Pfizer BioNTech Omicron Booster Delivers Strong Response

Omicron-tuned recordings by Pfizer and rival Moderna Inc have already been given the green light in the United States for both adults and children as young as five years old


US drugmaker Pfizer Inc and its German partner BioNTech SE said their Omicron-matched injection targeting the BA.4/5 subvariants elicited a stronger antibody response in humans than the original injection after one month.

Data in October showed that the vaccine produced a strong response after one week. In a joint statement, the companies said data from about 36 individuals aged 55 or older showed that the booster dose led to a nearly fourfold increase in neutralizing antibody levels against the BA.4/5 variants after one month.

Custom shots of Omicron, made by Pfizer and rival Moderna Inc, have already been given the green light in the United States for both adults and children as young as five.

According to government data, about 26.3 million Americans had received the updated recording by Nov. 2, with about 3.4 million of them in the past week.
