Dollymixtures As far as I know, you can't just ring up and book a vaccination whenever you want. You have to wait for a "window" and maybe wait to be invited depending on your age/health. I was invited to have the latest one, but when I checked, it turned out that I didn't meet the criteria to have it, so I will have to wait until autumn/winter. I don't even know what the arrangements are or even whether there will be one.
Maybe use the time to do some proper research by reading peer-reviewed articles and official data. Please ignore the scare-mongering and social media posts which don't give sources and evidence. If something is coming from a known anti-vax site, you can guess that it's going to be biased.
Nobody can tell you what is the right decision for you. Factors would include your age, medical history, reaction to previous jabs and if you've had Covid before, how long you to took to recover. There is overwhelming evidence that you are more likely to have health problems form Covid infection than any vaccination. It's about risk and balance.
