The Government admitted some parts of the country were suffering shortages of flu vaccines as it prepared to reveal the latest death toll from the winter outbreak.
Ministers have urged flu vaccine manufacturers to check their European stocks, which could be brought in to help bolster supplies across the UK.
The Government will publish new figures later today on the number of people who have died from the virus. So far, 39 people have succumbed since the start of this season's outbreak in October.
Suppliers have been asked to contact their factories in Europe for a count of UK-licensed vaccines after the Government admitted it was considering bringing in supplies.
There is no central stockpile of seasonal flu vaccines, which are ordered every year by GPs and delivered to surgeries.
After reports of patients being unable to get jabs from their GP the Department of Health (DoH) issued a statement insisting there was "no national shortage" but admitted some areas were experiencing "local
A spokeswoman for the Scottish Government said there were "no supply issues" in Scotland, with more than a million doses distributed to GP surgeries and pharmacies, with an "additional stockpile" available if needed.
Sanofi Pasteur MSD, which manufactures some of the jabs, said it had
been asked by the DoH about the number of available doses in the UK and the number of UK-licensed doses which could be brought into the UK.
It has also been asked for a count of the number of other (non-UK labelled) doses it has in Europe, which could be brought in subject to regulatory issues.
Millions of doses of seasonal flu vaccine are ordered by GPs in England every year.
According to the UK Vaccine Industry Group, 14.7 million doses have been delivered across the UK, with 4% of those stocks going to private companies.
The DoH hopes local supply issues can be resolved by surgeries with surplus vaccine offering it to others suffering shortages.
A spokesman said: "We are aware of some reports of supply issues in some areas.
"We are working with the NHS at the local level to ensure available supplies of surplus vaccine are moved to where there is a need for them."
Shadow health secretary John Healey said: "This action is better late than never but will only add to the confusion over the Government's handling of the swine flu outbreak.
"The take-up of the flu jab has been down on last year, yet there are still reports of GPs running out of vaccines."
Of the 39 deaths so far this flu season, 36 people had swine flu and another three had a separate strain, flu type B, according to figures released on New Year's Eve.
All except one case were under 65 years of age and four were under the age of five.
More than 700 people were also in critical care (intensive care and high dependency beds) at the last count.
The latest figures come as the Government urges people in at-risk groups, including pregnant women, to get their flu jab.
Parents have also been urged to get their children vaccinated against flu if they fall into risky groups, such as those with asthma or kidney disease.the Government prepared to publish new figures later today on the number of people who have died from flu. So far, 39 people have died with confirmed flu since the start of this season's outbreak in October.
In a statement on its website the Royal College of General Practitioners (RCGP) urged GPs to continue efforts to offer vaccination to all at-risk patients.
It said: "There have been some local reports of vaccine shortages, but the RCGP is not aware of a major national issue.
"Colleagues are encouraged to share resources to liaise with local colleagues, or the PCT, and explore opportunities to make vaccines available in places where it is needed most."
Television GP Dr Rosemary Leonard yesterday told the BBC she had experienced difficulties at her practice and had 40 people waiting for the vaccine.
She said: "There is a problem now with the vaccine supply. GPs order in their vaccines earlier in the year, we order in enough generally for our at-risk groups. In the beginning of December there was loads and loads of vaccine. Now unfortunately there has been a rush on the vaccine and my surgery ran out yesterday."
