ST. LOUIS (AP) -- People with asthma are being recruited for a national study on whether the swine flu vaccine is as effective for them as the general population.
Washington University School of Medicine in St. Louis is one of seven sites around the country taking part in the study. Participants will be followed to see whether they develop immunity to swine flu or experience side effects.
Dr. Mario Castro, the lead researcher in St. Louis, says he wants to know whether people with asthma will need more than one dose of vaccine to be protected.
Washington University hopes to recruit up to 100 volunteers. Anyone with asthma 12 years or older is eligible.
