Vaccination schedule for CLL patients | CION Cancer Clinics
Most people with CLL are advised to have the yearly injected flu vaccine, the pneumonia vaccine, COVID-19 vaccines and the non-live shingles vaccine. Live vaccines are generally avoided. Vaccines work better at diagnosis or before treatment starts. This page explains each vaccine, the timing around treatment, how family can help, and why your own schedule must come from your haematologist. At CION Cancer Clinics, every leukaemia, MDS and MPN case is reviewed by our haematologist and discussed at a tumour board before a plan is agreed.

The short answer
Which vaccines should a person with CLL have?
Most people with CLL are advised to have the yearly flu vaccine, the pneumonia vaccine, COVID-19 vaccines and the non-live shingles vaccine. Live vaccines are generally avoided. Timing matters, because vaccines work better before treatment starts.
Why vaccines matter more in CLL
CLL weakens the immune system, even when no treatment is needed. Chest infections, flu and shingles are more common and can become serious faster. Vaccines are one of the simplest ways to lower that risk, and they are part of good CLL care from the day of diagnosis.
Why they may work less well
Vaccines work by teaching your immune system to make antibodies. In CLL, the cells that make antibodies often do not work properly, so the response can be weaker than in a healthy person. Some treatments weaken it further. A partial response still gives useful protection, which is why vaccines are still advised.
Why live vaccines are different
A live vaccine contains a weakened form of the germ. In a healthy person, the immune system controls it easily. In CLL, especially during treatment, that weakened germ can occasionally cause the illness itself. That is why your haematologist will check the type of every vaccine before you have it.
Always tell the person giving any vaccine that you have CLL, and name any treatment you are on.The usual list
What does each recommended vaccine protect against?
Your own list depends on your age, treatment and past vaccines. These are the ones haematologists most often advise.
Flu vaccine
The injected flu vaccine, every year. Flu can lead to pneumonia in people with CLL. The nasal spray version is live and is avoided. Ask for the current season's vaccine, since the strains change.
Pneumonia vaccine
Protects against pneumococcus, a common cause of serious chest infections and blood infections. Some schedules use more than one type of pneumonia vaccine.
COVID-19 vaccines
People with CLL may be offered extra or booster doses. Ask your team what current guidance recommends.
Shingles vaccine
The non-live, recombinant shingles vaccine is the one usually advised. The older live shingles vaccine is avoided. Shingles is common in CLL and can leave long-lasting nerve pain, so this vaccine is worth asking about early.
Others, depending on you
Your doctor may also discuss a few more.
- Hepatitis B, if you are at risk or not immune
- Tetanus and diphtheria boosters
- Non-live travel vaccines

Getting the timing right
When should vaccines be given around CLL treatment?
-
At diagnosis, or during watch and wait
This is usually the ideal time to catch up. The immune system has not yet been weakened by treatment, so the response is as strong as it is likely to be. Many people are told they have CLL and then hear nothing about vaccines, so raise it yourself at the first visit.
-
Before treatment starts
If treatment is planned, your team may suggest vaccines a couple of weeks beforehand where possible. Treatment should not be delayed for long just to fit vaccines in.
-
During treatment
Non-live vaccines such as flu can still be given, but the response is weaker. Antibody drips such as rituximab and obinutuzumab dampen it most. Live vaccines are not given during treatment.
-
After antibody treatment
Response usually recovers slowly over several months. Your team may repeat some vaccines once it has.
-
Every year
Review your vaccines at a routine visit, and have the flu vaccine before the flu season.

Commonly believed
What do families get wrong about vaccines and CLL?
"Vaccines will make the CLL worse."
There is no good evidence that non-live vaccines make CLL progress. The risk from flu, pneumonia or shingles is far greater than the risk from the vaccine.
"If they may not work fully, there is no point."
Partial protection can still turn a dangerous infection into a milder one. Combined with hand washing and early care for fever, it adds up to real protection. Vaccinating the people you live with adds another layer, because they are less likely to bring the infection home.
"I had the shingles vaccine years ago, so I am covered."
If it was the older live vaccine, it may not protect well now, and it should not be repeated. Ask whether the non-live vaccine is advised for you.
"Once I am vaccinated, I can stop being careful."
A vaccinated person with CLL can still catch these infections. Keep acting quickly on a fever, and avoid close contact with people who are ill. Vaccines lower the risk. They do not remove it, and the everyday habits still matter just as much.
Around you
How can the family help protect you?
- Everyone at home has the yearly flu vaccine
- Adults keep COVID-19 vaccines up to date
- Children get all routine vaccines on time
- Wash hands after changing a recently vaccinated baby's nappy
- Visitors with fever, cough or chickenpox stay away
- Someone keeps a written record of your vaccine dates
Being straight with you
Who should wait or skip a vaccine, and what can this page not tell you?
A vaccine may be delayed if you have a fever or are unwell on the day, are in the middle of an intense part of treatment, or have recently had an antibody drip. People who had a severe allergic reaction to a vaccine before should not repeat it without specialist advice.
What this page cannot tell you
It cannot give you a personal schedule. The right vaccines and timing depend on your age, earlier vaccines, current treatment, antibody levels and local availability. Guidance also changes as new vaccines are approved, so what suited someone else a few years ago may not suit you today.
How to get this sorted
Bring any vaccine records you have to your haematology visit, even old ones. Ask your haematologist to write down which vaccines you need and when. Your family doctor or a vaccination clinic can often give them, as long as they have that written plan.
If you live outside Hyderabad
You do not need to travel to a cancer centre for most vaccines. A district hospital, a government vaccination centre or a private clinic near you can usually give them. Carry your haematologist's written list, ask them to confirm the vaccine is non-live before injecting it, and keep the vaccine card or receipt so the date and type go into your records.
Questions we are asked
Common questions about vaccines for CLL
Is it safe for someone with CLL to take vaccines?
Non-live vaccines are considered safe in CLL and are usually recommended. Live vaccines are generally avoided because the weakened germ can cause illness in a weakened immune system. Always check the vaccine type with your haematologist first.
Can I get vaccines while on ibrutinib or venetoclax?
Non-live vaccines can usually be given, although the response may be weaker on these medicines. Do not stop or pause your CLL tablets to have a vaccine. Your haematologist will advise on timing if any adjustment is needed.
How long after rituximab or obinutuzumab should I wait?
These antibody drips blunt the vaccine response most, and recovery takes several months. Your team may give flu vaccine anyway during the season and repeat important vaccines later. Ask for your own timing rather than following a general rule.
Should my blood be tested to see if the vaccine worked?
This is not routine for most vaccines. In some situations, such as repeated infections, your haematologist may check antibody levels to certain vaccines. A test that shows a weak response can help decide whether extra protection is needed.
Can I have the flu vaccine every year?
Yes, the injected flu vaccine is usually advised every year, because flu strains change. Try to have it before the main flu season. Avoid the nasal spray flu vaccine, which is live.
Is the shingles vaccine available in India?
The non-live shingles vaccine has become available in India, though supply and price vary. Ask your haematologist or a vaccination clinic about current availability. If it is not available near you, ask what other steps can lower your shingles risk.
Are vaccines covered by Aarogyasri or insurance?
Adult vaccines are often not covered, but rules differ by scheme and policy and change over time. Check the current terms of Aarogyasri, CGHS, ECHS, EHS, PM-JAY or your insurer. Some government programmes offer certain vaccines free.
Can I travel abroad if I cannot have live vaccines?
Often yes, but some destinations require yellow fever vaccination, which is live. Speak to your haematologist well before booking. A medical exemption letter may be possible, but you would still carry the risk of infection there.
