COVID-19 vaccination reduces long-term symptoms in teens by 36%, study finds.
A new study of over 1,200 adolescents aged 12 to 17 finds that COVID-19 vaccination reduces the risk of long-term symptoms by 36% compared to unvaccinated peers, with vaccinated youth facing a 20.7% chance of long COVID versus 13.3% among unvaccinated participants.
Conducted during the Omicron wave from February 2022 to November 2024, the research links vaccination within six months before infection to lower risk, even after adjusting for sex and symptom onset.
The findings, from the RECOVER-Pediatrics trial involving 60+ sites, suggest vaccination helps prevent long COVID through multiple pathways.
Meanwhile, a separate analysis of over 400,000 children and teens shows reinfection nearly doubles the risk of long COVID, affecting all age groups and persisting regardless of vaccination or initial illness severity.
