Much has been said in recent months about the need for a third dose of the vaccine against covid-14 so that the antibody rate is not reduced. With this, studies have been carried out to prove the effectiveness of the measure. One of them, carried out in Israel, found that the booster dose actually further reduces the risk of developing the severe form of the disease.
