How antivaxxers weaponize vaccine safety studies to falsely portray vaccines as dangerous, part 2: The children

A few months ago, I wrote about how antivaxxers misrepresent vaccine safety studies to portray vaccines as dangerous, using a large study of outcomes in adults as an example.. They're doing it again, but this time it's a large study of COVID-19 vaccines in children.

The New York Times promotes “lab leak” conspiracy theories

Last week, the New York Times ran an op-ed by Alina Chan, Queen of lab leak conspiracy theories and then gave it a prominent place in its Sunday Magazine this weekend. How is it wrong? Let me count the ways.

Generic Drugs: Are they different?

Standards in place for generic drugs should give consumers confidence that these products are just as effective as their brand-name equivalent.

Dr. Vinay Prasad vs. a VAERS study finding more reports of vaccine injury in red states

Dr. Vinay Prasad attacks an epidemiological study published in JAMA Open Network reporting that people in red states are more likely to report vaccine injuries, claiming that a more rigorous study would "not be difficult," when he knows that it would be very difficult.

How antivaxxers weaponize vaccine safety studies to falsely portray vaccines as dangerous

Antivaxxers have weaponized a huge multinational vaccine safety study of 99 million patient records that found rare adverse events and concluded that the risks of COVID-19 vaccines outweigh the benefits. How? A combination of the Nirvana fallacy and spin.

He pushed hydroxychloroquine three years ago: Harvey Risch and false claim of “turbo cancers” caused by COVID-19 vaccines

Last week, I discussed Dr. William Makis' false claims of "turbo cancers" due to COVID-19 vaccines. Now it's hydroxychloroquine-promoting epidemiologist Harvey Risch's turn.

Peter Gøtzsche teams with an antivaxxer to exaggerate the harms of COVID-19 vaccines

Peter Gøtzsche, formerly leader of the Nordic Cochrane Center, has teamed with Maryanne Demasi to write a systematic review of the "harms" of COVID-19 vaccination. Besides accepting the highly dubious methodology behind one study, their preprint is yet another example of how EBM can be corrupted to promote antivax ideas.

Autism prevalence increases to 1 in 38, and antivaxxers blame vaccines without using the word “vaccine”

The CDC updated its estimates for the prevalence of autism spectrum disorders. Predictably, antivaxxers blame the increasing prevalence of ASDs reported, particularly in Black children, on "environmental factors," which is antivax code for, "Vaccines are to blame."

The rise and fall of the lab leak hypothesis for the origin of SARS-CoV-2

Two new studies were published last week that strongly support a natural zoonotic origin for COVID-19 centered at the wet market in Wuhan, China. Naturally, lab leak proponents soberly considered this new evidence and thought about changing their minds. Just kidding! They doubled down on the conspiracy mongering, because of course they did.

How the DMED works

Antivaxxers misuse the Defense Medical Epidemiology Database to demonize COVID-19 vaccines

Over the last couple of weeks, a claim that the Defense Medical Epidemiology Database (DMED) shows that COVID-19 vaccines have caused a massive increase in cancer, neurological, and cardiovascular diseases in military personnel has gone viral. A closer look shows that the increases are almost certainly spurious and due to underreporting in previous years.
