I was told when I had mine yesterday that it was the Astra Zeneca vaccine. I was given a leaflet about what to expect regarding reactions,, and I was told that if they continued for 3 days to get in touch with my Doctor.
Headaches were amongst the symptoms and I was advised to take paracetamol if this happened.
I have been lucky, and not had any reaction whatsoever. I hope that you will be feeling better soon, but if the symptoms persist get in touch with your Doctor.
I am booked in to have my second jab on the 18th April.
