Glad to hear you're back on your feet GB 

Not glad to hear about the arthritis issue since I have psoriatic arthritis. You can PM me if you don't want to get into specifics here but what do you take for it? I'm on Enbrel (an injectable) once a week. Wonder how that will interact with this?

Thanks,

I use Ginger, Turmeric with Curcumin, B-12, Fish oil, Mens multi vit, milk thistle extract, Vit C immune support.

I also use topical Voltaren that I get in Mexico. It's double the strength of what you can get in the US and cheaper.

My wife is getting her 1st shot today. I asked her to make sure they tell her what brand she is getting and to do all she can to nail down a follow up appointment. 

I have seen horror stories on the news about the vast number of people who are overdue for their second dose and I don't want that to happen to her. 

I also worry (and maybe this is unfounded) about people getting Pfizer for their first shot and then, because of availability, getting a different brand the 2nd time. I assume there is some quality control going on there. 

I always thought I would be the first in the family to get the vaccine, but being in education, she beat me to the punch. I am still on a wait list. 

Here in Az they scheduled both shots three weeks apart at the same time. When I got there for my second shot we all confirmed Pfizer and away I went. I have no complaints about the system I used and how they had it set up.

A few months back (Aug-Sept 2020), the issue of amplification cycles affecting PCR tests was also being discussed soberly in center-left media. Examples from The New York Times, MIT Medical School, and The Advisory Board (who's 'The Advisory Board?'). Maybe back in the spring, amplification cycles were a big thing for COVID deniers, but that's not universally true anymore.

In researching amplification cycles, I did find various links to Twitter pages and such ... most of which were, yeah, about what you expect from social media. So I just rejected all that out of hand and looked for more grounded information from better-rooted sources.

Thank you for the links. The New York Times story I remember quite well, which specifically mentions 40 cycles. I knew I'd seen that before.

I still think that retail pharmacy will play an important role in getting the vaccine out but I think it may take some thinking outside the box. Today we did an ‘in store clinic’ with both pharmacists working. I was able to increase to 60 doses today from the 20 I normally do and I could have probably done double that. I focused completely on giving the shots with one tech focusing on paperwork leaving two people to do normal pharmacy business.

Likewise the next two days a group of 10 immunizers will give out 1000 shot each each day for teachers.

I say use the pharmacies as hubs but bring in immunizers to focus on giving shots. With pharmacy techs able to immunize in many states, if opens up a lot of opportunity to do it better than usual.

This is obvious.  We need an army of volunteers to handle admin tasks while trained folks do the jabbing.

Why can't the US mobilize a workforce like we do for the census? 

Companies should give their workers days off to volunteer in this effort.  It will shorten the time to "normal", build community, and result in fewer deaths.

From what I've been able to gather, the two aspects in red are related when filtered through a popular understanding of the science by non-scientists.

"False positive", used colloquially, can mean "having no virus or viral fragments whatsoever" ... but it can also mean "having a small number of noninfectious viral fragments still detectable". For the purposes of the layman ... "being virus-free" is equivalent to "no longer having enough virus to infect others".

My question on this is... if you already have their vaccine in you, I assume this means you'd need a third (or more) "update" or booster shot?  Or, looking ahead, basically we might be looking at yearly flu-shot-like type deal here, it seems?  If so, it seems the single-dose vaccines due to hit the market will be a better long-term solution.

One of them is a "current" false positive. Doesnt really bother me if that makes case count stats. They had it at one point. I want to know the false positive % where they never had it and it is a true false positive. Cant seem to find that.

In the future -- when a sufficient level of herd immunity is reached and maybe a few years past that -- I would expect that even the two-dose vaccines will start being given as single doses. With a possible exception of initial vaccinations for people entering healthcare work, the military, and so on.

Keep in mind that the current flu vaccines don't typically approach 90% effectiveness. My understanding is that flu vaccines' effectiveness regarding infection-prevention are typically ~50% (plus or minus some range, varies year-to-year) but that their effectiveness in preventing severe illness if infected is quite high.

