Seniors who were fully vaccinated with the Pfizer or Moderna Covid-19 vaccines were found to be highly protected against hospitalisation compared to unvaccinated adults of the same age, the latest data reveals.
This week, the Centers for Disease Control and Prevention (CDC) released the small study, which involved 417 patients aged 65 or older.
While the vaccine showed 94% effectiveness against Covid-29-related hospitalisation, this dropped to 64% in participants who only received a single dose less than two weeks earlier.
