"Study Finds Switching Arms Boosts Immune Response in OHSU Vaccine Trial"
A study from OHSU suggests that switching arms for multidose vaccines, such as COVID-19 shots, may boost the immune response by up to four times compared to receiving all doses in the same arm. The research found an improved immune response three weeks after the second booster, lasting more than a year, and suggests that this finding could have implications for other vaccines in the future. While the reason for the improvement is not fully understood, researchers believe that switching arms may help the immune system form memories in two locations instead of one.
