Herd immunity primarily protects which group?

Herd immunity primarily protects which group?

• A. Individuals who cannot be vaccinated due to medical reasons
• B. Only children who receive vaccines
• C. Only healthcare workers
• D. People who refuse vaccines

Answer: (A)

Herd immunity works to stop the spread of disease so that those who cannot be vaccinated are protected. The group most helped are individuals who cannot receive vaccines for medical reasons—such as people with immune suppression, very young infants, or others with contraindications. When a large portion of the population is immune, the chance that the virus or bacteria spreads is greatly reduced, shielding these vulnerable individuals even though they themselves aren’t vaccinated. Other groups, like those who are vaccinated, gain personal protection, but they’re not the primary beneficiaries of herd immunity. People who refuse vaccines don’t receive this indirect protection, especially if vaccination coverage is not high enough to interrupt transmission.
