To get a medical exemption for the COVID vaccine, you need a licensed healthcare provider to document that you have a CDC-recognized reason to avoid the shot, submit that documentation to whoever is imposing the requirement, and respond to any follow-up questions during their review. If your employer is the one mandating the vaccine, the Americans with Disabilities Act also gives you the right to a reasonable accommodation once the exemption is approved.
Before you start, make sure a mandate actually applies to you. OSHA withdrew its large-employer vaccination-or-testing rule in January 2022.1Occupational Safety and Health Administration. COVID-19 Vaccination and Testing ETS The CMS mandate for staff at Medicare- and Medicaid-certified healthcare facilities expired in April 2025.2Centers for Medicare and Medicaid Services. Interim Final Rule – COVID-19 Vaccine Immunization Requirements for Residents and Staff Private employers can still set their own policies, and some hospitals, clinics, long-term care facilities, and colleges continue to require vaccination. The process below is for those situations.
Medical Conditions That Qualify
The CDC recognizes a narrow set of medical reasons to avoid a COVID-19 vaccine, and it splits them into two categories: contraindications and precautions. Which category your condition falls into shapes both how strong your case is and whether the exemption is permanent or temporary.
Contraindications
The only true contraindication the CDC recognizes is a documented severe allergic reaction, such as anaphylaxis, after a previous dose or to a known vaccine ingredient.3Centers for Disease Control and Prevention. Contraindications and Precautions – Covid Even in this case, you may still be eligible for a different vaccine type than the one that caused the reaction. This is the strongest basis for a medical exemption.
Precautions
Precautions are conditions where vaccination might carry elevated risk but the benefit could still outweigh that risk. The CDC lists:
- A non-severe allergy to a vaccine component, where an alternative vaccine type may be given instead.
- A non-severe immediate allergic reaction (within four hours) after a previous dose, again allowing an alternative vaccine type.
- Myocarditis or pericarditis within three weeks of a previous dose, where subsequent doses should generally be avoided.
- A history of MIS-C or MIS-A, where the decision should be made with a specialist.
- Moderate or severe acute illness, where vaccination should be deferred until the illness improves.
All of these come from the CDC’s clinical guidance table.3Centers for Disease Control and Prevention. Contraindications and Precautions – Covid Conditions in the precaution category often lead to temporary deferrals rather than permanent exemptions. Acute illness clears. Myocarditis or pericarditis after a prior dose sits closer to a permanent exemption because the CDC says further doses “should generally be avoided,” though a reviewer may still set a date to reassess. Ask your provider to state clearly whether your exemption should be time-limited or ongoing.
What Does Not Qualify
General allergies to foods, pets, or environmental triggers do not support a medical exemption unless the specific allergen is also a vaccine ingredient. Pregnancy is not a qualifying condition; the CDC recommends vaccination during pregnancy because COVID-19 raises the risk of severe illness, hospitalization, and complications like preterm birth. Fertility concerns are also not supported, as COVID-19 vaccines have not been linked to fertility problems in women or men.4Centers for Disease Control and Prevention. COVID-19 Vaccination for Women Who Are Pregnant or Breastfeeding A provider may identify other clinical reasons in an individual case, but those are uncommon and face heavier scrutiny.
What Your Doctor’s Documentation Needs to Say
Your exemption stands or falls on the certification from a licensed healthcare provider. That can be a physician, physician assistant, or nurse practitioner, as long as they’re licensed and practicing within scope in your state. Some reviewers prefer a relevant specialist, such as an allergist for anaphylaxis history or a cardiologist for myocarditis, so check the specific requirements where you’re applying.
The letter or form needs to do three things: identify your specific medical condition, explain why vaccination is medically inadvisable for you, and state whether the exemption should be temporary or permanent. Vague language like “patient has health concerns” will almost certainly be rejected. The documentation should reference your medical history and any relevant test results, and it should tie the condition directly to a recognized contraindication or precaution.3Centers for Disease Control and Prevention. Contraindications and Precautions – Covid
Many employers and schools have their own exemption form with fields for patient information, the medical reason, and the provider’s signature and credentials.5Memorial Sloan Kettering Cancer Center. COVID-19 Vaccination Medical Exemption Process If one exists, use it. Submitting a free-form letter in place of the required form is a common reason requests get bounced back.
Submitting the Request
Where the request goes depends on who’s imposing the mandate. Employers typically route these through Human Resources or an Employee Health department. Schools use a student health portal or the registrar. Follow the organization’s format instructions exactly, whether that’s online upload, email, or physical mail. Online portals have the advantage of generating an automatic paper trail.
