Health Indicator Report of Immunization - Childhood Coverage with 4:3:1:3:3:1:4, CASA Method

By two years of age, it is recommended that all children should have received 4 doses of diphtheria-tetanus-pertussis (DTaP), 3 doses of polio, 1 dose of measles-mumps-rubella (MMR), 3 doses of Hepatitis B, 3 doses of Haemophilis Influenza, type B (Hib), and 1 dose of Varicella vaccine. This series is referred to in shorthand as "4:3:1:3:3:1." This graph shows estimated levels of 4:3:1:3:3:1 coverage by New Mexico County, which helps target interventions where they are most needed.

Childhood Immunization Coverage With 4:3:1:3:3:1:4, Rates by County, New Mexico, 2014


Immunization coverage surveys were conducted at offices of selected Vaccines for Children (VFC) providers. VFC is a national program administered through CDC to ensure that all children 0-18 years of age are eligible to receive recommended vaccines regardless of their family's ability to pay for them.   **Reliable county data were not available for all New Mexico counties.

Data Interpretation Issues

2013 CASA Data by County: 217 New Mexico providers were assessed for immunization coverage of children during 2013. Children eligible for assessment were 2 years old in 2013 and had at least 3 lifetime visits to that practice, of which 2 were within the previous 12 months. Children were considered up-to-date if they had received 4 doses of DTaP, 3 doses of Polio, 1 dose of MMR, 3 doses of HIB, 3 doses of Hep B,1 dose of Varicella, and 4 doses of Pneumococcal vaccine by their second birthday. To estimate 'county' rates, each practice coverage rate was multiplied by a weighting factor representing the ratio of the number of eligible children in that practice to the total number of eligible children in all the county practices assessed. Adding these terms together gives a weighted estimate for the county. The smaller the number of practices surveyed, the less reliable the county estimate.


Children aged 24-35 months who have received the recommended vaccine series (4 DTaP, 3 Polio, 1 MMR, 3 HepB, 3 HIB,1 Varicella, and 4 Pneumococcal) by their second birthday.


Children aged 24-35 months old who meet visit criteria (those who have had at least two visits to the surveyed provider in the past year, and at least 3 lifetime visits to the provider) and have received the complete 4:3:1:3:3:1:4 series by their second birthday.


Children aged 24-35 months old who have had at least two visits to the surveyed provider in the past year, and at least 3 lifetime visits to the provider.

Other Objectives

Related to IID-17 Increase the percentage of providers who have had vaccination coverage levels among children in their practice population measured within the past year

Evidence-based Practices

The New Mexico Department of Health provides quality improvement visits to Vaccines for Children providers to promote best practices for immunizations. Measuring and tracking coverage rates helps providers diagnose missed opportunities for immunizations. NMSIIS, the state on-line immunization registry, tracks immunizations received so that children can be recalled to be brought up-to-date for any needed shots. The CDC Community Guide at provides evidence-based recommendations for universally-recommended immunizations.
