I am posting this as it could be useful to others.
I got my 4th covid jab on Saturday even though I am not of the age of 75 and over (well I am getting there

) .
So how did I manage to book it and get it.
I use 'SystmOnline'
https://systmonline.tpp-uk.comfor my doctor surgery, booking appointments or repeat prescriptions etc.
Under '
Booking Appointments' I spotted 'Covid Booster' so clicking on it I could make a booking.

Well I though I would get my wife to drive to the doctors to see if I would get it or not, surprise the receptionist just said sit down and wait for you name to be called, about 6 in front of me and about 12 came in after me (Not all looked 75 or over)
My turn next, the nurse asked if it was my 4th, yes, told me it was for 75 and over, I said I had booked on 'SystmOnline', ok she said, I said maybe it's because I have a weak chest, yes she said and then told the 'Admin lady who was inputting the data on my medical records to add me on.
Then I had my jab

'Pfizer'
One theory the nurse though they need all the jabs to be used up once they are out of the freezer, so open it up to others to get it to .
