According to figures released by Statistics Canada on Thursday, in the previous winter around 6 out of 10 children aged 12 didn’t receive the H1N1 flu vaccination.

The statistics showed that around 41% people in Canada, excluding the territories, got the flu shots, that is, around 11.6 million people and around 60% didn't go for vaccination.

The pandemic vaccine was given to two-thirds of health-care workers and around 55% with chronic conditions also received the vaccination. The survey found that 74% people felt that they ‘did not think it was necessary’.

People who were surveyed between January and April this year said that they have still not gone for vaccination. Many people cited the reason ‘fear’ for not going for vaccination.

For Canadian Community Health Survey, as many as 20,000 Canadians were questioned.

On the other hand, in the United States, it is estimated that around two-thirds may already be immune to H1N1 swine flu.

Experts say that unless the flu virus mutates, around 59% people in America can't get H1N1 swine flu.

The top researchers at the National Institutes of Health believe that increased rate of vaccination in this flu season among children and young adults may lead to the extinction of the pandemic bug.
