Soon a vaccine on the market to fight against bronchiolitis? Pfizer is not that far off. The American laboratory shared, Tuesday, November 1, positive results for its respiratory syncytial virus (RSV) vaccine)responsible for the bronchiolitis.

An encouraging test
The vaccine showed itself 82% effective in preventing serious cases in a baby’s first three monthsand about 69% within six monthsaccording to the results of this phase 3 test, reports Le Figaro.
However, the laboratory did not conclude that vaccine reduced non-severe cases ‘statistically significantly’even if the tests show some clinical effectiveness, indicates The Parisian.
The results have not yet been reviewed by independent scientists. According 20 minutesthe American giant plans to request “authorization for the vaccine in pregnant women by the end of the year in the United States then in other countries“.
Waiting for the European Commission
