(CNN) Coronavirus reinfections are relatively rare, but it's more common for people 65 and older to get infected more than once, according to a study published Wednesday in the Lancet medical journal. In the follow up after six months, the study didn't find any evidence that protection was waning. But a check of the demographics of who was getting infected again showed it was mostly people 65 and older. Of the 11,068 people who tested positive during the first surge, only 72 tested positive again during the second. The older age group had only about 47% protection against repeat infection, compared to younger people who seemed to have about 80% protection from reinfection, the team wrote.
