Enough doses of swine flu vaccines for everyone in Wales should begin arriving in the next few weeks. Latest figures show 64 confirmed Welsh cases, but new counting methods mean up to 1m people in Wales could be diagnosed with the illness long term. Up to six million doses would become available, with two per person, and those most at risk would be first in line to receive a jab. Experts will carry out tests and work out how to administer the vaccine. Wales' chief medical officer Dr Tony Jewell said it would be a huge logistical exercise. Dr Jewell said the vaccine would reduce the impact of a second phase of swine flu. It will put us in a good position to modify it. It is an unprecedented situation," he said. So far 64 cases of swine flu in Wales have been confirmed by laboratory testing. Latest figures across Wales reveal that 426 people have gone to their local doctor in the past week with flu-like symptoms. Three were admitted to hospital over the last few days. Health officials said for every 100,000 people there have been 14.2 cases of flu-like illnesses. But Wales is behind other parts of the UK for infection rates. In Scotland the rate is 23.6 cases, while in England it is 51.9 cases. Seven people in Wales with swine flu had to be hospitalised but five have since been discharged. 17 people in the UK have died - all but one of them had underlying health problems. Experts say that for most people the illness is mild and gets better within five to seven days.
