Yeah, but us sane people will appreciate it.
How long does the vaccine last for currently? How long for boosters as well? >

Answer for the last few boosters has been "wanes after 4 months, nearly gone by 6 months" but that's based on neutralizing antibody data. There's certainly some level of protection (against severe illness) even with low antibody titers. Super high titers really only serve to prevent you from catching it in the first place. >

Would it be easy to find out data behind those boosted within the last 4-6 months >

For antibody data sure, just simple blood draws in patients within different vaccination backgrounds (never vaxxed, first dose, second dose, 1st booster, etc). A big confounding variable is COVID exposure outside of the vaccines which boosts antibody titers in all populations. The more important data is going to be protection from death, severe disease and infection. That data is harder as it requires well-controlled trials (and ideally challenge studies). Yet another variable is what version of COVID do you look at. Maybe boosters worked great against delta, but not so much against omicron. In that case you have to make a lot of assumptions in the data: "patient X was infected and had moderate disease in October when such and such strain was dominant." Real world data is pretty messy and is even messier now than in 2020. Hence most studies stick to antibody neutralization studies. >

I meant more on a large scale. Is their any data of what % of Americans were boosted within the last 6 months. >

Oh CDC keeps tabs on that, so I'd expect they have that data. From what I've read the number is super low. Most people who want to get boosted mostly did so back in October/November, so they're (myself included) already on the downslope of waning antibody titers. And the overall number of people who even got their second booster is 4% lol. >

Why do you think it’s so low? >

So it was reported 4% at the end of September, 8.5% at the end of October. We don't have good data on the total number of people who have received two doses at present (many states aren't tracking how many boosters patients have received, just using no vax, original series, and original series+booster categories). Unless a ton of folks got a booster over the holidays, it's unlikely we're that much higher than 8.5% (maybe 15? 20 max?) >

Seems odd how went went from like 60% gun hoe to so low >

If I had to guess it's a mixture of fatigue, misinformation, as well as declining effectiveness. As an reference flu vaccine rates have fallen over time down to ~30% and that's only once a year vs every 6 months. The hope is either previous exposure to COVID or previous vaccination gives some level of lasting immunity so at least deaths/severe disease won't be as common, regardless of booster status. >

Nice, that's exactly where I was hoping we'd end up.
It'll just be another routine yearly vaccine we get, just like the Flu shot.  Look at what's circulating, give it the best estimate as to what strains to include, and get it once a year in the fall.
It won't be 100% effective, but it takes enough of the edge off when you do get inevitably exposed that you're not dying and hospitals aren't being overrun.
Hell, I hope it can just be included with the flu shot.  1 less shot to get, especially for the little ones (and us big ones) that hate needles. >

Moderna has been planning an all in one RNA vaccine that targets the major active flu variants and the COVID/sub-varients. They are talking about having it widely available within six weeks of determining the active variants. So they can make the vaccine in Sept. using the current variants instead of using their best guess in spring on what will be prevalent in the following winter. >

That's awesome to hear!  MRNA is a game changer and life saver. >

"Kha'ching," the cash register sings when profiting $100B  on taxpayer funded research isn't quite enough >

I don't think it matters the people who haven't done it by now won't regardless of what changes you make. And they surely won't be getting an annual shot.
