Has anyone been sent a text to book a vaccination that they weren’t expecting ? Im mid-40s, no underlying health issues that I know of (I haven’t been to a doctor in 15 years) and I received one Friday. Clicked on the link and was able to book one for this Friday. Of course now Ive gone all neurotic, feeling guilty for taking it and worrying that I have some health problem Im not aware of. Im like Woody Allen barring the kiddie fiddling.
