Re: Can You Get H1N1 More Than Once?
How does she know they had H1N1 twice? I'm not saying she is wrong, I just have not seen any evidence that this happens. Traditionally, one develops immunity through initial infection or immunization and this confers protection against that particular flu virus. Recurrences are usually the result of antigenic drift. I am interested to know if anyone has documented reinfection with H1N1?
