Vaccination Rates At Colonial Schools: See Newly Revealed Data

PLYMOUTH MEETING, PA — Vaccination rates are now publicly available at public schools across Pennsylvania, including in Plymouth and Whitemarsh.

The Pennsylvania Health Department's new interactive table shows what percentage of students at different schools have been vaccinated against measles, polio and other diseases during the 2025-26 school year.

Vaccination rates for Colonial School District are listed below:

Plymouth Elementary School

• Students: 159
• DTaP vaccine: 92.5%
• Polio: 92.5%
• MMR (measles, mumps, rubella): 93.7%
• Hepatitis B: 97.5%
• Varicella (chickenpox): 93.7%
• Tdap: not reported (blank in state data — this vaccine isn't tracked at kindergarten level)
• Noncompliant with vaccinations and attending school: 0.0%

Plymouth-Whitemarsh High School

• Students: 408
• DTaP vaccine: 98.0%

Previously, school vaccination rates were only publicly accessible at the state and county levels. Health officials say the public deserves as much accurate information as possible in the face of misinformation and conspiracy theories that have created mistrust in longstanding medical guidance, sparking a resurgence of diseases once considered eliminated.

When 95 percent of people in a community have received the measles, mumps, and rubella (MMR) vaccine, most people are protected through herd immunity, according to the CDC.

State health officials shared vaccination data for kindergarteners, seventh-graders and high school seniors from last school year. Enrollment figures also include home-schooled students who would otherwise attend that public school.

Here's what each listed vaccine means:

• DTaP: Diphtheria, Tetanus, acellular Pertussis (whooping cough) — given to babies and young children
• MMR: Measles, Mumps, Rubella
• Hep B: Hepatitis B
• Varicella: Chickenpox
• Tdap: Tetanus, Diphtheria, acellular Pertussis (whooping cough) — given to older children and adults
