A new cross-sectional study published in Vaccine of US adults demonstrates that people who received the COVID-19 booster vaccine had 25% lower odds of having long COVID than their unvaccinated counterparts.
The study was based on 8,757 respondents to the 2022 National Health Interview Survey, with data from a weighted sample size of 87,509,670 Americans. Authors used self-reported COVID-19 booster vaccination status and self-reported long-COVID status (defined as having new or persistent symptoms 3 or more months after an initial COVID-19 infection) to calculate odds ratios (ORs) of developing long COVID.
1 in 5 report long COVID
Overall, 2.2% (19,396,656) had not received any COVID-19 vaccine, 17.3% (15,151,843) had received only one dose of the COVID-19 vaccine, 33.3% (29,184,366) had completed the initial series of the COVID-19 vaccine, and 27.2% (23,776,806) received the COVID-19 booster vaccine. Among all respondents, 19.5 % reported experiencing long COVID (17,102,276).
People receiving the COVID-19 booster vaccine had significantly lower adjusted odds of long COVID (OR 0.75, 95 % confidence interval 0.61 to 0.93) compared to unvaccinated people.
"Our findings suggest that ensuring individuals are up-to-date with their COVID-19 vaccinations could be an effective public health strategy for reducing the prevalence of long-COVID," the authors concluded.
