Study: Vaccine Rollouts Cut Deaths and Infections by 60%

A recent study analyzed emergency vaccination programs implemented for five major infectious diseases, revealing a significant impact on mortality rates. The research, spanning 23 years and encompassing 210 incidents across 49 countries, found that vaccine rollouts reduced deaths by approximately 60% and prevented a similar number of infections. Moreover, the study highlighted substantial economic benefits, estimating savings of around $32 billion, primarily through averted deaths and disabilities. These findings underscore the crucial role of vaccination in controlling outbreaks and mitigating their devastating consequences.

Measles Surges in US as Vaccine Hesitancy Fuels Record Highs

The United States is experiencing its worst measles outbreak in a quarter-century, surpassing the 2019 record with at least 1,277 confirmed cases in 2025. A major outbreak in West Texas, linked to low vaccination rates, has been a primary driver, with additional cases connected to the outbreak appearing across the country. The highly contagious nature of measles, coupled with declining vaccination coverage and vaccine hesitancy, has resulted in multiple deaths and outbreaks in various states, threatening the nation’s measles elimination status. Experts suggest the actual number of cases is likely significantly underreported, further escalating the public health concern.

Measles Cases Hit Record High Amidst Vaccine Hesitancy Crisis

Measles cases in the U.S. have reached a record high, exceeding the 2019 peak and marking the worst outbreak since the 1990s.
