Crying wolf like SAGE seem to do is very, very bad in the long term for science based reasoning.

Had booster booked fr tomorrow am but popped along to Whalley Range tennis club today & from asking if I could have walk in to getting jabbed must’ve taken less than 4 mins.
Remarkable.
I did a new gym class last weight (one of those Pump classes) & my arms were already fucked.
Wish me luck tomorrow!
Had a tight sweater on so had to strip in front of the woman administering the jab (she was gorgeous) & I was nowhere near beach ready.
Had to apologise.

Fake news, they’re more than 80% accurate.
On the flip side, friend of mine had symptoms, 3 positive LFTs so did a PCR. Came back negative. More positive LFTs, 2nd PCR was positive.

Could be a 2nd row in a ldies rugby team I suppose?
She’d most likely still be with us if she was double jabbed.

read the fine print.
“The figure for the Innova test used in the UK was 58%. The tests worked best in the first week after symptom onset.”
“people without symptoms the tests correctly identified an average of 58% of those who were infected. However, the number of samples from asymptomatic people was around 10 times lower than from symptomatic people in the studies analysed, limiting the conclusions that could be drawn, said the authors.”
Conclusion. Not all LFT’s are equal. The UK ones are at most 58%
Covid-19: Lateral flow tests are better at identifying people with symptoms, finds Cochrane review
Rapid antigen (lateral flow) tests are better at identifying covid-19 infection in people with symptoms than in those with none, although the diagnostic accuracy of different brands of tests varies widely, a Cochrane review has found.1 The review’s lead author criticised the UK government for...

And you.
Various studies have put the sensitivity of LFTs – in other words, their ability to detect the virus if it is there – at about 40 to 60 per cent. That sounds unhelpfully low, but it is an unfair measure as it compares LFTs to PCR tests, which are arguably too sensitive, says Irene Petersen at University College London. In the weeks following an infection, the cells of the nose and throat can retain fragments of virus genetic material that aren’t infectious, but that can be amplified by the PCR process, leading to a positive result.
Taking this into account, modelling work by Petersen’s team suggests that a study in Liverpool that gave a sensitivity of 40 per cent for LFTs actually indicates that their accuracy is more than 80 per cent.
