Summary: Health behaviors and emotional stressors can alter the body’s ability to develop an immune response to vaccines, including potentially the new COVID-19 vaccines. Simple interventions, including exercising and getting a good night’s sleep in the 24 hours before vaccination, may maximize the vaccine’s initial effectiveness.
Decades of research show that depression, stress, loneliness, and poor health behaviors can weaken the body’s immune system and lower the effectiveness of certain vaccines. A new report accepted for publication in
Perspectives on Psychological Science suggests that the same may be true for the new COVID-19 vaccines that are in development and the early stages of global distribution. Fortunately, it may be possible to reduce these negative effects with simple steps like exercise and sleep.
COVID-19 vaccine creates incentive to improve our health
Previous research suggests stress, depression, inactivity could interfere with immune response
While we wait for our turn to get vaccinated against SARS-CoV-2, we could – and probably should – use the time to make sure we bring our healthiest emotional and physical selves to the treatment, a new review of previous research suggests.
Ohio State University researchers reviewed 49 vaccine studies in humans dating back 30 years that document how stress, depression and poor health behaviors can negatively affect the body’s immune response to vaccination, and how improving health factors can enhance that response.
The impaired immune responses tended to fall into three categories – interference with the development of antibodies against the pathogen, more rapid erosion of antibody protection that does develop, or intensification of vaccination’s side effects.
