"Mexican President's Third COVID Infection Raises Questions About Reinfection"

Mexican President Andres Manuel Lopez Obrador has tested positive for COVID-19 for the third time, highlighting the risk of reinfection. Studies suggest that most Americans have been infected with COVID at least once, but a growing number have been infected multiple times. While being fully vaccinated and getting the booster shot can lower the risk of reinfection, studies have shown that immunity does wane over time. The risk of reinfection is highest for those who are vulnerable to serious complications from COVID. The role of variants is also important, as a new variant could change how likely reinfection is.
