yes. the problem was that the main wave of the pandemic hit the u. s. in september 2009. vaccine production was delayed by a lower-than-expected yield of vaccine from the chicken eggs in which vaccine virus is grown. it wasn't until the end of january 2010 that every u. s. resident who wanted the vaccine could get it. by then many people either already had the flu or figured the danger had passed. by midsummer 2010 there was only a trickle of h1n1 infections but deaths and hospitalizations continued among at-risk people who had not been vaccinated. when the vaccine for the 2010-2011 flu season is ready it will include the 2009 h1n1 vaccine as well as a vaccine against two other seasonal flu bugs.
is there a vaccine against the new swine flu virus?
