How does herd immunity work?
Oxford VaccineGroup・2 minutes read
Vaccines provide dual protection by shielding individuals from diseases and establishing herd immunity, crucial for vulnerable groups; however, reliance on herd immunity can lead to disease resurfacing, making vaccination the most effective defense for both individuals and society.
Insights
- Vaccines provide both individual protection against diseases like measles and contribute to herd immunity, safeguarding vulnerable populations like newborns, the elderly, and cancer patients.
- Relying solely on herd immunity without maintaining high vaccination rates can lead to the resurgence of diseases like measles, emphasizing the importance of vaccination as the most effective defense for both individuals and society.

How do vaccines protect individuals?
Vaccines shield individuals from infectious diseases like measles by providing over 99% protection with the MMR vaccine. They also establish herd immunity, preventing disease transmission and protecting vulnerable groups.
What is the importance of herd immunity?
Herd immunity is crucial as it shields vulnerable groups such as newborns, the elderly, cancer patients, organ transplant recipients, and non-responders to vaccines from potentially fatal illnesses like measles. It also prevents diseases from resurfacing in unvaccinated clusters.
What happens if vaccination rates drop?
If vaccination rates drop, diseases like measles can resurface, especially in unvaccinated clusters. This highlights the importance of maintaining high vaccination rates to prevent outbreaks and protect vulnerable members of society.
Who benefits from vaccination besides individuals?
Vaccination not only safeguards individuals from infectious diseases but also shields vulnerable members of society, such as newborns, the elderly, cancer patients, and organ transplant recipients, from severe illnesses like measles.
Why is vaccination considered the most effective defense?
Vaccination is considered the most effective defense as it provides over 99% protection from infectious diseases like measles and establishes herd immunity, preventing disease transmission and protecting vulnerable groups from potentially fatal illnesses. Maintaining high vaccination rates is crucial to safeguarding public health.

Vaccines: Shielding Individuals and Society from Diseases
- Vaccines offer dual protection: they shield individuals from infectious diseases like measles, with the MMR vaccine providing over 99% protection, and they prevent disease transmission, establishing herd immunity or herd protection. This safeguard is crucial for vulnerable groups such as newborns, the elderly, cancer patients, organ transplant recipients, and non-responders to vaccines, shielding them from potentially fatal illnesses like measles.
- While herd immunity is vital, it's not foolproof; if vaccination rates drop due to reliance on herd immunity, diseases like measles can resurface, especially in unvaccinated clusters. Vaccination remains the most effective defense, not only safeguarding individuals but also shielding vulnerable members of society from severe illnesses.
