Jarvis: A cancer vaccine is closer than ever (opens the original)
Read excerpt
Scientists are on the cusp of fulfilling a decades-long quest: to use vaccines to teach the immune system to spot and destroy cancer cells. News that an mRNA cancer vaccine developed by Merck & Co. and Moderna Inc. kept melanoma from returning in a large, late-stage trial marks a critical next chapter for a technology beleaguered by post-pandemic political backlash and years of false starts before then. The concept of cancer vaccines has been kicked around for over a century, and in the past 20
Jarvis: Is lettuce safe? Probably. Will cyclospora spur change? Hopefully. (opens the original)
Read excerpt
For the last month, Americans have viewed their lunchtime salads or even a single, crisp leaf of iceberg on their burger as a possible threat. Could it harbor cyclospora, the explosive-diarrhea-causing parasite that by early August had sickened thousands, hospitalized hundreds, and led to two deaths?

Jarvis: No Surprises Act could shock healthcare system (opens the original)
Read excerpt
When the No Surprises Act took effect in 2022, it was a rare feat of bipartisan problem-solving. The law was meant to prevent a once all-too-common scenario: An insured patient would seek emergency care, only to face financial disaster because one of the providers involved was outside the patient’s insurance network. The law took that problem out of patients’ hands, requiring insurers and out-of-network doctors to settle on a fair payment. That protection has spared millions of Americans from un
