A swine flu vaccine to be used in the UK has been approved by European regulators.
The European Medicines Agency has recommended to the European Commission that Pandemrix, made by GlaxoSmithKline (GSK), be granted a licence for use across Europe, including the UK.
Another vaccine intended for use in the UK, made by Baxter, is still being considered by the European Medicines Agency.
The European Commission will probably rubber-stamp the decision on the GSK vaccine in the next few weeks.
GSK has not yet delivered stocks of its vaccine to the Government, a spokesman for the Department of Health said.
Some stocks of the Baxter vaccine have already arrived.
It is not yet clear when the swine flu vaccine will be available to patients in the UK.
The Government had been hoping to start vaccinating people in high-risk groups, such as those with asthma and diabetes, and health workers, in October.
A spokesman for the Department of Health said: "We are pleased that the European regulator has recommended that the GSK vaccine should be granted a licence by the European Commission.
"This is a positive step towards getting full licences for vaccine to protect the public. The European Commission must now consider the recommendations and we hope for their decision as quickly as possible."
