How this receipt has changed
Staying up to date with COVID-19 vaccines and boosters can help prevent COVID-19 infection and protect against severe illness.
This receipt has not been rewritten since it was published on 03 Oct 2026. Its current version is 1.
Weight is the one the receipt's balance bar uses: every source counts 1, plus a bounded bonus for how often it has been cited, so one famous paper cannot outweigh three dissenting ones (at most 3x a bare source). It is a reading aid built from facts the receipt already stores, not the engine's confidence.
