Note: vaccines that do not completely prevent transmission can still reduce transmission. And often do. That's why we still don't have polio and communities with high pertussis vacicne rates have less pertussis. www.immunize.org/wp-content/u...

Mentions Verstraeten 2003 (that when published found no link between thimerosal in vaccines and autism).
Only studied that found an issue - by Geiers, known for bad science and for abusing autistic children (and lying about it).

Cases came down from peak in 1985 to lower case last decade. Mainly among young adults. Decline before universal birth dose.
Note: this is not the right measure. Where are infections of children?
Also: big decline after 1991, so she's wrong.

Their own surveys show overwhelming number of parents vaccinated on schedule, including for hepatitis B. 2014 - 5% refused birth dose, 2025, 13% skip.
So, why change?

Apparently they're using a 2002 and 2013 IOM report and a 2014 Oregon survey, as well as a KFF. In 2002 1/3 of parents expressed concerns - but that's not exactly opposition or recent.

An anti-vaccine author took advantage of this person's ignorance.
When there's a vaccine available, the correct control for a new version is the old vaccine, not a saline placebo. Also, DTaP, for example, is a 3 dose series over 6 months. So the trial is not only 28 days.

On my Facebook I added this paragraph emphasizing the whole thing is junk (and of course, as you point out, treating autism as subhuman is just wrong). I didn’t have space here. But I agree.

Explains Colleen Thomas, the advocate from @hoosiersvaccinate.bsky.social: what about your diabetic cousin? Someone who has cancer? Remember that vaccination is a form of kindness: you help not just yourself but also others.

Reminder: the President may be allowing his secretary to undermine access to vaccines for others and promote anti vaccine misinformation, but he himself is fully vaccinated, including this year’s flu and Covid vaccine.
In this, do as the president does, not as his secretary ‘s ACIP minions say.

How antivaccine groups mislead people, #4694: the actual report said the CDC performed well, but suggested improvements; the CHD article misrepresented it by saying it fumbled safety, which the report did not say or imply.

Reminder: informed consent is always required for a vaccine. Shared clinical decision making just creates confusion and decreases uptake, without improving informed consent.
And if you use this approach towards childhood vaccines, you will exacerbate the Trump/Kennety outbreaks.
