To gain access to our Healthcare Customers clinical settings, field sales, field service, and other customer facing professionals are required to register with the vendor credentialing organization associated with the Healthcare Customers, complete the Healthcare Customers' required process, and undergo a series of clearances. Many of our Healthcare Customers require outside vendors like us to present proof that they have certain requisite vaccinations and immunizations, including, but not limited to, vaccinations against COVID-19 and seasonal influenza, before being granted entry into the Healthcare Customers' clinical settings.
