3 Myth Busters for Vaccine-Hesitant Parents


Controversy has been sparked now that anti-vaccine activist Robert F. Kennedy Jr. claims that Donald Trump has asked him to chair a new commission on vaccine safety.

Controversy has been sparked now that anti-vaccine activist Robert F. Kennedy Jr. claims that Donald Trump has asked him to chair a new commission on vaccine safety. This is a great opportunity for pharmacists to counsel patients, and especially parents on the benefits of vaccines. Check out these 5 vaccine myths that can easily be busted by pharmacists through communitywide public health education.

  • Myth: Vaccines cause autism.

Fact: Studies have proven there is no link between vaccines and autism.

The American Academy of Pediatrics (AAP) emphasizes that numerous clinical studies have demonstrated that there is no link between receiving vaccines and developing autism.1,2 The study published in the journal Lancet in 1998 with principal author Dr. Andrew Wakefield suggesting that the measles-mumps-rubella (MMR) vaccine might be linked with autism was retracted in 2010 since the findings were false.3 The British General Medical Council in the United Kingdom reported that Wakefield acted unethically and dishonestly in conducting research. This study has sparked unnecessary concerns among parents, and pharmacists should reiterate the robust evidence showing that there is no link between vaccines and autism.

  • Myth: Thimerosal is harmful.

Fact: Studies have demonstrated that vaccine ingredients such as thimerosal (mercury-based preservative) do not cause autism. Between 1999 and 2001 thimerosal was removed or reduced to trace amounts in all childhood immunizations except for some flu vaccines as a precaution before studies were conducted showing that it is not harmful.4 Educate patients that vaccines are actively monitored by the Food and Drug Administration and the Centers for Disease Control and Prevention (CDC).

  • Myth: Children should not receive multiple vaccines at the same time.

Fact: The currently recommended schedule is safe and effective and endorsed by the AAP and the CDC. Delaying vaccines leaves children at risk of contracting diseases. Children too young to receive vaccines are left vulnerable to serious illness from unvaccinated individuals. The CDC recommends vaccinations before the age of 2 years to protect children against 14 infectious diseases (See Table). Studies have demonstrated that receiving several vaccines at the same time does not cause any chronic health problems.

Hepatitis A

Hepatitis B




Haemophilus influenza type B




Pneumococcal disease

Pharmacists can collaborate with pediatricians to educate parents on the importance of childhood vaccines. Provide the CDC’s childhood vaccine chart to parents as an educational tool. Additionally, it is important to educate the new federal commission on immunizations to protect children from serious diseases. Becoming involved in both the state and federal legislative process can help to ensure that vaccine myths are dispelled. The AAP says it best: “Vaccines are safe. Vaccines are effective. Vaccines save lives.”2
