Vaccine Information Statements

Vaccine Information Statements (VISs) are produced by the CDC and help vaccine providers inform patients about the benefits and risks of the vaccines they are getting.

In fact, under the National Vaccine Childhood Injury Act, vaccine providers are required to give out a VIS before giving a vaccine, including those for:

  • Diphtheria, tetanus and pertussis containing vaccines (DTaP, DT, Td, and Tdap)
  • Haemophilus influenzae type b (Hib)
  • Hepatitis A
  • Hepatitis B
  • Human Papillomavirus (HPV)
  • Influenza (both Inactivated and Live, Intranasal vaccines)
  • MMR
  • MMRV
  • Meningococcal
  • Pneumococcal Conjugate (PCV13)
  • Polio
  • Rotavirus
  • Varicella

Unlike the package insert for a vaccine, “VISs are based on the ACIP’s recommendations, which occasionally differ from those made by the manufacturer. These differences may involve adverse events. Package inserts generally tend to include all adverse events that were temporally associated with a vaccine during clinical trials, whereas ACIP tends to recognize only those believed to be causally linked to the vaccine.” That makes the  VIS a better tool to use when doing your research on a vaccine.

Thimerosal in Vaccines

Although it was never actually linked to any real side effects, thimerosal (mercury) was removed from almost all childhood vaccines in 1999.

Thimerosal, a preservative, only remained in flu vaccines for a few years, but thimerosal free flu vaccines have been available since 2003. And this year, at least “120 million doses of thimerosal-free or preservative-free influenza vaccine will be produced.” That means that over 75% of flu shots are thimerosal free, leaving only some multi-dose vials of flu shots to still have thimerosal, but making it easy to avoid if you want to.

Although most anti-vaccine groups have moved on to other conspiracy theories to scare parents, some still falsely claim that vaccines continue to be made with thimerosal and that thimerosal is dangerous.
