Just 19% take up swine flu jab

[tetano]

Just 19 per cent of Australians took up the offer of a free vaccine to protect them against the swine flu.

There was enough of the vaccine to inoculate the entire population against the a(H1N1) virus.

But it is estimated about only four million people took up the offer

This was "much lower than the implied 50 per cent target required to contain community transmission", according to a paper published online by the Medical Journal of Australia (MJA) on Monday.

"Contributory factors may include the public's and vaccine providers' perceptions that pandemic influenza causes mild illness (or) negative media reports about vaccine safety and multi-dose vials."

Another factor could be the inoculation campaign fell outside of the pre-winter period when people typically turned their minds to getting a flu jab.

WA-based researchers assessed the number of pandemic influenza vaccinations administered from late September 2009 to late January this year.

It determined the vaccination rate in WA was "comparable to the national estimate of 19 per cent".

The researchers said the Australian government initially ordered 21 million doses of the vaccine, when it was thought two doses would be needed per person to provide complete protection.

However, testing showed one dose was sufficient and "thus, there was sufficient vaccine for the entire population and all Australians aged ten years and older were encouraged to be vaccinated."

The vaccine's roll out in WA "did not reach levels considered sufficient to interrupt community transmission", the paper said.

Another WA based study also published online by the MJA on Monday found pregnant women - who were identified as at particular risk of serious illness, even death, from the swine flu - also had a low take-up of the vaccine.

A study of almost 480 pregnant women who arrived at a Perth-based clinic in January this year found just 33 (6.9 per cent) had been vaccinated.

"The Australian Chief Medical Officer wrote to general practitioners in November 2009 emphasising the increased risk to pregnant women of severe pandemic influenza and the suitability of the H1N1-specific vaccine for use in pregnancy," the paper states.

It said uptake of the vaccine was "poor" and the reason given by more than 60 per cent of the women was "safety concerns".

While 19 per cent of the population were administered the free a(H1N1) vaccine, more would have gone on to receive a protective jab against the swine flu.

The swine flu vaccine was incorporated into the trivalent flu jab distributed through workplaces early this year, and which protects against the three major flu strains forecast to hit during winter.

Re: Just 19% take up swine flu jab

The Australian Institute of Health and Welfare (AIHW) has put the total number of vaccinated Australians at the end of February at about 3.9 million, or 18 per cent of the population.

"Of those who had not been vaccinated, more than one in four adults intended to get vaccinated before this winter,' said AIHW director Dr Penny Allbon.

However, she said, more than half of all adult Australians (56 per cent) had not been vaccinated and said they were not intending to get vaccinated before the 2010 flu season arrived.

The main reasons reported for not getting vaccinated included a perception that swine flu was not a serious risk to their own health (26.7 per cent), the vaccine had problems (15.7 per cent), vaccination was not a priority for them (10.9 per cent) and the threat of swine flu had already passed (11.6 per cent).

The vaccine offering protection against the A(H1N1) virus, swine flu, was available free of charge in Australia from the end of September last year.

The percentage of adults - those 18 years and over - vaccinated was 21 per cent.

Some of the reasons why people wanted to get vaccinated included the seriousness of swine flu (25 per cent), doctor's advice (17 per cent), employment-related reasons (14 per cent) and belonging to an "at risk" group (11 per cent).

Tasmanians were the most willing to get the free vaccination while those in WA were the least likely.

"From the survey results, there appears to be some state variation in vaccination uptake," Dr Allbon said.

"Tasmania had the highest vaccination uptake at 23.5 per cent, while Western Australia had the lowest, at 15.0 per cent."

When the swine flu vaccine was released it was approved for those aged 10 years and older, and from December it was approved for children aged six months to nine years.

While all Australians were encouraged to get vaccinated, it was strongly recommended for pregnant women, parents and guardians of infants, people with underlying chronic conditions, the severely obese, indigenous Australians and health and community care workers.

"Of these "at risk" groups, significantly higher vaccination uptake than the general population was seen among people with underlying chronic conditions (34.7 per cent) and health and community care workers (29.5 per cent)," Dr Allbon said.

Australia has recorded five swine flu-related deaths so far this year, according to reports to the National Notifiable Diseases Surveillance System.

The deaths occurred in late May, July and August with a median age of 49 years.

All cases were reported as having underlying risk factors.
