I don't suppose anybody knows if a teenager with one kidney is OK to have the covid vaccine? I can't find a definitive answer online although, to me and what I've read, it appears to be fine...obviously I'm not a medical professional!
Nephew is due the vaccine, his mother hasn't (and won't) try to find out and father hasn't managed to speak to a Dr as works unsociable hours and unable to get through at the times he's been able to call. 119 say to ask your GP.
