Booked an appointment with the nurse at my local GP and turned up expecting to have to make multiple trips for these.
Luckily they were able to give me them all at the same time.
I was injected with:
Hepatitis A (Avaxim)
Dip, Tet & Polio Reinforcer (3 injections in one)
And all free. I believe you have to pay if you turn up at your local drop-in center so make sure you book in advance at your GP.
