Not great reading that the first 2 cases were both admitted to hospital
Both had very mild symptoms despite being admitted to hospital
David Hui, a respiratory medicine expert and government adviser on the pandemic in Hong Kong, said that even though it is not clear if current coronavirus vaccines are effective against the new variant, the city's vaccination rate should be increased and booster doses should be implemented as soon as possible.
He said that the two people who tested positive for the omicron variant had received the BioNTech-Pfizer shot and exhibited very mild symptoms, such as a sore throat.
I think all 13 Dutch cases and both Australian cases were asymptomatic or had mild symptoms, same for many of the SA cases. Anyway, saying at this stage that it
definitely causes milder disease is as inaccurate as British scientists saying it's horrendous and the worst ever .
Interesting bit on twitter
If we're unlucky, omicron's ability to (re-)infect immunised hosts doesn't significantly impact its high replication rate (and the damage it causes to host tissues).
If we're a bit lucky, its ability to (re-)infect immunised hosts does reduce its replication rate, and hence would be expected to cause on average less severe symptoms, send fewer people into hospital and reduce fatality rates if it spread
If we're really lucky, omicron not only replicates less well in host cells, but also causes less systemic infections by replicating preferentially in cells of the mucosa of the upper airways, which are poorly protected by vaccine induced immunity
