More than 500,000 people in Taiwan were vaccinated against influenza A(H1N1), commonly known as swine flu, on Saturday, the first day of a national free inoculation program that targets the entire population, a health official said. Most county and city health authorities around the country reported that they had met their goal for the day in terms of the number of people inoculated, Centers for Disease Control Deputy Director-General Chou Jih-haw said. No serious side effects were reported among the people who were vaccinated Saturday, except for 15 cases of people complaining of dizziness after the shots, he said. However, after resting at the immunization stations, all 15 recovered, he added. The national immunization drive will continue Sunday and the rest of the week at all public hospitals around the country, Chou said, urging the public to take advantage of the opportunity to get vaccinated. The comprehensive national H1N1 vaccination program was launched weeks after the first shots were administered on Nov. 1 to people listed in priority groups, such as typhoon victims in shelters, high-risk medical personnel, elementary school students, pre-school children, pregnant women and seriously ill patients, Chou said. The daily average over the past month was 150,000 to 190,000 doses, he added.
