"
People who had more than one COVID-19 infection were three times more likely to be hospitalized and twice as likely to die than those who only had one infection. Those with multiple infections were also more vulnerable to other dangerous conditions; they were 3.5 times more likely to develop lung problems,
3 times more likely to have heart conditions, and 1.6 times more likely to have brain changes requiring care than people who had only had COVID-19 once."

might be more likely to have ischemic strokes within the first three weeks after their shots."
