We've got lots of children in the hospital but already very sick, the last thing we need is for them to get flu. Also to protect themselves, we don't want our staff to go sick. But we also want to protect their homes as well,we wanna make sure that they some flu in the hospital and take it home to their families.

Offical figures show that of 133 hospital trusts, just 40 vaccinated 75% of staff, the target set by the Department of Health. Kings College Hospital in London had the lowest rate with less than 30% of front line staff vaccinated. Great Ormond Street children's hospital, the Royal Marson Cancer Hospital and the Royal Brompton Heart Hospital also have low rates and they treat particularly vulnerable patients. I specialist says staff's refusal to vaccine are being irresponsible.

I think they certainly have naievity in the sense that they don't perceive they are protecting colleagues or protecting patients and feel that they are not vulnerable themselves to flu why should they have a injection of vaccine.

Once the virus gets on board, it can quickly spread. Here at the L Royal in F, just last month, six children on the high dependency unit came down with swine flu, 3 had to be isolated. The source of the infection was never traced. And it could be a visitor, but barely half of the staff had been vaccinated. Failure to hit the vaccination target could prove costly to hospitals. The Department of Health told Sky News that only in exceptional circumstances will there be considered for a share of a 250 million pound windfall to help the ANE pressure next winter. It added uptake is currently at its highest level ever, however it is clear there is more to do. Expect more videos next winter, but with growing frustration, the health worker needs so much convincing to protect the health of patients.
