I think the clearest article on topic is from Zeynep Tufekci https://www.nytimes.com/2021/06/25/opinion/coronavirus-lab.h... who says , repeatedly what we do not know and what is disturbing.
Zeynep has been wrong so many times during the pandemic that it hurts. She will not admit to it, though. She claimed that the Delta variant would end the pandemic, in the same way it is claimed for Omicron now. She's very naive about how the immune system works. Her writing is generally more propaganda than science.
Whilst I agree that she (and most other science reporters!) use simplistic models for immune system responses (possibly more for her readers), I’m yet to come across anything she’s written that has been very clearly wrong or she hasn’t later corrected/clarified.
