At least 17 public health units including Toronto have decided to now offer the H1N1 flu shot to the general public.

Toronto will begin offering the flu shot to the general public as of today, said Toronto Public Health spokeswoman Susan Sperling.

“Our 10 clinics are fully staffed, and we are now operating seven days a week. Everyone is welcome,” Dr. David McKeown, Toronto’s medical officer of health, said yesterday afternoon.

More than 400,000 doses of vaccine have been distributed to health-care providers in the city and about 85,000 people have been vaccinated at public clinics operated by Toronto Public Health.

Wellington-Dufferin-Guelph Public Health and Oxford County expanded their swine flu shot programs yesterday to include everyone over six months of age who wants the shot.

Health units in York Region, Durham Region, Halton Region and Grey-Bruce said yesterday they will also begin offering the flu shot to the general public today while Peel Region said its health clinics will provide the shot to everyone who wants it, starting tomorrow.

“We have started to receive a steady supply of vaccine from the Ministry of Health and Long-Term Care and I am confident we will be able to meet the public demand for immunization against the H1N1 flu virus,” Dr. Karim Kurji, York Region’s medical officer of health, said in a statement.

Health units for Niagara, Hamilton, Kingston, Simcoe Muskoka, Haldimand-Norfolk, Algoma and the Porcupine Health Unit in Timmins are already offering shots to everyone over six months of age.
