Anyone have any recent studies on the efficacy of boosters in preventing transmission? Just curious.
I was looking for the same thing. Not sure anyone knows at this point, given that so many cases are probably never diagnosed or never reported and any stats would likely apply to a previous variant or the one before that.Quote:

My reaction was also I would not used the word preventing, but rather, it has been shown that vaccination reduces transmission.
reduces, rather than preventing...
as goat has stated, if this was data from Oct2021 - Dec2021, it likely most applies to delta. maybe omicron(a) - remembering omicron was known to be 'immunity evasive'.
I still believe resistance offers reduced transmission, but omicron was so prevalent in January ( peaking at More than a Million positives daily... ), statistically, I don't know that it mattered...
I don't index the studies, but
might be able to find something in the posts from ,,, Feb15 (2022) through March (2022).
boostered x2
old. plus risk factors. skiJ
you still get covid but doesnt vax/ booster just protect you from getting really sick/ dying ?
it seems like ever buddy I know has got it this year
mostly it was just a mild- medium cold
Maybe, maybe not. Probably better protection than that for a while after a booster, but for how many will that be enough to keep it below the threshold of a positive test? Or symptoms?Quote:

The only study I've seen linked so far looking at 4th doses used a self-selected study group of HCW's and (probably/mostly) uninformed control group, so the people who wanted a 4th got one and they compared that with people who didn't want one (why? Already had omicron? Low perceived personal risk? Other? Unknown) to see how well it worked. That's not zero evidence, but it's really weak. Better would be better.
I don't believe the vax or vax booster prevents covid, but that it is more likey it will make Covid easier to handle
there is not much of a mask mandate up here in BC or Alberta when i was there last week, maybe one in Ten or less are wearing the mask
which is probably why everyone is now getting COVID, things have been canceled cuz there was not enough people to run a business but I havent heard about many deaths
Beer bro/ ski bro/ retired MD always gives me the heads up on whats happening so I'm waiting for the word on #4
First this:

[insert scratching head emoji]
I'm betting there are so many sick people on the show they can't recordr\ it
up here they had to cancel the ferry to haida gwai cuz there wasnt enough staff to run the boat and one other public transit I can't remember
Is there something special about Colbert's case? I see people fixated on it in the media and here, but it seems like dude just got COVID. What am I missing?
I wonder if he's still testing positive --
so with the disclaimer that we have at least two additional strains ( omicron ), I still believe there is value in vaccination ;
last year's, studies showed vaccination was +90% effective at preventing "severe covid ( requiring hospitalization)" even more than six months after vaccination, and that boosters bumped the antibody response such that immunity raised from ( high40s% and low60s% ) to upper80s% protective against testing positive
( late 2021, these studies were prior to the prevalence of omicron. data from July2021 through September2021 - posted in October2021/Novmeber2021 ) ;
omicron changed the picture, but by November 2021, a lot of north america had vaccination rates above 50% ;
though omicron has been determined to be 'immunity evasive', I don't believe vaccination was without benefit, even with omicron ;
I've been tracking cases since February, and though weekly deaths are down to 2000/week, there are still 2000 people weekly dying with covid.
I'm not trying to change anyone's mind anymore, and I am going to continue to promote vaccination - And I am going to continue to take steps to reduce my risk of exposure.
The value of vaccination in reducing the transmission of covid does not get enough consideration - we still consider this as an issue of / matter of individual immunity -
with almost a Million dead in the usofa ,,, I don't believe history will be kind.
I have friends who are unvaccinated, and they will continue to be my friends, but we aren't skiing together, and we aren't fishing together
( My risk management decision ) ...
Maybe next year.
we caught a break that omicron is not more pathologic / does not have a higher fatality rate.
thanks for listening... skiJ
Your beliefs are up to you, I don't wanna get all wrapped up in that. More likey more goodie and all.Quote:

If you hear back before an answer gets posted we'll save you some boiled meats for your trouble. Maybe $.37 is preferred if you've got BBQ around, though.

You being Canadian and all I figured we'd need some smaller denomination since nickel change got rare. Pocket meat?Quote:

actualy we don't have pennies anymore so there is no change for a nickel but i could just cut one in half for ya ?
You guys are hard core, man. Cut nickels sound like they'd have at least 4 points. Probably sharp. Tell ya what, we still have em down here, so if your guy finds the science first you post it up and I'll send ya change.Quote:

She took a bunch of Binax tests, all of which were negative. Went to Urgent Care the third day because her throat was so sore she was having some trouble breathing, and got tested for flu, strep and bronchitis. All negative. Got some steroid and it cleared in a day or two.
Thoughts? Maybe that was Covid and the tests didn’t pick it up?
I came back positive on a rapid test in like 2 minutes

I had a bad sore throat the past few days and tested negative (PCR). There are a lot of other bugs out there.
