Will the COVID-19 vaccine be suitable for me?

The approved COVID-19 vaccines are suitable for people who have had a stem cell transplant or who are waiting to have a stem cell transplant. This is because these vaccines are not 'live' vaccines.

These vaccines are currently approved for use in the UK by the Medicines and Health Regulatory Agency (MHRA):

• Pfizer/BioNTech (Comirnaty)*
• Moderna (Spikevax)*
• Novavax (Nuvaxovid)
• Sanofi/GSK (VidPrevtyn Beta)

The Novavax (Nuvaxovid) vaccine is available for those who cannot have the other types of vaccine, for example due to allergies.

The Sanofi/GSK (VidPrevtyn Beta) vaccine is primarily used for people aged over 75. It contains animal product, so it is not appropriate for some religious groups.

How many vaccines do I need?

People who have had, or are going through, a stem cell transplant or CAR T-cell therapy are immunosuppressed and at higher risk of severe illness from COVID-19. This means that it is recommended you have extra vaccine doses compared to the general public. It is recommended that:

• people aged 12 and above should have two primary doses after their treatment followed by additional seasonal doses.
• children aged 6 months to 11 years should have two primary doses at a reduced dose after their treatment followed by additional seasonal doses.

When should I be vaccinated?

The COVID-19 vaccines are given as multiple injections, a number of weeks apart. This is the recommended vaccine schedule for anyone who has had a stem cell transplant or CAR T-cell therapy:

1. First dose three to six months after your transplant or CAR T-cell therapy.
2. Second dose at least three weeks after your first dose.
3. Additional doses (previously called 'boosters') at least three months after your second dose. All following doses will be three to six months apart, as part of national seasonal vaccination campaigns.

This schedule is recommended by the British Society of Blood and Marrow Transplantation and Cellular Therapy (BSBMTCT).

If you have not been offered COVID-19 vaccination and feel you are eligible, we recommend you contact your medical team or GP.

In England, if your medical team or GP is unsure where you can receive your COVID-19 vaccination, your local Integrated Care Board (ICB) can tell you the closest vaccination site. The contact details of your local ICB are on this webpage.

Your medical team knows your individual situation best and will make sure you are vaccinated at the best time. This may be different from the above schedule.

How soon after my treatment can I be vaccinated?

The COVID-19 vaccine is more likely to be effective if you have a functioning immune system. This means that people who have just had their stem cell transplant or CAR T-cell therapy may need to wait a few months before they can be vaccinated.

The British Society of Blood and Marrow Transplantation and Cellular Therapy (BSBMTCT) recommends: 

• Anyone who has had a stem cell transplant receives their first vaccine three to six months after treatment. 
• Anyone who has had CAR T-cell therapy receives their first vaccine six months or later after treatment. 

More details can be found in the BSBMTCT’s COVID-19 vaccination guidance.

If you were vaccinated before your transplant or CAR T-cell therapy, you should be re-vaccinated with a full course after transplant. Read more about re-vaccination below.

Anyone who is experiencing graft versus host disease (GvHD) after their transplant or CAR T-cell therapy may have their vaccination temporarily delayed to make sure they have the strongest response from their immune system.

Side effects

After receiving the COVID-19 vaccine it may feel sore where the needle went into your arm, or you may feel tired or sick, have a headache or body aches. These common side effects usually wear off within 48 hours. If you experience any other side effects, or they last longer than 48 hours, we recommend you discuss them with your GP or hospital team.

The COVID-19 vaccines could cause side effects in a few people with allergies to the components of the vaccine. If you have concerns that your own allergies may affect your reaction to the vaccine, you should talk to the medical team about it beforehand. Providing a list of the medications you are currently taking would also be helpful.

There is no evidence that people with blood cancer are at an increased risk of side effects after COVID-19 vaccination than the general population. Blood Cancer UK's Healthcare Professional Advisory Panel released an updated statement on COVID-19 side effects in May 2024.

Will the vaccines protect me from COVID-19?

