Pfizer: The 3rd injection for children 5-11 years old increases anti-Omicron antibodies 36 times

According to Reuters news agency, the results of serological analysis from 30 children participating in the trial who received the booster vaccine showed a 36-fold increase in the amount of antibodies neutralizing the Omicron variant. Meanwhile, the amount of antibodies that neutralize the original SARS-CoV-2 virus after the 3rd injection increased 6 times.

Pfizer said it plans to apply to the authorities for approval to use the booster shot for this age group in the next few days. In the terminal trial, 140 healthy children aged 5 to 11 years received a booster dose of the vaccine at a dose of 10 micrograms.

According to statistics from the US Centers for Disease Control and Prevention (CDC), only 28% of children aged 5-11 are fully immunized in this country.

Medical experts called Pfizer’s study results “promising,” but noted that the trial was quite small and that other data is still needed to prove how effective the booster shot is.

“Overall, the published results are very optimistic. But it also raises many questions. How long will the protective effect last? Will it resist future variations?” NYU Langone Health Medical Center commented.

Earlier this year, the US Food & Drug Administration (FDA) approved a third dose of the vaccine for children 12 to 15 years old and children 5 to 11 years of age who are immunocompromised.

At the time, the agency said it would consider booster shots for children ages 5 to 11 after a higher proportion of children complete the two shots.
