I’m obese sadly. BMI over 50 and fat arms. Working on it but it’s slow progress. I have had my 2 doses of Pfizer but I have recently read that the NHS guidance is to use longer needles for obese people otherwise enough vaccine doesn’t go into the muscle. The vaccinator didn’t seem to make any sort of special trip to get a longer needle so now I’m worried. Do the vaccinators know that this is the guidance? Should I ring up the hub and find out? It was done at a doctors which was a hub so if I ring them up would they know?
