Yes, hate to say this but I read today a Norwegian vaccination expert saying she was afraid the immune response causing the severe blood problems in a few recipients of the AZ vaccine could be in the what she called adenovirus (or cold virus) delivery method common to the AZ, Johnson and Johnson, and Sputnik vaccines. It was one of 4 possibilities she thought. Think I read Chinese vaccines use the same methodology too.
And in most of the yearly flu vaccine too I believe !!!!
Oh dear
