Coronavirus and your immune system

The latest guidance about coronavirus

Updated on Friday 16th October

As we are now in the second wave of the pandemic, the UK Government has announced new measures to help reduce the spread of coronavirus. What these measures are will depend on what part of the country you live in. Please look at your local authority website for what is happening in your area and visit government websites for guidance on what you can and cannot do in:


The immune system is the body's defence against viruses like coronavirus (COVID-19), bacteria, and other foreign organisms or harmful chemicals. The blood and the lymphatic system are part of the immune system.

How cancer affects your immune system

Some types of cancer can affect your immune system. For example, blood cancers such as lymphoma and leukaemia.

Some cancer treatments also affect the immune system. This includes chemotherapy and immunotherapy. Radiotherapy may sometimes affect your immune system. Most people’s immune system will recover well after they have finished their treatment.

Improving your immune system

Lots of people have asked us questions about how to improve their immune system. Some of the best things you can do to make sure your immune system is working at its best is to eat well, stay hydrated, keep active and have enough rest, for example getting a good night’s sleep. 

We know the current situation is making it tougher, particularly as we need to stay at home or self-isolate. On this page you’ll find information to help you maintain a healthy lifestyle, even while staying at home.

Keeping active at home

It can be difficult to keep active when you can’t leave your home, but there are lots of great resources online to help you.

We recommend you take some time to search online and find what works for you. Here are some options to help you get started.

Preparing for treatment at home

It’s really important that you still look after your health and well-being before you start cancer treatment. This is called prehabilitation. It’s about making sure you’re as healthy as you can possibly be before starting your treatment.

The Medway Prehab

The Medway Prehab aims to get people to their optimal health before treatment, helping them cope with the challenges of their treatment as well as to recover faster. Here are there recommendations for home based exercise.

The Prehab4cancer programme helps people who have been recently diagnosed with cancer and are waiting to start their treatment.

Their home exercise guide has a whole range of different exercises to do at home as well as an exercise diary. 

They also have a dietary guide to help you eat well while preparing for treatment.

Eating well at home

Eating well and keeping to a healthy weight will help you keep up your strength, increase your energy levels and improve your sense of well-being.

We know it’s been difficult to get hold of certain foods recently. We have information about getting food while self-isolating

This diagram shows the proportion of each type of food you should try to eat for a healthy, balanced diet.

It might be useful to refer to it when you’re writing your shopping list. It could also be something you share with anyone who is helping you with your food shopping while you’re at home. 

Food group chart

Aim to eat plenty of fruit and vegetables and starchy foods. The proportion of protein you eat should be smaller. The amount of dairy you have should be smaller still. You should aim to have only a small amount of oils and spreads.

We know it can be difficult to shop and to get hold of supplies right now. Suggestions for recipes to help us make the most of everyday ingredients and store-cupboard items are emerging. Search online or ask family and friends to share recipe ideas.
