If anyone wants to know what this possible solution is I have written it up here in non-technical language [0]. 0. https://www.tillett.info/2020/04/05/a-solution-to-covid-19/ Edit. HN seems to have put me on the “posting too fast” treadmill so I will have to edit this post. While effectively the same as a vaccine, it is quite different. Any such attenuated strain identified can be used outside of the regulatory syste…
> test asymptomatic people for COVID-19 and then genome sequence the SARS-CoV-2 strain that has infected them with the aim of identifying a virus with mutation(s) in an essential viral gene(s) But without these essential genes the virus would not multiply / infect people anyway, right? Also, how is it different from inactivated vaccines that are currently being developed ? Also, why cant someone engineer such a virus…
2. An inactivated vaccine will have to be given again and again. A live attenuated vaccine can drive the dangerous strains to extinction. Also attenuated vaccines protect those not vaccinated.
3. In theory you could engineer a virus with deletions, but nobody knows what deletions will work. By using natural deletions you know are mild you get around this problem. It also solves the regulatory issue as you are not going to be able to quickly test a lab made strain.
