A new study in Science Advances looked at RSV spread and vaccination plans. The researchers used hospital records and patterns from places with different population density to test strategies.
The study says RSV causes many infant lung infections and about 80,000 hospitalizations in the US each year for children under five. A vaccine for pregnant women and an antibody for infants are now given by season.
The models showed city areas have year-round virus presence, while rural areas have short, sharp outbreaks. Seasonal vaccination lowers hospitalizations but may raise the chance of a summertime outbreak. The authors recommend offering RSV immunizations year-round for pregnant women in the recommended window and for young children. Funding came from US research institutes.