A great deal of research is taking place into this, and Anthony Nolan is part of Blood Cancer UK’s Vaccine Task Force which is tracking all research in this area. Research progress is updated regularly on its COVID vaccine efficacy and blood cancer page.

Early findings suggest that COVID-19 vaccines may be less effective among patients who are undergoing cancer treatment, and that it may take longer for them to develop immunity.

If you are concerned about the level of protection a COVID-19 vaccine has given you, we recommend you discuss this with your healthcare team. They may be able to offer you an antibody test which can help indicate how much protection you currently have from COVID-19. They will also be able to advise you on further steps you can take to protect yourself.

A major study is taking place to discover whether lower antibody levels can accurately predict the risk of COVID-19 infection in patients who are clinically vulnerable. The two-year Stravinsky study is funded by the National Institute for Health and Care Research, and will be run at 11 sites including hospitals in Birmingham, Cardiff, Glasgow and London.

It is currently recruiting 2,600 patient volunteers, including people who have had a stem cell transplant. Find out more and volunteer to take part in the Stravinsky study.

How do the vaccines work?

Once injected, these vaccines stimulate our cells to make proteins found only in the strain of coronavirus that causes COVID-19. This does not mean we get COVID-19, but it does trigger our immune system to react to the new protein and develop immunity. So if we then get infected, our body will recognise the virus and will be able to destroy it, without us getting as ill.

Will I be prioritised for a vaccine?

People who have had or are going through a stem cell transplant are named as high risk of severe illness from COVID-19. This means that you'll be prioritised for COVID-19 vaccines, including boosters.

Vaccination centres should also make sure that waiting times are reduced for anyone who is at high risk.

If you feel you have not been appropriately prioritised for a vaccine, your GP or medical team will be able to address this on your behalf.

You may find the following official statements useful when having your discussion:

• BSBMTCT (British Society of Blood & Marrow Transplantation & Cellular Therapy) COVID-19 Vaccination Statement
• British Society for Immunology statement on COVID-19 vaccines for patients who are immunocompromised or immunosuppressed

COVID-19 vaccines are now also available to buy privately. Household contacts of immunosuppressed people may choose to access vaccination in this way. If you are interested in this option, please speak to your GP. You may also find additional information online.

Will my other medications or treatments impact how effective the vaccine is?

For the vaccine to work effectively, your body needs a functioning immune system so that it can react to the vaccine and provide immunity.

Treatments such as systemic steroids and immunosuppressant drugs (such as Ciclosporin and ECP), usually given to prevent or treat graft versus host disease (GvHD), are all designed to suppress your immune system. This means they could potentially reduce your body’s response to the vaccine.

As post-transplant patients continue to receive COVID-19 vaccines, it will be important to understand how well they respond to the different types of vaccine, to inform future recommendations. As soon as we have a better understanding from the experts we work with, we will update this information.

Will I need to be vaccinated again after my transplant?

Yes. During your transplant your immune system is replaced, so if you received any COVID-19 vaccines before your transplant it is recommended that you are vaccinated again after your transplant. This is known as re-vaccination. If you have had CAR T-cell therapy, you will also need to be re-vaccinated.

Your COVID-19 re-vaccination will not interfere with your childhood re-vaccination schedule.

All doses of COVID-19 vaccine, delivered at regular intervals, will be required after your transplant to give you maximum protection. The NHS currently offers two primary doses and seasonal booster doses of COVID-19 vaccine to stem cell transplant and CAR T-cell therapy recipients.

Your transplant team will help to arrange this for you. They will assess your individual situation to make sure you are re-vaccinated at the most suitable time for you.

Your transplant team should use this letter template (also known as a Patient Specific Direction Form) to inform your GP that you need to be re-vaccinated after your transplant. This template has been provided by NHS England.

This official recommendation for patients to be re-vaccinated after stem cell transplant is in the Public Health England guidance for healthcare professionals known as the Green Book. The reference to re-vaccination is in Chapter 14a on page 33. You may find this useful when discussing re-vaccination with your transplant team.

