Vaccines are widely considered among the greatest public health achievements of the last century. Diseases that previously killed thousands of children in the United States per year are now unheard of to most families. Over time, New York State has seen important increases in childhood vaccination rates. Yet, New York has also seen outbreaks of vaccine-preventable diseases in recent years. In addition, children of color have historically faced barriers to vaccine access, creating disparities in vaccination coverage. It is critical to further increase vaccination rates to prevent the return of diseases we had relegated to the past. An early childhood series of vaccines, as recommend by the Advisory Committee on Immunization Practices (ACIP), protects against 11 illnesses, including measles, mumps, and chickenpox. This report examines early childhood vaccination coverage in New York State from 2018 to 2020. Vaccination coverage refers to the percentage of children who completed the entire early childhood vaccine series by the age of 24 months. Data on childhood vaccination were made available through the New York State Immunization Information System (see more details on the data in the Methods section). The report also presents disparities in vaccination coverage by race, ethnicity, and geography to identify communities of undervaccinated children in need of targeted outreach. Finally, the report discusses factors that may have increased vaccination coverage over time and suggests additional steps to protect all children from vaccine-preventable diseases.
