To attain most effectiveness, the vaccine requires two doses taken about three weeks aside.

She mentioned there have been 4 circumstances within the vaccine group and none within the placebo group. Whereas the frequency of circumstances was not above that of the overall inhabitants, the FDA advisable additional surveillance if the vaccine is allowed for extra broad use.
