MMR and chicken pox vaccines are effective on extremely premature babies, a study concludes.
US researchers claimed the study wasthe first of its kind to compare the anti-body levels of measles, mumps, rubella and varicella in term and pre-term infants.
The trial included 16 term and 16 pre-term babies, born at around 6.5 months of pregnancy,between May 2002 and May 2005. It found the same number of infants in both groups reached a level of immunity considered protective against the diseases when tested at 15 months.
