what is the rsv vaccine for

The RSV (respiratory syncytial virus) vaccine is designed to prevent lower respiratory tract disease caused by RSV. RSV is a common respiratory virus that can cause mild, cold-like symptoms in most people, but it can lead to serious complications, especially in infants and older adults. The vaccine is particularly recommended for adults aged 60 and older, especially those with weakened immune systems, chronic medical conditions such as heart or lung disease, or those living in nursing homes. The vaccine works by causing an immune response that can protect individuals from respiratory disease if they are infected with RSV in the future. The FDA has approved two RSV vaccines for adults 60 and older, and the CDC recommends that adults age 65 and older get an RSV vaccine. The vaccine is a single shot that provides protection against RSV disease for at least two winter seasons, with one dose being 83% effective in preventing lung infections during the first RSV season after vaccination.
