Coronavirus (COVID-19) vaccination clinical trial participants

NHS Scotland are extremely grateful to everyone who has volunteered, past and present, for coronavirus (COVID-19) vaccine trials in Scotland.

How to access your record of vaccination status if you've received a primary course

Participants on the following primary course vaccine clinical trials should now be able to access their record of vaccination through the COVID Status app or by downloading a paper copy online:

  • Oxford/AstraZenca
  • Janssen
  • Novavax
  • Valneva
  • Medicago

For Janssen, a single-dose vaccine is authorised for use in the UK. Participants that have had 1 or 2 doses as part of a clinical trial are considered fully vaccinated.

Further information on how to get your vaccination status

If you have a problem accessing your status, you should phone the COVID Status Helpline on 0345 034 2456.

If you are or were on a booster clinical trial

There are other trials active in Scotland. These are mainly studies of additional doses or booster vaccinations.

Participants who have been unblinded and issued with any of the following booster vaccinations as part of a clinical trial should now also be able to view their vaccination status on the COVID Status app or by downloading a paper copy online:

  • Moderna
  • Pfizer
  • Valneva

Participants who have received a booster vaccination as part of a clinical trial and remain blinded cannot, at present, access their vaccination status.

These participants should have received a letter from their Principal Investigator which acts as a record of vaccination status. Participants who have not received this letter, or have lost it, should contact their Principal Investigator to arrange for a replacement.

Coronavirus booster vaccination

The Joint Committee on Vaccination and Immunisation (JCVI) has agreed clinical trial participants who are eligible for boosters should be offered them in line with the main eligibility criteria.

If you’re invited for a booster vaccination appointment, you should attend to have your booster dose.

If you think that you are eligible for a booster dose and have not been invited, you should phone the national vaccination helpline on 0800 030 8013.

If you're still on a clinical trial, your Principal Investigator and study team will advise you about receiving a booster dose and they'll make arrangements with your local health board for a vaccination appointment. You should discuss this with your Principal Investigator and study team, even if you have received a vaccination invitation, or if you feel that you are eligible for a booster and have not been invited.

International travel

If you're planning to travel abroad, you should always check country entry requirements before traveling.

Clinical trial participants, including those participating in coronavirus booster trials, can discuss the possibility of getting additional doses of an authorised vaccine, to facilitate travel, if required. Principal Investigators will discuss this on an individual basis and, if agreed, arrange for the authorised vaccine to be administered by your local health board.

Who to contact

The information that you received about your clinical trial will contain contact details for your Principal Investigator. If you don’t have this information, you can email the NHS Research Scotland team at
