The Coastal Health District received some doses of the 2009 H1N1 vaccine from the lots that have been voluntarily recalled by vaccine manufacturer Sanofi Pasteur.
There are no safety concerns with the recalled vaccine. After performing routine tests, Sanofi Pasteur notified the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) that the potency in five lots of pediatric pre-filled syringes and one lot of adult pre-filled syringes that had been distributed to providers was later found to have dropped below a pre-specified limit.
CDC and FDA agree that a small decrease in antigen content is unlikely to result in a clinically significant reduction in immune response among persons who have received the vaccine. For this reason, there is no need to revaccinate persons who have received vaccine from these lots.
All children less than 10 years old should get the recommended two doses of H1N1 vaccine approximately a month apart for the optimal immune response. Children under 10 who have only received one dose of vaccine thus far should still receive a second dose of 2009 H1N1 vaccine.
