Are There Any Long-Term Studies On Vaccine Safety?

Vaccines are evaluated for safety in studies when they get approved.

Is that enough?

“I would like to see us do more long-term safety research studies on these large groups of children, so then we can determine that they are safe in the long-term.”

Bob Sears

Apparently not for everyone…

Are There Any Long-Term Studies On Vaccine Safety?

Of course, vaccines continue to be evaluated for safety after they approved, using passive and active vaccine safety systems and long-term post-marketing safety studies.

“We learn about a vaccine’s safety during clinical trials before it is licensed, and monitor it continually as millions of doses are administered after it is licensed. We also know there is not a plausible biologic reason to believe vaccines would cause any serious long-term effects. Based on more than 50 years of experience with vaccines, we can say that the likelihood that a vaccine will cause unanticipated long-term problems is extremely low.”

These long term studies on vaccine safety have looked at:

Have you heard about these studies before?

When they talk about SV40, do anti-vaccine folks mention this long-term study?

Probably not.

Anti-vaccine folks either aren’t aware of, or just don’t want you to know about these types of long-term studies.

It’s easier to scare you away from vaccinating and protecting your kids if they make you believe that vaccines aren’t tested together, aren’t tested with placebos, aren’t tested vs unvaccinated kids, and aren’t tested for long periods of time.

They are!

Are Your Kids at High Risk for Flu Complications?

Everyone should get a flu vaccine each year, as long as they are at least six months old and have no true contraindications.

That has been the recommendation since at least the 2010-11 flu season.

And while most kids get vaccinated, not all do.

Are Your Kids at High Risk for Flu Complications?

There are some kids, those at high risk for flu complications, who definitely shouldn’t skip or delay their flu vaccine.

  • all children aged 6 through 59 months (younger than age 5 years);
  • children who have chronic medical conditions, including pulmonary (such as asthma and cystic fibrosis), cardiovascular (excluding isolated hypertension), genetic (Down syndrome), renal, hepatic, neurologic (cerebral palsy, epilepsy, stroke, muscular dystrophy, and spina bifida, etc.), hematologic (sickle cell disease), or metabolic disorders (including diabetes mellitus and mitochondrial disorders);
  • children who are immunocompromised due to any cause (including immunosuppression caused by medications or by HIV infection);
  • teens who are or will be pregnant during the influenza season;
  • children and adolescents (aged 6 months through 18 years) who are receiving aspirin- or salicylate-containing medications (like for Kawasaki disease) and who might be at risk for experiencing Reye syndrome after influenza virus infection;
  • residents of nursing homes and other long-term care facilities;
  • American Indians/Alaska Natives;
  • children who are extremely obese (body mass index ≥40).

You also shouldn’t skip or delay getting a flu vaccine if your:

  • kids are household contacts of children aged ≤59 months (i.e., aged <5 years) and adults aged ≥50 years, particularly contacts of children aged <6 months;
  • kids are household contacts of someone with a medical condition that puts them at higher risk for severe complications from influenza.

Again, since everyone should get a flu vaccine, these higher risk classes shouldn’t determine whether or not you vaccinate your kids, but they might influence the timing.

Again, don’t skip your child’s flu vaccine because they aren’t in a flu high risk group.

In most flu seasons, about 80% of children with the flu who die are not vaccinated. And many of them will be otherwise healthy, without an underlying high risk medical condition.

Get your child vaccinated against the flu. And if they are in a high risk group, make sure you do it well before flu season starts and maybe as soon as flu vaccine becomes available in your area.
