There are 2 things he mention that is not correct

1. Blood clots ...the vaccine is localized in deltoid muscle it does not travel all over your blood vessel as it is not injected into bloodstream.

2. He claim that the virus is harmless as we all already have antibodies...but we know from earlier waves before immunisation the death rate...many died until not enough coffin in Italy and later India.

The virus is not harmless as claimed by this doctor.

I have already said few times. Nobody actually really know how bacteria and virus environment  function.
It cannot be explained clearly and you have to accept the fact the result is like this.

Blood clot. As long it did not move to your artery
You actually do not need to worry so much.

Virus is in fact a non living thing. It is nothing wrong to say it is harmless. How come so many ppl kena infected due to this new virus. It is probably due to the poor response of your immune system. Better boost up your immunity.
Probaby your chest already empty...

Man made thing is always had a certain level of risk. Normally they wont tell you the bad stuff.
If they dont strictly follow Law of nature to produce the vaccine. The impact may be deadly
