About the vaccine




Coronavirus (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus. Most people infected with the virus will have mild to moderate respiratory illness and recover without needing special treatment. However, some people can become seriously ill and need medical attention.  

Older people and those with underlying medical conditions such as cardiovascular disease, diabetes, cancer or chronic respiratory disease are more likely to develop serious illness.  

Symptoms of COVID-19 include a new, continuous cough, a loss or change to your sense of smell or taste, aches and pains, a headache, tiredness and weakness. More information about COVID-19 is available from NHS 111 Wales - Health A-Z : Coronavirus (COVID-19) (external site)

About the vaccine

COVID-19 vaccines help protect against the current main types of COVID-19 viruses. 

The Medicines and Healthcare products Regulatory Agency (MHRA) are responsible for approving the use of medicines, including vaccines, and monitoring their safety. They have approved a number of vaccines for use in the UK as safe and effective COVID-19 vaccines.  

You can report any side effects through the MHRA Coronavirus Yellow Card page.  

In Wales, we follow advice from the Joint Committee on Vaccination and Immunisation (JCVI) on the use of different vaccine products as part of the COVID-19 vaccination programme. 

You can find answers to frequently asked questions about the COVID-19 vaccine below. We will update this page regularly, when new information is available.
