Don't see the point in the cross over trial, they will only inject me with saline.
The dr did talk to me about if I thought any other teachers would be willing to come forward who have had the national roll out vaccines for a separate arm of the trial where they could test for antibodies.
I did say that the main barrier to that would be time, teachers can't just book a morning off to give blood, they would have to offer a Saturday clinic or late afternoon/evening for people to take part.
He said they had discussed that at a previous meeting.
