Stay fit and your COVID injection can work even better
TUESDAY, Oct. 25, 2022 (HealthDay News) — The more often you exercise, the more your COVID-19 vaccination will, a new study suggests.
Fully vaccinated people who recorded high weekly levels of physical activity were almost three times less likely to land in hospital with COVID, compared to those who received the vaccine but did not do so. exercise often, the researchers found.
“The results suggest a possible dose-response, where higher levels of physical activity were associated with greater vaccine efficacy,” said the researchers led by Dr Jon Patricios, of Wits Sport and Health (WiSH) and the School of Clinical Medicine at the University of the Witwatersrand in Johannesburg-Braamfontein, South Africa. The study was published on October 24 in the British Journal of Sports Medicine.

“Public health messaging should encourage physical activity as a simple and cost-effective way to improve vaccine effectiveness in mitigating the risk of serious COVID-19 illness requiring hospitalization,” the researchers added in a press release. .
For the study, researchers analyzed the medical records of nearly 200,000 healthcare workers who belonged to a medical insurance plan with benefits or promotions that required them to wear an activity tracker.
Participants were placed into three different physical activity categories – high, medium or low – based on the average weekly amount they worked out in the two years before the start of the study.
The research team then tracked the results of those who contracted COVID.
High-level athletes who got more than 150 minutes of physical activity each week were 86% less likely to have a case of contracted COVID after their vaccination and land them in hospital, the researchers found.
Similarly, people who averaged 60 to 149 minutes of physical activity per week — the middle category — had a 72% reduced risk of hospitalization from COVID.
But the vaccine was only 60% effective in those who exercised the least, less than 60 minutes per week, the researchers found.
It’s unclear why physical activity might improve COVID vaccination, the researchers wrote.
Exercise can cause the body to produce more antibody in response to the vaccine, or tricking the immune system into being more precise in detecting and attacking the coronavirus, they said.
The United States Centers for Disease Control and Prevention know more about COVID-19 vaccination.
