Adults and women are at higher risk for covid recurrence

"The mechanisms underlying certain factors associated with reinfection (e.g., excess risk in women) need further investigation," Dr. Chandima Jeevandara said.

Meanwhile, the research has demonstrated a considerable rise of anti-SARS-CoV-2 antibody levels in COVID-19 survivors after booster vaccination, which will likely lower the risk for reinfection further than relying on natural immunity alone.
