccines on the schedule?

Kids today routinely get 13 vaccines that protect them 16 vaccine-preventable diseases.

Do you see 72 doses of vaccines on the schedule?

Guess what? These folks are deliberately misleading you.
Guess what? These folks are deliberately misleading you.

Kids don’t get 72 doses of vaccines today.

That’s an inflated number that’s used to scare parents. That it is a propaganda technique should be obvious, as the folks who use it don’t use the same anti-vaccine math to inflate the number of doses from the historical schedules.

Too Many Too Soon Revisited

You know how anti-vaccine folks like to say that kids get too many vaccines at too early an age these days?

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

It’s not like the ‘good old days,’ when instead of more vaccines, they just got more diseases.

But looking at the immunization schedules from the 1950s and 1960s, you should know that folks back then got a lot more vaccine doses than you have been led to believe.

Too Many Too Soon Revisited

And you know what else? Those vaccines include the “crude brew” of DPT and smallpox, which contained far more antigens per vaccine than today’s vaccines.

The 1951 immunization schedule published by the AAP.
The 1951 immunization schedule published by the AAP.

By six months, these kids got the smallpox vaccine (200 antigens) and three doses of DPT (3,002 antigens), for a total of 9,206 antigens.

And today?

They could get up to about 174 antigens, including

  • DTaP: 7 antigens * 3 doses = 21 antigens
  • IPV: 15 antigens * 3 doses = 45 antigens
  • Hib: 2 antigens * 3 doses = 6 antigens
  • Prevnar13: 14 antigens * 3 doses = 42 antigens
  • hepatitis B: 1 antigen * 3 doses = 3 antigens
  • rotavirus: 15 antigens * 3 doses = 45 antigens
  • Flu: 12 antigens * 1 dose = 12 antigens

That’s 9,032 fewer antigens or less than 2% of what they once got, even though they are protected against many more diseases!

Not worried about antigens anymore?

Just remember that in the 1950s, in addition to all of these extra antigens, except for smallpox, these vaccines were made with thimerosal and aluminum.

Not that those ingredients were dangerous then, or today. It’s just more recently that folks decided that they were scary.

But it is just important to keep in mind that it is misleading to say that kids only got 2 vaccines then, and now get 69, 72, or 74.

In fact, it’s not just misleading, it’s lying.

If you use the same anti-vaccine math, in the 1950s, they actually got at least 22 doses by age 9 or 10! And they got even more once the polio vaccine was introduced in 1955.

Vaccines don't destroy your life force...
Vaccines don’t destroy your life-force…

Anti-vaccine folks still try to downplay the number of doses of vaccines folks got back in the 1950s and 1960s though.

Why?

To scare you.

Kids do get more vaccines, but they have far fewer antigens, and more vaccines means more protection against more diseases.

In the 1950s, 60s, and 70s, kids were dying of diseases that are now vaccine preventable, including rotavirus, hepatitis A and B, chicken pox, pneumococcal meningitis, epiglottitis, Hib meningitis, and meningococcal meningitis, etc.

What about the idea that all of the extra vaccine doses were added right after the passage of the National Childhood Vaccine Injury Act of 1986?

Believe it or not, it was almost nine years, 1995, before a new vaccine (Varivax) was added to the immunization schedule. Others were slowly added after that, including:

  • hepatitis A (1996)
  • rotavirus (1998)
  • Prevnar (2000)
  • Menactra (2006)
  • Tdap (2006)
  • Gardasil (2006)

The biggest change? The one that helps boost the numbers of doses so that anti-vaccine folks can try and say that kids get 72 doses of vaccines?

That was when we started recommending flu shots for healthy kids, beginning with infants for the 2004-05 flu season. Remember, nearly a third of their list is just flu shots…

What about Hib and Hep B? They were both added right before the passage of the National Childhood Vaccine Injury Act of 1986.

Guess what?

Nothing about their little anti-vaccine memes are true.

Vaccines are safe, with few risks, and are necessary.

How Many Vaccines Did Kids Get in the 1950s?

I recently posted an immunization schedule from the 1960s to bust the myth that kids didn’t get many vaccines before the 1970 and 80s, even though they actually got multiple doses of DTP, polio, and smallpox vaccines.

But how about if we go back even earlier than that?

My uncle got polio around the time this vaccine schedule was released in 1951, but before the first polio vaccines were being routinely used.
My uncle got polio around the time this vaccine schedule was released in 1951, but before the first polio vaccines were being routinely used.

In 1951, infants got multiple doses of diphtheria, tetanus, and pertussis vaccines and the smallpox vaccine by the time they were 6 months old, with boosters through age 10 years.

Multiple doses with aluminum. And thimerosal. And far more antigens than kids are exposed to today, even though they now get many more vaccines.

“Tetanus toxoid recall injections should be continued every 3 years throughout life in dosage of 0.1cc to 0.2cc.”

AAP Report of the Committee on the Control of Infectious Diseases 1951

Oh, they also got revaccinated with the smallpox vaccine “every five years.”

And yes, most of the vaccines contained aluminum.

“The Committee recommends that all infants be immunized actively against diphtheria, pertussis, and tetanus with a course of injections of combined alum or aluminum phosphate precipitated, or aluminum hydroxide adsorbed diphtheria and tetanus toxoids containing H. pertussis vaccine. These products are considered preferable to fluid mixtures for the following reasons: (1) more prolonged antitoxic immunity produced by precipitated or adsorbed mixtures, (2) greater effectiveness as immunizers against pertussis in early infancy, and (3) less likelihood of producing systemic reactions because of lower protein content and slower absorption.”

AAP Report of the Committee on the Control of Infectious Diseases 1951

Other vaccines were also available for special situations, including rabies, typhoid, parathyphoid, and the BCG vaccine.

“Acetylsalicylic acid, 65 mg per year of age, should be given within an hour or two of injections and repeated 4 hours thereafter.”

AAP Report of the Committee on the Control of Infectious Diseases 1951

While it is likely a very big surprise to anti-vaccine folks that kids got multiple doses of DPT, tetanus, and smallpox vaccines back then, unfortunately, it means that they were susceptible to many diseases that are now vaccine-preventable.

Diseases that our kids don’t have to get, because they can be vaccinated and protected with vaccines that are safe, with few risks, and still necessary.

How Many Vaccines Did Kids Get in the 1950s?

How Many Vaccines Did Kids Get in the 1960s?

You have likely heard about the explosion in vaccines and vaccine dosages for kids, right?

Although it is easy to see that today’s counts are inflated to scare folks, it is a little harder to figure out about the good old days, when folks still got measles, mumps, Hib, hepatitis B and meningococcemia.

Did they get 2 vaccines or 5 vaccines or what?

How Many Vaccines Did Kids Get in the 1960s?

Well, maybe it isn’t that hard to figure out…

We could look in some old issues of Pediatrics and see how we used to vaccinate and protect kids back then.

And what would we find?

Kids got multiple doses of DPT, DT, polio, and smallpox vaccines in 1960.
Kids got multiple doses of DPT, DT, polio, and smallpox vaccines in 1960.

Using the same anti-vaccine math that gets us to 72 doses today, these kids in 1960 got 31 doses!

Remember, with anti-vaccine math, each DPT shot counts as 3 vaccines…

Looks like they’re going to have to fix the ad on their truck!

And all of the propaganda they put out trying to scare folks into thinking kids get so many more vaccines than they used too.
