Britain and France have received their first batches of swine flu vaccine, officials said Thursday, as governments began to arm themselves against a second wave of the pandemic in the northern winter.
The World Health Organization has been warning governments for months to brace for a resurgence of the A(H1N1) virus when the cold season hits the northern hemisphere.
The doses to combat the pandemic arrived as millions of schoolchildren prepared to return to school in the next two weeks, with concerns that the virus could spread easily between classrooms.
In South Korea, the education ministry announced that all elementary and secondary schoolchildren will have their temperature checked daily to combat the spread of H1N1 when they return to school next week.
The recent discovery of an outbreak in Chilean turkey farms also raised concerns that swine flu could combine with avian influenza and become a more dangerous virus, a UN agency said. It is the first case of H1N1 among birds.
British and French health officials said the H1N1 vaccine should win licensing approval for distribution in their countries by October.
Britain's Department of Health said it received a first batch of 100,000 doses of swine flu vaccine, while France announced the arrival of a "limited quantity" of shots. Belgium said it would get its first doses next month.
A British health department spokeswoman said the vaccine was delivered by US pharmaceutical company Baxter and that it could be approved for public distribution by early October "if everything is fairly straightforward".
