COVID-19 Vaccine Mandate Fundamentals for Healthcare Employers


Now that OSHA has issued its emergency temporary standard and CMS has issued its own emergency rule, the landscape has changed once again for healthcare employers in terms of addressing employees’ vaccination status.  Fortunately, they now have much more certainty, which allows for more specific and detailed planning to address the myriad vaccination-related requirements that apply for healthcare entities.  The following sets forth key details that healthcare employers should understand as they are establishing their compliance strategies for these obligations.

What different vaccine-related requirements may apply?

For healthcare employers, there may be at least four different vaccine-related legal obligations that apply:

  1. The generally applicable OSHA emergency temporary standard broadly requires employers with 100 or more employees, company-wide, to either (a) ensure that the employees are vaccinated against COVID-19 or (b) have those employees provide verified negative tests on a weekly basis.

  2. The CMS emergency rule requiring that staff at healthcare facilities participating in Medicare and Medicaid be fully vaccinated.

  3. President Biden’s Executive Order requiring that federal contractors and subcontractors ensure employees are fully vaccinated against COVID-19.

  4. State-specific requirements in at least 21 states which have issued their own rules requiring healthcare employers to ensure that employees are fully vaccinated (although some allow for negative tests instead, similar to the general OSHA ETS).

When must an employer satisfy these obligations?

Healthcare employers should begin taking steps immediately to address these obligations, if they have not done so already.  Although the White House deferred the testing deadlines under the general OSHA ETS to January 4, the CMS rule requires staff at all covered health care facilities to have received their first dose of a two-shot vaccine or a single dose of a single-shot vaccine to have received those doses by December 5.  Covered healthcare employees who have failed to do so by December 5 may not treat patients.  Even for employers covered only by the general OSHA ETS, that rule requires employees to be “fully vaccinated” by January 4, which can require 6-8 weeks for employees who receive two-dose vaccines, so it is important to begin acting as soon as possible.

How do these various requirements interact with each other?

Employers should prepare to satisfy the most stringent requirements that apply of these various rules.  The OSHA ETS is less stringent than the CMS rule, federal contractor requirements, and some state requirements, but the OSHA ETS expressly provides that it does not supersede or negate those requirements.  For example, although the OSHA ETS requires either vaccination or weekly negative tests, the Executive Order for federal contractors does not.  So, a federal contractor or subcontractor should ensure that covered employees are fully vaccinated by January 4, rather than preparing to rely on negative tests.  Likewise, an employer in a state that requires full vaccination for healthcare employees may not generally rely on weekly negative tests.

How can employers practicably manage these obligations?

Although these rules impose significant requirements on covered employers, they do leave some room for steps that can mitigate the costs and burdens that they create.  An employer’s options will depend on its specific situation, including the states where it employs people, whether it serves as a federal contractor or subcontractor, and the portion of its workforce that has opposed vaccination thus far.  Nevertheless, as an employer is considering how to manage its obligations, it should consider the following factors that may provide at least some relief:

As employers continue working to address these numerous and developing obligations, they should continue to watch for further guidance, and consider involving professionals who are knowledgeable about the landscape.  While the compliance obligations are expanding, employers and their advisors also have expanded their ‘playbooks’ of practical steps that can help reduce the issues that these requirements create.
