Why is that more interesting? Reducing severity is just as important as reducing transmission, if not more important. If we could sufficiently reduce (or eliminate) severe cases and deaths, it wouldn't matter how contagious it was. Common colds are highly transmissible, but no one worries about them much since they very rarely cause severe illness.

Only in that the effect on severe illness (reduction) has already been demonstrated through the studies/trials, this is not really news. Transmission effect is still being understood.

Fair enough when you put it that way :)

Until we have challenge trials, how do we know whether or not other variables, such as natural herd immunity and seasonality are not also significant contributing factors to the 'substantial reduction'?

The numbers from Israel seem to show the 60+ age group that has been vaccinated with two doses is seeing a sharp drop in hospital admissions compared to the under 60 group that is still mostly unvaccinated. This should rule out the herd immunity and seasonality arguments. https://i.imgur.com/Tu3ckZN.jpg https://i.imgur.com/1eP5sbi.jpg

I would have expected even lower hospital admission numbers for the 60+ population, I mean taking into consideration that almost 80% of them have already been vaccinated.

Why would seasonality be coming up now when we're a year into this thing?

Do you think we got a break at the beginning that we didn't identify in the numbers?

"By the fourth week after receiving the initial dose, the Pfizer and Oxford-AstraZeneca vaccines were shown to reduce the risk of hospitalisation from Covid-19 by up to 85 per cent and 94 per cent, respectively. Among those aged 80 years and over - one of the highest risk groups - vaccination was associated with an 81 per cent reduction in hospitalisation risk in the fourth week, when the results for both vaccines we…

The AZ vaccine is more effective than the BioNTech one? That's extremely interesting.

AZ had 100% efficacy against severe disease in their 3rd phase interim readout. 0 hospitalization in vaccinated arm, 8 hospitalizations 1 severe and 1 death in the control arm.

In contrast, with pfizer, there were 0 covid deaths in the entire trial (vaccinated or unvaccinated).

Older people with COVID bad enough that they end up in the hospital usually stay there for 3-6 weeks

Give up trying to have any reason or rationality about this.

The world wants this mass hysteria. I'm starting to think it's not even about Corona virus anymore. Everyone has an agenda. From the remote workers to the politicians to the news media to the people getting unemployment.

You just have to let the madness pass as it looks like it's making progress towards being behind us.

I think it has been shown that standard corona seasonality shows the same shape of all case loads we have seen?

That is, most of the recovery we saw last year going into summer could potentially be explained by regular cycles of similar viruses in the areas. The impression being that that could also explain or current recovery.

It is not an argument against vaccination. And I haven't seen people pushing we have heard immunity, yet. But the stark drops we are seeing do seen surprisingly sharp.

I could be wrong, but I think that's after just one dose. The pfizer vax requires 2 doses for it's full effect.
