Infections and vaccines

Evidence checks about infection headlines, vaccines, COVID, flu, immunity, antivirals, sepsis and public-health claims.

What to watch for

Common ways headlines can go too far

  • Lab findings framed as clinical protection
  • Population surveillance used without enough confounding context
  • Safety signals presented without denominator or risk comparison

Infection and vaccine headlines need careful separation of lab evidence, surveillance data, clinical outcomes, safety signals and public-health interpretation.

Common hype patterns

  • Lab or immune-marker findings framed as clinical protection.
  • Population surveillance reported without enough confounding context.
  • Safety signals presented without denominator, comparator or severity context.
  • Early antiviral or vaccine findings generalised beyond the studied setting.

Questions to ask before trusting the headline

  • Was the claim tested in people, or only in cells, animals or models?
  • Is the outcome something patients notice, or only a surrogate marker?
  • Does the headline distinguish association from causation?
  • Are absolute risks, comparators and uncertainty shown clearly?
  • Would the finding change real-world behaviour, or is it mainly hypothesis-generating?

How deHype.io reads this topic

deHype.io separates the public claim from the underlying evidence. The aim is not to dismiss early science, but to show whether the headline has kept the finding in proportion.
