You all be careful out there today. Watch out for the Wuhan cloud monster waiting outside your doors.
They probably changed it because people were trying to claim it wasn't a vaccine. When people try and take advantage of something seen as a loophole then it is wise to close the loophole. People need to get the vaccine
Is that a serious question? I'm assuming it is, but will admit to not looking into this thread for a good stretch, being sick to death (no pun intended) of reading the utter nonsense, largely political, from the "anti-vaxers." The various vaccines, produced using newer methods compared to those that typically took years to develop in the past, tend to have their potency wane after several months. Of the two principal vaccines in our country, the Pfizer and Moderna vaccines, after 6 months or so they begin to lose potency, the Pfizer noticeably faster than the Moderna (an extensive study showed that), but both gradually. The booster "boosts" the potency right back up to what it was for those 1st several months. It's not as large a dose (or "jab," as the Brits call it). The Moderna's (what I received) being exactly 1/2 of each of the two initial doses that were spaced apart by 4 weeks (3 weeks for the Pfizer). I had my booster a few days ago, and while I felt lousy for a day or two, with a sore arm, it didn't bother me as much as the 2nd initial shot, the "worst" for me. Many don't get much of a reaction to the vaccinations at all, some do. I was in the "some do" group. Not that big a deal, not really.
It is. How is it proven to boost potency when that study I quoted claims vaccines are more effective than natural infection? That doesn't sound like it "lost potency". How do they measure "potency"? Do you see what I'm getting at by "proven"? I'm not an anti-vaxxer. More of the concern that we hold stockpiles of vaccines to the point of letting them go unused and expired. The rest of the world is using Chinese and Russian varieties or being willing labrats for hydroxychloroquine or de-licer medicine. We're busy pointing fingers at each other when hospitals are starting to declog from overweight idiots clinging onto their last free breath of air. So I'll openly question the need for a booster. I'm totally for the 70-over crowd getting them, but I strongly suspect the Admin is pushing this as a "do-something" measure to provide a theater of safety. I read the formula didn't change for boosters, while a doctor at a hospital told me they did change it and it's mostly for Delta and older variants. So I don't ****ing know what's going on for an obvious no-brainer that you implied it should be. Details are pretty crucial...
If it's details you're looking for you definitely won't get it from them. They tend to make it up as they go. The narrative changes almost daily.
You don't believe that, do you? This is akin to all the videos showing that vaccine receivers were magnetized.
Unlike you who make it all up, once at the start, and then sticking with your story, despite any facts on the ground.
I fit the "over 70" crowd you referred to. As for "stockpiles of vaccines to the point of letting them go unused and expired" existing, that can largely be blamed on the incompetence of various state governments, including our own here in Texas, in advertising both the need to get vaccinated, the availability of the vaccines, including where to get them and that getting them is free, and the constant barrage of politically motivated BS designed to discourage getting vaccinated from politicians who are attempting to suck up to trump and trump supporters. In my opinion. After all this time, if you don't understand that, I genuinely don't know what else to tell you. The information is out there, in spades. The effort of the state government under Abbott to undermine confidence in the vaccine and getting vaccinated is obvious. It's not being hidden from anyone.
Reduce the rate of severe disease in breakthrough infection. 1- protection against infection was waning 2- a good number of people have an immune deficiency (more likely to be infected, more likely to face severe disease) 3- older and "sicker" folks have a higher chance of severe disease when they get a breakthrough infection 4- breakthrough infections do spread An argument against booster for "healthy": Although antibody/protection against infection wane, memory B cells CONTINUE to increase between 3 and 6 months post-vaccination. This explains why while breakthrough infections are increasing with Delta/time, protection against severe illness has not waned, in a recent Canadian study, has even increased for ALL age groups (I can't find a link to it now but I read it about 2 weeks ago). As for the CDC study that vaccine provides 5x better at protecting against infection than "natural" immunity, I believe I replied to it in another thread. BTW, "natural" immunity is somewhat not accurate - in both cases, your body "naturally" develops some level of immunity to covid from infection of the virus or from vax. The CDC study itself said that the Israel study findings were different (natural immunity provide better protection *against* infection) and the reasons for that were possibly 1) CDC study covers hospitalized only while Israel covers all cases and 2) CDC study cover vax period from 3M+ while Israel covers from 6M+. Laboratory-Confirmed COVID-19 Among Adults Hospitalized with COVID-19–Like Illness with Infection-Induced or mRNA Vaccine-Induced SARS-CoV-2 Immunity — Nine States, January–September 2021 | MMWR (cdc.gov) These findings are consistent with evidence that neutralizing antibody titers after receipt of 2 doses of mRNA COVID-19 vaccine are high (5,6); however, these findings differ from those of a retrospective records-based cohort study in Israel,†† which did not find higher protection for vaccinated adults compared with those with previous infection during a period of Delta variant circulation. This variation is possibly related to differences in the outcome of interest and restrictions on the timing of vaccination. The Israeli cohort study assessed any positive SARS-CoV-2 test result, whereas this study examined laboratory-confirmed COVID-19 among hospitalized patients. The Israeli cohort study also only examined vaccinations that had occurred 6 months earlier, so the benefit of more recent vaccination was not examined. This report focused on the early protection from infection-induced and vaccine-induced immunity, though it is possible that estimates could be affected by time. Understanding infection-induced and vaccine-induced immunity over time is important, particularly for future studies to consider. mRNA vaccines induce durable immune memory to SARS-CoV-2 and variants of concern (science.org) These studies provide insight into the evolution of immunological memory following SARS-CoV-2 mRNA vaccination. Specifically, the continued increase in SARS-CoV-2-specific memory B cells between 3 and 6 months post-mRNA vaccination, even as antibody levels declined in the same individuals, suggests that prolonged germinal center reactions (14) continue to generate circulating memory B cells for at least several months following vaccination. Furthermore, there may be differences in immunity generated by mRNA vaccination versus infection, as memory B cells 6 months post-vaccination were qualitatively superior at binding VOCs compared to memory B cells 6 months after recovering from mild COVID-19.
