The World Health Organization says cases of the measles increased worldwide by 79% from 2022 to 2023. At least 45 cases of the vaccine-preventable disease have been reported in 17 states in the United States. Data reveals that 22 million infants missed at least one dose of the measles vaccine through routine immunization in 2022, partly due to the COVID-19 pandemic.
