Flawed analysis by Peter McCullough and others used to promote baseless claim that brain blood clots “112,000% more likely” after COVID-19 vaccine than flu vaccine
Since 2021, certain COVID-19 vaccines, specifically the viral vector COVID-19 vaccines, have been linked to a rare blood clotting problem known as thrombosis with thrombocytopenia syndrome. But COVID-19 mRNA vaccines aren’t associated with the same risk. COVID-19 vaccines are highly effective at reducing the risk of severe disease and death. Getting COVID-19 is associated with a much greater risk of blood clots than getting the vaccine. On balance, the vaccines’ benefits outweigh their risks.
