Recent research suggests that the choice of arm for the second dose of the
Covid-19 vaccine may influence the immune response. The study indicates
that individuals who received their second vaccine dose in their
non-dominant arm exhibited a more robust immune response than those who
received it in their dominant arm. While both arms led to effective vaccine
response, this finding highlights the potential impact of injection sites
on immune reactions. Scientists emphasize that the overall efficacy of
vaccination remains high regardless of arm choice, but the study sheds
light on an interesting aspect of vaccine administration.
