Have you heard that the FDA and CDC tell people to exaggerate disease statistics, especially morbidity and mortality statistics of vaccine-preventable diseases?
Why would they do that?
Anti-vaccine folks think that they do it to scare folks into getting vaccinated and protected. While it’s just anti-vaccine propaganda, this is actually one anti-vaccine myth that I wish were true, because then it might mean that 185 kids didn’t die in last year’s flu season.
Do the FDA and CDC Tell People to Exaggerate Disease Statistics?
It’s no secret that more people look to get vaccinated during a severe flu season.
The purpose of these training materials is to reinforce that it is very important to educate people about the dangers of getting the flu, but that it is also very important to not go too far and scare them.
Be concerned enough so that you get vaccinated, but don’t worry too much…
But don’t you have to exaggerate things to get people concerned enough to get vaccinated?
Do you know how many kids, mostly unvaccinated and many otherwise healthy, die during a typical flu season. If you did, and you understood that the flu vaccines are safe, then you wouldn’t think of skipping it.
Get your family vaccinated and protected against the flu.
There’s no playbook that experts are using to try and trick you into getting vaccinated. Just folks trying to increase awareness, so that everyone understands that vaccines are safe and necessary, and they ignore anti-vaccine propaganda.
While I made sure to get my flu shot well before the start of flu season, it is not too late to get vaccinated and protected.
Believe it or not, it’s not too late.
Is It Too Late to Get a Flu Shot?
Why would anyone think it could be too late?
“Balancing considerations regarding the unpredictability of timing of onset of the influenza season and concerns that vaccine-induced immunity might wane over the course of a season, it is recommended that vaccination should be offered by the end of October.”
While it is a good idea to get vaccinated and protected well before flu season starts, this is one of those better late than never kind of things.
Have you gotten a flu vaccine yet?
“CDC recommends that people get a flu vaccine by the end of October. Getting vaccinated later, however, can still be beneficial. As long as flu viruses are circulating, it is not too late to get vaccinated, even in January or later. While seasonal flu outbreaks can happen as early as October, most of the time flu activity peaks between December and February, although activity can last as late as May.”
CDC on Misconceptions about Seasonal Flu and Flu Vaccines
Then it’s not too late.
Get vaccinated and protected for the rest of the flu season.
But don’t wait much longer or you will risk getting the flu before your flu vaccine has a chance to start working.
We know that pregnant women are supposed to get a flu vaccine.
Although recommendations on exactly when to get it have changed over the years, it has been a universal recommendation since at least the 1994-95 flu season.
But why?
How Does a Mother’s Flu Shot Protect a Newborn Baby?
One obvious way that a flu shot provides protection during pregnancy is that it reduces your risk of getting the flu while you are pregnant.
A flu shot during your pregnancy protects both you and your baby.
That’s good, as having the flu while you are pregnant can lead to preterm labor, a premature birth, birth defects, or a miscarriage. And of course, the flu can be life-threatening for pregnant women.
Getting a flu shot while you are pregnant can also help to make sure that you don’t get the flu after your baby is born, which not only keeps you healthy, but decreases the chance that your baby will be exposed to the flu. After all, if you get the flu, no matter how much you try to cover your cough and wash your hands, there is a good chance that you will give it to your baby.
And since babies can’t get flu shots of their own until they are at least six months old, a flu shot during pregnancy helps to make sure that your baby gets some of antibodies to protect them from the flu.
“When you get a flu shot, your body makes antibodies that also pass to your fetus. This means your baby has protection against the flu after birth. This is important because infants less than 6 months of age are too young to get the flu shot.”
Frequently Asked Questions for Patients Concerning Influenza (Flu) Vaccination During Pregnancy
Do you have to wait until late in your pregnancy to make sure that the most antibodies get passed to your baby?
