We have been invited to participate in this survey.
Some of the purposes of the survey are to find out how many people have previously had Covid, with or without symptoms, and how many have had a strong response to vaccination.
We would be having regular PCR tests for virus from the throat and nose. We would only be invited to have fingerprick blood tests if we had a positive PCR test.
But surely to answer the previous questions, we would need to have fingerprick blood tests at the begin of the study, before any confirmed infection?
So I'm curious: has anyone else been invited to participate in this study, and been told they will have a fingerprick test at the start of their participation?
