What does the "expanded program on immunization" focus on?

The focus of the "expanded program on immunization" is on ensuring that mothers and infants have access to routine vaccinations. This program aims to increase immunization coverage, providing essential vaccines that protect against various diseases, thus promoting public health. By prioritizing vaccination for mothers and infants, it helps to prevent illness and reduce mortality rates associated with vaccine-preventable diseases.

The other options do not align with the primary goals of immunization programs. For instance, promoting the sale of infant formulas or advertising breastmilk substitutes does not contribute to vaccination efforts and instead focuses on feeding practices. Political policies on breastfeeding, while pertinent to maternal and child health, are separate from the objectives of vaccination programs, which are dedicated to preventing disease through immunization rather than discussing breastfeeding approaches.
