The CDC says an additional 10 percent to 20 percent of the population should gain flu immunity to protect against a widespread outbreak

The Centers for Disease Control (CDC) yesterday said small children and the elderly were the members of society most vulnerable to A(H1N1) swine flu and urged those who have not received vaccine shots to do so as soon as possible.

A recent study on last year’s flu vaccinations commissioned by the CDC and conducted by Chang Gung Memorial Hospital showed that those who were inoculated were 2.8 times more likely to still have immunity against the virus over those who were not vaccinated.

The hospital said an estimated 30 percent of the population are immunized against A(H1N1) because of a previous infection or vaccination shot, but to be on the safe side against a widespread outbreak, between 40 percent and 50 percent of the population needs to have immunity. The study also showed that of the more than 1,500 people whose blood samples were taken as part of the study, only one out of four children under the age of four had immunity against the strain.
