Hyderabad, Sept. 14 Has the virus A (H1N1) influenza undergone mutation? Health officials in Andhra Pradesh have said that they have observed a second strain of the influenza, a virulent one than the first strain noticed in the first bout of the influenza in May.

This, perhaps, casts doubt on the efficacy of the upcoming vaccine which is likely to hit the markets in a couple of months from now.

Mr L.V. Subrahmanyam, Principal Secretary (Health), told a press conference here that the vaccine might be useful for one season. “The protection is not life-long,” he said. “We have seen two strains so far. The one that infected people during May-Septemberwas one H1N1 strain. While the vaccine might be useful for the first strain, the second one that is prevalent now is found to be virulent,” he said.
