Frequently asked questions

  • Where should I go for my vaccination?

    You will be told at the time of booking which vaccination centre to come to for your vaccine. We have a number of vaccination centres on both our hospital sites. Please check your text message confirmation for details of which vaccination centre you need to attend.

    St Thomas' vaccination centres 1, 2 and 3 are at our St Thomas' site. Guy's Atrium and London Bridge vaccination centres 1, 2 and 3 are at our Guy's site. Please refer to the maps for details:

  • What should I do if I have been invited to book a vaccine at Guy’s and St Thomas’ but have already had / been offered a vaccination elsewhere?

    If you have had or been offered your vaccine elsewhere, you don’t need to reply to our invite. You also do not need to reply to our invite if you want to wait to be vaccinated more locally. You will not miss out.

  • Can I choose which vaccine I receive?

    You cannot usually choose which vaccine you have. When you book, you'll only be offered appointments for vaccines that are suitable for you.

    Most people can have any of the COVID-19 vaccines, but some people are only offered certain vaccines based on medical suitability.

    For example:

    • if you're pregnant or under 40 you'll usually be offered appointments for the Pfizer/BioNTech or Moderna vaccines
    • if you're under 18, or coming for your booster dose you'll only be offered the Pfizer/BioNTech vaccine

    When you come for your appointment, we will ask you questions about your relevant medical history. This will tell us whether you are medically suitable for the vaccine you have been booked for. If because of your medical history you are not suitable for that vaccine, we will offer you an alternative vaccine. 

    It is not possible for this screening to take place online because of the nature of the screening questions, and because we need to make sure we get your full details.

  • When will my second appointment take place? 

    2nd doses are booked around 8 weeks after the 1st dose.

    The Joint Committee on Vaccination and Immunisation (JCVI) has said that the 1st dose of the vaccine provides a high level of protection but the 2nd dose is still important to provide longer lasting protection.

    Appointments for both doses are booked at the same time, however in certain circumstances we may need to rearrange your 2nd dose appointment. You will be contacted if this is the case.

    In line with government guidance, 2nd doses are only currently being offered to people who are 18 and over.

  • Why are some people being offered a third dose?

    Third doses of COVID-19 vaccines are being offered to people who are severely immunosuppressed. This includes those with leukaemia, advanced HIV and recent organ transplants. These people may not fully respond to vaccination and so may be less protected than the wider population.

    The third doses is part of the primary course of vaccination and is separate to a booster vaccination, which will probably be provided within six months' time, once further advice has been received.

    The timing of the third dose will be determined by clinical teams but is usually provided 8 weeks after the second dose.

    The third dose should be a mRNA vaccine (Pfizer BioNTech, or Moderna) unless there is a specific reason such as a previous allergic reaction.

  • How do I cancel or rearrange my appointment?

    If you booked a vaccine appointment through the national online booking system, please log onto the system and make the changes you need.

    Please use the online booking link you have received to book your or your child's appointment. If you are unable to book this way you can phone the vaccine booking line provided.

    If you received your vaccine at Guy's or St Thomas' Hospital and your records are not showing correctly, please email and we will respond to you within 48 hours.

    We are unable to amend any vaccination records for vaccines that were administered, and records uploaded, elsewhere. Please contact the vaccination hub where you received your vaccination, or contact your GP who will be able to look into your query further.

  • I received a text message asking me to book my vaccination appointment by clicking on a link. Should I open it?

    We are sending out invitations by text message to book your or your child's vaccination appointment online.

    The text contains a unique booking code and you will be asked to provide this and your postcode when booking online. No other personal information is required.

    There have been reports of text message scams where the link goes to a fake NHS form which asks for bank details as proof of identity. The NHS will never ask for banking information.

    Information about scams and what you should do is available on the national cyber security poster (PDF 905Kb).

  • How do I prove that I have been vaccinated?

    You can prove your vaccination status through the NHS app or through the online COVID pass service.

    You can also request a letter through the COVID pass letter service. We are not able to provide you with these letters.

  • Can the AstraZeneca vaccine cause blood clots?

    The Medicines and Healthcare Regulatory Agency (MHRA) has issued advice that there is a possible link between the AstraZeneca vaccine and 'extremely rare and unlikely to occur' blood clots with lowered platelets. National guidance has been updated and anyone aged under 40 in the UK will now be offered an alternative COVID-19 vaccine. The risk of developing a blood clot is estimated to be approximately 4 in 1 million.
