Congenital heart disease has been known since at least Leonardo da Vinci's time. That a social media influencer didn't know that, is not enough evidence to assert that it doesn't exist.

Context – 100k offered “no joke” to lower a mask – won’t donate 50k to a children’s charity at Christmas (tax deductible) for someone to prep and debate him. (Further context he asked me to debate via DM)

“There is no solid evidence polio was ever a virus”

The Salk vaccine (IPV) is inactivated polio virus & the Sabin vaccine (OPV) is attenuated polio virus. The vaccines are literally made from polio virus, which I posit is evidence polio virus is indeed a thing that exists. https://t.co/SThLUsSfnJ

In the 10 years after the vaccine was recommended in 2006 in the United States, quadrivalent type HPV infections decreased by 86% in female teens aged 14 to 19 years and 71% in women in their early 20s.

Steve ("Cherry"-picking) Kirsch now going after Brian Deer who exposed the Wakefield "MMR causes autism" fraud over 20 years ago

I'm blocked by Kirsch for posting images of harms caused to children by the diseases vaccines protect against. He is a bully and a danger to children https://t.co/WrkxzDElqu

You're too funny, Steve. So Caroline spells paediatric like a New Zealander but spells centre and caesarean like an American and refers to a product not available in NZ? And as a paediatric nurse, she doesn't know that whooping cough is most severe in infants under 6 months. https://t.co/vYdFypYwqY

Anti-vaxxer @stkirsch dumpster-dives into debunked anti- #vaccine tropes like denying the settled science that vaccines do not cause #autism. https://t.co/4XGiREkipp #VaccinesWork

I already explained why that isn't a valid argument for linking autism to MMR vaccines, Steve. I am surprised a smart guy like you doesn't understand.https://t.co/K6uAcvOIir

If you never intend on honestly engaging with people you disagree with, harass people who debate you, intentionally misrepresent statistics, and stir up fear for financial gain, don’t be surprised if nobody wants to engage with you. pic.twitter.com/WN6YrcIUva

This study was literally retracted from JAMA paediatrics – because it is really, really stupid. The methods used is NOT how we measure CO2 retention. The only thing they proved is that people exhale CO2 (groundbreaking!)

My husband, a former pilot, just asked me (in response to this 👇🏼) – if Steve Kirsch is on a plane and there's a sudden decompression such that masks drop from the ceiling above, does he put one on? 😱 #MasksWork pic.twitter.com/aIAXcpbBgt

Steve Kirsch said he offered $100,000 to a fellow passenger if she took off her mask. But he didn't realize he came across as the seatmate from hell. https://t.co/9ECruubWkU via @HuffPostPol
