Jab message in swine flu return
Medical experts warned swine flu will be the worst strain of the virus this winter as the seasonal vaccination campaign began today.
The Health Service Executive (HSE) urged at-risk groups such as mothers-to-be and older people to get the single injection to protect against three types of the illness.
Dr Brenda Corcoran, of the HSE national immunisation office, warned swine flu would be the dominant strain over the next few months.
"The flu vaccine cannot give you the flu as it does not contain any live flu virus," she said.
One jab will protect against swine flu, which was infecting 7,000 people a week this time last year, and two other types of the virus.