While that might seem like a good idea, especially since that’s what we do for the Tdap vaccine and protection against pertussis, there are several reasons that we don’t do that with the flu vaccine, including that:
pregnant mothers need the protection before flu season hits, so waiting would not be safe and could mean that you get sick with the flu before getting your shot
protection from the flu vaccine shouldn’t wane or wear off so quickly that you need to get it later, after all, the earliest that you can get vaccinated is when flu vaccines first become available in August or September and that should provide good protection past the peak of flu season
When you get your flu shot while pregnant is going to have more to do with when you got pregnant in relation to the start of flu season more than anything else.
“The flu shot can be safely given during any trimester. Pregnant women can get the flu shot at any point during the flu season (typically October through May). Pregnant women should get the shot as soon as possible when it becomes available. If you are pregnant, talk with your obstetrician–gynecologist (ob-gyn) or other health care provider about getting the flu shot.”
Frequently Asked Questions for Patients Concerning Influenza (Flu) Vaccination During Pregnancy
Most importantly, remember that flu shots are considered an “essential component of prenatal care.”
While everyone should get a flu vaccine each year, since pregnant women are in a high risk group for flu complications, you should especially make sure that you get vaccinated and protected if you are pregnant. Everyone around you should get vaccinated too!
After decades with a single type of flu vaccine – the flu shot – there are now many different kinds of flu vaccines that many of us can choose from. And your choices are not just between the nasal spray flu vaccine vs a flu shot. There are also a lot of different kinds of flu shots available now.

Having choices is nice.
It would be also be nice to have a little more guidance on what to do with these choices.
It is actually easy to start by asking which one you should get for your kids, as many of these flu vaccine options are only available for adults and seniors.
Flu Vaccine Options
Before you start thinking too long and hard about potential options, keep in mind that you might not have as many options as you think.
“Not all products are likely to be uniformly available in any practice setting or locality. Vaccination should not be delayed in order to obtain a specific product when an appropriate one is already available.”
Prevention and Control of Seasonal Influenza with Vaccines: Recommendations of the Advisory Committee on Immunization Practices—United States, 2018–19 Influenza Season
Doctors and clinics might not stock multiple brands or types of flu vaccines, so you might have to get whatever flu vaccine that they have available.
“Within these guidelines and approved indications, where more than one type of vaccine is appropriate and available, no preferential recommendation is made for use of any influenza vaccine product over another.”
Prevention and Control of Seasonal Influenza with Vaccines: Recommendations of the Advisory Committee on Immunization Practices—United States, 2018–19 Influenza Season
And that’s okay. In most cases, there haven’t been head to head studies showing that one flu vaccine is better than another.
Flu Vaccine Options for Kids
Still, since these options might be available to you, it is good to know about them.
This year, younger kids, between the ages of 6 months and 3 years, can either get:
FluLaval Quadrilvalent
Fluarix Quadrivalent
Fluzone Quadrivalent Pediatric
While you are unlikely to notice a difference, both FluLaval and Fluarix are given at a 0.5ml dose containing 15 µg of HA per vaccine virus, while Fluzone is given at a 0.25ml dose containing 7.5 µg of HA per vaccine virus. Why the difference? “Safety and reactogenicity were similar between the two vaccines,” even at the different doses.
Basically, these are just different brands of the same type of flu shot.
There are even more options as your kids get older though, including Fluzone Quadrivalent (age three and above), Afluria Quadrivalent or Trivalent (age three and above), Flucelvax Quadrivalent (age four and above), FluLaval and Fluarix.
Of these, some folks wonder if Flucelvax, since it isn’t made in chicken eggs, might be more effective than the others. Remember, one of the things that are thought to make the flu vaccine less effective than most other vaccines is that they are made in eggs, leading to mutations. And there is actually some evidence that those flu vaccines that are not made in eggs might be more effective.
“And the University of Pittsburgh Medical Center is taking that a step further, saying it will only be buying the two egg-free vaccines on the market: Flucelvax and FluBlok. That’s because there is some evidence these two formulations may work better than the older vaccines grown in eggs, said Dr. Richard Zimmerman, who advises the UPMC Influenza Committee.”
