New York City is changing its flu vaccine, now that health officials say the H1N1 flu pandemic is over.

The City's Health Department says it will order only one vaccine for both the regular flu and H1N1/swine flu this fall.

The news comes after the World Health Organization declared the virus to be in a post-pandemic phase, as cases of the virus have significantly dropped off.

DOH officials say they do not have a total count of New York City's H1N1 cases.

At least 800,000 New Yorkers were vaccinated against H1N1 last year.
