Two studies in The Journal of Infectious Diseases look at virus shedding in the stool in people infected with AIDS and at the use of vaccines with killed virus.
Virus shedding could be significant in countries with large numbers of HIV-infected people, including many African countries. A team from the Centers for Disease Control and Prevention and colleagues from the Cote d'Ivoire examined virus shedding in HIV-infected people given oral polio vaccine, which contains attenuated live virus. The researchers found that only 1 percent of those with HIV experience prolonged virus shedding, suggesting that the chances of polio reintroduction are minimal.
Another study by doctors from the U.S. Food and Drug Administration and other institutions looked at inactivated polio vaccine. They concluded that it offers partial protection and may do a better job with improvements.
