Another factor contributing to the delay is not having enough manufacturers to actually package the vaccine, according to published reports.
In June, the World Health Organization declared the H1N1 swine flu a pandemic, the first such declaration in 41 years. The declaration was made not because the swine flu is particularly dangerous, but because it had become so widespread. To date, there have been 182,166 cases of infection worldwide and 1,799 deaths, the WHO Web site reported Friday.
In a potential worrisome development, Chilean officials on Friday announced the detection of the H1N1 strain in turkeys in that country, the Associated Press reported. Illness in the birds has been mild, but experts have worried that a more transmissible and virulent strain of human flu could emerge if H1N1 combines with an avian strain.
