In healthcare, human factors are an essential component of mitigating risk for both patients and the workforce. This reality is becoming increasingly evident as the U.S. faces measles outbreaks across communities in 48 states, driven by the loss of herd immunity. Herd immunity refers to the protection that builds within a community when more than 95% of that group is vaccinated against a disease like measles. According to a recent CDC report (July 30, 2026), with vaccination rates falling below that threshold, many communities have lost this protection and outbreaks have returned, bringing challenges that many healthcare professionals haven't seen in decades.
Due to the highly contagious nature of measles and its spread through direct contact and airborne droplets, exposure can occur quickly and easily.
As of August 2026, Pennsylvania cases have risen to nearly 500, including the state's first measles death in 35 years. This outbreak also prompted two major facilities, Geisinger Health and Milton S. Hershey Medical Center, to issue public warnings through local media about possible patient exposures.
While this places significant demands on healthcare workers caring for patients, it also raises a separate and urgent concern for the workforce itself.
Historically, healthcare facilities enforced mandatory vaccination policies for diseases such as MMR, varicella, influenza, hepatitis B and COVID-19 to protect vulnerable patients. However, federal laws enforced by the U.S. Equal Employment Opportunity Commission (EEOC) now require employers to consider reasonable accommodations for unvaccinated workers. In practice, this frequently means requiring unvaccinated healthcare workers to mask as a precaution against transmission.
With growing numbers of individuals declining vaccination, the likelihood of someone entering a healthcare setting while unknowingly infected is also rising. This applies not only to patients and visitors but to contractors and medical vendors who may be involved in direct patient care. This reality signals a clear need for healthcare facilities to have real-time visibility into the vaccination status of medical representatives, so they can deploy appropriate precautions quickly during an outbreak.
As part of our vendor credentialing platform, OR Trax ensures proper documentation of immunizations including MMR, influenza, varicella, hepatitis and COVID-19. Declination forms and proof of immunity are also accepted. In the event of an outbreak or elevated-risk scenario, these credentials can be acted on immediately by toggling a setting that requires a vendor to use protective gear. Activation happens in real time and is reflected directly on the OR Trax digital badge.
Despite strong scientific evidence supporting the MMR vaccine as safe and effective against measles, not everyone will choose to be vaccinated. That is their right under federal law and must be accommodated. But knowledge is power, and the consistent use of PPE can meaningfully reduce the risk of transmission.
This is not about changing personal decisions. It is about shifting behaviors to prioritize infection prevention. Keep it unbiased, keep it grounded in credentials, and don't make it personal.
