Professor Brian MacCraith:

I will start with the second part of the Senator's question about the certificate. Within the work programme we are on the IT infrastructure and so on. Discussions are under way about the nature of any potential certificate but it is a certificate of vaccination and nothing else. That is a record of the fact that one has taken the vaccine, the number of doses and the type of vaccine. There has been a conflation publicly between a vaccination record or certificate and now the immunity passport, which is something quite different, particularly as we do not have anywhere near enough information about the impact of the vaccines on preventing or reducing transmission. That will come in time. Throughout this programme, both at national and European level, there was a long discussion on having a simple record of vaccination, whether that be a hard copy or a digital or both, but those discussions have not concluded yet.
