VERGARA C, JORGE  y  QUEZADA L, ARNOLDO. Challenges of the Immunizations Extended Program (PAI): Chile 2006. Rev. chil. pediatr. [online]. 2007, vol.78, suppl.1, pp. 74-84. ISSN 0370-4106.  doi: 10.4067/S0370-41062007000600006.

The support given to infant immunization programs wishes to improve life quality and strengthen the public image of the government and its health ministry. At an international level, Chile has always been an example on public immunization, so it is necessary to examine our PAI, in terms of valency number administered in the public system versus private resources. In this document, a proposal by stages is made, according to costs, availability and most relevant epidemiologic data for new schemes. First Stage: Hepatitis B in newborns, Haemophilus influenzae b 4° doses and Hepatitis A in toddlers. Second Stage: combined vaccines with acellular Pertussis and injectable Polio vaccine. Third Stage: Chickenpox 1 dose and Rotavirus vaccines. Fourth Stage: conjugated anti pneumococcal vaccines and Human Papiloma Virus vaccine. In conclusion, the important progress on immunizations and the huge amount of resources invested worldwide show us the tendency that should be followed by our Health Ministry
