According to a large new study completed by Kaiser Permanente, pregnant women receiving prenatal tetanus, diphtheria toxoid, and acellular pertussis (Tdap) do not increase their child’s likelihood of developing autism. The study is the first to research the effects of prenatal vaccines and autism in children. Research completed supports the CDC recommendation that all pregnant women receive the Tdap. In the study, unexposed women to Tdap had a higher incidence of having a child with Autism.

The author of the study noted in the discussion, “In this large retrospective observational cohort study of 81 993 pairs of diverse pregnant women and their children, we found no evidence of increased risk for ASD diagnosis associated with Tdap vaccination during pregnancy.”

Anti-vaccine proponents have warned women around the world to avoid vaccinations during pregnancy. Many link preservatives found in vaccines to causing autism.

In order to confirm or dispel the rumors, studies such as the one completed must be done. According to the authors, the study is one of the largest completed to research if a link exists.

As a result of the speculation by those critical of vaccines, the study completed was a retrospective cohort from January 2011 through December 2014.

Researchers said the vaccinated women vaccinated were more likely to be Asian American or Pacific Islander, first-time mothers, have a higher education, receive influenza vaccination prenatally, and give birth at term.

After researchers completed the study, they found the vaccinated women had fewer children diagnosed with Autism than the unexposed women.

Vaccinated women’s incidence of autism in the child is 3.78 per 1,000 person-years. Unvaccinated women’s incidence of autism in the child was slightly higher at 4.05 per 1000 person-years.

Researchers concluded that the study indicated there is no direct correlation between the Tdap and autism. However, the authors mentioned the need for more studies to confirm their conclusion. Furthermore, to strengthen the outcome of the study, the authors recommend additional studies with longer follow-up periods and more birth years.

For now, there is compelling evidence for pregnant women that vaccines are safe during pregnancy. Additionally, women should not worry that the vaccine will cause their child to develop autism. The CDC recommends all pregnant women receive vaccinations to protect their baby from serious diseases.

Finally, Keep your babies, safe mommas!

Vaccinate yourself to protect your child.

  • Think of all the time, money, and resources that have been wasted with study after study that does nothing but verify what we already know: VACCINES DO NOT CAUSE AUTISM. Agaiin. Thanks for nothing, Wakefield.

  • right?! How many MORE studies do we need. I really wonder. I mean this study was enormous in scope – so this should be more reliable than the 11 kids Wakefield “researched”

  • frostysnowman

    It doesn’t count since it was done by “Big Pharma”. /s

  • Nope

  • Raging Bee

    This is nothing more than another wave of the same old anti-vaccine hysteria we’ve been dealing with since vaccines were first invented. No amount of studies will change all that much in the short run. Quite frankly, I’m kinda surprised the neo-Luddites haven’t just made up a new genre of scare-stories by now…

  • Oh they have – now they make billboards that say “vaccines cause death”

  • Raging Bee

    That’s it? No elaboration?

  • No, very little elaboration. THe photo they use is of a child that died – but his autopsy says “natural Death”. There is zero evidence he died from the MMR vaccine

    Did they count the miscarriages?

  • What do miscarriages have to do with autism?

  • Cindy Ray

    Pregnant women often miscarry after vaccines.

  • O rly? Kindly provide a link to a peer-reviewed obstetrics journal. No blogs. No self-published books. No unreviewed research papers.

  • From the CDC article: “This study does not quantify the risk of miscarriage and does not prove that flu vaccine was the cause of the miscarriage. Earlier studies have not found a link between flu vaccination and miscarriage.”
