Dr. Ronan Glynn:

The one caveat to that is the issue of variants. While we have reasonable confidence around the duration of immunity with vaccination in the context of the B117 variant, we are not as confident regarding the South African variant.

In response to the question on people travelling for vaccination, I would hope that, in so far as possible, people are getting vaccinated close to home, but I also recognise that this may not be possible in every scenario for a variety of reasons. I cannot speak to the detail of that, unfortunately.
