Alternating the arm you receive the COVID-19 vaccination shot in could strengthen the immunity response.
A study published by The Journal of Clinical Investigation last month found that switching arms increases blood antibody levels by up to four times. For people who are immunocompromised or elderly, even a small boost in immunity is significant.
Experts said the report has not been corroborated by other research and only surveyed 947 individuals, but the results look promising. Further study will determine the validity of the findings, which may alter all multidose vaccinations including childhood immunizations against Covid.
