Dude. This paper you're sending me is saying exactly what I'm saying. My reasoning matches all of the papers you've sent me so far:
You're saying:
> "all the studies of infectiousness of SARS-CoV-2, and even of other respiratory viruses correlate with detection of high virus load in the upper respiratory tract"
But, RNA fragments detected by PCR in nasal swabs != live, infectious virus.
The paper you linked is saying, instead:
"Our study shows that despite evidence of prolonged SARS-CoV-2 RNA shedding in respiratory and stool samples, viable virus appears to be short-lived. Therefore, RNA detection cannot be used to infer infectiousness."
"Our findings suggest that, although patients with SARS-CoV-2 infection might have prolonged RNA shedding of up to 83 days in upper respiratory tract infection, no live virus was isolated from culture beyond day 9 of symptoms despite persistently high viral RNA loads."
Residual RNA from lysed cells is sticking around and getting picked up on nasal swabs even when actual, infectious, titers of virus in the body are plummeting, and patients are no longer infectious. I used to work with RNA in a research lab! The shit is everywhere. Our experiments used to get contaminated with RNA from the lab next door all the time. I used to have to spray my bench with a bleach solution every day, sanitize my pipettes, and work at night so my RT-PCR experiments didn't get contaminated. That's in the air. Imagine how long it hangs out in the moist, snotty environment of the nasal cavity.
"Nevertheless, most studies demonstrate faster viral clearance among asymptomatic individuals than those who are symptomatic."
"This finding is in keeping with viral kinetics observed with other respiratory viruses such as influenza and MERS-CoV, in which people with asymptomatic infection have a shorter duration of viral shedding than symptomatic individuals."
Giving these people a vaccine will help them clear the infection even faster, which will help reduce community transmission, especially in places where they're now wandering around without masks on, in full compliance with state law.
I'm happy that the UK is prepared to make aggressive and forward-thinking health policy. Good for the UK, but this ain't the UK. There are a lot of countries like the US where I live, as well as my neighbor Mexico that don't have an NHS, and don't live on a small island with a well-functioning government. These vaccines will help to reduce community transmission in places where the scenes from urban hospitals can best be described as nightmarish.
"No part of the world has been as devastated by the pandemic as Latin America. Mexico, Brazil, Peru and other Latin American countries — hobbled by weak health systems, severe inequality and government indifference — have several of the highest deaths per capita from the virus in the world.
And unlike in Europe, the United States and many other regions, the outbreak in Latin American has not struck in waves. It hit furiously in the spring and has continued for months, with few of the respites savored elsewhere, however briefly, around the world. By the first week of September, the 10 countries with the highest deaths per capita were all in Latin America or the Caribbean."

Again, shift your frame of reference. The rest of the world does not look like the UK and Europe. Enjoy living somewhere that isn't a charnel house. The vaccines reduce community transmission, and I can say that confidently because I have outlined a pretty clear mechanism for it and there is zero data you have presented that points in the other direction, despite the fact that you keep saying it. Celebrate that fact that we now have this tool in our arsenal.
I promise I'm not the enemy. I promise I'm not conjuring things out of thin air. I'm reading all of the papers you're sending me, and I'm drawing valid scientific insights from them that are applicable to the broader world-at-large, not just the UK with the NHS at the helm, which is able to take steps that for much of the rest of the world is an unrealistic luxury.
- acqq 6y agoThe paper, and the papers it references, disproves your wrong theory that you repeated many times in more messages on this page about "lower respiratory tract" being more relevant for virus transmission, which is still wrong, as in, completely the opposite of what is reported in the scientific papers. I show you the findings about upper respiratory tract, you then cite "respiratory and stool samples" sentence from the paper as if it somehow disproves what is supported by the paper and the ones it references, that the high viral load in the upper respiratory tract before symptoms and during the first days of symptoms is critical. You cherry pick the sentence about the "viable virus" not being present "beyond day 9 of symptoms" (meaning day > 9) but that doesn't disprove what is claimed in the studies: that the transmission occurs even before symptoms (days -2 -1 and 0) and during the first few days of symptoms, that is, before the host's immune system has the time to fight the virus infection. https://academic.oup.com/view-large/figure/210823252/ciaa1442_fig2.jpg https://academic.oup.com/view-large/figure/210823252/ciaa144... from https://doi.org/10.1093/cid/ciaa1442 https://doi.org/10.1093/cid/ciaa1442 The scientific facts aren't less true in the US than in the UK and Europe. Your claim that you "used bleach solution" in the lab also doesn't make your wrong theory and your other wrong claims less wrong. Of course PCR tests detect RNA longer than the infectious virus is present, but all studies I've cited haven't ignored that fact.
- phobosanomaly 6y agoCan you cite specific sentences from the paper that disprove my hypothesis? I pulled and quoted specific sentences so you didn't have to dig through the paper to see what I'm talking about. If I'm wrong, and the paper clearly says how I'm wrong, pull the specific sentences and show me. Then I don't have to dig through a research paper trying to guess what you're seeing in there that makes you think I'm wrong. I've outlined a specific mechanism, you can pull things from the papers and refute my mechanism line-by-line if you want. I'm not being vague about anything. I'm spelling it out pretty clearly. If I'm wrong, show me how I'm wrong and then I and everyone reading this will be able to see clearly how I'm wrong. > "I show you the findings about upper respiratory tract, you then cite "respiratory and stool samples" sentence from the paper as if it somehow disproves what is supported by the paper and the ones it references, that the high viral load in the upper respiratory tract before symptoms and during the first days of symptoms is critical." I haven't seen any other method of measuring viral load in the upper respiratory tract than PCR. Maybe I've missed something? But in the lower airway they're using lavage in live animals and tissue immunohistochemistry in sacrificed animals to determine actual viral load. So, we don't actually know viral load in the upper respiratory tract from nasal swab PCR specimens (since, as they mentioned in the last paper, PCR from nasal swab doesn't actually correlate with viral load). Do you know of a way that they're measuring upper respiratory tract viral load other than nasal swab PCR? The point of the bleach anecdote is to highlight what this paper said, which is that you can't estimate viral load based on nasal swab PCR since very high levels of mRNA hang out in the snout for long past the time when infectious viral titers have diminished.
