CDC: COVID-19 vaccines lower hospitalization risk if reinfectedÂ
In a study of adults previously infected with COVID-19, the Pfizer and Moderna COVID-19 vaccines offered additional protection against reinfection leading to hospitalization, the Centers for Disease Control and Prevention yesterday. Those who had completed a primary vaccine course and booster dose had the highest level of protection. A booster dose offered similar protection against hospitalization (60%-70%) after reinfection whether the delta or omicron variant predominated, while a first or second vaccine dose offered 50%-60% protection during the delta variant period and 35% during omicron.