If your GP is unable to obtain the vaccination doses you require, ask your transplant team to contact your local NHS vaccination service (also known as an Integrated Care Board) directly. Find their contact details on the NHS website.

What else can I do to stay protected?

Even if your current situation suggests you may not have a strong response to the vaccine, it is still important for you to have the vaccine because even some protection is better than none.

After vaccination it can take some time to develop an immune response to COVID-19, and the level of protection for stem cell transplant recipients is not yet fully understood. So when you have had your vaccine, you should still remain careful and maintain the measures you have been following to protect yourself during the pandemic. This includes wearing a face mask, maintaining social distancing and regularly washing your hands.

This is particularly important when COVID-19 cases are high.

Treatment

The following treatments are suitable for people at high risk of COVID-19:

• Nirmatrelvir and ritonavir (Paxlovid)*
• Sotrovimab (Xevudy)
• Tocilizumab (RoActemra, Roche Products)
• Molnupiravir (Lagevrio)*
• Remdesivir (Veklury)*
• Tixagevimab and cilgavimab (Evusheld)**
• How do I access these treatments?
• How can I support research into COVID-19 treatment for stem cell transplant patients?

*under review

**not available from the NHS in the UK

Some high risk patients (previously called 'clinically extremely vulnerable') who test positive for COVID-19 may be offered treatment at home or in the community to help stop severe illness. These high risk patients include those who:

• have had a stem cell transplant in the last 12 months
• have had a stem cell transplant at any time and have GvHD
• have had CAR T-cell therapy in the last 24 months
• have sickle cell disease
• are being treated, or have recently completed treatment, for a blood cancer
• have a non-malignant haematological disorder (such as aplastic anaemia and paroxysmal nocturnal haemoglobinuria) and have had certain treatments that affect B-cells within the last 12 months
• have had chemotherapy or radiotherapy in the last 12 months.

Antiviral and antibody treatments help to prevent hospitalisation and serious illness in those most at risk. They are especially important for those who have compromised immune systems.

How do I access these treatments?

The full process is explained here for:

• England
• Wales
• Scotland
• Northern Ireland

If you test positive for COVID-19, you will need to either:

• contact your medical team
• contact your GP
• call 111 (999 in an emergency)

You will then be assessed for treatment. A medical professional will choose which treatment is most appropriate for you.

In England, access to treatment changed on 27 June 2023. You should have received a letter in the post explaining these changes. Read an example letter. If you didn't receive a letter, don't panic. You can still access treatment if needed.

In Wales, from 1 February 2024 you will need to use this form to report a positive COVID-19 test result.

Nirmatrelvir and ritonavir (Paxlovid)

Nirmatrelvir and ritonavir make up the antiviral medicine Paxlovid and is a first-line treatment.

This treatment is in the form of tablets you swallow and can be taken at home. If you are prescribed Paxlovid, it can be delivered to your home or someone can collect it for you.

You should start taking Paxlovid within five days of starting to experience COVID-19 symptoms. The recommended dose is two tablets of nirmatrelvir and one tablet of ritonavir twice a day, morning and evening. You should take the three tablets at the same time, and should swallow them whole. You can take them with or without meals. This course of treatment lasts for five days.

Paxlovid is not suitable for people with certain health conditions, or those taking certain medications. This will be discussed with you before you are prescribed medication for COVID-19.

If you're not a part of the high risk category, you can still access Paxlovid as part of a national trial called PANORAMIC. Eligible patients - those over 50 or with underlying health conditions - will be contacted by the study team or a healthcare professional (e.g. GP or research nurse) after receiving their positive test result to discuss the option of taking part. Not all trial participants will be offered Paxlovid. You can find out more at: panoramictrial.org

Sotrovimab (Xevudy)

Sotrovimab (also known as Xevudy) is a monoclonal antibody therapy given to patients through a drip in their arm.

It is only prescribed to patients if other COVID-19 treatments have been deemed unsuitable for them.

