COVID-19 vaccine

The COVID-19 vaccine helps protect against COVID-19, which can be a serious or life-threatening illness. It's offered on the NHS to people at increased risk of getting seriously ill from COVID-19.

What the COVID-19 vaccine is for

COVID-19 vaccination is an important part of protecting yourself if you're at increased risk of getting seriously ill from COVID-19.

The COVID-19 vaccines are offered because viruses change and protection fades over time. It's important to top up your protection if you're eligible.

Getting the COVID-19 vaccine can:

  • help reduce your risk of getting severe symptoms
  • help you recover more quickly if you catch COVID-19
  • help reduce your risk of having to go to hospital or dying from COVID-19
  • protect against different types of COVID-19 virus
Information:

You may still get or spread COVID-19 even if you have a vaccine, so it's important to follow advice about how to avoid catching and spreading COVID-19.

Who should have the COVID-19 vaccine

The COVID-19 vaccine is recommended for people at increased risk from COVID-19.

You may be offered a COVID-19 vaccine if you:

  • are aged 65 or over
  • are pregnant
  • are aged 6 months to 64 years and have an increased risk of getting seriously ill from COVID-19 because of a health condition or treatment
  • live in a care home for older adults
  • are a frontline health or social care worker
Who’s at increased risk of getting seriously ill from COVID-19

You may be more likely to get seriously ill from COVID-19 due to a health condition, treatment or medicine, including:

  • conditions that affect your breathing, such as asthma (needing a steroid inhaler or tablets), chronic obstructive pulmonary disease (COPD) or cystic fibrosis
  • heart conditions, such as coronary heart disease or hypertension
  • chronic kidney disease
  • liver disease, such as cirrhosis or hepatitis
  • chronic digestive issues, such as severe gastro-oesophageal reflux
  • some conditions that affect your brain or nerves, such as Parkinson's disease, motor neurone disease, multiple sclerosis or cerebral palsy
  • a learning disability
  • diabetes, Addison's disease or hypopituitary syndrome
  • problems with your spleen, such as sickle cell disease, or if you've had your spleen removed
  • being very overweight – a body mass index (BMI) of 40 or above
  • severe mental health conditions, such as schizophrenia or bipolar disorder
  • some genetic disorders, such as mitochondrial disease and chromosomal conditions
  • a weakened immune system due to a condition such as HIV or AIDS, or due to a treatment such as chemotherapy or steroid medicine

This list is a summary and does not cover everything. Read a full definition in tables 3 and 4 in the COVID-19 chapter of the green book on GOV.UK.

How to get the COVID-19 vaccine

If you're eligible for the winter COVID-19 vaccine, you can:

Some people may be able to get vaccinated through a local service, such as a community pharmacy or your GP surgery, or a care home if they live in a care home.

You do not need to wait for an invitation before booking an appointment.

How the COVID-19 vaccine is given

The COVID-19 vaccine is given as an injection.

Most people only need 1 dose of the winter COVID-19 vaccine.

Extra doses of the COVID-19 vaccine

Some people need an extra dose of the COVID-19 vaccine if they have a health condition or treatment that severely weakens their immune system. For example, if they have had a stem cell transplant or CAR-T therapy.

Your GP or specialist will assess your risk and tell you if you need an extra dose of the vaccine. They will advise you on when to get vaccinated based on your treatment plan, and help you find a local appointment. Speak to your GP or specialist for more information.

If your GP or specialist cannot arrange an appointment for you, you can contact your local NHS COVID-19 vaccination service.

Find local COVID-19 vaccination contacts on the NHS England website

Information:

Having the COVID-19 vaccine at the same time as other vaccines

You can have the winter COVID-19 vaccine at the same time as the flu vaccine. If you're eligible for an RSV vaccine, it's more effective to have it on a different day to your COVID-19 and flu vaccines.

Who cannot have the COVID-19 vaccine

Most people who are eligible for the COVID-19 vaccine can have it.

Some people are only offered certain vaccines, for example, if you're under 18 years old. Children under 12 years old will be given smaller doses than older children and adults.

Most people with allergies can have the COVID-19 vaccine, including if you’ve had a mild allergic reaction to a previous dose, such as a rash, swelling, wheezing or hives.

If you've ever had an allergic reaction, tell the healthcare staff at your appointment before you're vaccinated.

If you’re at risk of a severe allergic reaction, vaccination staff or your GP may refer you to an expert allergist or specialist to assess your risk. They may advise you to have the COVID-19 vaccine at a specialist clinic or hospital where you can be monitored. This will only happen in rare cases, for example if you have a history of anaphylaxis.

Information:

Getting vaccinated if you're unwell

If you have, or think you have, COVID-19 wait until you're feeling better before having the vaccine. You should also wait if you have a high temperature or feel very unwell with any illness.

If you’ve recently recovered from COVID-19, there is no need to wait to get the vaccine.

COVID-19 vaccine ingredients

There are 2 main types of COVID-19 vaccine given in the UK.

If you're eligible for the COVID-19 vaccine on the NHS, you'll be offered a vaccine that’s appropriate for you. You cannot choose which COVID-19 vaccine you have.

The COVID-19 vaccines used by the NHS do not contain any animal products, including eggs.

Side effects of the COVID-19 vaccine

The most common side effects of the COVID-19 vaccine are mild and get better within a week.

They can include:

  • a sore arm from the injection
  • feeling tired
  • a headache
  • feeling achy
  • mild flu-like symptoms

If you or your child get side effects, rest and take paracetamol or paracetamol for children to help you feel better.

More serious side effects such as a severe allergic reaction (anaphylaxis) are very rare. The person who vaccinates you will be trained to deal with allergic reactions and treat them immediately.

There have been rare cases of inflammation of the heart (myocarditis) reported after COVID-19 vaccination. Most people who had this recovered following rest and simple treatments.

The vaccine cannot give you COVID-19 infection.

COVID-19 vaccine safety

COVID-19 vaccines in use in the UK have all met strict standards of safety, quality and effectiveness. The safety of the vaccines has been extensively reviewed in both adults and children by the independent Medicines and Healthcare products Regulatory Agency (MHRA).

The MHRA are continuously monitoring the safety of the COVID-19 vaccines and reports of serious side effects are very rare.
