Why Do We Need Yearly Flu Shots, but Not Measles Shots?

The video discusses the differences in immunity between measles and influenza viruses. Measles provides lifelong immunity with a stable vaccine, while influenza requires annual shots due to rapid mutations. The video explores the structure of these viruses, focusing on the HA and NA proteins in influenza, and the challenges in developing a universal flu vaccine. Research efforts include targeting the HA stem and using llama antibodies, with promising candidates like M-001 in trials.
