Omicron news

Cheers, any thoughts on this? I'll be coming up to 4 months since my 2nd dose in a week or so.

Prof Paul Morgan, an immunologist at Cardiff University, said there was room for manoeuvre on the six-month gap, already cut to five months for some people.

“If boosters are given too soon, then they’re not as effective,” he said. “But I think six months was more about pragmatism and availability than about immunity. From three to four months on, the immune response should be virtually as good as at six months.”

(from Covid boosters may be expanded as soon as Monday to tackle Omincron spread )
 
IIRC it's the drop in immunity in the AstraZenica version that has them worried.
There's isn't such a big drop with the Pfizer.

Is this based on an observed drop in antibody levels or something else?

Should have named it Unicron. Missed opportunity

So what happened to all the other variants of concern between Delta and omnicron? I remember reading about Lamder, months ago.

The most recent variant given a Greek letter was Mu, back in August - that variant, found in Colombia, was largely eclipsed by Delta, as were Lambda, Iota etc.
 
Yeah we hear about those other variants because they have grown in some locations and/or have interesting mutations, but unless they show signs of outcompeting other strains they tend to fall off the radar.
 

So they are going to ignore this almost totally, instead of being more careful now, such as having more distancing, until the scientists can work out Omicron's potency. Then if it is potent then we'll end up with another lockdown and being in a lot worse situation.

It's just depressing.
If only omicron had waited until after Christmas, then they might have actually done something about it. But 'cancelling Christmas' would actually cost the Tories more votes than 1000s extra deaths, because people are trash, and the Tories know that.
 
Shit, two cases now reported in Canada -both with recent travel to Nigeria but apparently not southern Africa.

According to Our World in Data, 1.7% of Nigeria's 211 million people are fully vaccinated.

Obviously you have to balance the intra-dose interval timing with your own personal risk of infection and circumstances (medical history including previous exposure to antigen, factor in vaccine types, clinical vulnerability, scope/practicalities for enacting NPIs). You could perhaps shorten it to as little as four months but then you could be trading degrees of potency/avidity/durability/breadth, in particular to antigenically diverse VOCs as yet unseen, for shorter term 'immediate'* protection. Indeed, some studies (DOI: 10.1101/2021.11.19.21266555, DOI: 10.1016/S0140-6736(21)01699-8) have found a significantly better overall immune response with intervals of around 8, up to 12 months (though perhaps an even longer interval might eventually be found to be immunologically optimal) and doubtless a fair few instances of hybrid immunity have 'fortuitously' benefited from this effect to degrees too (original first wave convalescents not receiving an initial vaccine dose for up to a year or more).

*e2a: 'immediate' here as in 'within a couple of weeks'.

Six cases just announced in Scotland bringing total in UK to nine so far.

As I read this unfolding, I am reminded of the Hindu scripture, the Bhagavad-Gita:

"I am Omicron, destroyer of worlds..."
 
Six cases just announced in Scotland bringing total in UK to nine so far.
Some important detail on that one. Stuff that sometimes surprised people during the early days of past variants but is to be expected and will probably surprise people less this time:

The Scottish government announced on Monday morning that six cases of the variant had been identified in Scotland, with four in Lanarkshire and two in the Greater Glasgow and Clyde area.

Some of the cases identified in Scotland have had no travel history and caught the virus variant in the community, Deputy First Minister John Swinney told BBC's Good Morning Scotland.

Thaks very much for your thoughts on this. As with the initial roll-out, I will have quite a lot of wiggle room and personal decisions to make, because my circumstances mean that my risk of infection is almost zero, with leaving the house to get vaccinated being one of the exceptions to my near-zero risk.
 
The great news about it already being everywhere is that we will find out how it behaves in terms of vaccines and hospitalisations much sooner than we otherwise would.

I admire your optimism! Same as the good thing about cancer is that it's so common we have loads of experience dealing with it and impetus to develop treatments and cures. :thumbs:

I was somewhat impressed that they acknowledged this sort of thing in todays press conference, and justified bringing the gap down to a minimum of three months on the basis of balancing the benefits of a longer gap with trying to get the timing right in relation to a new wave arriving. They mentioned a study that used a three months gap to justify using that as the lower limit.

More virulent, less lethal? That's what happens in vírus evolution, right? Hopefully it's the good news the world has been waiting for. We should know in a couple of weeks. Fingers crossed!

We don't know yet.

“We’re seeing a marked change in the demographic profile of patients with COVID-19,” Rudo Mathivha, head of the intensive care unit at Soweto’s Baragwanath Hospital, told an online press briefing.

“Young people, in their 20s to just over their late 30s, are coming in with moderate to severe disease, some needing intensive care. About 65% are not vaccinated and most of the rest are only half-vaccinated,” said Mathivha. “I’m worried that as the numbers go up, the public health care facilities will become overwhelmed.”
