To do that after the preliminary two doses.
“We actually have very little scientific data to suggest that a fourth dose will provide a substantial degree of protection against serious illness and hospitalization,” he instructed CNBC. “So this was a recommendation based on expert opinion, not a recommendation based on strong data as we would ideally like to do in clinical medicine. We use expert opinion when We don’t have evidence, and we do that all the time. Clinical medicine.”
Health officers in different nations are at the moment divided as as to whether a fourth dose of COVID vaccines shall be essential.
