New COVID-19 boosters are demonstrating a “substantially higher immune response” against the omicron variant, according to Pfizer and BioNTech.
Pfizer and BioNTech looked at how much protection is offered one month after vaccination. They're following 900 participants in a study.
The new boosters increased participants' COVID-19 antibodies by 9.5 times for adults ages 18-55. The companies said that adults over age 55 saw a 13.2 times jump in antibodies against the omicron variant.As we head into the holiday season, we hope these updated data will encourage people to seek out a COVID-19 bivalent booster as soon as they are eligible in order to maintain high levels of protection against the widely circulating Omicron BA.4 and BA.
Pfizer's data comes after two smaller university studies last week showed a more insignificant increase in antibodies. Federal officials, however, noted the size of the studies were small.
