Re: Vaccine rollout in the UK

Doesn't mean that you shouldn't vaccinate people as soon as possible, given that you don't have a time machine.
This is probably too pessimistic. They are also very good at stopping asymptomatic infections, and even those who develop infections have lower viral loads, which likely reduces transmission. See Table 1b and the text under it, with references, here, which says:Herainestold wrote: Sun May 16, 2021 6:16 pm The other thing to note is the lack of sterilizing immunity with these current vaccines. They are very good at stopping severe disease and death but they do not stop transmission. Vaccinated people can be infected and pass it on to the unvaccinated and immuno compromised.
If it's young people and it's increasing for several weeks why not? Younger people develop far more relative immunity far quicker than older people. Several days, if I remember the graph I saw (I can't recall where).Herainestold wrote: Sun May 16, 2021 6:16 pmYou cannot vaccinate your way out of a covid surge. As noted above, the time lag to generating effective immunity is anywhere from two to eight weeks after vaccination.

I can see data for the North West which breaks it down into 0-5, 6-17, 18-64... but that's not very useful.bob sterman wrote: Sun May 16, 2021 12:51 pm So on TV today Hancock emphasised the importance of vaccination by saying...
Now perhaps I'm just too cynical - but his choice of the present tense ("are eligible") caused me to raise an eyebrow.
Working backwards - with typical lags between infection, symptoms and hospitalisation - to prevent a hospitalisation in early/mid May - someone would need to have been vaccinated in mid-April.
And as there is typically a delay between becoming eligible to book a vaccine, and the first available appointment, to prevent this hospitalisation in early/mid May the patient would probably have needed to become "eligible for the jab" in early April.
(Obviously - this isn't a comment on the effectiveness of the vaccines against the new variant - rather a comment on Hancock's implication that most hospitalised people might be somehow responsible for their unvaccinated status).

A certain number of breakthrough infections will occur and vaccinated people will sicken and die.
The proper response to this dangerous strain is renewed restrictions. Lockdown, enhanced masking including outdoor mask mandates and double masking, which the Indians feel will protect against this variant.
Is there any more UK data regarding asymptomatic infection which would also cover AstraZeneca?bolo wrote: Sun May 16, 2021 6:49 pmThis is probably too pessimistic.

In the US general adult population, 0 days after the second dose of Pfizer or Moderna, there is an 80% risk reduction for asymptomatic infection. In the general population in Israel, 14 days after the second dose of Pfizer, there is a 94% risk reduction for asymptomatic infection. In Israel (preliminary), those who become infected after vaccination with Pfizer have 4x less viral load.

Fixed that for him.Harrison said it would be foolish to [allow further unlocking] without first boosting vaccination rates in areas of high transmission

No. Priority 1 should be vaccination. Nobody should stay at home rather than go for their vaccination.Herainestold wrote: Sun May 16, 2021 8:48 pmGiven limited resources, priority 1 should be lockdown, priority 2 vaccination.shpalman wrote: Sun May 16, 2021 6:27 pm Doesn't mean that you shouldn't vaccinate people as soon as possible, given that you don't have a time machine.

You can lock down everybody at once, but you can't vaccinate everybody at the same time. So lock down now. When you get your invitation , double mask, go directly to the vaccination centre, get jabbed, go home and isolate for two weeks to let the antibodies build. Don't even think about going outside.jdc wrote: Mon May 17, 2021 1:23 am I'm struggling to see why we need to prioritise lockdown or vaccination. What's the reason we can't do them simultaneously? You say 'limited resources' but I can't think of any that are common to lockdown and vaccination.
Mind you, it is late. My imagination might have gone to sleep already.
The point is that the moral argument for lockdown is shaky and knee-jerk memories of a year ago when lockdown was essential are destructive.Gfamily wrote: Sun May 16, 2021 11:06 pmIt never was, did you have a point? Or, maybe, you might prefer to clarify the point you are making.
Swift action saves lives. If lockdown is delayed, it is harder to implement and less effective. Lockdown now to stop the Indian variant. Concentrate vaccination on the hot spots. Keep people inside for two weeks after vaccination. Do this now and the problem is gone by next month.wilsontown wrote: Mon May 17, 2021 11:59 am Indeed, we know that lockdowns are a social and economic disaster so we shouldn't be doing them unless we absolutely have to. We did have to lockdown to get case numbers down from the catastrophic levels they ended up at in January, but allowing people the (still fairly limited) freedoms they currently have has not led to a surge in cases, so why lock people down more severely?
I can see the argument for possibly rolling things back if today's opening leads to a resurgence in cases, but we'll see what happens on that...
The problem is, it hasn't been studied as much as indoor transmission. It is hard to capture and isolate the virus in the open air. Look at how China beat the virus without vaccines. Some people were inside their flats for six months! Brutal but it worked. We just need to do this for a short period of time while hot spots are vaccinated.headshot wrote: Mon May 17, 2021 6:12 am I’ve had enough of this b.llsh.t. You need to show evidence that transmission outside is significant. Telling people not to leave their homes, at all, is ridiculously over-cautious and damaging.
There's not enough doses to do that though. Voluntary uptake will probably be enough - eventually. Till then, options are lockdown, or accept some cases and hope they don't get out of control again.lpm wrote: Mon May 17, 2021 2:12 pm There's some people who love government force, aren't there.

Vuluntary uptake, we might have to "encourage" people to get vaccinated, like they are trying in America.Bird on a Fire wrote: Mon May 17, 2021 2:34 pmThere's not enough doses to do that though.

Judging by the photos of queues, the limit is still how quickly you can get the doses to the people.*Bird on a Fire wrote: Mon May 17, 2021 2:34 pmThere's not enough doses to do that though.

A couple of weeks ago the 45-50 age group was basically finished, with a start made on 40-45 in many locations. Over 50s were 100% offered over a month ago.shpalman wrote: Mon May 17, 2021 2:49 pm I'm sure by digging through this thread someone else can figure out roughly what age range was being vaccinated 2-3 weeks ago in that region.
