Had my first Pfizer jab. No issues what so ever apart from a sore arm the next day. Feedback is the AZ/Oxford is causing more mild side effects such as cold like symptoms.
Regards supply - the actual issue for pfizer is the supply of syringes. Apparently it is slightly adapted and they have not realised they can get more doses out of a vial which has led to a shortage of syringes (EU sourced).
And apparently more a case of over shipment to Yorkshire so they are re-aligning supply accordingly.
