Vaccines: defense against infectious diseases1

One of public health’s greatest accomplishments is the development of vaccines. These immunizations help keep children from getting certain dangerous vaccine-preventable diseases. California continues to work to improve the number of children vaccinated with up-to-date coverage for the ages of 19-35 months.

One of the State’s biggest barriers to reaching the Let’s Get Healthy California 80% target by 2022 is false information and fears surrounding the long term effect and dangers of vaccinations. Despite recent challenges including public protests, progress continues to be made through collaboration between parents, childcare providers, medical providers, and other key stakeholders.

Indicator Progress

In 2010 (baseline year), 54.1% of children ages 19-35 months were up-to-date on vaccinations. The most recent data available show 68.6% (2017). We hope to reach a target of 80.0% or higher by 2022.
