Prof Adam Finn on Radio 4’s Today programme (@BBCr4today):

“We’re in a very different place with almost everyone in the population immune to SARS-CoV-2...”

This statement is incredibly poor public health messaging. Here’s a quick thread of reasons why…

🧵
If we’re all so ‘immune’, why is it that, as recently as mid-December 2023, 1 in every 24 people across the whole of England were infected with Covid?

If we’re all so ‘immune’, surely such high waves of Covid shouldn’t be happening repeatedly?

If we’re all so ‘immune’, why do the scientific studies show that people infected with the Omicron variant (& its many sub-variants) have very little natural immunity boost against future Covid infections?

imperial.ac.uk/news/237315/om…
Image
If we’re all so ‘immune’, why does very recent research on the currently circulating JN.1 Covid variant show that protection against reinfection rapidly declines to just 50% after 6-9 months & is down to negligible levels after one year?



(H/t @ejustin46) medrxiv.org/content/10.110…
Image
If we’re all so ‘immune’, why have there been nearly 4.5 THOUSAND registered Covid deaths just in the first 17 weeks of 2024?
Image
If we’re all so ‘immune’, why is Yale School of Public Health telling us that growing research shows that Covid infections can have a lasting detrimental effect on people’s immune systems, making them more susceptible to other opportunistic infections?
Image
The really concerning thing is that Prof Adam Finn is a key member of the JCVI, the committee which decides who does and doesn’t get offered a Covid vaccine… Image
Prof Finn has stated in the past (before the Autumn booster):

“There's no real value in investing a lot of time & effort immunising them again.”

He’s made it clear that the UK’s strategy is a ‘get infected to protect against getting infected’ strategy.

bbc.co.uk/news/health-66…
Image
Let me translate:

The stated aim is to get infected over & over & over again… to protect against getting infected over & over & over again!

How does this make any sense at all when there are vaccines available? Image
It also seems to be a direct contradiction of what Prof Chris Whitty said recently (in November 2023) at the Covid Inquiry:

“The ONE situation… that you would ever aim to achieve herd immunity is BY VACCINATION. That is the ONLY situation that is a rational policy response.”
Worse still, it turns out that the government would rather throw away the vaccines they’ve ALREADY BOUGHT (with taxpayers money), rather than using them to protect people…

…and so millions of doses have tragically been destroyed.

You can read more about that in this thread ⬇️
For the Spring 2024 booster campaign, the *same* cost-effectiveness methodology was used, with the same fundamental flaws.

Aspects ignored in analysis include:
▪️Long Covid in non-hospitalised patients
▪️Primary care costs
▪️Infection control in hospitals
▪️Workplace absences Image
One of the key aspects that has been left out of the cost-effectiveness analysis is the impact of Long Covid in NON-hospitalised patients…

…despite studies which tell us that Long Covid strikes after MILD initial symptoms in ~90% of cases.

fortune.com/2023/01/05/ori…
Image
We also know that Covid vaccination dramatically lowers the risk of Long Covid.

“A meta-analysis of 24 studies found that people who had received 3 doses of Covid vax were 68.7% less likely to develop Long Covid compared with those who were unvaxxed.”

scientificamerican.com/article/vaccin…
Image
Meanwhile, 2 MILLION people are now suffering from Long Covid across England & Scotland.

That’s a massive 3.3% of the entire population.

Over 380,000 people reported that their daily activities were SEVERELY impacted by their Long Covid illness.

ons.gov.uk/peoplepopulati…
Image
30% of these people currently affected by Long Covid have been suffering for under a year.

It’s clear that this is NOT just a legacy problem from the early waves of the pandemic.

With each new wave of Covid infections, more & more people are succumbing to Long Covid… Image
Multiple studies show that the risk of Long Covid increases with each subsequent infection.

This study from @StatCan_eng showed that the risk of developing Long Covid is:

▪️15% after 1 infection

▪️25% after 2 infections

▪️38% after 3+ infections - that’s 1 in 2.6 people!
Image
And this study from Prof. Al-Aly (@zalaly) also clearly demonstrated that the risk of developing Long Covid symptoms increases with each successive reinfection.

Just because you’ve had Covid before & were fine, it doesn’t mean you’ll be fine next time…

nature.com/articles/s4159…
Image
With no mitigations to reduce the spread of Covid, we keep getting infected again & again.

But reinfections are NOT harmless.

Each infection is a game of Covid Roulette as to whether you’ll end up with long-term health repercussions.

time.com/6553340/covid-…
Image
Many people may think they’ve fully recovered from their Covid infection…

…but this is a virus which causes untold damage below the surface…

…and the full impact of the longer term ‘silent’ organ damage may not become apparent for several years.

rsm.ac.uk/media-releases…
Image
A recent study found that people who caught Covid were 5x more likely to die from heart disease in the 18 months after infection.

As of June 2023, there had been nearly 100,000 more deaths than usual attributed to heart problems since the pandemic began.

bhf.org.uk/what-we-do/new…
Image
One of the aspects I’m most concerned about is the long-term damage which Covid can cause to the brain.

