In 1991 the Universal Vaccination Program was created. This program is a sanitary policy which intends to provide specific protection against several infectious diseases throughout vaccination among the different age groups countrywide.

 

The execution of this Universal Vaccination Program is carried out basically by two strategies:

 

A Permanent Vaccination Actions Program.

 

An Intensive Vaccination Actions Program.

 

The Permanent Vaccination program will provide services to the population  that seek attention in health centers and hospitals along the country. Daily services during the weekdays are provided all year long. The purpose of this program is to ensure that children less than eight years old will initiate and complete their vaccination schedule.

 

On the other Hand, the Intensive Vaccination Program will be in charge of controlling epidemics caused by vaccine-preventable diseases in a short period of time. Initially, these actions took place during the National Immunization Days, which were later called the National Immunization Week, and currently know as the National Health Week.

 

In Mexico, 3 National Health Weeks will take place during the year.
