David Cameron was forced to reject that spending cuts had made Britain vulnerable to swine flu as he warned that the country is facing ‘significant outbreaks’ of flu for years.

Prime Minister argued that lessons must be learned from the vaccine shortage that have seen GP surgeries turning away vulnerable people looking for the flu shot in recent days.

The matter was raised as Labour blamed the association for putting pregnant women at risk by failing to promote the flu jabs.

Mr. Cameron went on: "We need to look at the way we order vaccinations and whether more needs to be done."

In previous years, under the guidance from the Department of Health, they ordered vaccines for more than six months in advance. This gives the manufacturers enough time to make sufficient vaccines, which has a six months extra time.

However, the death toll for flu outbreak has reached to 50 since October. Most of the deaths were due to swine flu, while the dominant stain of influenza is circulating in surroundings.

Last week the government announced it was being forced to raid last year’s stokes of swine flu jab to over come the shortages in the vaccination program.
