Moderna published preliminary data last month that showed its currently authorized 50 microgram booster shot increased the antibodies that block infection from omicron 37 fold. A 100 microgram booster increased those antibodies 83 fold.
Real-world data from the United Kingdom found that Moderna and Pfizer’s two-dose vaccines are only about 10% effective at preventing symptomatic infection from omicron 20 weeks after the second dose.
The same study, published by the U.K. Health Security Agency, found that booster doses are up to 75% effective at preventing symptomatic infection two weeks after receiving the shot.
However, the efficacy of booster shots starts to decline after about 4 weeks, according to the study. Boosters were 55% to 70% effective at preventing infection at weeks 5 to 9, and 40% to 50% effective 10 weeks after receiving the shot.
