I'm not going to go into details, mainly cos it makes me so angry to sit reading it for any length of time.
Also, the bespoke model leaves me dumbfounded. What follows are generalisations, mainly because this is basically an iteration of the 23 model, where this attrition began.
First, yet again, the focus, or rather the most favourable cost-effectiveness, is avoiding deaths and acute hospitalisation.
Of course, this is critical, especially as we still do nothing to mitigate uncontrolled prevalence, and I include effective vaccination in this regard.
There're dozens of the usual platitudes, including the magical "endemic". In my opinion, these are little more than misinformation, including the soothing balm of infection-induced immunity.
Yet, despite trying to prevent deaths, the survivorship bias here isn't mentioned 💔
Another "triumph" in this regard is that eligibility for vax is now narrower than for antivirals, H/T @cv_cev ...
So, treat, but don't prevent?!
How wonderfully cost effective, both in terms of 💰, and people's SMEGGING lives...🤬🤬🤬
Yes, hospitalisation rates are lower than the previous year, mercifully, but do they ever wonder why?
Immunity is, of course, a huge beneficial influence. But, so little is from recent vax that "cost", in human terms, keeps going up.
Basically, vulnerable folks keep dying, ffs!
Moreover, there are so many papers extolling the virtues and benefits of vax for 6m-5 Yr, I've lost count, but this recently from @chrischirp @katebrown220 et al is great.
Comparing adult to juvenile disease has long been fallacy, yet it continues 🙄
Before we get the kids are fine/invulnerable, Us4Them 💩...
Acute COVID risk 3 u18 is U-shaped. 6m=highest, decreases to inflection point at ~5yr, then age related increases begin.
The case for kids vax needs more than tweets. See here if interested.
There's the usual nonsense about hospitalisation rates being lower than the start of the pandemic...well, yes, of course they are!
But, we still have 1000s more dying and hospitalised than in 2019, multiple waves, uncontrolled virus evolution...yes, better, but NOT GOOD!
Of course, now things ARE better, the plan is to take away the stuff that got us there! Bloody wonderful...
Despite brilliant juvenile vax with virtually no SAEs, we'd rather bet our future population immunity on a dangerous virus that outpaces immunity every 3-4 months...🤦♂️🙄
But, and this IS a big but, these things cost money, a lot of money, and I'm sure that there are sums that justify only paying for over 75s with this in mind.
But, and this is a BIGGER But, cost always balances against savings. I'm pretty sure they're missing a lot of these!!!
The focus on acute issues from COVID has permeated UK policy since the beginning. But now, #LongCovid accounting for many on long term sick, this STILL doesn't factor, somehow. It's almost 2025 ffs!
Neither does #LongCovidKids, or a raft of COVID juvenile and adult sequelae...
Cardiovascular, neurological, metabolic, autoimmune, autoinflammatory, and other conditions, all demonstrably increasing and affecting younger demographics.
NOT the vaccines (not perfect, obvs), COVID.
How much is a lifetime's supply of insulin for a 10yo diagnosed with T1D? 💔
At the risk of sounding like a broken record, a vaccine only strategy is more effective if you actually USE them...
The commercial price is insultingly high and discriminatory.
Vax + mitigation, reduced prevalence, exposure, illness, and evolution
Before I'm told to "move on"...
Getting the pandemic under control is, of course, additional to the health costs of endemic (so, clearly, not a problem? 😜) infections, where vax offers and mitigation are, shall we say, somewhat lacklustre...
JCVI FINALLY learned these lessons for VZV, why not other viruses?
We seem to value "normal" over better, especially if it's expensive up front, or gets in the way of "normal life"...climate change seems to get a similar reception...but, complacency, ultimately, is also a devastaring killer.
#VaccinesPlus
We have a very safe, efficacious paediatric SARS2 mRNA vax, used 6m+.
Reduced dose and age minimises small risk of myocarditis seen in adolescents.
This sobering study by @katebrown220, @chrischirp et al shows 6m+ kids are always at risk from acute COVID.
