The have been just a few small research that trace at solutions to those key questions, however vital uncertainties have remained. Now, an enormous examine out of Oxford College Hospitals gives a transparent indication that top ranges of antibodies are protecting. However, even with 12,500 individuals, the examine does not remove the uncertainties.
