What is the relationship between reducing infant mortality and universal immunisation?

Correct answer: Immunisation helps reduce infant deaths by preventing preventable diseases

Direct answer: A is correct. Immunisation prepares the body to resist particular infectious diseases and is an important part of child-survival efforts. When infants and children receive recommended vaccines through health services, their risk from several preventable diseases can be reduced. Lower illness and complications can contribute to lower infant and child mortality, although survival also depends on nutrition, sanitation, timely treatment and other care. B is wrong because the purpose of immunisation is disease prevention, not increasing deaths. C is wrong because prevention of serious childhood infections is connected to survival. D is wrong because immunisation programmes include children and are not restricted to adults. Memory cue: vaccination prevents disease; prevention supports survival.