A COVID-19 vaccine, in the future, would be similar. A one-dose effectiveness of 50-80% percent would be just fine for a COVID-19 vaccine in, say, 2029-30 -- presumably in an environment where COVID-19 is largely beaten back (if still endemic).

Right, I get that. The 95% rate of COVID vacc was a homerun, and I think made them initially confident it would cover variants well, but I guess as more data becomes available, now they aren't so sure. And my fear is that it will cause many to say "See the shot doesn't even work!!"

Even the point in red could be nitpicked, but admittedly it would only be an academic exercise.

Let's say someone was exposed to an infectious load of SARS-CoV-2, but their immune system got the drop on the virions and pretty much beat the infection within hours or days (uncommon, but well possible). That person would have detectable viral fragments in their blood stream for some length of time. Would we call that person a COVID-19 case? Or would it matter if we did?

I do agree with you that including "barely infected" people in the case counts is not problematic one way or the other -- it's not enough people to really change the overall story of COVID-19 in the US.

I believe this will be a future booster shot situation, and COVID is endemic. I'm also skeptical that the JNJ will end up being 1-shot solution with similar efficacy as the mRNA vaccines, we'll see. I'm guessing that JNJ data will show that 2 shots will be the only way to get in the 90%+ range. Astra Zeneca looks to be moving to a 2 shot solution with the Oxford vaccine because the 1 shot can't compare to the mRNA results. Just a guess, and we'll find out soon.

I've seen the same data spun different ways in articles; from the "Vaccines aren't working" headlines to "Good news, vaccines work on variants". I do think the efficacy cushion that Fauci was talking about yesterday is a decent way to look at it. 90%+ efficacy to start is really exceptional. Almost unheard of really. There is a lot of cushion there for the current vaccines to be a viable offensive weapon at ending the pandemic, and if efficacy really wanes, the technology allows rapid reformulation. The main thing now is to get what we have in as many arms as fast as we can.

Here's an up-to-date CDC list of the 10 flu vaccines administered in the United States for the 2020-21 flu season. Four manufacturers collectively make these 10 vaccines -- GlaxoSmithKline (UK), Sanofi Pasteur (France), Seqirus (Australia), and AstraZeneca (UK). All have major holdings in the United States, including manufacturing facilities.

Page 3 of this Power Point shows the three dozen worldwide manufacturers of influenza vaccines as of 2012 (before AstraZeneca started producing them). Probably a few players from eight years ago have dropped out, while a few new ones have joined.

We've had internal discussions about this here in Louisiana.  Our guidance has been that there isn't enough vaccine coming to begin mass vaccination sites yet.  

Our Governor today confirmed this. We are basically at a plateau in how many doses we will be receiving of the Pfizer and Moderna vaccines from the feds for the next 4-5 weeks.  Plans are to use the Johnson & Johnson vaccine for megasites when (if) it is approved for EUA.  It needs no special storage requirements and is a single dose, so it would be ideal for the megasites.  

Locally, we think we have the volunteers needed, but not the vaccines.

I doubt mutations which result in competent but immunologically distinct SARS-CoV-2 variants will be frequent enough to warrant yearly re-vaccination. The only virus that applies to is influenza, which changes both by point mutations (single nucleic acid errors during the replication process, which normally occur in non-coding regions of the viral genome) and wholesale exchange of large coding segments for structural proteins between species (typically birds, and to a lesser extent pigs and other critters). The latter mechanism is known as genetic shift, and isn't very common outside of influenza viruses.

This year is different in that SARS-CoV-2 is new, so huge numbers of people have been infected with commensurate large viral populations. The more any virus replicates, the more likely mutations occur. Eventually one or multiple mutations may lead to structural and functional consequences, as we're seeing with the UK and SA strains. It's unclear if we'll need a booster shot to cover those (especially SA) yet.

