l will have the booster when offered as l caught Covid on 15th Sept and was very ill for a month.l never want to go through that again.. l lost 1 and 1/2 stone as l couldnt eat as l lost all appetite. l caught it off my husband who was ill on the 13th but his symptoms were less & lasted only 9 days. He had already had his 2 vaccines but id only had one, so l think that's why l was more ill. He had high temp(100) and loss of smell but l had temp of 103, loss of smell and taste and much more problems, so l think l had the Delta plus virus, even though at time l had already had my 1st vaccine in August when l caught it in Sept.. lv just had my 2nd vaccine and had 24hrs of feeling as if l had the flu, After that 24hrs l was back to my M.E baseline. l have severe M.E, now for over 45 yrs. To be honest, my Covid illness experience is something l dont want to go through ever again if possible, so i'm having the booster if there is a chance it will lessen me catching it again or reduce Covid symptoms. Covid is nasty, its not like the flu, if l hadnt had my 1st vaccine l dread to think how much more ill or worse , l would have been.
