The story says
Known as Adam (a pseudonym), he is under Court of Protection orders because he cannot make decisions for himself. In 2021, the care board obtained a court order allowing the sedative method, deemed necessary due to Adam’s risk factors, including Down’s syndrome, autism, and obesity.
Maybe they desperately want to force vaccination on him for some underhand reason. Or maybe they care about his well-being and genuinely feel that vaccination is in his interests.
You can certainly believe that the risks are lower in 2024 than in 2021. It's true for most of the rest of us largely because of vaccination and/or infection which may not be true for Adam, so vaccination may well still be highly desirable for him. Presumably the court will again make that determination.
