Very happy, I ordered my Medical Certificate in the early morning hours and before noon time of same day I had it on my inbox. Speedy service and they present the health condition precisely, get to the point.
They meet the incredibly fast turnaround stated (certificate/letter sent before 9am the following morning if the doctor feels that a letter/certificate is appropriate) which is incredibly quick and I am really grateful for the help provided!
Very easy and quick to get my certificate. And the certificate was approved from the specific company to travel with my dog. I will use them again. Well done.
Second time using this company and they are fabulous! Always great, fast, friendly service. Highly recommend!
This was my second time using Medical Cert, and once again the service was exceptionally quick and professional. Everything was handled efficiently, with clear communication throughout.
I found the service very straight forward and quick. Exactly what I needed to get my Padi medical form signed before our holiday. Thank you very much.
Second year running where requested Sports Certificate has been produced promptly in advised timescales.
Process was easy and responses were quick. I would recommend their service.
Fast efficient service for medical certificates. I used the not fit to fly service and was provided with a certificate the next day, the price is very reasonable and enabled a flight credit refund with my airline. Would recommend and would use again if needed.
A fast and efficient service. It wasn't complicated and the Fit-to-fly note was accepted by the Airport without any further questions. Thank you.
Ideal for me, I am looking to get a certificate for some medical issues I have. So this is the perfect solution for me, uploading docs was easy and the forms very straightforward to fill in. Will definitely use them again. Many thanks.
Excellent service. Easy to use and certificate issued in less than 24 hours. £39 as opposed to the £150 my GP charges. Highly recommended.
Quick and reasonably pain-free. Received their standard certificate as well as my requested bespoke certificate, by email, by 9am the following morning. Both completed properly, signed and stamped as required. More expensive than my GP, but infinitely quicker and easier.
One of the best experiences. It's easy to get a GP note.
Excellent. My GP refuses to issue DWP MED 3 Fit Notes to students. MedicalCert were excellent and extremely helpful in providing a necessary certificate. Highly recommended.
You were amazing, you kept me updated and replied promptly to any queries I had. I thank you from the bottom of my heart.
They helped me, they were very professional and nice.
Very pleased. Quick service with very professional letter provided.
Great service, pretty straight forward and easy to use the website.
I was recommended Medical Cert by a friend and was so impressed with the service received. I would recommend using a laptop rather than a phone. Overall a fantastic and fast service.
A vaccine medical exemption certificate is a doctor-signed document confirming that you have a genuine medical contraindication to a specific vaccine. It is used to demonstrate medical grounds for non-vaccination to employers, travel authorities, entry requirements, or other organisations that would otherwise require proof of vaccination. This guide explains the accepted medical grounds for exemption, which vaccines this applies to, and how to obtain a certificate online, subject to clinical review by a GMC-registered doctor.
Vaccine exemption certificates are issued only where there is a legitimate clinical reason — such as a known allergy to a vaccine component, a prior serious adverse reaction, or an immune condition that makes vaccination unsafe. Exemptions are not available on personal, philosophical, or religious grounds. The certificate reflects a medical assessment based on the information and evidence you provide.
Vaccines for Which Medical Exemptions May Be Available
Yellow Fever
- Required for entry to many countries in Africa and South America
- Medical exemption available where contraindication exists
- See our dedicated Yellow Fever Exemption Certificate page for full details
Influenza (Flu) Vaccine
- Required by some healthcare employers as a condition of deployment
- Medical exemption relevant where severe egg allergy or prior anaphylaxis exists
- Evidence of contraindication required
Meningitis & Other Travel Vaccines
- Meningococcal vaccination required for Hajj and Umrah pilgrimage by Saudi authorities
- Other travel vaccines (e.g. hepatitis A, typhoid) where allergies to components exist
- Entry requirement exemptions for specific destination countries
MedicalCert only issues vaccine exemption certificates where there is a genuine medical contraindication — a clinical reason why the vaccine cannot safely be administered. Exemptions cannot be issued on the basis of personal preference, hesitancy, or religious beliefs. The reviewing doctor will only issue a certificate where the medical evidence clearly supports an exemption.