So if we beat SARS-CoV-2 down to non-pandemic levels, through some combination of natural and vaccine-induced immunity, there will be less opportunity for it to mutate. In concert with its overall slower mutation rate (than influenza) and lack of genetic shift, we shouldn't require short interval revaccination once the pandemic has passed IMO.

DISCLAIMERS:

1. Coronaviruses aren't known to act like flu and swap gene segments between species, but if somehow SARS learns this trick, all bets are off.

2. Immunity to non-SARS coronaviruses isn't believed to be long lasting, but that isn't thought to be the result of mutations. There are other ways coronaviruses (and respiratory viruses in general) evade the immune system, which were described in an article I linked hundreds of pages ago. But revaccination won't likely impact these mechanisms anyway.

 My 86 year old father was able to get vaccinated today. I've been trying to get him an appt. for the last two weeks. Signed him up at University Hospitals, The Cleveland Clinic, the local health dept. and all the local pharmacies that are distributing. Every site says "NO APPOINTMENTS" available when you try to sign up. He called me this afternoon and said "Hey I got a text from the pharmacy by your house. Can you go to this website?" He then proceeded to give me the wrong address multiple times.. "H-T-T-P, CORONA dash blah blah blah..." I'm like can you spell it? "Sure. CORONA.. C-O-V-I-D".  I said, Dad.. You are saying corona and spelling covid... "YOU WANT ME TO JUST BRING YOU MY PHONE???"... Yes dad.. That's a great idea. He came over at 5:15pm and I clicked the link for him in his text. Confirmed it was him and they had an appointment at 6:15 today!

I'm so happy. Happy for him and happy that I no longer have to look for him. For whatever reason, he thought I was in charge of vaccine distribution and called me every day asking when he was going to get his shot.

Bottom line: The virus is getting smarter. Slowly but surely. This underscores the need to vaccinate as many people as quickly as we can, because these mutations are signals of antigenic drift.

What I hope is being done is the Biden administration is drawing up a nationwide prioritization plan, either by age, health conditions, exposure risk or a combination with the inputs of states. Have each state come up with a plan to get them on track with that plan and get them the doses to get them there. Then move through phases as a country rather than a 50 state plan.

For example - tell them that they want to get everyone 65 and older, health care workers, school staff and first responders. How many doses do you need and how long will it take? We need a reset and a real plan at least until the point where it can be opened to the general public.

To determine the factor triggering the sudden surge of daily new COVID-19 cases arising in most European countries during the autumn of 2020. The dates of the surge were determined using a fitting of the two last months of reported daily new cases in 18 European countries with latitude ranging from 39° to 62°. The study proves no correlation between the country surge date and the 2 weeks preceding temperature or humidity but shows an impressive linear correlation with latitude. The country surge date corresponds to the time when its sun UV daily dose drops below ≈ 34% of that of 0° latitude. Introducing reported seasonal blood 25-hydroxyvitamin D (25(OH)D) concentration variation into the reported link between acute respiratory tract infection risk and 25(OH)D concentration quantitatively explains the surge dynamics. Several studies have already substantiated a 25(OH)D concentration impact on COVID-19 severity. However, by comparing different patient populations, discriminating whether a low 25(OH)D concentration is a real factor underlying COVID-19 severity or only a marker of another weakness that is the primary severity factor can be challenging. The date of the surge is an intrapopulation observation and has the benefit of being triggered only by a parameter globally affecting the population, i.e. decreases in the sun UV daily dose. The results indicate that a low 25(OH)D concentration is a contributing factor to COVID-19 severity, which, combined with previous studies, provides a convincing set of evidence.

It was ambitious in December, but there are some headwinds.  Some of which are coming from the fact that the supplies the US create are bound for other countries creating a potential diplomatic problem.  The J/J coming on board has the potential to put 400k/day which is really 800k/day since it's a one shot deal.

