They're still on the job. I just had one of my posts deleted. I broke no rules, I said nothing political.
I thought opinions were just that, opinions.
apparently.....They're not.

Join my club. Nothing I was locked out for was political either. Just links to press conferences that showed what was being said at the top.

Probably get a real ban for that tidbit.

shortbus and I have already PMed one another on this subject before. He's on one side of the aisle, I'm on the other.
Still haven't changed my mind on what or how I believe.
I think it's from being born in the south.......Hard headed, we are.

Missouri (Show Me State) is not technically in the South. But, it is very hard headed. Tried to buy spinach at an IGA in suburban STL in the early 70's. Was told, it aint't grown here. We don't have it.

So, which state are you from?

@jpanhalt
Bet if you ask for grits you'll get the same answer.
Let's just say shortbus has some good points on certain things. I'm not opposed to everything the other side has to offer.
We should all listen to another's opinions even if we disagree with it.

This is really, really bad news:


... a physician in New Jersey has claimed that at least two of his Covid-19 patients had recovered from and tested negative for the coronavirus for months, but then started again experiencing symptoms of the disease and tested positive. One of those patients began showing symptoms of Covid-19 again after attending a party. "So that is … reinfection," the doctor said.

The physician said the second recovered patient who appeared to be reinfected was a family member of the first patient. According to the doctor, that patient had tested negative for the coronavirus for several weeks, and even had developed enough antibodies to the virus that he was able to donate plasma for experimental Covid-19 treatments before again experiencing symptoms of the disease.

But despite the anecdotal reports from doctors about patients becoming reinfected with the coronavirus, researchers say there's no evidence supporting the notion that people can become reinfected with the virus within a short time period.
I would say this is rare (small numbers are naturally immune and others will not develop immunity) and will have little effect either way on the course of the pandemic.

https://www.technologyreview.com/2020/08/11/1006366/immunity-slowing-down-coronavirus-parts-us/
The large number of people already infected with the coronavirus in the US has begun to act as a brake on the spread of the disease in hard-hit states.

Millions of US residents have been infected by the virus that causes covid-19, and at least 160,000 are dead. One effect is that the pool of susceptible individuals has been depleted in many areas. After infection, it’s believed, people become immune (at least for months), so they don’t transmit the virus to others. This slows the pandemic down.

“I believe the substantial epidemics in Arizona, Florida and Texas will leave enough immunity to assist in keeping COVID-19 controlled,” Trevor Bedford, a pandemic analyst at the University of Washington, said on Friday, in a series of tweets. “However, this level of immunity is not compatible with a full return to societal behavior as existed before the pandemic.”
Natural infection also turns out to be extremely efficient at reducing virus transmission—even more effective than an equal number of people getting a vaccine. The reason is that the virus has been finding and infecting precisely those people who—whether because of behavior, circumstances, or biology—are most likely to be part of transmission chains.

Perhaps they are college students on spring break, or hospital nurses, or people who touch their face all the time. Whatever the reason, once these individuals become infected and are removed from the equation through death or immunity, the effect on the pandemic is outsized. By contrast, vaccinating a sheltered older person might protect that individual but does relatively less to stop transmission.

While probably true, let's hope the anti-vax crowd doesn't make that a demand for the next protests. Natural infection also leads to more disease, morbidity, and death than an equal number of people getting a vaccine with few exceptions.

The story of Oral Polio Vaccine (OPV) is an example of a vaccine that today probably causes more morbidity than natural infection. Salk (dead virus) vaccine was less effective than Sabin OPV (attenuated virus). Early on, most countries adopted the OPV. In the latter stages of eradication of polio, however, Sabin vaccine became the most common cause of paralytic polio and hasn't been used in the US since 2000. (Note, OPV is still used in some areas. One reason is ease of administration in underdeveloped areas.)

https://www.virology.ws/2015/09/10/why-do-we-still-use-sabin-poliovirus-vaccine/
A breakthrough in our understanding of vaccine-associated paralysis came in the early 1980s when the recently developed DNA sequencing methods were used to determine the nucleotide sequences of the genomes of the Sabin type 3 vaccine, the neurovirulent virus from which it was derived, and a virus isolated from a child who had developed paralysis after administration of OPV. The results enumerated for the first time the mutations that distinguish the Sabin vaccine from its neurovirulent parent. More importantly, the genome sequence of the vaccine-associated isolate proved that it was derived from the Sabin vaccine and was not a wild-type poliovirus.

<SNIP>

After the WHO began its poliovirus eradication initiative in 1988, the risk of poliovirus importation into the US slowly decreased until it became very difficult to justify routine use of OPV. In 1996 the Advisory Committee on Immunization Practices decided that the US would transition to IPV and by 2000 IPV had replaced OPV for the routine prevention of poliomyelitis. As a consequence VAPP has been eliminated from the US.

OPV continues to be used in mass immunization campaigns for the WHO poliovirus eradication program, because it is effective at eliminating wild polioviruses, and is easy to administer. A consequence is that neurovirulent vaccine-derived polioviruses (VDPV) are excreted by immunized children. These VDPVs have caused outbreaks of poliomyelitis in areas where immunization coverage has dropped. Because VDPVs constitute a threat to the eradication campaign, WHO has recommended a global transition to IPV.

The anti-vax crowd doesn't matter. Conspiratorial thinking and government mistrust seems to have made them a lot wiser on the narrow case of Covid-19 countermeasures than the young and party animal crowd.

"Risk compensation" comes to mind. While I disagree with a lot of the mandated measures, like face masks, prohibitions on indoor dining in small parties, school closures, you can't cure stupid. Some people just can't understand reasonable measures. They have an irresistible need to expose themselves and others to unreasonable risk.

How much does media attention play? I suspect it is a large part. Somewhat like those who licked ice cream at Walmart last year for YouTube exposure.

On a more pleasant note, your video link had a link to "Adrift on the Air."
Consider an indoor contest where you don't even know whether you are competitive until your model hits 30 minutes! All with rubber band power.

IMHO, until the majority of the populace disagrees strongly with @jpanhalt, things will continue to get worse. It’s fairly obvious that countries that also disagree with jpanhalt are the ones with the coronavirus under control.
