“Folks with antibodies to pure infections had” a a lot decrease threat … on the order of the identical safety you’d get from an efficient vaccine “of getting the virus once more. It’s extremely, very uncommon to be” re-infected. ” will”.
The second examine, printed Wednesday by the New England Journal of Medication, enrolled greater than 12,500 well being employees at Oxford College hospitals within the UK.
