NOTICE: On December 22, there was a non-safety related voluntary recall of certain lots of MedImmune's H1N1 nasal spray vaccine due to their slightly decreasing potency. The Anne Arundel County Department of Health administered approximately 2,400 doses of the identified MedImmune nasal spray vaccine at H1N1 clinics in October and during the first two weeks in November. During this October/November time period, the vaccine fully met potency requirements, and there is no public health concern. See Non-Safety Related MedImmune Vaccine Recall

Earlier in December, there was a non-safety related voluntary recall of certain lots of Sanofi Pasteur H1N1 pediatric (for 6-35 month olds) thimerosal-free vaccine in pre-filled syringes. However, the Anne Arundel County Department of Health did not receive or administer any of the recalled vaccine at any of its H1N1 vaccine clinics. Non-Safety Related Vaccine Recall

As the Department of Health receives more H1N1 flu vaccine, more clinics will be scheduled for the general population. Also, some private providers and pharmacies have the H1N1 flu vaccine. See Find a Flu Shot.

People who are pregnant and people with chronic health disorders or with compromised immune systems can only get the injectable flu vaccine.

Children who are currently 9 years old and younger should receive a second dose of the H1N1 vaccine. The CDC recommends that the doses be separated by 28 or more days, however a second dose given at a minimum of 21 days after the first dose is considered valid.
