## Key points

- An unvaccinated child’s measles death is New York’s first in over 30 years.
- Two MMR doses usually give long-lasting protection.
- Flu vaccines are updated annually as the virus changes and immunity wanes.

## Summary

An unvaccinated child in Lewis County, upstate New York, has died after contracting measles, the state’s first known measles-associated death in more than 30 years. The case comes during a historic outbreak and highlights the role of vaccination: measles can be especially dangerous for young children, while the two-dose MMR series gives most people long-lasting protection.

Whether a vaccine needs boosters depends mainly on how much the infection changes and how long immunity lasts. Flu viruses evolve frequently, so vaccines are updated each year to target strains expected to circulate; protection also wanes over time. Measles changes less in the parts recognised by the immune system, so protection after two doses often lasts for decades or life, while tetanus and diphtheria boosters are generally recommended every 10 years.
