I asked the same questions about a year ago.
Thought the knowledge base would have been updated.
Yes, I used the term “vaccine” instead of “shot”.
Got the same answers.

I was informed that: (in my words)
-no one has died from the shot
-minor short lived side effects
-they are safe and effective

There must be a filter applied to controversial topics that they can not reveal.
Many other unrelated questions were asked in which AI replied incorrectly. Can only respond within their parameters.

Medical AI is being used to assist in diagnosis. Neighbour just dropped by to tell me about his Doc using it to verify her diagnosis over on a telecall. It’s like everything else. It depends upon the knowledge base used or it becomes Garbage in, garbage out.

Can not trust AI to give an honest answer everytime.