Guidance on which flu vaccine to get: Shots for kids, maybe go egg-free
Again, remember that the CDC has made “no preferential recommendation” for one flu vaccine over another. Why not? We don’t have enough information to make that kind of recommendation.
Should parents only ask for Flucelvax? That would only work if they made enough doses for every kid to get vaccinated, which they didn’t. Should you hold out until you can find FluceIvax for your kids? No, since doing that might leave them unvaccinated once flu season hits.
What else should you know about your flu vaccine options? While over 80% of flu vaccines are now thimerosal free, most of these flu vaccines are still available in multi-dose vials with thimerosal.
Also thimerosal free, this year, Flumist is back as an option. It is available for healthy kids who are at least two years old. Although the AAP has issued a preference for flu shots this year, the ACIP says that kids can get either Flumist or a flu shot.
What about if your kids are allergic to eggs?
“Persons who report having had reactions to egg involving symptoms other than urticaria (hives), such as angioedema, respiratory distress, lightheadedness, or recurrent emesis; or who required epinephrine or another emergency medical intervention, may similarly receive any licensed, recommended, and age-appropriate influenza vaccine (i.e., any IIV, RIV4, or LAIV4) that is otherwise appropriate for their health status.”
Prevention and Control of Seasonal Influenza with Vaccines: Recommendations of the Advisory Committee on Immunization Practices—United States, 2018–19 Influenza Season
Unless they had a severe allergic reaction to a previous flu vaccine, they can get any available flu vaccine, especially if the previous reaction was only hives or they are able to eat eggs.
What if you want a flu vaccine without aluminum? Take your pick. While it would be safe it was, aluminum is not an ingredient in flu vaccines.
Flu Vaccine Options for Adults
In addition to all of the flu vaccines available for older kids, adults have a few more options:
Afluria Quadrivalent or Trivalent can be given by jet injector to those between the ages of 18 and 64 years
Flublok Quadrivalent – a recombinant flu shot that can be given to those who are at least 18 years old
Fluzone High-Dose – a trivalent flu shot with a higher dose of flu virus antigens (4 times the amount of antigen as a regular flu shot) that is available for seniors who are at least 65 years old
Fluad – a trivalent flu shot with an adjuvant that is available for seniors who are at least 65 years old
Why get a flu vaccine with a jet injector instead of a standard needle? High-pressure jet injectors don’t use needles!
Like FluceIvax, Flublok is not made in chicken eggs. The recombinant hemagglutinin(HA) proteins are made in insect cell lines. Does Flublok work better than egg based flu vaccines? That’s the theory, but again, there is no preference for one of these vaccines over another.
Seniors have even more choices.
Should they get Fluzone High-Dose, Fluad, or one of the other flu vaccines? Both have been shown to be more effective than standard flu vaccines in seniors, but they have not been compared against each other.
“In a Canadian observational study of 282 people aged 65 years and older conducted during the 2011-12 season, Fluad was 63% more effective than regular-dose unadjuvanted flu shots.”
CDC on People 65 Years and Older & Influenza
But neither Fluzone High-Dose nor Fluad are quadrivalent, so only protect against three flu virus strains.
Is there a quadrivalent flu shot for older adults that might work better than standard flu shots?
Yes. FluceIvax and Flublok are non-egg based quadrivalent flu shots that might be more effective than standard flu vaccines.
So are you more confused now that you know you have so many options? Just remember that for most people, the mistake isn’t about choosing the right flu vaccine, it is about not getting vaccinated.
What to Know About Your Flu Vaccine Options
While it might seem like you have a lot more options in a flu vaccine this year and that some might be more effective than others, keep in mind that availability will likely greatly limit these “options.”
And the best flu vaccine is the one that you actually get, as it will be the one that reduces your risk of getting the flu. Missing your chance to get vaccinated and protected because you are waiting for a specific brand or type of flu vaccine isn’t going to help keep the flu away.
