The U.S. approved the first vaccine for RSV on Wednesday, shots to protect older adults against a respiratory virus that’s most notorious for attacking babies but endangers their grandparents, too.
The move sets the stage for adults 60 and older to get vaccinated this fall — but first, the Centers for Disease Control and Prevention must decide if every senior really needs RSV protection or only those considered at high risk from the respiratory syncytial virus. CDC’s advisers will debate that question in June.
“This is a very exciting time with multiple potential RSV solutions coming out after years of really nothing,” said Dr. Phil Dormitzer, chief of vaccine research and development for GSK, formerly known as GlaxoSmithKline. Why has it taken so long to come up with a vaccine? The field suffered a major setback in the 1960s when an experimental shot worsened infections in children. Scientists finally figured out a better way to develop these vaccines — although modern candidates still were first tested with adults.
To see how long protection lasts, GSK is tracking study participants for three years, comparing some who get just one vaccination during that time and others given a yearly booster.There was a hint of a rare but serious risk — one case of Guillain-Barre syndrome, which can cause usually temporary paralysis, and two cases of a type of brain and spinal cord inflammation. The FDA said it was requiring the company to continue studying if there really is a link to the vaccine.
