If you say this often enough you can convince yourself it would never happen to you, only the undeserving sick and weak.The press release says none. Perhaps the anti vaxxers will suggest they have underlying conditions they didn't know about - so could anyone.
I don’t need to say it often enough since I have decent protection from Covid anyway and am very healthy. But an article from ITV won’t give you much a picture about the reasons and - yes - they or some had underlying conditions they didn’t know about.
It’s OK to question the media, especially now with their ongoing Project Fear campaign.
