Excellent post Missedout.
What I did find out is that for those of us who received the AZ vaccine, it may only offer 40 % protection. The third primary vaccine must not be AZ. Yet initially, I was told the AZ would be more suitable for those who were immunocompromised.
I am exhausted being passed from pillar to post, with no solution.
Thank goodness, I too am able to fight my corners. Other may not be so capable.
Why no book recommendations on Mumsnet.
