CBS News: People who just got the Johnson & Johnson vaccine are worried. What should they look out for?
Dr. Anthony Fauci: Well, it depends on when they got it. It appears that this adverse event occurs between six days and 13 days. So if you’ve had it a month or two ago, I think you really don’t need to worry about anything. If you are in the time frame of within a week or two of having gotten vaccinated, remember one thing: This is a very rare event. It’s less than one in a million. Having said that, you still wanna be alert to some symptoms, such as severe headache, some difficulty in movement, or some chest discomfort and difficulty breathing.
