Vaccine-Preventable Diseases are Rare So Vaccines Unnecessary

RecordOBS-0546
CategoryHealth/Vaccines
StatusDEBUNKED
SummaryThe claim that vaccines are no longer needed because diseases like polio and measles are rare in many countries. This ignores the fact that these diseases still circulate globally and can be imported, causing outbreaks among unvaccinated populations.
OriginThis argument has been used by anti-vaccine advocates since the mid-20th century, as vaccine success made these diseases less visible.
Claimed
  • Since vaccine-preventable diseases are rare, the risks of vaccination outweigh the benefits.
  • Herd immunity means I don't need to vaccinate my child.
  • Improved hygiene and nutrition have eliminated these diseases, not vaccines.
Evidence / consensusVaccine-preventable diseases have not been eradicated globally. They can be imported and cause outbreaks in unvaccinated communities. The decline in these diseases is directly attributable to vaccination. Herd immunity requires high vaccination rates to protect vulnerable individuals.
> OBSERVER NOTE:
The success of vaccines has become their own worst enemy-complacency. The diseases are rare precisely because we vaccinate. Stop vaccinating, and they will return.
