WHO IS AT HIGHEST RISK OF THOSE SIDE EFFECTS?

“The side effect appears to be most common after the second dose of Pfizer or Moderna vaccine, and is particularly high in young males. It should be noted that even in this group, it still is a rare side effect. If we vaccinated an MCG full of men under 30 (about 100,000), we might see three or four cases after the second dose. In other groups, the risk is even lower – we would be unlikely to see one case in 100,000 vaccinated women,” Prof Cheng says.
