Updated CDC guidance says 3 feet of physical distancing is safe in schools

Ask your wife. I understand that she was a teacher before retiring. She may suggest the possibility that if you only have to space the desks three feet apart instead of six feet apart, you can fit more desks, and therefore more students, in a classroom. It is at least a possibility.

Don't kids sit closer than 3 feet?  I don't see how that changes anything.

What?

Do they sit closer than 3 feet?

He compared the proposed penalty with data from ten years ago. How does that help?

I think you have to have sentences relative to the crimes.  You shouldn't send a pickpocket to jail longer than a guy who commits armed robbery.  Of course, no one should go to jail because you find them "annoying".  Go home and have a beer and lighten up.

Well, maybe someone measured the normal distance and saw it was 3 feet.  Now they can open the schools yet make-believe they still have a rule.

Don't condescend to me, Klein. You're obviously one of those who think rape can be trotted out to be used as a cheap comparison to any other crime. Some of us with more experience think differently.

Updated CDC guidance says 3 feet of physical distancing is safe in schools
https://www.cnn.com/2021/03/19/health/cdc-physical-distancing/index.html

6ft or 2 m distance has been recommended from the beginning of the pandemic as the gold standard.
However, in many situations even a 1m distance, especially for a short duration may be sufficient and of course, 3m or further is safer than 2m.

Quote
Physical distancing helps limit the spread of COVID-19 – this means we keep a distance of at least 1m from each other and avoid spending time in crowded places or in groups.

Quote
The number of droplets produced by various activities (coughing, sneezing, breathing, phonation, etc.) is very variable. By using a laser light scattering method, 1 minute of loud speaking was estimated to produce thousands of fluid droplets from the oral cavity per second; of these, at least 1,000 droplet nuclei contain virions, and under the conditions of the experiment, they could remain airborne for more than 8 minutes. Notably, patients infected with influenza virus exhaled aerosol particles containing infectious viral particles more frequently after coughing than after a forceful exhalation. Individuals who produce much higher quantities of infectious aerosols may be more likely to spread infection and be responsible for the “super spreader effect” in which an individual is responsible for infecting an unusually large number of susceptible individuals. Other factors to consider in the spread of respiratory viral infections are the frequency of respiratory events, viral concentration in the exhaled fluid and its volume, and the duration of exposure to an infected individual. Because breathing and speaking occur more frequently than coughs and sneezes, they could have an important role in transmission of viral infections, especially from asymptomatic infected individuals.

Larger droplets settle quickly, whereas small airborne droplet nuclei are transported over longer distances by airflow. The distance droplets traverse depends on how forcefully a person coughs or sneezes. Large respiratory droplets containing pathogens like influenza can travel approximately 6 feet when a sick person coughs or sneezes. The aerosol expelled from the mouth during a cough emerges not as individual droplets but as a jet with a leading vortex that has properties similar to those of a puff from a pressurized metered-dose inhaler and can penetrate an impressive distance into the surrounding ambient air before finally dissipating. Thus, emissions from coughs and sneezes contain droplets of various sizes suspended in a multiphase turbulent buoyant cloud. Turbulence sweeps around smaller particles, and eddies within the cloud resuspend the particles so that they settle more slowly, with some particles traveling more than 8 feet horizontally through the air. Moreover, smaller droplets could spray 13–20 feet vertically in the air, which is theoretically high enough to enter and travel through ceiling ventilation systems in some buildings.

It changes the topic of a discussion thread away from its purpose. That appears to suit those that have nothing useful to contribute and need something else to discuss.

The question, in a school environment, where kids sit next to one another and cough on each other and chat with each other before and after, how does three feet change anything?  It might as well be 0". It seems like a sop, just something to satisfy politically without having any bearing on the spread of the disease.

This is exactly what this thread is about.  Discussing the benefits of different suggestions to help eliminate the spread.  Are we only to agree with the poobahs? Should teachers and others who are exposed to the new variance accept them without question and risk their lives because you think we should all fall in line?

