My GP has sent a message and a reminder telling me to book my booster but I am mid 30s with no health conditions, not a carer or NHS staff (I am a teacher) and only had my second dose of Pfizer towards the end of May. As far as I can see I am not eligible so am unsure why I am being offered this. The NHS system will let me book it though for next week so I’m not sure what is going on. Has this happened to anyone else?
