We Monitor Philadelphia’s Immunization Rates

High immunization rates protect us all from diseases. The Philadelphia Department of Public Health works hard to increase and maintain vaccination rates across the city. As a result of this work, Philadelphia has very low numbers of vaccine preventable diseases.

The Immunization Program keeps Philadelphia’s vaccination rates high by:

  • Educating providers about vaccine recommendations
  • Supporting providers with tools that help them identify, vaccinate, and follow up with their patients
  • Encouraging people to get their shots and to vaccinate their children according to recommended schedules
  • Distributing vaccines at no cost to providers enrolled in our VFC and VFAAR programs

1. Vaccine Coverage Rates

The charts below compare vaccine coverage rates of individuals 24 to 35 months of age who completed their vaccine series by 24 months of age, in 2020 and 2021.

The charts below compare vaccine coverage rates of individuals who completed their vaccine series by 13 months of age, in 2020 and 2021.

2. COVID-19’s Effect on Vaccination Rates in Philadelphia

COVID-19 has impacted all of society and routine vaccines are no different. Since March 2020, we have seen a significant drop in pediatric and adult vaccinations across Philadelphia. Conversations with providers and clinicians reveal a range of patient concerns from fear of exposure to COVID-19 in a medical setting to misconceptions of vaccine safety. Regardless of the reason, the more Philadelphians miss their routine vaccines the less protected our city becomes to another outbreak.

The Philadelphia Immunization Program is doing everything in our power to return immunization rates to pre-COVID-19 levels. In the interest of making our efforts more transparent, we are publishing data from our Immunization Information System (IIS). See below for the most recent immunization charts for both pediatric and adult immunizations.

The two graphs below present data with COVID-19 Vaccine data included.

3. How Providers Can Help

When we keep immunization rates high, we protect ourselves and each other from dangerous diseases. When our city has high immunization rates, it means that:

  • People who are immunized don’t get sick
  • We help protect those who can’t be immunized due to certain medical conditions
  • We stop diseases before they start
  • Students stay in school, adults can keep working, our society is healthier, and our economy saves money
