I has my 3rd primary vaccine 17 September and Wednesday I was informed by text from my GP surgery I was due my booster and there were drop clinics Thursday and Friday. Went in yesterday , no queue. Retired GP did my booster and was fully aware of requirements for immunosupressed. Strictly speaking booster was due today and computer said no but she was able to override it.
I hope everyone has the positive feedback experience I had but not confident. Information is there for GPs.
