Risk of myocarditis (heart inflammation) in men under 40 years old is higher after 2 doses of an mRNA vaccine than from SARS-CoV-2 itself, particularly after Moderna where it's many times higher: https://vinayprasadmdmph.substack.com/p/uk-now-reports-myoca...

HN discussionIn men <40 years old, 2 doses of either of the mRNA vaccines are more likely than SARS-CoV-2 to give you myocarditis. Pfizer is only a little higher, but Moderna is several times higher. https://vinayprasadmdmph.substack.com/p/uk-now-reports-myoca... (second image, source is linked directly above it)

HN discussionThe diabetes study you cited appears to be junk science. I'm not claiming that COVID-19 absolutely doesn't cause diabetes, just that we won't know one way or another until larger studies are performed with proper methods. https://vinayprasadmdmph.substack.com/p/does-covid19-cause-d...

HN discussionNo. Cloth masks are understudied and probably don’t do much. What does do a lot, probably, is a dynamic where millions of people wearing ineffective masks thinking they are effective, and making bad choices entirely due to that bad assumption, like not wearing an N95, closing distance with people, or going indoors when it could have been avoided. https://vinayprasadmdmph.substack.com/p/mask-studies-reach-a...

HN discussion> Joe apparently said you shouldn't worry about taking the vaccine if you're young and healthy, and when he apologized he called himself a moron and said he was talking about OTHER people.

HN discussionThey can't address what he actually said for the same reason anyone likes to refute a strawman argument instead of addressing the real argument. I think the officials are so afraid that any discussion of nuance [1] would frighten people away from the vaccines that they simply avoid talking about it entirely, and sometimes call to outright suppress any such discussions as "misinformation" and label these people as "a…

HN discussionMyocarditis risk stratified by gender, age group, vaccine and infection: https://vinayprasadmdmph.substack.com/p/uk-now-reports-myoca... Males under 40 roughly have the highest risk from multiple Moderna doses, followed by infection, followed by two Astra doses, followed by two Pfizer doses. I expect two COVID infections would increase the risk like it seems to do with the vaccines.

HN discussionHave a look here: https://vinayprasadmdmph.substack.com/p/vaccine-effectivenes... tl;dr Vaccine effectiveness around 15% for me at this point. So it was the natural immune response (gasp!), combined hospitalization rates across the world reflects this.

HN discussionVinay Prasad seems to be a contrarian who recently compared the US COVID-19 policies to Hitler's Germany[1]. In the article you linked, he's citing his own study on cloth masks. Most would agree that cloth masks are the least effective masking option at stopping viral spread. Cloth masking is just the easiest target to attack in an anti-mask agenda. He also implies doctor's have inherent bias against HCQ and Ivermec…
