Scientists around the world have been working around the clock to learn more about this variant. Available research indicates that existing vaccines, which are among the greatest public health achievements globally, will continue to protect against the most severe forms of the disease, all the more reason to get booster doses. The first preliminary reports on protection against Omicron are data to be interpreted as the first available evidence. Nor are their findings definitive, they do not have enough information yet. However, here we tell you what is the efficacy, according to the pharmaceutical companies. Pfizer one of the most widely administered vaccines in the world against covid-19 is Pfizer.
