"Myocarditis is more common after severe acute respiratory syndrome coronavirus 2 infection than after COVID-19 vaccination, but the risks in younger people and after sequential vaccine doses are less certain."
The study size is 43M people.
- puffoflogic 4y agoAttaching that quote to that study, without the appropriate context, is disinformation. The study didn't look at the risk of COVID infection in unvaccinated individuals. All this study proved is that COVID infection can trigger cardiovascular issues in vaccinated people. It doesn't indicate in any way that the cardiovascular issues were caused by COVID instead of the vaccine. You'd have to look at infected-but-not-vaccinated patients to have even a hope of answering that question. Of course, the study was essentially designed to elicit that disinformative quote, so I guess that means you're not entirely to blame...?
- russdill 4y agoThe study includes vaccinated and unvaccinated individuals and documents respective risks. It spells this out explicitly in the Results paragraph: "but was lower than the risks after a positive SARS-CoV-2 test before or after vaccination (11.14 [95% CI, 8.64–14.36] and 5.97 [95% CI, 4.54–7.87], respectively)." And more extensively in summary: "First, the risk of myocarditis is substantially higher after SARS-CoV-2 infection in unvaccinated individuals than the increase in risk observed after a first dose of ChAdOx1nCoV-19 vaccine, and a first, second, or booster dose of BNT162b2 vaccine. Second, although the risk of myocarditis with SARS-CoV-2 infection remains after vaccination, it was substantially reduced, suggesting vaccination provides some protection from the cardiovascular consequences of SARS-CoV-2. Third, in contrast with other vaccines, the risk of myocarditis observed 1 to 28 days after a second dose of mRNA-1273 vaccine was higher and similar to the risk after infection. Last, vaccine-associated myocarditis was largely restricted to men younger than 40 years with 1 exception; both younger men and women were at increased risk of myocarditis after a second dose of mRNA-1273." It does so by including "5,934,153 had SARS-CoV-2 infection before or after vaccination."
