Posted on by

The Common Health Coalition has published its Spotlight Brief on the cost of Childhood Immunizations. Summary: This brief demonstrates how declines in childhood vaccination will carry substantial human and economic consequences, using measles as a case study. The modeling analysis, conducted by the Yale School of Public Health, finds that a sustained 1% annual decline in MMR vaccine coverage could lead to more than 17,000 measles cases, 4,000 hospitalizations, and 36 preventable deaths each year, while adding billions in avoidable costs across the US health system and economy by 2030.

Canada Loses Measles Elimination Status

Posted on by

Canada has formally lost its measles elimination status, the country’s public health agency announced Monday, meaning all of the Americas have lost that status as well. The decision, which was widely expected, comes after a meeting last week where an expert committee of the Pan American Health Organization determined that a large measles outbreak that began in Canada in October 2024 was still ongoing, more than 12 months after it started. It is reversible – if the country sees zero cases of measles in the next 12 months. However, Belize, Bolivia, Brazil, Mexico, Paraguay, and the US are currently battling ongoing measles Read More …

KFF: As Measles Exploded, Officials in Texas Looked to CDC Scientists.

Posted on by

Amy Maxmen, August 25, 2025. As measles surged in Texas early this year, the Trump administration’s actions sowed fear and confusion among CDC scientists that kept them from performing the agency’s most critical function — emergency response — when it mattered most, an investigation from KFF Health News shows. The report details multiple crises, both in Texas, where health facilities became overwhelmed and misinformation surged, all while federal health agencies faced communications crackdowns, stalled reports, and staff and budget cuts. Texas officials only heard from the CDC after a child died on February 26, meanwhile the outbreaks spread to five Read More …

Measles Cases Reach Highest Since Elimination

Posted on by

Over the weekend, the US reached 1,281 measles cases in 2025 – the highest number since the disease was declared eliminated in 2000, and the most we’ve seen since 1992 (2,126 cases). Thanks to high vaccination rates, we’ve managed to keep the disease at bay, but those rates are slipping. Since measles is the most contagious virus on Earth (that we know of), it’s often the first to resurge when vaccination coverage declines. A high case count doesn’t automatically mean the US loses its measles elimination status. That is defined by the WHO, and means that measles is not endemic Read More …
