​​​​​​​Vaccine Preve​​ntable Diseases

APHL promotes the role ​of state and local public health laboratories in the detection and surveillance of vaccine preventable diseases (VPDs) by improving knowledge, providing trainings and ensuring quality information exchange.

Before the development of vaccines for measles, mumps and rubella (MMR) and diphtheria, tetanus and pertussis (DTP), morbidity and mortality from these diseases were significant in the US. The widespread use of the MMR and DTP vaccines has reduced cases, making these diseases rare.

However, recent measles outbreaks and the resurgence of mumps and pertussis across the US have demonstrated that public health laboratories must maintain the capability and capacity to respond effectively to re-emerging VPDs through routine surveillance, and diagnostic and confirmatory testing. They use a combination of diagnostic techniques, including culture, serology, antigen detection and PCR, to detect and characterize VPDs.​

Vaccine Preventable Diseases Reference Centers 

Enrolled PHL VPD Reference Center Assignments - Viral and Bacterial

APHL and CDC established four Vaccine Preventable Diseases Reference Centers to support testing for all public health laboratories. The California Department of Health-Viral and Rickettsial Disease Laboratory, Wadsworth Center-NYSDOH, Minnesota Department of Health and Wisconsin State Laboratory of Hygiene serve as the VPD Reference Centers.

The VPD Reference Centers perform molecular testing for seven VPDs (measles, mumps, rubella, varicella zoster virus, Bordetella pertussisHaemophilus influenzae and Neisseria meningitides) on behalf of other public health laboratories that have enrolled as submitting sites. The Reference Centers also offer proficiency testing for molecular testing for VPDs to other public health laboratories.​​​
