My new post takes a look at the topic of “immunity debt”

What does this term mean, and why has it been so controversial?

What explains the weird reemergence of seasonal pathogens since the pandemic?

Is Covid-19 damaging immune systems?

Let’s find out! 💥

"we haven't been able to give them the vaccine ... there hasn't been enough data for the regulators ... this trial is looking at getting this additional data that we need so that hopefully in the future we'll be able to offer the vaccine to children younger than two." - @apsmunro.bsky.social
Did you see @uhsft.bsky.social's @apsmunro.bsky.social on BBC South with @edwardjsault.bsky.social? 📺

While many people recover quickly, flu can be dangerous for young children.

A new trial is exploring whether the flu vaccine can be extended to younger toddlers.

"trials were immediately halted and a meeting ... convened on December 12th 2024. Despite the vaccine passing all the pre-clinical tests put in place to ensure the vaccines didn’t result in VAERD, it looks possible it may have happened anyway. ... the safety checks ... worked extremely well"

Just remembered when I broke one of my golden rules and suggested testing for Mycoplasma serology last week

This morning I awoke to discover we had run out of coffee

In behaviours not at all indicative of addiction, I drove immediately to the nearest drive-through Costa in my pyjamas to obtain flat-whites for me and my wife

I have no regrets

This equates to 0.5 micromorts for each person receiving a vaccination course (usually several vaccines)

That is less than the mortality risk for a single day of skiing (0.7 micromorts)
Covid vaccine deaths: the best data came out of Korea, which did autopsies on all post-vaccination sudden deaths.

The country identified 21 deaths out of 44 million vaccinees.

Yes people can die from the vaccine, but it’s incredibly rare.

This reminds me that contrary to some thinking, social media doesn’t reduce exposure to alternative viewpoints (eg “bubble effect”)

It increases exposure - but only to the worst and most extreme versions of them, further convincing you that you’re right and “the others” are terrible idiots
Whereas traditional media caters to a range of views, with moderate positions well-represented, extreme views — of both left and right — are heavily over-represented on social media. on.ft.com/3HNwX1M

We didn't randomize, and there was no allocation concealment or blinding, and we can't really be sure what intervention they got or how the outcomes were measured, but we emulated a trial by drawing a DAG.

There are a lot of oral/enteral source infections where we add anaerobic cover to standard empirical antibiotics (usually cephalosporins - classic “cef and met” combo)

Is there actually any empirical evidence this is beneficial?

Instructive thread by Alasdair explaining difference in covid vaccination policy in UK & EU vs US and the difference to flu vaccination. Refreshing to see nuance and the need for thinking in trade-offs which is a necessary element for building a sustainable and efficient public health policy.
You’ve missed the point

Not every seasonal vaccine requires an RCT (I don’t believe anyone is suggesting that currently)

The scenario for covid vaccines is unique as they were trialled on a background of ~zero population immunity

There is now substantial population immunity

The UK’s flagship health research programme promises breakthroughs, but beneath an NHS branded facade, critics are asking who really benefits from this vast database, heavily backed by industry and government.

This is a travesty & a nightmare. The US was a founder of @gavi.org. It lowers global vaccine costs, has vaccinated 1B children, & averted 19M deaths. This pull out will cost 100s of thousands of children's lives a year - and RFK Jr will be personally responsible.
