Stargazer Posted February 21, 2021 Posted February 21, 2021 1 hour ago, Rain said: If you get more/stronger symptoms depending on how many virus enter your body then maybe this happens because older people are more likely distance and fewer in their body? I have no idea if the science of the vaccines work that way or not, but if it does then the social distancing before of the person may explain that. It would be interesting to see if there is a difference in young and old care workers in covid units in the hospital. I understand that the amount of the actual virus that enters one's body does determine some aspects of the progress of the infection. For example, how quickly symptoms become apparent. The particular vaccine I received is of a mRNA type, which means that no actual virus, either killed or attenuated, was administered.

Right, but do the symptoms from having the vaccine come from the vaccine or do they come from the vaccine interacting with the virus or both? It seems from people having had covid before having some stronger symptoms that maybe it comes from both the vaccine and the interaction? Edited February 21, 2021 by Rain

It seems from people having had covid before having some stronger symptoms that maybe it comes from both the vaccine and the interaction? The vaccine works by presenting the immune system with an inactive "sample" of the virus or simply a portion of the virus so that the system learns to recognize the actual virus. And since it believes an attack is in process, it creates antigens which would attack the virus (which you don't feel). But along with that, the system also reacts with the tools that are part of the general response to infection (whole-body fever and inflammation around the injection site). It is as if you were infected with the actual virus when you were not. Of course, it's entirely possible for someone to already have been infected with the covid virus very soon before the vaccination, so they might seem to have developed full covid from the vaccination, but it would be a coincidence. It is also coincidentally possible for someone to become infected with the real virus very soon after the vaccination, and the same thing would seem to have occurred. It takes some days for the vaccination to take full effect. I read a National Insitutes of Health article which said those who had already had covid would probably react to their first covid vaccination as strongly as others might to their second vaccination. And that they might not need a second vaccination. 1

That could be taken care of by people saying saying "32.5", but in my limited experience people don't do that unless we are talking about things scientifically. I never used to feel that way till I got to Arizona. Now if the temps start reaching 114 (we have hit 113 every year I have been here) or 122 (record breaking) it is nice to tell myself "of course I am hot" or fun to "brag" about it to others. If we ever hit 123 then 50.5556 just doesn't have the same ring to it.

I have our meteorology app on my phone, and our current temp is 13.8C. There is little reason to report fractional Fahrenheit degrees, because the difference between the freezing point of water and its boiling point is 180, but the same range in Celsius is only 100. So each Celsius degree is nearly 2 Fahrenheit degrees. And for some purposes in Celsius, the fractions matter, such as for fever. I'm getting steadily more used to Celsius here in the UK, but I'm still not quite acclimatized to it. Edited February 22, 2021 by Stargazer

Of course, a British imperial pint, at 568ml, is considerably larger than the American version, which is only 473ml. I don't think many Americans realise that the US imperial system of measuring volumes long ago diverged from its British ancestor.

Calm Posted February 23, 2021 Author Posted February 23, 2021 (edited) More good news with some bad news: https://www.ksl.com/article/50112384/this-is-really-truly-remarkable-primary-childrens-hospital-reports-historically-low-rsv-flu-cases Quote Respiratory syncytial virus, or RSV, and influenza have resulted in virtually no hospitalizations at Primary Children's Hospital. That's a welcomed surprise for pediatric specialists who typically deal with 80 to 120 RSV hospitalizations and dozens of intensive care unit stays per week on top of hundreds of yearly influenza hospitalizations. "This is really, truly remarkable," said Dr. Andrew Pavia, a pediatric infectious disease specialist with Primary Children's Hospital, during a press briefing Monday regarding the pediatric hospitalization trends for both viruses. The hospital has seen more cases of the rare complication from SARS-CoV-2 called multisystem inflammatory syndrome in children, or MIS-C, than either flu or RSV. It's estimated that about 75 MIS-C cases have been treated at the hospital over the past few months. Bold mine Quote Primary Children's Hospital still hasn't reported a single RSV hospitalization over the typical season. "We're seeing something that I've never seen in the last 35 years," Pavia said. "If you go back to history, it hasn't really occurred except briefly after the 2009 influenza pandemic." Then there's influenza, which often affects hundreds of thousands of Americans every year. So far, the Centers for Disease Control and Prevention has only reported a little less than 1,600 total confirmed flu cases in the U.S. as a result over nearly 1 million tests. The CDC reports that all 50 states and Puerto Rico have "minimal" flu case trends. In fact, fewer than two dozen new cases were reported in the most recent week. These are similar nearly unheard of trends in Utah. The Utah Department of Health's weekly influenza dashboard shows there have only been 13 total hospitalizations due to influenza through Feb. 13. There were 1,310 total influenza hospitalizations last year. Pavia said there has been one pediatric hospitalization as compared to "several hundred" that normally would happen at this point in the flu season. Quote RSV is going to do something really strange when it comes back," Pavia added. "We really can't predict it very well. Our gut feeling is that it will come roaring back and that we'll have a bad RSV year when it does return." I get the feeling this past year and at least several to come will become the focus of numerous dissertations for up and coming epidemiologists. Not only studying the weirdness of Covid with children, but how the reactions to Covid affected how other diseases manifest. We could be learning so much on what works, what doesn’t, unintended consequences...hopefully funding will be there for figuring out the whys as well as improving vaccine technology and treatments.

"So while it might have been revved a little bit with this partial dose that was kept at a different temperature, what it's doing is re-exposing your system to a piece of that virus."
