Study Finds Alternating Arms for Vaccinations Boosts Immunity

A recent study reveals that receiving booster shots in the opposite arm can significantly enhance the immune response, with implications for future vaccination strategies.

A new study suggests alternating arms for multidose vaccinations, like COVID-19 vaccines, may significantly improve the immune response.
Researchers observed up to a four-fold increase in antibody levels when participants received their booster shot in the opposite arm.
The study, conducted by Oregon Health & Science University, involved nearly 1,000 participants and tracked their immune responses over 14 months.
The enhanced immune response was noted against both the original coronavirus strain and the Omicron variant.
Further research is needed to confirm these findings and explore implications for other multidose vaccines and clinical recommendations.
