BURLINGTON – The Vermont Department of Health was notified yesterday of a voluntary, non-safety related recall of certain lots of 2009 H1N1 nasal spray vaccine. A slight decrease in the vaccine potency was reported by the manufacturer (MedImmune) to the Centers for Disease Control and Prevention (CDC).

The vaccine passed pre-release testing standards, but some of the vaccine, due to shelf-life concerns, may have slightly decreased in potency over time

“This is not a safety concern and the doses provide adequate protection, so anyone who has already been vaccinated won’t need to take any corrective action,” said Health Commissioner Wendy Davis, MD.

Children and adults aged 10 years and older who received the vaccine do not need any further doses. All children younger than 10 years old should get the recommended two doses of 2009 H1N1 vaccine approximately a month apart. Children younger than 10 years old who have only received one dose of vaccine should still receive a second dose of 2009 H1N1 vaccine.

Children are less likely in Vermont than adults to have received a nasal spray dose, since all of the 397 school vaccine clinics held to date offered shots rather than the spray.

A Question & Answer guide to this recall is available online from the CDC:

Vermont announced on Dec. 22 that it is now offering vaccine to anyone 6 months and older who wants it.
