Vaccine Questions
Looking for a specific answer?
Start with existing explainers on autism, HPV, side effects, Yellow Card reports, safety signals and how vaccine safety is monitored.
Browse Vaccine Questions →Neutral evidence literacy
Examine the evidence.
Not the label.
Clear explanations of vaccine claims, controversies, safety information and changing evidence—without political or ideological framing.
What inclusion means: a claim, report or controversy appears here because it merits explanation or context. Inclusion does not mean endorsement, confirmation or cause for alarm.
What this project is
ANTIVAX.co.uk is not anti-vaccine.
It is a neutral evidence-literacy project examining vaccine claims, controversies and safety data without slogans or tribal framing. It helps readers understand what evidence can—and cannot—show and links to identifiable and primary sources wherever practical.

Explore visually: three pathways into the evidence
Each visual pathway starts from a different reader need: checking a claim, understanding risk, or following how a controversy developed. Together they help readers move from a headline or concern to evidence, context and a fuller source trail.
Guide
How to interpret evidence
Check the question, source, design, population, result, uncertainty and wider evidence before accepting a conclusion.

HPV vaccine: what does the evidence show?
A structured look at effectiveness, common side effects, continuing safety surveillance and the evidence around infertility claims.
Read evidence review →How vaccine safety monitoring works
How clinical trials, post-authorisation surveillance, safety signals and regulatory investigation fit together.
Read explainer →How to read Yellow Card reports
Why a suspected-reaction report is useful for detecting a possible signal, but does not by itself establish causation.
Read guide →How evidence is selected
Higher-quality evidence carries more weight.
For significant medical claims, the site prioritises systematic reviews and well-conducted meta-analyses, large well-designed studies, regulatory assessments and clinical or public-health guidance. Individual studies, spontaneous reports, case reports and anecdotes are considered in context rather than treated as equivalent forms of proof.
Where sources disagree, the aim is to describe the disagreement, study quality, limitations and uncertainty rather than select only the most striking conclusion.

Claims checked. Context added.
Search 20 claims about autism, MMR, aluminium, thiomersal, HPV, Yellow Card reports, vaccine safety and evidence interpretation. Each entry gives a concise evidence status and routes you to the deeper explanation.
Evidence Updates
What an update means
Evidence Updates are dated summaries of newly published or newly reviewed source material already covered by the site. They record what the source says; publication here does not mean endorsement or that a final conclusion has been reached.