We now know that Covid infection can lead to a plethora of new neurological symptoms, including confusion, difficulty concentrating, memory problems, depression & anxiety.
All this is leading to a BIG problem…

As Prof Danny Altmann (@Daltmann10) wrote in this paper:

“The oncoming burden of long COVID faced by patients, health-care providers, governments and economies is so large as to be unfathomable…”

nature.com/articles/s4157…
Image
Cambridge Econometrics have done some important analysis into the economic burden of Long Covid in the UK through to 2030…

If prevalence of Long Covid increases to 4 million people by 2030, this would lead to:
▪️a reduction of 2.7 BILLION in GDP
▪️311k job losses PER YEAR.
Image
To anyone paying attention, none of this should come as a surprise...

When you mass infect a population with a disease which, according to the World Health Organisation, causes long-term chronic illness in around 10% of infections, then this is the inevitable consequence.
Experts have predicted for several years that Long Covid would lead to a tsunami of disability.

Our government ignored those warnings and now we must all face the consequences...

It’s time to stop brushing Covid and Long Covid under the carpet.

It doesn’t have to be this way.

We could be doing SO much more to reduce the spread of infections and halt the gradual decline in the health of our nation & economy.

FROM THE OLYMPICS TO NASA, WEARING MASKS IS BACK - EXCEPT IN HEALTHCARE

Brilliant article on how masking is increasingly popular with Olympic athletes, actors & astronauts wanting to avoid illness…

…but sadly, in hospitals, masking is rare & those who do are often gaslit.

🏴󠁧󠁢󠁳󠁣󠁴󠁿 Something unusual & concerning in Scotland’s Covid data in the last few weeks.

There’s been a sharp rise in the proportion of hospitalised Covid cases which are children.

Currently over half of all Covid hospitalisations in Scotland are kids aged 0-14 years.

(h/t @gwladwr) Image
The data also shows that, since January, Covid incidence rates for these younger age groups have been going into the ‘high’ (dark blue) and ‘very high’ (purple) classifications, particularly the 1-4 years age group. Image
I’ve also taken a look at the England data and Covid positivity rates have been rising sharply in recent weeks in the 0-14 age groups.

Definitely one to watch in the coming weeks… Image

🏴󠁧󠁢󠁥󠁮󠁧󠁿PUPIL ABSENCE - AUTUMN 2025

The DfE have now published pupil absence data for the Autumn term:

🔎 Pupil illness absence across the autumn term averaged out at 3.44% (compared to pre-pandemic average of 2.5%).

🔎 By the end of Nov, illness absence had soared to 4.7%.

🧵 Image
DfE commentary:

“The increases seen in the latter weeks of term were mainly driven by illness-related absence”

“This increase in absence is equivalent to approximately 500,000 less days in school compared to the previous autumn term.”

…e-education-statistics.service.gov.uk/find-statistic…Image
To anyone paying attention, these illness absence figures should not come as a surprise.

By early December, UKHSA was warning about how flu was spreading like wildfire through classrooms, leading to very high infection rates in school-age children (pink & green lines on chart). Image

COVID & CHILD DEVELOPMENT

New US study showing impact on child brain development when their mothers are infected with COVID during pregnancy.

Results show:
🔎 Structural differences in regions of the brain
🔎Lower cognition & social-emotional scores

sciencedirect.com/science/articl… x.com/harryspoelstra…Image
And here’s another study, this time from Brazil (published Jun 2025), which also shows the impact of maternal COVID infection on child development.

At 24 months:
🔎 36% of infants exhibited cognitive delays
🔎 64% communication delays
🔎 57% motor delays

nature.com/articles/s4139…Image
And another study, just published this week (Jan 2026) in ‘Obstetrics & Gynecology’, came to similar conclusions…

“Maternal SARS-CoV-2 infection in pregnancy was associated with increased risk of adverse neurodevelopmental diagnoses by age 3 years”.

“When it comes to flu, the focus is often on droplet transmission, but there’s also evidence of aerosol transmission. That means that ventilation & air filtration are HUGELY important.

“Are the Govt looking to improve that to help deal with all the respiratory infections?”

This feels like an important breakthrough moment…

On the BBC News this evening, Medical Editor @BBCFergusWalsh clearly stated:

“As for facemasks, simple surgical masks are *not* good at stopping viruses. You really need a properly fitted tight respirator mask for that”…

/1
…which begs the question, why does the NHS infection control guidance STILL only recommend surgical masks for treating patients with airborne viruses like flu & Covid… and not proper FFP3 masks?

Even Baroness Hallett was rather perplexed by this during the Covid Inquiry.

/2
The IPC experts (Dr Warne & Dr Shin) who provided independent specialist advice to the Covid Inquiry both stated that IPC guidelines should be updated to recommend routine use of FFP3 masks when caring for patients with ANY respiratory virus.

So why has this not been done?