It makes sense to roll J/J to the lower risk people, tbh.  I know there are very good arguments against this approach, but it seems like the lower risk people are spreading this and the higher risk people are dying of it.  The vax rollout should deal with that head on by pooling people into two tiers (the ####### tier and the dead man walking tier)

“When these same samples were assessed against the 501Y.V2 virus, nearly half (21 of 44, 48%) had no detectable neutralization activity, with only three samples (7%) retaining titres of ID50 >400 (Fig.2a-right). Notably, all three of these samples were obtained from individuals reporting severe disease who had some of the highest neutralization titres against the original virus.

To define the location of dominant escape mutations, neutralization was also assessed against the RBD chimeric viral construct containing only three 501Y.V2 mutations (K417N, E484K, N501Y) (Fig.2a-middle).

A substantial loss of neutralization was also observed against the RBD-only mutant, with 27% of the samples losing all activity against the RBD triple mutants, while only 23% retained higher titres of ID50 >400.

These data provide more evidence for the dominance of Class 1 and Class 2 neutralizing antibodies in polyclonal sera. However, the differences in neutralization between the RBD-only chimera and 501Y.V2 also highlight the contribution of 501Y.V2 NTD mutations (L18F, D80A, D215G, and Δ242-244) to neutralization escape. This was particularly evident in the higher titre samples, which retained an average titre of ID50 680 against the RBD-only mutant.”

To define the location of dominant escape mutations, neutralization was also assessed against the RBD chimeric viral construct containing only three 501Y.V2 mutations (K417N, E484K, N501Y) (Fig.2a-middle).

A substantial loss of neutralization was also observed against the RBD-only mutant, with 27% of the samples losing all activity against the RBD triple mutants, while only 23% retained higher titres of ID50 >400.

These data provide more evidence for the dominance of Class 1 and Class 2 neutralizing antibodies in polyclonal sera. However, the differences in neutralization between the RBD-only chimera and 501Y.V2 also highlight the contribution of 501Y.V2 NTD mutations (L18F, D80A, D215G, and Δ242-244) to neutralization escape. This was particularly evident in the higher titre samples, which retained an average titre of ID50 680 against the RBD-only mutant.”

I think we really need to see whether or not there are significant numbers of people in South Africa who have already had the standard COVID-19 are re-infected with the new strain.  If not, we're good.  If so, we need an updated Vaccine.  

I believe it took the Moderna people 48 hours to design the current vaccine. Get workin', guys!

Just got an email from a vendor I do business with in China. They are in Xiamen City, China.

"We are going to start Chinese New Year(CNY) holiday end of this month/this week due to Covid-19 situation, workers will go home in earlier time.

There are some more new virus cases outbreak in the North of China places. We should be more care about it."

There's a warm fuzzy email a little over a year into this thing 

I've been to Xiamen for business.  I passed on the sea cucumbers at lunch...  Ate everything else though.

Everywhere is plunging.  As the Vax gets more and more rolled out these figures will continue to look better.  Dallas is reporting full ICU but the hospital beds are opening up behind them suggesting the ICU bed issue will be self clearing.  

This is over.

Super sad story.  I mentioned in passing one of my co-workers friend situation.

• Daughter goes to wedding (socially distant, right) comes back for Christmas.
• Dad flies to Florida to a retirement home! (yeah) notified daughter is + after visiting elderly father
• So elderly father gets in hospital and recovers without ICU stay, sent home maybe 10 days ago, but two days ago rushed to ICU with deep pneumonia and is not projected to make it.

These are the stories that will stay with us.  The deep and probably unspoken resentment of people taking calculated (stupid) risks, at the end of a pandemic.  It will haunt alot of families for a long time.  Don't be the last one to die in a war or a pandemic.  Stay vigilant.

Good to go on offense finally. 

I'm wondering how much of the declining numbers can be contributed to seasonality? Guess it seems kind of early to attribute declines solely to seasonality. Still good to see, and hope it continues.
