I wrote about the bizarre move to douse #Shanghai in clouds of disinfectant as part of its “grand assault” on #Covid-19.
Why spend so much energy on a virus that rarely spreads via surfaces? The answers are more about politics than public health. -- @AFP

Unfortunately the article only contains speculation, it's not like officials are going to respond to the question "why are you doing this thing we know is ineffective". Anyway, the best guess seems to be that it "conjures up the image of a heroic battle against an invisible enemy"

I guess this makes me slightly less worried that Musk is afraid of angering China, given that they're counting Taiwan as a separate country. Also here's a link to the definition of 'based'

- Omicron shows accelerated evolution
- Latest strain BA.2.12.1 not only has progressively higher transmission, but minimal cross-immunity to BA.1. Many will get reinfected
- BA.1 targeted vaccines will likely be less effective too
- Need nasal vaccine to limit transmission https://t.co/0L1vRS5aBq

When mRNA vaccines first arrived it happened so rapidly that we got excited about the ability to pivot rapidly to new variant-optimized vaccines if necessary.
Now we have new, highly transmissible variants that significantly reduce existing vaccine efficacy and … crickets.
Nasal vaccines reduce spread of the virus, we should be developing these faster!
