The UK has become the first country in the world to approve a vaccine for use in the fight against the coronavirus pandemic.
The government has now published further information on the vaccine, developed by US firm Pfizer, ahead of its roll-out next week.
The information for vaccine recipients includes a list of possible side effects, specific advice for vulnerable groups, and further information on how it works and what it contains.
It says the vaccine is used "for active immunisation to prevent Covid-19 disease caused by SARS-CoV-2 virus" and is suitable for adults and children aged 16 and over.

There is currently limited data available on the use of the vaccine in pregnant women.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, you should ask your doctor or pharmacist for advice before getting vaccinated.
