Protection From H1N1 Flu Is The Same As From Seasonal Flu – Part 2 of 3
Viral shedding (when the virus replicates and leaves the body), as well as the configuration of actual sickness, were also similar for the two types of flu. The “attack rate” (meaning the balance of people in the entire population who get sick) for H1N1 was higher than that for seasonal flu and the difference was most pronounced among children. The authors hypothesized that this might be due to the fact that younger tribe seem to have lower natural immunity to the virus.
The patients in this study who were given oseltamivir (Tamiflu) did seem to have reduced antibody levels. “This would suggest that maybe oseltamivir may result in a less vigorous immune response than population who are not treated with this drug ,” said Dr John J Treanor, professor of medicine and of microbiology and immunology at the University of Rochester Medical Center.
So “That is very different from studies looking at seasonal flu, where there doesn’t appear to be any accomplish of oseltamivir on antibody response. This should be looked at more closely. It’s potentially important in terms of long-term susceptibility to re-infection. Susceptibility might be different in someone treated with oseltamivir who is not vaccinated. They might have enhanced susceptibility”.