If sotrovimab is prescribed, you will be able to access it in community settings, like a local hospital or healthcare centre, and it will be given to you by a doctor or nurse. You may also be able to access this treatment if you are hospitalised with COVID-19 and at high risk of severe illness.

Another antibody treatment called Ronapreve has also been made available, both in and out of hospital. It is not being widely used as it is less effective against circulating variants.

Molnupiravir (Lagevrio)

Molnupiravir (also known as Lagevrio), an antiviral treatment, is in the form of a capsule you swallow and can be taken at home. This is a third-line treatment.

If you are prescribed molnupiravir, this can be delivered to your home or someone can collect it for you.

You should start taking molnupiravir within 5 days of starting to experience COVID-19 symptoms. The recommended dose is four 200mg capsules, every 12 hours for 5 days.

Starting molnupiravir today. Apart from a little hiccup, the new scheme for high risk people in regards to priority PCR and antiviral medication is amazing, fast and efficient.

Remdesivir (Veklury)

Remdesivir (also known as Veklury) is an antiviral medicine given to patients through a drip in their arm. This is a second-line treatment.

If remdesivir is prescribed, you will be able to access it in community settings, like a local hospital or healthcare centre, and it will be given to you by a doctor or nurse. You may also be able to access this treatment if you are hospitalised with COVID-19 and at high risk of severe illness.

Tixagevimab and cilgavimab (Evusheld)

Evusheld is made up of two long-lasting antibodies called tixagevimab and cilgavimab. It is a preventative treatment and should protect you against COVID-19 for up to 6 months.

This treatment is for people who are unlikely to have developed a good immune response from the COVID-19 vaccinations, or are unable to have the vaccines at all.

However, NICE (National Institute for Health and Care Excellence) said in February 2023 that there is not enough evidence to show that Evusheld is effective against currently circulating COVID-19 variants. You can read more about this decision on their website.

Therefore, Evusheld is not available from the NHS in the UK. Despite NICE’s guidance, Evusheld is available privately. With little protection against new variants, we strongly recommend consulting the advice of a clinician before accessing treatment.

Anthony Nolan is campaigning with other charities and clinicians to urge the government to commit to rolling out alternative protective treatments for our patients as they become available.

How can I access lateral flow tests?

It's important to have lateral flow tests at home so you can use one immediately if you need to.

People at high risk of severe illness from COVID-19 can get free lateral flow tests.

In England, Wales and Northern Ireland free lateral flow tests are available from community pharmacies only. It is likely you will need to provide the pharmacy with the following details:

• Your medical condition confirming your eligibility.
• Your NHS number (if you have it).
• Your full name, date of birth and address.

Someone else can collect free lateral flow tests on your behalf. They will need to give the details above to the pharmacist.

In England you can use Find a pharmacy to check if a pharmacy offers free lateral flow tests. Click on a pharmacy name - if it offers free COVID-19 lateral flow tests, this will be listed in its 'Treatments and services' section under 'Screening and test services'.

In Scotland you can request free lateral flow tests online using the NHS Scotland portal.

In Wales you can collect lateral flow tests from community pharmacies only. Use this NHS 111 Wales webpage to search for your nearest community pharmacy.

It’s important to understand what to do if you are considered high risk and test positive for COVID-19, so you can be treated as soon as possible.

• If you have any difficulty obtaining this treatment, or if you need to confirm your eligibility, contact your GP or medical team as soon as possible.

• If you are classed as high risk and are admitted to hospital with COVID-19, make sure that doctors are aware so you may be considered for these treatments.

You can find out more about the latest antibody and antiviral treatment developments, including how these treatments work, on the Blood Cancer UK website.

How can I support research into COVID-19 treatment for stem cell transplant patients?

Pharmaceutical company AstraZeneca is recruiting people with weakened immune systems, including stem cell transplant patients, to take part in its ongoing Supernova study.

The study is investigating whether a drug (known as a pre-exposure prophylactic) can help protect people with weakened immune systems from contracting COVID-19.

