Answer 1

Meena cannot be vaccinated because of her allergies, but she is protected to some degree from catching childhood diseases because of herd immunity.

• But if one stays away from infected persons of the from the agents causing the disease, his chances of contracting the disease reduce substantially.
• In Meena's case, 90% population in her community is free of the disease. Hence, the possibility of Meena contracting the disease is very less.
