    The studies aren’t being reported accurately, from what I can understand.
    Both Pfizer and modera are still highly effective, even against delta.

    But if you have a weakened immune system, not as much.
    There are too many people with comorbidities or are older, who refuse to be careful, and like the 77 year old lady who just died after going on a cruise, are putting themselves ar risk.

    as i mentioned above, 30% of hospitalizations here are vaccinated. i would like to know ages and comorbidities of the 30% and 70% unvaccinated

    So I noticed publication date "JUNE 24, 2021", The article sounded more like 'could of been' and not so much on the technical aspects. I was looking for something that identified any different target mRNAs. Perhaps obvious, June 2021 was a local minimum for COVID cases as Delta had not fully kicked in.

    Just friendly feedback.

    Meet the new vax...
    Same as the old vax.

    Our local fake news is reporting unvaxed/vaxed hospitalizations is about 90/10.

    For me?
    90-percent is 'good nuff.'

    Better, in fact, than most....

    a lot of media outlets are doing nonsense stories just to stay in the limelight. even the liberal ones.

    if they only reported news, without opinion, they'd dry up like an old prune. we must have clickbait.

    the same story could be written about ivermectin, and in fact has been, by the alt news sites.

    The relatively lower death rate is partially due to better treatment with early mono-clonal antibodies. But it is pathetic to see such high rates while vaccine remains in storage ... no demand.

    The Delta variant isn't playing around....getting a LOT of people here in Colorado. Thankfully, I haven't heard of many deaths but many hospitals are filling up.
    Last week, my granddaughters daycare teacher caught it. (Our granddaughter is 3) Yesterday, she had a mild fever so got covid tested and found out it was positive this morning. Her Mom, a school teacher, was vaccinated over a month ago (both Pfizer shots) and isn't feeling good today and went in for a test.
    Stupid China flu is starting to piss me off!

    Well.
    It's OUR flu now, so we're gonna have to deal with it.

    OR....is the warp drive down for maintenance?

    It's kinda interesting which of the previous administration's policies were flushed completely and which ones remain largely unaltered.

    Microparticle sizes, 'hang time', and where they deposit are matters of interest. Here is a figure published in (journal) Science today:

    Microparticle interaction with lung system.jpg
    Here are some sizes to help understanding. A single naked coronavirus particle is 0.1 micron (um). They don't fly as singles and if they did, they would not remain infective for long. Instead they (often in large numbers) are entrained in water (one could say snot) droplets that are much larger. A 3-micron droplet can carry a lot of bad news. I've read that speaking and singing produce a lot of 3-micron particles. 'Wet' coughs and sneezes produce droplets up to 100 microns. Larger ones as well, but those fall very fast. After those quickly fall, you get exposed to them via fomites (remember fomites?) if you are not much of a hand washer.

    An N95 mask (worn properly) traps particles down to 0.3 micron size very well. 'Street' masks do not trap much below 3 microns, to my understanding. As typically worn they leak around the edges, but whaddayagonna do?

    MERV 15 air filters do not trap much below 3 microns either, but HEPA filters do. Mentioned recently in class project air filter post, but at that time I did not recognize parallels between face masks and big square air filters.

    On hang time:

    Better I think if authors of DOI: 10.1126/science.abd9149 had made the horizontal axis logarithmic as well. But anyway, the 3-micron example stays up for about one hour. If you are in a well-filtered indoor environment, or outdoors where 'advection is protection' :D , the crap mask you should be wearing has external help.

    Interestingly enough, indoors CO2 concentration can reveal how well ventilated it is. For the moment I resist going down that rabbit hole.

    i don't think it's that complicated.

    outdoors no masks, sparsely populated, almost zero risk

    outdoors densely packed no masks, fairly high risk

    indoors no masks sparsely populated, medium risk

    indoors no masks densely populated, high risk

    any mask in the above situations reduces risk, some more than others.

    vaccinated reduces risk

    it's not that complicated, and you can't apply one study to all the different possible permutations.

    local archdiocese is requiring masks in school this fall, but not in church o_O

    we had 1,900 cases in ma today, people are not paying attention. still, if hospitalizations don't keep increasing, we all have a right to choose our own risk.

    ^ Am I missing something or are schools no longer enforcing their own vaccine policies?