Confirm receipt after you submit. Portals usually send an automatic confirmation or reference number. If you sent your materials by mail or in person, follow up with a short email asking the reviewing office to confirm they have them. If your request gets lost, you don’t want to find out weeks later when you’re flagged as non-compliant.
The Review Process
A designated committee or department, not your direct supervisor, reviews the request. Review typically takes around two weeks, though timelines vary. During that period the reviewing body may contact you or your provider with follow-up questions, ask for additional records, or request clarification. This back-and-forth is called an interactive process.5Memorial Sloan Kettering Cancer Center. COVID-19 Vaccination Medical Exemption Process Respond quickly. Delays on your end can stall or sink the request.
You’ll get one of three outcomes: approval, denial, or a request for more information. Approvals often come with conditions such as periodic testing, mask-wearing, or other safety measures. Denials should include a written explanation.5Memorial Sloan Kettering Cancer Center. COVID-19 Vaccination Medical Exemption Process If your approval carries an expiration date, mark it and start renewal paperwork early.
Your ADA Rights If Your Employer Requires the Vaccine
Under the Americans with Disabilities Act, an employer must provide a reasonable accommodation to an employee whose disability prevents vaccination, unless doing so would cause the employer “undue hardship.”6U.S. Equal Employment Opportunity Commission. What You Should Know About COVID-19 and the ADA, the Rehabilitation Act, and Other EEO Laws The statute frames this as a prohibition on failing to make reasonable accommodations for known limitations of a qualified individual with a disability.7Office of the Law Revision Counsel. 42 USC 12112 – Discrimination
What Accommodations Look Like
The EEOC has identified several accommodations employers can offer to an unvaccinated employee with an approved exemption:
- Wearing a face mask in the workplace.
- Working at a physical distance from coworkers and visitors.
- A modified shift to reduce contact with others.
- Periodic COVID testing as a condition of entering the workplace.
- Telework when the job allows it.
- Reassignment to a role that doesn’t require vaccination.
These come directly from EEOC guidance.6U.S. Equal Employment Opportunity Commission. What You Should Know About COVID-19 and the ADA, the Rehabilitation Act, and Other EEO Laws Your employer doesn’t get to pick the most burdensome option; the process is meant to be a cooperative discussion about what works for both sides.
When an Employer Can Say No
“Undue hardship” means significant difficulty or expense in light of the employer’s size, resources, and operations. A small medical practice where every employee has direct patient contact may have a stronger case than a large corporation with many desk-based roles. The determination must be individualized. An employer cannot rely on blanket policies or coworkers’ discomfort with your unvaccinated status to deny your request.8U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Reasonable Accommodation and Undue Hardship under the ADA
Confidentiality
Your employer must store vaccination status, exemption documentation, and related medical information separately from your regular personnel file. Access is limited to people who need the information to do their jobs, and those people are bound to keep it confidential.6U.S. Equal Employment Opportunity Commission. What You Should Know About COVID-19 and the ADA, the Rehabilitation Act, and Other EEO Laws If a manager casually mentions your exemption to the team, that’s a problem HR needs to address.
If Your Exemption Is Denied
A denial isn’t always the end. Read the written explanation carefully. Often the issue is incomplete documentation rather than a substantive disagreement about your condition, and your provider can supply the missing pieces so you can ask for reconsideration.
If you believe your employer denied a legitimate medical exemption or refused to engage in the interactive process, you can file a charge of discrimination with the Equal Employment Opportunity Commission. You have 180 calendar days from the date of the discriminatory action to file, or 300 days if your state has its own anti-discrimination agency with a worksharing arrangement.9U.S. Equal Employment Opportunity Commission. Time Limits For Filing A Charge Miss that deadline and you forfeit the claim.
You can start through the EEOC’s online public portal, at one of the agency’s 53 field offices, or by calling 1-800-669-4000.10U.S. Equal Employment Opportunity Commission. How to File a Charge of Employment Discrimination The EEOC doesn’t take charges over the phone, but a representative will walk you through what to do next. Filing a charge is required before you can sue; skipping it means a court will dismiss the case.
If Your Reason Isn’t Medical
If your objection to the vaccine isn’t medical, a religious exemption under Title VII of the Civil Rights Act is a separate track. It requires a sincerely held religious belief, practice, or observance that conflicts with the vaccination requirement, and it does not cover personal, political, or philosophical opposition.6U.S. Equal Employment Opportunity Commission. What You Should Know About COVID-19 and the ADA, the Rehabilitation Act, and Other EEO Laws The same reasonable accommodation and undue hardship framework applies once a religious exemption is approved.
