The risk of long COVID was 36% lower in adolescents vaccinated within 6 months before their first infection than in their unvaccinated peers, suggests an analysis of US Researching COVID to Enhance Recovery (RECOVER) trial data published late last week in Vaccine.

The study, led by Massachusetts General Hospital researchers, involved 724 adolescents aged 12 to 17 years who were vaccinated against COVID-19 within the previous 6 months and 507 unvaccinated youth matched on sex, symptom onset, and enrollment date.
