Vaccine roll out.

After reading the posts on here, I think there was a possibility that I experienced a reaction, the week following me getting the pfizer jab my joints were very sore, and I had to use a stick when out walking, but then I had been doing a bit of sawing of wood and shoveling and carrying bags of gravel as well as shifting furniture, now still doing some of the same but no problems, if I had been told there was a possibility of such problems before getting the jab, I would still have had it, don't understand why some folk don't want it
