CDC Novel H1N1 Vaccination Planning Q&A
2009 H1N1 Influenza Vaccine and Pregnant Women
1.Q. How much Thimerosal-free vaccine will be available?
A. It is anticipated that enough thimerosal-free vaccine in pre-loaded syringes will be available for young children and pregnant women.
2.Q.Do those that have been previously vaccinated against the 1976 swine influenza need to get vaccinated against the 2009 H1N1 influenza?
A.The 1976 swine flu virus and the 2009 H1N1 virus are different enough that its unlikely a person vaccinated in 1976 will have full protection from the 2009 H1N1. People vaccinated in 1976 should still be given the 2009 H1N1 vaccine.
