Vaccine against influenza administered to women during pregnancy keeps baby from hospital

Babies born to women who were born on influenza vaccine during pregnancy was born at a rate less than the cost of hospitalization of infants not vaccinated for mothers, according to preliminary results from an ongoing study by researchers at Yale School of Medicine. The team presented the study, 29th October at the 47th Annual Meeting of the Infectious Diseases Society of America in Philadelphia. Influenza is a major cause of severe respiratory illness among pregnant women and infants hospital. Although vaccination against influenza for all pregnant women and children, no vaccine is recommended for infants under six months of approval. Prevention strategies for this age group are the general control of infections and vaccinations, which are in close contact with them. Few studies have examined the effectiveness of the vaccine against influenza during pregnancy.

By Marietta Vázquez, MD, assistant professor of pediatrics at the Yale School of Medicine, this new study, SLE is a case-control study on the effectiveness of vaccination of pregnant women to hospital, to prevent their children. For nine flu seasons from 2000 to 2009, identified Vázquez and colleagues and more than 350 mothers and children from 0 to 12 months, which is at Yale-New Haven Hospital, the hospital followed. They compared 157 children in the hospital before and 230 of avian influenza not infants, matched for age and length of hospitalization. The team interviewed parents to determine risk factors for influenza and reviewed medical records of children and their mothers to determine rates of immunization with the vaccine against influenza.

"We found that immunization of mothers during pregnancy, 80 percent effective in preventing hospitalization due to influenza in infants during the first years of life and 89 percent effective in preventing hospitalization for children under six months, "said Vazquez.

"These results are not only positive effects on infant health at risk, but also very profitable because it is a protective vaccine for two people," said Vazquez. "The results may also help establish public health, awareness of the importance of influenza vaccination during pregnancy, and even help to overcome barriers to vaccination. "
