 The recover initiative was launched by the US National Institutes of Health to study the effects of COVID-19 on people who have been infected with the virus for more than four weeks. Using electronic health records from the national COVID cohort collaborative, researchers compared the rate of long COVID among unvaccinated individuals with those who had completed their full vaccine series before being infected. They found that vaccination was strongly associated with lower odds and rates of long COVID diagnoses, even when controlling for age, gender, and medical history. This suggests that vaccines may be able to reduce the severity of long COVID symptoms. This article was authored by M. Daniel Branagh, Robert F. Chu, Alexander J. Price, and others.
