This review highlights key psychological and behavioral factors that can
influence the immune system's response to a vaccine. The results
generalize across a wide variety of vaccines, and therefore will likely
be relevant to the SARS-COV-2 vaccine. Although the SARS-COV-2 vaccine
candidates are highly efficacious, these psychological and behavioral
factors can impact how long it takes to develop protective immunity as
well as how long the protective immunity lasts. Importantly, even
short-term psychological and behavioral interventions can boost the
immune system's response to vaccination.
