This is warning to anyone who has had the vaccine. I had my 1st injection on 16th December and from a few days after until yesterday I have been running high blood glucose. My Humalog just didn't seem to be working. I ended up having to have around 50% more per injection at get it to take effect. I have seen several other people comment on this on the Libre Users Facebook group. I have reported this to the MHRA via the Yellow card warning scheme - Yellow Card Scheme - MHRA
