“None of the 72 vaccines mandated for children has been safety tested in preclinical studies against a placebo" says RFK Jr Shocking if true BUT... it's not There are not 72 mandated vaccines ❌ Many of them HAVE been tested against placebo ✅

105 controlled vaccine trials. 110 years. 1.8M participants. All in one live, crowd-sourced sheet. Built by clinicians, pharmacists, researchers, and anonymous contributors to counter the myth that vaccines weren’t tested with controls. Even in a noisy world, quiet work breaks

Well no, it’s the opposite: Covid vaccination in pregnancy reduced maternal morbidity and mortality, and improved neonatal outcomes. Here are some summary links medicine.yale.edu/news-article/t… thelancet.com/journals/lanep…

As best as I can tell? 1. New guidelines don’t consider the benefits of vaccinating vs long COVID 2. No clarity who determines risk factors such as “physical inactivity” 3. Regarding vaccinating healthy teens/adults, now the decision is no longer between you and your doctor

Effectively therefore access to the annual Covid immunizations or boosters would be denied to healthy adults and teens, so that the US Government is now making decisions that formerly were made between an individual or parent and their doctor. So much for “health freedom”

Wolfgang Ketterle, a Nobel laureate physicist at MIT was once asked why he stayed in the US despite generous offers to return to Germany. Because, he said, his students come from every corner of the globe, and that intellectual diversity makes his science so much better

If you go back far enough in your family tree, you discover that you, too, are an immigrant... And if you think hard enough about what makes this country great, you realize that our success depends on welcoming gritty strivers nytimes.com/2025/05/22/us/…

Non-physicians and non-scientists making national healthcare decisions is not policy—it’s practicing medicine without a license. It’s as dangerous as me trying to fly a plane without a pilot’s license. We’d never accept that in aviation. Why are we accepting it in medicine?

The effects of Covid during pregnancy are devastating in terms of maternal morbidity and mortality; they are preventable by vaccination Newer data from Penn Medicine find that Covid vaccines prevent long COVID in children and adolescents

'Shifting from vaccine mandates to outright prohibitions does not reflect medical freedom; it represents a different form of government intervention, one that restricts individual choice and access to evidence-based care.'

America’s Obstetricians come out “extremely disappointed” by HHS / FDA decision to deny women the choice to get the Covid vaccine during pregnancy I cant imagine ever having made such a decision without consulting with ACOG first It’s pretty bad acog.org/news/news-rele…

Gutting the NIH and handing $500 million to the MAHA Commission to “study the causes of chronic illness” isn’t reform, it’s reckless. We already have decades of rigorous, peer reviewed research on the causes and pathophysiology of chronic disease. From obesity and diabetes to

Thanks to Brenda Goodman for this excellent piece. A team of us compiled data on controlled vaccine trials: 258 so far (~1/2 of which used inert placebo), covering 45 antigens and 2.5M participants. Claims that vaccines lack placebo trials are false. edition.cnn.com/2025/06/05/hea…

Science just got sidelined. This isn’t about vaccine safety or restoring confidence —it’s about political agendas endangering public health. We should all be alarmed.

Today RFK Jr took the single biggest step towards destroying childhood vaccines When The New York Times asked me in December whether RFK could kill the vaccine program - I said he’d have to remove CDCs ACIP Welp… that’s exactly what he just did today Not good medpagetoday.com/infectiousdise…