Maternal antibodies should help protect newborns during the first 6m of life, but this is optimal when mums are vaxd during pregnancy. Sadly, this only happens if your term coincides with a booster campaign 🙄, which is just plain daft. Highlighted many times by @VikiLovesFACS
The first exposure to a pathogen is always the highest risk, no matter what age it occurs.
Whilst kids tend to develop severe symptoms less frequently than adults, this is the wrong comparison and does NOT mean they are invulnerable.
Both short term and long term problems arise.
Sorry, looooong thread, but hopefully done soon!
Where was I?
So, let's say the small elite team of virus particles has survived the journey and landed where they want to be...
First, they will encounter innate barriers, eg mucus, which they must cross to physically reach a cell.
There will also be complement, mucosal antibodies (if host is immune), and these can both inactivate and clump viruses together such that phagocytic cells literally eat them up!
So, many of the hurdles from the way out also hit on the way in, and this time, numbers are limiting.
So, viruses need to infect their target cell as quickly as possible before they succumb to defenses.
This mainly depends on the affinity of the viral attachment protein for the cellular receptor used to gain entry. But you have to both unlock the door AND walk through it...
Lots of good debate about virus transmission, yet it's dwarfed by mis/disinformation and lack of nuance, allowing eejits to dismiss the precautionary principle, or, worse, re-run 1980s bigotted attitudes🤬
Viruses don't fit easily into boxes. So, nuances of transmission, a 🧵
I will focus on the example of airborne transmission, but the underlying principles apply to all modes of infection.
Caveat: I research the start/end of the transmission process, but the middle bit is not my forte, so forgive omissions/errors!🙏
See @ukhadds for added nuance!
Right, so I would define transmission as the transfer of sufficient infectious virus from a site of infection or environmental source to an individual, followed by the successful establishment of a productive infection (ie the completion of the life cycle) within the new host.
🚨Anti-vaxxers are twisting a study into mRNA armageddon.
TLDR, all this study says is IF certain groups experienced an adverse event COINCIDENT with vax, then it was more likely to be myocarditis than if taking a different drug🤦♂️
It's behind a pay wall, so will keep brief to save anyone having to read it to stave off the various nutters quoting bizarrely inflated risks of death etc...#LiedSuddenly
Expect it may feature in certain press and on a "patriotic" news channel before long 😉
So, in brief:
1. This is data from JADER, the Japanese equivalent of VAERS, yellow card etc.
Reports of adverse events COINCIDENT with a medicine are made by healthcare workers, pharma, public etc.
Main point, it's a sentinel system used to spot patterns, cases need verifying.
Some issues here...putting it mildly. 1. These are NOT the only high-risk groups. @CDCgov recommend >50s and children as a minimum. 2. This is an influenza strategy, we are NOT in the same place with SARS2 by a country mile. 3. Vax status by age is worrying, 1/3 u40s no vax 😬
4. % of kids u12 vaxd was only ~10% in 22/23 b4 offer was stopped... 5. We age, folks die, and are born. The % population covered by the emergency programme is therefore dwindling across all ages. 6. Yes, our protection vs severe COVID lasts way longer than vs infection, but...
7. Recent study in @JAMA_current shows more recent, better matched vax is better at keeping folks out of hospital. 8. Vax 4 just vulnerable helps en masse, sure, but many r unlikely to make a good response. 9. Poor responders amidst high prevalence will erode protection quickly.
So, the bugs that put me in hospital recently were multi-resistant E. coli. No oral antibiotics would work, so I was on IV for 8 days; 2nd line was looking challenging had the infection not responded.
#AMR isn't a new problem, but the can is continuously kicked down the road...
It's not the same as a pandemic, so I'm not sure about that comparison.
BUT folks need to be reminded that, pre-penicillin and other abx, any wound or infection could be life threatening.
#AMR is via part over-use, part misuse, part inadequate investment into R&D.
In the main, anti-infectives aren't generally looked upon as a good way for pharma to recoup their investment, particularly as new antibiotics tend to be held in reserve nowadays because of the dangers #AMR brings...
This isn't companies being "evil", there's no conspiracy...
