Vaccination provides long-lasting 97% protection against measles infection. Most people who have been vaccinated do not need to be vaccinated again.

The COVID-19 vaccine has prompted more than 10 times as many reports of adverse symptoms than the measles vaccine.

A hospital in Texas on Wednesday confirmed the death of an unvaccinated child who was infected with measles—the first fatality in a two-state measles outbreak that began in January, according to the Associated Press.
