So you think you've had swine flu and don't need to get a vaccination. A local doctor says think again.
Dr. Mudassar Chaudry, an infectious disease expert with Lewis Gale Medical Center, says most H1N1 cases are just suspected and have not been confirmed.
Chaudry says even if a lab test confirms you do indeed have swine flu, that doesn't mean you can't get it again.
"If truly it was swine flu, still the virus can mutate in the same season.", says Chaudry. "You can still become ill again with a slightly different strain of the same virus."
Chaudry says the virus can even mutate to the point it becomes resistant to anti-viral drugs like Tamiflu.
