The Resurgence of Measles and Vaccine Hesitancy

Measles is experiencing a resurgence due to decreased vaccination rates and the anti-vaccine movement, which directly impacts public health. Historical context is provided through the 2018-2019 outbreak in New York City, which highlighted vulnerabilities in specific communities, especially those with higher exemptions from vaccinations. The discussion indicates how interruptions in immunization programs, exacerbated by the COVID-19 pandemic, have contributed to diminished coverage and increased hesitancy in vaccine uptake. This situation necessitates urgent attention to ensure that vaccination programs are reinstated and strengthened to avoid further outbreaks.
