Dr. Ronan Glynn:

In response to the first question, the duration of immunity is an open question at the moment. Our current position is that people can reasonably expect to be protected for a period of up to six months after being fully vaccinated. In fact, I would be hopeful that the duration of protection will extend far beyond that but we simply have not had enough time to collect that data because people have not been vaccinated for long enough yet. The evidence is promising and this is something we are monitoring on a monthly to six-weekly basis. I anticipate that we will be saying further positive things about the duration of immunity in the coming weeks.
