The MMR vaccine has been studied in more than 23 million children across six decades, much of that work funded by the department @SecKennedy now runs. Last night on CNN he told American parents it is hard to determine whether it is safe. He is lying. Here is the evidence. 🧵

Japan is also the best natural experiment ever run on MMR and autism. A total population study in Yokohama tracked every child born from 1988 to 1996. Children born in 1993 or later got zero MMR doses. Autism incidence in those cohorts was 97 to 161 per 10,000, roughly double the 48 to 86 in the earlier cohorts that received MMR. Autism kept rising after the withdrawal, on the same trajectory as every country that kept vaccinating. 33 years later, Japan's national insurance data show 3.26% of children born in 2014 diagnosed with autism by age 5, among the highest rates reported anywhere. None of those children received an MMR. The one country that eliminated MMR has the same autism rate as the countries that kept it. 3/

I always enjoy my conversations with @CitizenCohn - a very sharp thinker & writer. We talked about the vaccine executive order for his latest, which follows it from the Oval Office to the pediatrician's office. Worth reading: @BulwarkOnline

The “covered up” data was published in the New England Journal of Medicine in September 2021, where it has sat, publicly, for five years. It shows vaccinated women miscarried at the same rate as everyone else, about 1 in 8. The 82% figure comes from a denominator error: it counts only pregnancies that had already ended, months into a nine-month process, which at that point meant mostly the losses. The healthy pregnancies were still ongoing. A cover-up conducted by publication in the world’s most-read medical journal is a genuinely novel approach.

Two senators released a January 2021 text from Anthony Fauci this week, in which he told colleagues that fever after the second vaccine dose could theoretically be associated with miscarriage in the first trimester. The text is circulating as evidence that covid vaccines cause miscarriage. This question was studied extensively in the years that followed, and the results deserve to circulate at least as widely as the text. 1/