Accepted Medical Contraindications for Vaccine Exemption
The following are recognised medical grounds for vaccine exemption in the UK, subject to clinical review of the specific circumstances and evidence provided:
Allergy & Hypersensitivity
- Known allergy to a vaccine component — including egg (relevant for flu and yellow fever vaccines), gelatin, latex, or specific preservatives
- History of anaphylaxis following a previous dose of the same or closely related vaccine
- Documented severe allergic reaction to a vaccine excipient
Immune Conditions & Medical Contraindications
- Severe immunocompromise — relevant for live vaccines (yellow fever, MMR)
- Thymus gland disorders or removal (thymectomy) — relevant for yellow fever
- Active cancer treatment with immunosuppressive therapy
- HIV with severely reduced CD4 count
- Family history of severe adverse reaction — relevant for yellow fever in some circumstances
- Age-based risk — some vaccines have higher risk profiles for older adults (e.g. yellow fever in over-60s)
What a Vaccine Medical Exemption Certificate Includes
A vaccine exemption certificate from a GMC-registered doctor, subject to clinical review, will confirm:
- Your full name and date of birth
- The specific vaccine for which exemption is granted
- The medical reason for exemption, at an appropriate level of clinical detail
- A clear statement that you have a medical contraindication to the vaccine
- The date of issue and the reviewing doctor’s GMC registration details
- A unique QR-coded verification reference
The certificate is accepted by most UK employers, travel authorities, and international organisations that recognise medical exemptions. Acceptance by specific authorities — particularly for international entry requirements — is not guaranteed and should be confirmed with the relevant body before travel.
How to Get a Vaccine Medical Exemption Certificate Online
Gather your medical evidence
Collect documentation confirming your contraindication — such as allergy test results, a specialist letter confirming immunosuppression, prescription records for immunosuppressive medication, or records of a previous adverse vaccine reaction. Without verifiable evidence, a certificate cannot be issued.
Complete the online consultation form
Provide your medical history, the specific vaccine for which you are requesting exemption, the clinical reason, and upload your supporting evidence. If the requesting organisation has a specific form, upload it at this stage.
GMC-registered doctor review
A GMC-registered doctor reviews your submission and supporting evidence. Where the evidence clearly supports a medical contraindication, a signed exemption certificate is issued. If evidence is insufficient, the certificate will not be issued and a refund will be provided.
Receive your certificate by email
Your certificate is delivered as a PDF with a unique QR verification code — same day or by 9AM the following morning. Present it to your employer, travel authority, or other requesting organisation.

Can I get a vaccine exemption for religious or personal reasons?
No. MedicalCert only issues vaccine exemption certificates where a genuine medical contraindication exists — a clinical reason why the vaccine cannot safely be given. Exemptions on the basis of personal preference, hesitancy, or religious conviction are not available through this service or through any legitimate UK medical provider.
What evidence do I need to provide?
The evidence required depends on the reason for exemption. For allergy-based exemptions, allergy test results or a specialist letter confirming the allergy are ideal. For immunosuppression-based exemptions, letters from your oncologist or specialist, or a prescription record for immunosuppressive medication, are typically sufficient. For age-based yellow fever exemptions, passport confirmation of age is generally sufficient. Without verifiable evidence, the certificate cannot be issued.
Will my exemption certificate be accepted internationally?
Most countries that accept medical vaccine exemptions will accept a certificate signed by a GMC-registered UK doctor. However, acceptance is at the discretion of the receiving authority — border officials, airline staff, or local health authorities — and is not guaranteed. Always check the current requirements with the relevant embassy or authority before travel, as policies can change.
How long is a vaccine exemption certificate valid?
MedicalCert vaccine exemption certificates are issued with a 12-month validity period from the date of issue. This reflects the period during which the clinical basis for exemption has been reviewed. Some organisations may require a more recently issued certificate — always check validity requirements with the specific authority.
Can I get an exemption if I have had a severe reaction to a previous vaccine?
Yes, subject to clinical review. A documented history of anaphylaxis or severe systemic reaction to a previous dose of the same vaccine, or to a closely related product, is a recognised contraindication. Evidence of the adverse reaction — such as a hospital discharge letter or allergy assessment — should be provided to support the application.
