- Pregnant women
- Household contacts and caregivers of children younger than 6 months
- Healthcare and emergency services personnel
- All people from 6 months through 24 years of age
- People aged 25 through 64 years of age who have health conditions that might make them more susceptible to medical complications from influenza
Although not expected, if there is a shortage of the H1N1 vaccine, the first three groups above are still targeted to receive the vaccine, but the last two groups change to:
- Children 6 months through 4 years of age
- Children 5 through 18 years of age who have chronic medical conditions.
For more information about the rationale behind selecting these groups, see the H1N1 vaccination recommendations press release.
The CDC stresses that this vaccine is not a substitute for the seasonal flu vaccine. Both may be administered on the same day.
