RSV vaccine development

RSV (Respiratory Syncytial Virus) vaccine development involves creating a shot that safely instructs the immune system to recognize and fight the virus, preventing severe respiratory illnesses in infants, older adults, and vulnerable populations. Researchers study the virus's structure to identify key targets for immunity, design vaccine candidates using various technologies like protein subunits or mRNA, and conduct clinical trials to ensure safety and effectiveness. Challenges include ensuring the vaccine works across different age groups and virus strains. Progress has led to promising candidates, with some nearing approval, aiming to reduce the significant health burden caused by RSV infections.
