No severe adverse events were reported after inoculation. Based on the results of the evaluation, the experts unanimously agreed that Sinovac’s H1N1 vaccine is applicable to all people from 3 to 60 years old and the vaccination schedule is single shot. The result of the experts evaluation conference will be submitted to SFDA on September 1st, which will be the primary opinion for SFDA to issue the production license.
