What happened
Ars Technica's headline reports that Moderna and Merck say their personalized mRNA cancer vaccine cut death and recurrence by 42% in melanoma. The retrieved page body contains only the site's cookie-consent and privacy boilerplate — no trial size, endpoint definitions, follow-up duration, comparator details, or peer-review status — so the 42% figure cannot be checked from this text.
Why it matters
Nothing actionable here for builders: the only concrete number (42%) comes from a company claim in a headline, with no data in the retrieved text to confirm whether it is a hazard ratio, a relative risk reduction, or over what period. If you want to discuss it, wait for the trial data or reporting that states the endpoint and sample size rather than repeating the 42% as established.
Discussion angle
Use it as a two-minute example of headline-vs-source discipline: the page we fetched had zero trial content, so what would you need to see (n, endpoint, follow-up, peer review) before repeating a 42% claim?
