      The study was published in The Lancet Infectious Diseases journal, a highly respected source, and this story is from https://on.rt.com/bjv0 . I don’t see it in US sources yet.

      A new study has found that though Covid-19 vaccinations lower the chance of hospitalization and death in the case of infections, those inoculated can spread the Delta variant as easily as those not.

      Researchers looked at over 600 people in the UK over the course of a year for the study, done by Imperial College London and the UK Health Security Agency (HSA) and published this week in The Lancet Infectious Diseases journal.

      “Although vaccines remain highly effective at preventing severe disease and deaths from COVID-19, our findings suggest that vaccination is not sufficient to prevent transmission of the Delta variant in household settings with prolonged exposures,” the study declares.

      The study also claims that the viral load, the amount of a virus in one’s body, is similar among the vaccinated and unvaccinated, though the virus dissipates quicker in vaccinated individuals, according to the findings.

      This looks like the article if you’d like to read the article directly. It was published yesterday.

      why vaccinate at all?

      Well, this comes from an article here in New Mexico:

      ALBUQUERQUE, N.M. —COVID-19 cases and hospitalizations are going up in New Mexico, despite mask and vaccine mandates in place.

      On Thursday, the state saw its highest single-day total since January.

      However, it also points out the obvious:

      Since the vaccines came out in February, 82% of New Mexico’s cases were in unvaccinated people, along with nearly 87% of hospitalizations and more than 93% of deaths.

      And here is the kicker:

      Yet things aren’t as locked down. Thursday, the state reported more than 1,309 new COVID-19 cases – the highest single-day total since January. Hospitalizations are also trending upward. Gonzales said their ICU is above 100% capacity, but she is noticing a shift.

      Assuming that the vaccine doesn’t work is highly speculative. Define ‘doesn’t work’. If it is to prevent catching the shit, then that’s one discussion but if it’s to minimize transmission and effect, then that’s totally different.

      One thing that’s always sort of reported, but really, is the hospitalizations part of this equation. That is a highly important stat since March before last. Associated with that stat is the number of deaths due to limitations on provider services and material. We have pretty much zero info on that.

      What we do know is that virtually every ICU and CCU bed in New Mexico is taken.

      If you get in a car wreck, you in big trouble. If you get a heart attack, you in even bigger trouble. We either get these hospitalization rates down or the stats from deaths due to insufficient medical availability is going to sky rocket.

      Transmission is not prevented by vaccination, but by correctly using masks, hygiene and distancing.

      I believe that it’s a matter of time for this virus to reach 100 percent of us. It’s what we do in the meantime that counts.

      My own way of dealing with the transmission issue is to douche my oral/nasal pharynx with salt water and baking soda/warm water after having to deal with the outdoor public, even after wearing an N95 mask.

      Hell, no... I'm not giving up...

          Beats the shit out of me, Voltairine. But, it demonstrates pretty well how effective aerosolized particle sizes can leak, for sure.

          But, breathing out and the transmission of droplet nuclei during a human’s exhalation consists of N2/O2/CO2 gas and mostly water vapor (molecular water) with some droplets from that tidal exhalation.

          It wasn’t very objective in showing how distancing and proper masking affects transmission.

          Hell, no... I'm not giving up...

            AFAIK N95 is US specific terminology, and according to Wiki:
            “It is an example of a mechanical filter respirator, which provides protection against particulates but not against gases or vapors.<sup id=”cite_ref-3″ class=”reference”>[
            https://en.wikipedia.org/wiki/N95_respirator

            The case demonstrated was that if a pathogen is transmitted through vapors/aerosols, distancing and masks do very little if anything to prevent transmitting. </sup>

            Aloha!

              The ability of an aerosol particle to remain suspended in a gas (stability) is influenced by its size, activity and concentration. Larger particles are more affected by gravity, but the kinetic activity of the aerosol will affect where that particle lands. If it’s less than 50 microns, it’s filtered out before it enters the respiratory tract. Sizes that are anywhere from 5 – 50 microns deposit in the mouth, nose and pharynx. There’s got to be a better bench experiment (that term is used loosely in this guy’s demonstration) than this video. Did the distance that these unknown sized particles travel before reaching the next body appear in this video? I didn’t see it.

              Hell, no... I'm not giving up...

                leaves out important information. That’s built in the standard notion of information.

      Have to be selective to ensure JPR doesn’t have fair use issues, but the above is also important!

      It’s as has been noted here recently – while vaccination doesn’t prevent COVID-19 transmission, it does help (“highly effective”) with severity and lowered risk of death.

      The problem was always that our lousy health system got

      overwhelmed. Once I get my J&J booster I would like to

      get the COVID infection as long as I am still in reasonably

      good health. No matter what Pfizer claims the natural

      immunity is stronger than the one produced by the vaccine.

      is that the vaccines reduce the severity of the disease without eliminating the virus. This means that the virus gains a host that allows it to continue – and time to mutate. If allowed to mutate a virus will eventually find a mutation that is either benign to the host or is able to overcome the vaccine – either a “safer” strain or a more deadly one – the Delta variant.

      fail to speak about mutations which as I understand it is a significant factor in why it is hard to dampen this beast.

      I will continue to mask up and avoid public places as much as I can but sadly have to do all the shopping here by myself in an area that is a Frump stronghold and antimaskers. I will perhaps get the booster but am waiting for more information. This is not something to be messed with or taken lightly.

      Animals know more than we do.

      What they prevent is death and disability from infection.

        As has been shown in articles on this site. The couple in Michigan and Colin Powell died of Covid after being vaccinated.

          Colin Powell was 84. He had multiple myeloma, early stage Parkinson’s, and a compromised immune system. As for the Michigan couple, as the saying goes, “The plural of anecdote isn’t data.”

          –therefore he could not respond to the vaccine.l  No evidence whatsoever that it hurt him.

      And it also boosts their immune system to the point that successive variants are even less of a threat, and in effect just provide a natural booster shot to those that get it.

      Then we can sit back and enjoy the theories that the Delta variant wasn’t natural, but was instead released because our corporate masters have demanded of government that we get back to work. 😉

      All kidding aside, IIRC it was considered plausible that COVID-19 would evolve into something more contagious, but less lethal, as a virus that didn’t impede people being out and about and spreading it would have an evolutionary advantage.

      We need an Epsilon variant, perhaps from Portland, that is totally laid back and content to do just enough to earn its keep/name while focusing on enjoying the finer things in life. 🙂