    I know in my own beloved home state of Indiana it was pretty simple....
    No shot card = 'a home schooler' with attention paid from the county to ensure that schoolin WAS happenin.
    Even their local Amish and the Mennonite folk took to vaccines in some, if not many cases because some of our civic leaders decided to communicate WITH them rather than yell AT them.

    Our local schools down on the Riviera operate in like manner, so immunizations for school kids just aren't a problem. We do allow for verified medical exemptions, and those who are opposed for 'other' reasons are simply not allowed to enroll their child in public or all accredited and most non-accredited private schools.

    @ Masks.
    Cloth masks are better than nothing....but they sure do not seem to stop perfume, smoke, etc....which is why they should be coupled with a little social distancing and a lot of empathy.
    If people who HAVE to work inside a store are all masked and they have a sign asking (or even TELLING) me to mask up....then I happily comply - but I do not treat cloth masks like crucifixes or keyfobs that generate tripedal rabbits.
    Non-N95 face masks are more like the 'outer tactical (Kevlar) vests' we wore in the military.
    They stop some of the stuff, some of the time...;)
    They were uncomfortable, somewhat bulky, a little on the heavy side, and restricted movement.
    They also generated a lot of sales for a company called....Anti Monkey Butt LLC.
    If you know....you know.

    HOWEVER (comma!)
    Tobacco smoke as it comes from a cigarette is an extremely concentrated aerosol with a 'relatively stable distribution of sizes ranging from 0.1 to 1.0 micron, peaking between 0.2 and 0.25 micron.'
    That's why fools smoke the darned things....it's a DELIVERY system.
    Second hand smoke is supposed to be deadly enough to require near-universal banning and public shaming of butt-heads, and mask Karens have NOTHING on Nicotine Nazis!!

    Isn't it funny how cigarette smoke blows right through masks? :unsure:

    ""Many clinics that give routine vaccines have been converted to giving COVID vaccine," Schwind says. "So in many places, the availability of the routine vaccines may not be the usual spot." Some families moved, or remained in online school all of last year, making it easier to overlook the state's vaccine requirements. And, Schwind says, in recent years, a growing number of parents have been applying for exemptions, citing religious, medical or philosophical reasons."

    As stated above....some states have no vaccine exemptions for religious or philosophical reasons. The religious exemptions are mostly balloon juice, since most people who are devout enough to eschew medical modernity want NOTHING to do with public schools and it goes without question that there are some school districts that fail at many things, both administratively and educationally.
    This is why there are sometimes long car lines at some public schools and school districts are prominently featured (for now) in MLS and other realtor ads.

    People with immediate or extended family in schools, either as employees or students find out about their vaccine (and other) requirements the easy way.....or the hard way.
    As far as 'other' vaccines, I had no problems locally getting geezer shots (pneumonia, shingles) and none of the littles in my life have had trouble accessing the 'usual' shots for this school year.....which started 3 weeks ago. One county is still in Hybrid mode, but I still had to contend with the usual troop of cheese wagons and parents dragging littles to school this morning during my long 3-mile commute to work.

    Many if not most people with school aged kids in their life are two income families.
    This gives them a financial stake in getting their kids to school........if and when they're open, that is.

    They usually find a way to get the required immunizations. ;)

    i wouldn't judge masks by what you can smell through them.

    first of all, their primary job is to block the outgoing, not incoming

    As far as I know, that's exactly how it's done—for respirators constructed to official standards and in workplaces requiring people to wear them because of hazards in the work being done.

    I guess that sort of describes the situation of a worker in a workplace that requires them for COVID. I'd say certainly for a healthcare worker who's going to intubate people, more up to interpretation for an office worker attending sales meetings.

    I don't imagine the performance of a homebrew mask is going to be much different for outflow than for inflow.

    I think most of us who are outside of healthcare work are (if we're interested enough) thinking about a Swiss-cheese defense model, and trying to wear something that adds one decent cheese layer we don't have without it.

    I think I would have to completely change my facial hair situation to have any hope of passing a formal fit test with a commercial N95 mask. I did make that change early in 2020 and keep it for much of a year, but shaving annoys me, and I've since reverted.

    Under my circumstances, I'm pretty sure my homebrew mask, which is larger and with ties rather than elastic loops, leaks a lot less than a commercial mask that doesn't fit well. I could do the double-mask thing as another layer of cheese; for now, my preferred other cheese layer is ... just not going out much.
