[Respiratory syncytial virus vaccines].

RESPIRATORY SYNCYTIAL VIRUS VACCINES. Respiratory syncytial virus (RSV) is responsible for lower respiratory infections, particularly in children under five years of age (acute infant bronchiolitis) and the elderly over 60. Monoclonal antibodies (palivizumab and nirsevimab) are used to prevent bronchiolitis. Four types of vaccine are currently under development: subunit vaccines composed of recombinant proteins or viral pseudoparticles, messenger RNA vaccines, recombinant vector vaccines and live attenuated vaccines. They are indicated for pregnant women to protect infants against bronchiolitis in the first months of life, and for people over 60 or with comorbidities.
