Because the H1N1 swine flu vaccine is made the same way as the regular winter flu vaccine, officials don't expect any problems with the new inoculation.
Federal health officials haven't seen any problems so far, Dr. Bruce Gellin, head of the National Vaccine Program Office, told the AP.
On Sunday, ABC News reported that a study published earlier this year that found N95 respirators were better than surgical masks at preventing flu had been retracted. The retraction came on the last day of the Infectious Diseases Society of America annual meeting, in Philadelphia.
After a re-analysis of the study that was prompted by questions from reviewers, the findings were deemed no longer significant, said Holly Seale of the University of New South Wales in Sydney, Australia. The lead author of the study, Raina MacIntyre, also of the University of New South Wales, did not attend the Philadelphia meeting.
