A recent study led by researchers at the Yale School of Public Health has indicated that regular COVID-19 boosters may be key in reducing infection. The study found that receiving a booster shot once or twice a year significantly reduces the probability of COVID-19 infection. Despite hopes that the initial COVID-19 vaccination series would be effective at preventing long term infection, short-term studies involving SARS-CoV-2 neutralizing antibodies have indicated that antibody protection against infection wanes significantly post-vaccination and even post-booster. Researchers involved in the study include Hayley Hassler, a Ph.D. student in Interdisciplinary Graduate Program in Quantitative Biosciences (QBioS) at Georgia Tech.
