Wait, that's 1.1m total I assume as has been discussed recently?

Not 1.1m extra vaccines on top of what we already got for q1?

1.1m total

Thought so, usual sh*te from government. He hasn't a clue and the deliveries will absolutely change before end of March.

3.85m expected in Q2 atm so. Plus 1.1m from Q1 leaves us at 4.95m by end of Q2.

Some of these will be J&J and some will be AstraZeneca who will be administering little 2nd doses in Q2 (just the March second doses in June).

Should leave us with >80% of the adult population with one dose by Q2 end.

I would sincerely hope we end up getting more than 3.85m doses in Q2.

Is there anything to point to us getting more Q2 supply though? Everything I've read up to now seems to point to less. I'm just scrapping for some hope, I'm to be married at the end of July so trying to cling onto any good news I can get.

That makes for disappointing reading

Looks likely we will be missing out targets for Q2 as well

Some interesting reading during lunchtime.

https://assets.researchsquare.com/files/rs-310773/v1_stamped.pdf

It describes how the current mRNA vaccines are working within vaccinated humans with a very close look at the lymph nodes and germinal center B cells. GC B cells are important in terms of antibody maturation, longevity of the response and the affinity of antibodies (countering variations in the virus). There is some very interesting data there for those interested. For the TL;DR synopsis, here are a few of the important bits:

In the draining lymph nodes, we detected robust SARS-CoV-2 S-binding GC and PB responses in aspirates from 12 of 12 participants. These responses were detectable after the first immunization and increased after the second.
...
These results with mRNA vaccines are superior to those seen after seasonal influenza virus vaccination in humans, where hemagglutinin-binding GC B cells were detected in only three of eight participants

S-specific PB pool that persists in the draining lymph nodes contained a substantial fraction of IgA+ cells. This observation is intriguing because it occurred after intramuscular rather than mucosal vaccination.

IgA class of antibodies is very important in protecting mucosal membranes as there is very little IgG type antibodies residing in our snot.

Too long for a quote, but previously infected and then vaccinated individuals had a significantly broader response to all circulating variants (good thing).

Note: it's a preprint but their methods look good and the names on the paper look solid (Florian Krammer among them).

Gavin Reilly reported ... Taoiseach says Boris Johnson "doesn't have surplus vaccines to give to Ireland right now".

That does not sound like a no to me. Sounds like no for now but maybe the UK will give supplies to us at a later stage.

He's right there in fairness. They don't have surplus at the minute.

But in the summer when they do have excess vaccinations, and when they are struggling to get vaccinators to work shifts because they have better things to be at like going to the pub or a festival, maybe they can send a few over.

The horse will likely have long bolted at that stage, now is the time for them to help, not in 2-3 months time.

Depends on what happens with AZ, who have said they'll meet their quotas in Q2, despite governments using the decreased estimates in planning.

EU also working with J&J to speed up their manufacturing, and more Pfizer capacity coming online all the time.

Hopefully this time it is a conservative amount that increases rather than decreases, however, if we get to 80% by June, that'll be great for the country.

I think they need to show a more clearer picture.
Last year week 32-46: 6.8% of all cases were in HCW (2.3% of which where hospitalized)
Week 48-8: 10.2% of all cases were in HCW (2.8% of which were hospitalized)

Filtering out week 7-8 this year, it looks to be 9.2% of all cases are in HCW's.
I could be completely wrong and reading reports wrong, all evidence worldwide points to the vaccine having a massive impact. I would just have thought we'd see a bigger drop in HCW's as a % of the general population.

Per the 14 day epidemiological reports in the past 14 days 3.75% of 7,683 cases were healthcare setting acquired. In the 14 days to the 29th of January, this was 13% of 27,348 cases

How ? 3.8m is listed as the Q2 target. No change there

Ah I was going by the HCW reports.
Going by the 14 day epi reports you can see the week on week reductions in HCW's as a % of total new confirmed cases.

It would be political suicide for Johnson to start giving away vaccines right now. They need to vaccinate more of their population before he can do so

Which would be 100% or very close to all adults who want to/can get vaccinated.
15% have said they don't want an approved vaccine.

It was me and we agreed to wait and see who was right at the end of the month. Not complete BS. The IT article was in relation to the Taoiseach's comments.

The article quotes the Tanaiste.

As is well known now looking at Jan and Feb , until its the end of march we really won't know will we ?

I think the difference between it is 150,000 vaccines.

Slightly and welcomingly muddled by the extra 46500 Pfizer announced today,

EU are being too nice imo when we're not getting supplies promised. Particularly shipping to US who refuse to ship to anyone else atm

seamus

It's a good opportunity for the E.U. to tighten up on exports. The evidence is right there that the EU has not engaged in vaccine nationalism despite manufacturers continuously letting us down even while exporting doses out of the EU.

The US or UK would have no basis to complain about the EU engaging in a little bit of vaccine nationalism at this stage.

Warn manufacturers that if there are any further shortfalls in delivery, their products will not leave the EU until the shortfall has been rectified.

Whats the UK done apart from making sure that they have ring fenced their contracts?

Also there is a massive difference between being open about what your going to do RE the USA, and changing the situation this late after condemning similar last year.

UK is an export ban in everything but name really. It might not be as harsh as the US one but they're not exporting vaccines like the EU (we exported 8m to them). My opinion is unless they're going to play fair we shouldn't with them or the US.

In order to speed up the translation from those with the expertise, and in the best traditions of the Internet, I will post something completely incorrect.
It means that the Covid vaccines don't work as well on people in Africa.

We're not dicks. Everyone needs a vaccine. We still have given over double our fair share compared to the average

My best understanding, serology tests used to determine if you were previously infected with sars-cov-2 are not as precise in African populations as they are in other groups.

In some tests they did, these tests produced false positives, which means these people were not previously infected, but the tests suggested they were.

What does this have to do with Novavax? When Novavax released preliminary results earlier this year they suggested that 1/3 of people in their trial were seropositive (i.e. had already been infected with sars-cov-2), and they noticed that despite this people were becoming infected again. They assumed this meant people were being reinfected because of the new variant, now those results are being questioned because some of those people may have been falsely flagged as seropositive and in fact the reinfections in some might have really been first infections.

I think.

One of the findings of the South African Novavax trial was a similar attack rate between participants who previously had Covid and those who didn't. Novavax used their own in-house ELISA test to check for antibodies in the participants. This study suggests that ELISAs used in samples from Africa show markedly reduced specificity, possibly due to interference from local endemic pathogens. There's a possibility that the 30% seropositivity rate from the trial may have been an overestimate.

Give me a bit room here, it wasn't intelligence that got me this far.

Antibody tests don't work well on Africans?

They work well on Europeans and Americans, yeah ok, hmmm

Because of that the Novavax vaccine is now a very good vaccine and works well against SA variant

No I don't think it really changes the efficacy results of the vaccine trial, it just effects the observation they made where they seemed to notice that people were getting infected with the new variant regardless of their previous infection status, now it seems like that observation might have been muddied by those tests not being very accurate in some groups of people. In fact what it might be saying is that natural immunity is better than the trial suggested.
