Mechanism of action

These vaccines contain a stabilized prefusion form of the RSV fusion (F) glycoprotein, which is a key target for neutralizing antibodies. By presenting this antigen, the vaccines stimulate both humoral and cellular immune responses that protect against RSV infection and disease severity. They are indicated for prevention of RSV-caused lower respiratory tract disease in older adults and infants.
