Unexpectedly, five of the other six infected donors experienced low-level anti-HBs or a rapid anamnestic response, attributable to the receipt of HBV vaccine 7 to 27 years earlier. The five vaccinated donors got a brief, transient span of infection with no proof disease and very absent or low expression of HBsAg. Viremia, that was of short duration, ranged from 11 to 86 IU per milliliter at donation. Four of the five vaccinated donors who have been followed were also positive for IgM anti-HBc, confirming acute infection. Smaller studies in the United States have typically shown around one HBV-contaminated donor per 600,000 donations screened.15 In countries where HBV infection is endemic, rates are higher.10,19 The three acute infections among nonvaccinated donors were of subgenotype A2, which is probably the most frequent genotype in the United States and is the parent strain of the HBV vaccine.We have up to now 30 situations [of H1N1 flu] which have been laboratory confirmed, said Naresh Dayal, medical secretary of India.
