Your stories about vaccine shots allegedly destroying your dad's health are anecdotal.
If his illness is not related to Covid infection then there may be thousands of underlying conditions that caused his dad's deterioration of health and are likely to have nothing to do with being vaccinated or not.
We do know his age and medical history.
It seems to be another typical example of anti-vaxxers' confirmation bias and cherry-picking to confirm their anti-vax worldview and bias.
It's actually sad that many anti-vaxxers mindlessly exploit (because they are medically/scientifically illiterate) the suffering and death of their close ones to perpetuate the anti-vax agenda.
You have been calling medical professionals all sorts of derogatory terms for years so I would not be surprised if he did that directly towards them in the hospital too.
