Outline likely health benefits of universal PCV vaccination of children, other than reducing the incidence of ARI.

[2]

Markscheme
  1. less use of antibiotics;
  2. less antibiotic resistance (in pathogens) / antibiotics more successful at treating infectious/bacterial diseases;
  3. decrease in health care costs / less money spent on antibiotics;
  4. decreased mortality / protection of immune-deficient patients/non-vaccinated population/ achieve herd immunity;

Since the question already states “other than reducing the incidence of ARI”, this reason should not be accepted.