Further details, including trial locations and contact details, are available on the Supernova trial website.

Shielding

• Should I still be shielding?
• Keeping yourself safe

Should I still be shielding?

As an adult you are at very high risk of severe illness from COVID-19 if you:

• are currently being treated for a blood cancer or blood disorder
• had a stem cell transplant within the last 12 months
• are taking medication to suppress your immune system, including treatment for graft versus host disease (GvHD).

If you fall into this high risk (previously called 'clinically extremely vulnerable') category, you were previously advised to follow ‘shielding’ measures to keep yourself safe from COVID-19. Shielding advice has now been withdrawn. Instead, anyone at high risk is advised to discuss the precautions you follow with your own medical team.

Each government has published advice for anyone at high risk in:

• England
• Wales
• Scotland
• Northern Ireland

If your child had a stem cell transplant, their medical team will advise you whether they are at very high risk of severe illness from COVID-19. You can read further guidance for parents on the British Society of Blood and Marrow Transplantation and Cellular Therapy (BSBMTCT) website.

Keeping yourself safe

In England, the government has specific guidance for people whose weakened immune system means they are at higher risk. You are advised to:

• make sure you have had all the vaccines you are eligible to receive, including boosters
• continue to follow any condition-specific advice you may have been given by your medical team
• avoid meeting with someone who has tested positive for COVID-19 for 10 days after their positive result
• avoid meeting people who have any symptoms of COVID-19 or other respiratory infections
• work from home if you can – if you cannot work from home, speak to your employer about what temporary arrangements they can make to reduce your risk
• wait until 14 days after another person’s most recent dose of a COVID-19 vaccine before being in close contact with them
• avoid enclosed crowded spaces
• practise social distancing if that feels right for you
• ventilate your home by opening windows and doors to let fresh air in
• ask friends and family to take a rapid lateral flow antigen test before visiting you
• ask home visitors to wear face coverings
• wash your hands regularly and avoid touching your face.

We recommend that you discuss your situation with your own medical team before making any changes to the precautions you follow.

Your team has the fullest understanding of your own medical history and the potential impact COVID-19 could have on your health.

Blood Cancer UK offers 'Please stand back, I'm shielding' badges for a postage fee and voluntary donation, which you may find helpful.

My stem cell transplant

• How will my treatment be affected?
• Will my stem cell transplant still go ahead?

How will my treatment be affected?

Your transplant team are likely to change how they manage your medical appointments. Some consultations will be carried out either over the phone or by video. This will limit the amount of face-to-face contact needed and reduce your need to travel on public transport.

If you do need to attend in person, steps will be put in place to reduce the time spent in waiting rooms. Everyone will be asked to attend appointments without family members or carers if possible.

Where possible you should also try to avoid picking up your prescriptions in person. This can be done by ordering through online home delivery services, asking for help from family and friends or NHS volunteer services.

Will my stem cell transplant still go ahead?

The stem cell transplant process significantly weakens the immune system, making patients more vulnerable to contracting infections including COVID-19. During the first peak of the COVID-19 outbreak, some stem cell transplants were delayed to help protect patients and enable vital NHS resources to be directed to where they were most needed.

Most autologous transplants and allogeneic transplants where the situation was deemed non-urgent were affected.

Despite the current level of COVID-19 infections, hospitals are currently able to cope with the demands of treating patients. We keep in regular contact with all the UK’s transplant centres and continuously monitor the situation.

At Anthony Nolan, we are working closely with every transplant centre in the UK and our suppliers to minimise the disruption COVID-19 may cause.

Where possible, we are searching for multiple potential stem cell donors, including those from umbilical cord stem cells, and making sure we can still import donated cells from across the world. This will allow us to continue our lifesaving work.

If you have any specific concerns, please contact your transplant centre. They will be in the best position to advise based on your medical condition, where your stem cells are coming from and the impact of COVID-19 on local hospitals.

More information about COVID-19 and how to reduce the risk of infection is available from the NHS website.
