Pfizer (NYSE:PFE) today announced that it has started a Phase 1/2 trial of its respiratory syncytial virus (RSV) vaccine candidate in healthy adult volunteers. RSV is a common respiratory virus that affects the lungs and airways, with significant impact on young children and older adults. The highest risk of severe outcome from RSV occurs in the first months of life.

As quoted in the press release:

“A successful RSV vaccine has been an elusive goal for the global health community for decades, but recent scientific achievements have prepared the field to potentially tackle this important pathogen,” said Kathrin Jansen, Ph.D., senior vice president and head of Vaccine Research and Development at Pfizer Inc. “By pursuing a vaccine candidate to help protect both infants and older adults, we hope to make an impact for those most at risk for RSV disease.”

Currently available prophylactic treatments for RSV are limited for use in high risk young children and infants, including very premature infants. If successful, Pfizer’s investigational RSV vaccine could help protect young infants through the immunity created following vaccination of pregnant women. The maternal vaccine candidate is intended to raise RSV neutralizing antibody levels in pregnant women who then pass these protective antibodies to their unborn child and provide immunity during the early months of an infant’s life. Pfizer is also advancing a maternal vaccine candidate against Group B streptococcus (GBS), currently in Phase 1/2 trials.
