There are several versions of COVID-19
The 'mutations' existed along side the original from the lab origins.
Q's post suggested the existence of at least two. (search COVID-19[2], why 2, what is 1?)
So they release the mild but highly contagious version, then they can send an agent to infect targets with the supped-up killer version.
target Trump
target newly elected Republicans
etc
Given the existence of these weapons, Q et al assumed it was best to allow the mild contagious one to spread knowing that it will help ward off the effectiveness of strains that are known to be better at killing.
There are versions to target Africans, Chinese, Europeans, and other races.
The research started in Israel, but was moved to North Korea and Wuhan in part.
The strains were tested on humans in North Korea, not only natives but trafficked and farmed humans.
Wuhan China will take the blame to protect the world from wanting to destroy the Jews.
The plan in part protects the lives of all non-cabal people, which includes 99.9% of Jews.
