Third dose Covid vaccine, Viola: “At the moment there is no evidence that it is needed”

WILL a third dose of the vaccine be needed? The government of Israel announced two weeks ago that it would begin offering a third dose of Pfizer vaccine to adults with immunodeficiencies, reserving the right to consider making the third dose available to others. Pfizer, which notes that Israeli health ministry data shows how the vaccine‘s effectiveness in preventing infection and symptoms declined in the six months after vaccination, although effectiveness in preventing hospitalization remains high, announced which is about to publish data on the effectiveness of the third dose and will ask the American FDA for emergency authorization in August.
