Starting Thursday, anyone in Ontario over the age of six months will be able to get vaccinated against the H1N1 virus, the province says.

Health Minister Deb Matthews made the announcement at news conference held Wednesday in Toronto -- the same day Toronto Public Health began immunizing all members of the public.

"We're opening up our immunization program to everyone in Ontario aged six months and over, no matter their age, no matter their health condition. It's a big step forward in our vaccination program, and one we're taking earlier than expected," she said.

"Now is the time to get immunized," added Dr. Arlene King, the province's chief medical officer of health.

Reporters noted that even last week, many thought the general public might not be getting immunized for weeks.

King said the province finally has some stability of supply. So far, 2.5 million doses have been administered to the priority groups and there are 1.5 million doses in reserve, with 500,000 to one million expected next week.

Because public health workers have put in a tremendous effort, there's now enough capacity to offer vaccination to everyone, Matthews said.

"Now, when I say accommodate everyone, I don't mean everyone all at once," Matthews. "For the first few days at least, there will be lines at our clinics. Some people will have to wait, so I would encourage you not to rush."

People can get the shot when it fits into their schedule, and Matthews suggested people review vaccination options other than the public clinics.

For example, more than 1,000 doctors in Toronto offer the vaccine, she said, adding, "Over time, we will have enough vaccine for everyone who wants the shot."

Matthews thanked those who waited their turn while those deemed to be most vulnerable could get vaccinated. "You let those who needed the shot go first," she said.

King said since April, there have been 76 deaths in the province where the deceased person was confirmed to have contracted the virus.

There are 213 people currently in hospital, with 82 of those in intensive care.

"H1N1 activity continues to be high in many areas of the province, and is more than double what we've seen in past flu seasons," she said.

As a result, people continue to show up at emergency wards and flu assessment clinics with fever and respiratory illness, King said.

While this policy is now officially province-wide, some health units had already commenced widespread immunization if they had the capacity and vaccine supply, she acknowledged.
