Pfizer and BioNTech announced Tuesday that they have asked the US Food and Drug Administration (FDA) to approve a second booster dose of their covid-19 vaccine for adults over 65 years of age.
The request is based on data gathered in Israel in the midst of a wave of the epidemic caused by the variant strain Omicron of the coronavirus, the companies said in a statement.
According to Pfizer and BioNTech, data from Israel show that “an additional booster dose of mRNA technology vaccine increases immunogenicity and reduces the rates of infections and serious illness “.
That’s why companies have asked the FDA to approve a second booster dose.
Israel was the first country to launch a fourth dose of covid-19 vaccine in early January over the age of 60, and by the end of the same month the program had been extended to all vulnerable adults over the age of 18. groups.
THE fourth dose of vaccine allows three to five times more antibodies to be produced than the third dose, according to the Israeli Ministry of Health.
Some countries – such as Denmark, Spain, Germany and Sweden – already give a fourth dose of the vaccine to specific population groups, such as the elderly and vulnerable groups.
