Pfizer and BioNTech announced Tuesday that they had required the US Drug Administration (FDA) to approve an additional booster dose of the COVID-19 vaccine for people over the age of 65.
For their request, they were based on Israeli data and analyzed when the omicron variant was widely circulated, the company said in a statement.
According to Pfizer and BioNTech, the data show that “an additional booster dose of the messenger RNA vaccine increases immunogenicity” (the ability to induce an immune response) and “reduces the rate of identified infections and serious illnesses.”
Therefore, the company asked the FDA for approval for emergency use.
