Pregnant women, children 10 or older and other adults should be given single doses of vaccine against H1N1, the World Health Organization said Friday. An expert panel on immunization recommends additional study of the effect of the vaccine on children between the ages of 6 months and 10, WHO said. The expert group advised that studies in animals have shown the vaccine does not have adverse effects on pregnancy and said any licensed vaccine appears safe for use on pregnant women. The H1N1 flu, commonly known as swine flu, has been most common in children and young adults, WHO said. Pregnant women are far more likely to require hospitalization and intensive care than the population at large, according to WHO quoted by The United Press International (UPI).
