Why does measles vaccine last for life?
Measles is an example of a stable virus that is unlikely to replicate, so scientists could predict that immunity would last a long time, which it does.” Smallpox and polio, highly contagious viruses that were almost eradicated through vaccination, are also stable with low mutation rates.
