Evaluating COVID-19 Vaccine Boosters (COV-Boost)

COVID-19 vaccine booster comparison study: Volunteers wanted.




We are looking for volunteers to take part in a study looking at the use of different COVID-19 vaccines for giving a third dose. This study is being run by Portsmouth Research Hub, and is sponsored by University Hospital Southampton NHS Foundation Trust.


You may be eligible to take part in the study if you:

  • Are aged 30 years and over
  • Received your first COVID-19 vaccine in December 2020 or January 2021 and have also received your second dose booster

We will provide reimbursement for your time, inconvenience and travel (depending on what group you are enrolled in). The total study participation time is up to one year.

If you are interested in finding out more, please visit our website: www.covboost.org.uk where you can also complete the pre-screening questionnaire to see if you will be eligible.