The topic of the thread is "Promising New Coronavirus Vaccine". The initial post was about the Novavax vaccine, the "Promising New Coronavirus Vaccine" in question. We have strayed far from the topic. TechTalk has listened to Josh's request and is trying to steer us back on topic.

Yes. In addition, Chris Kern, who started this discussion topic, also brought in the J&J vaccine for discussion. That's the topic "Promising New Coronavirus Vaccine" — Novavax, J&J, perhaps others in trial or rolling out.

It's not uncommon that someone diverts a topic for their own agenda. They then wait for others to take the bait. Their stinky cheese just sits in a trap to promote whatever they would prefer to discuss. I'm not looking to be their mouse.

I suspect Alan and I are in (rare) agreement that a prison sentence of any sort for protest or demonstration is not compatible with a free society. The comparison with rape is relevant, as you are perfectly well aware, because of the discussion in the UK recently about the right to demonstrate against male violence following the murder of Sarah Everard.

Why Johnson & Johnson’s one-shot Covid-19 vaccine is a game changer

March 1, 2021 - The vaccine is very effective — and most importantly, it only requires one shot.

https://www.vox.com/covid-19-vaccine-johnson-and-johnson-coronavirus

Excerpts below...

One big reason to be excited about the new Johnson & Johnson vaccine for Covid-19, which was authorized by the Food and Drug Administration over the weekend for emergency use in the US: Unlike the Moderna and Pfizer vaccines already in use, it requires only one shot for full protection.

That’s a big deal. From a practical standpoint, it means that the new vaccine could really speed up America’s vaccination campaign — certainly more than another two-dose vaccine would. It also fixes a problem that’s long bedeviled medical treatments that require multiple doses: A lot of patients tend to drop off after the first appointment.

“Especially when you’re trying to think about a massive public health program like this vaccine rollout, a single-dose vaccine would have made it much, much simpler” if it were the first to get approval, Amesh Adalja, a senior scholar at the Johns Hopkins Center for Health Security, told me.

Based on research that evaluated compliance with other multi-dose vaccines, patients are really, really bad at getting their second dose. Bad as in, as many as half of patients never do. Studies conducted in both the US and UK on the hepatitis B vaccine — which, like the Covid-19 vaccines, is supposed to have around a one-month period between the first and second doses — found that roughly 50 percent of patients failed to get their follow-up shot within a year after their first.

Maybe the numbers will look better for the Covid-19 vaccines. The stakes of a deadly pandemic are much higher, and perhaps people will react accordingly. But if a significant number of people fail to get their second shots, and the first dose of Moderna’s and Pfizer’s vaccines proves to not be enough, that could doom the prospects of herd immunity, when enough of the population is vaccinated to stop the spread of the virus.

One of the most obvious benefits to a one-shot Covid-19 vaccine is it could dramatically speed up — literally double — the US’s vaccine rollout.

Now imagine that the US manages to get to 3 million shots a day (which no longer seems unlikely). At that rate, two-dose vaccines would get us to herd immunity at the end of the summer, and a one-shot–only approach would get us there before summer. If one-third of vaccines are one-shot versions, we reach herd immunity by mid-summer — leaving the rest of the summer to, hopefully, live much closer to normal than the last year.

But the numbers, at least, demonstrate the potential of a one-shot vaccine like Johnson & Johnson’s. It could speed up the vaccination process in the US by weeks or even months.

With thousands of people still dying every day from Covid-19, that boost could translate to upward of tens of thousands of lives saved.

The Astrazeneca vaccine has been in the news. Some countries suspended its use because of concerns over it causing blood clots. The European Medicines Agency has deemed it safe, but there is some concern that the public may have lost confidence in it.

https://apnews.com/article/eu-regulator-review-astrazeneca-shot-blood-clot-links-437190969ed016e40bdfcbb4b63fc7a9

The US is going to "loan" 4 million Astrazeneca doses to Canada and Mexico.
