AUGUSTA, Maine — Gov. John Baldacci is encouraging all Mainers to receive vaccinations against the seasonal flu and H1N1, or swine flu, in the weeks ahead.

In his weekly radio address, the governor says a fast-spreading flu has the potential to shut down schools and businesses, close government offices and leave vulnerable people without the support and services they depend upon. Baldacci says that could result in economic disruption and tragic consequences for some.

Neither the seasonal flu nor the H1N1 flu vaccine is mandatory. But Baldacci says that the more people who are inoculated, the better chance of slowing the disease.

Maine has just begun to receive doses of the seasonal flu vaccine, and Baldacci says the swine flu vaccine will likely be available in October.
