You are misinformed. Mutations are always weaker. Never in the history of viralogy has a virus mutated into a more dangerous strain. Mutations are defects. It's alarming to me that acknowledging this fact is itself being regarded as "misinformation".

Vaccine advocates are ignorant of the dark and painful history of vaccines. Many have become convinced that only vaccines can end a pandemic. This has never been true, never will be true. It's an urban legend. Our civilization is self-destructing.
