Health District received 3 lots of recalled vaccine

Safety not the issue, re-vaccination is not necessary

December 22, 2009

LAS VEGAS — The Southern Nevada Health District received and distributed approximately 32,000 doses of inhaled vaccine that is part of MedImmune’s voluntary recall. The recall is the result of MedImmune’s ongoing stability testing of its vaccine. There are no concerns regarding safety of the vaccine in question.

Anyone who has received the vaccine does not need to be re-vaccinated because the vaccine in the affected lots is still expected to be effective in stimulating a protective immune response. The doses were well within potency specifications when they were distributed.

The manufacturer has said that the vaccine was delivered in October and early November and administered when the vaccine was fully potent. As is recommended for all 2009 H1N1 vaccine, children under the age of 10 should get the recommended two doses of the vaccine at least 28 days apart for optimal immune response.
