According to Pfizer, the Covid-19 booster triggered an immune response against Omicron in children aged 5 to 11

A booster dose of the Covid-19 vaccine Pfizer and BioNTech SE elicited a strong immune response in children aged 5 to 11, an encouraging sign for youngsters to maintain protection from the virus.

The companies said Thursday that a late-stage study of a booster shot found that the additional injection significantly increased antibody levels against the Omicron variant. The shot also increased the supply of antibodies against the original strain that the vaccines were designed to combat.
