  • The H1N1 virus that caused that pandemic is now a regular human flu virus and continues to circulate seasonally worldwide.

2009 H1N1 Flu Vaccine

Vaccines to protect against 2009 H1N1 are widely available. CDC is encouraging everyone to get vaccinated against 2009 H1N1. Those who have been patiently waiting to receive the 2009 H1N1 vaccine are now encouraged to get vaccinated. Due to early availability of, and high demand for, seasonal flu vaccine, remaining supplies of seasonal vaccine are limited. CDC continues to encourage those at highest risk from flu complications to seek seasonal flu vaccine and receive 2009 H1N1 vaccine, as recommended.
