when it comes to viruses, not much difference in time compared to bigger organisms. virus evolution (SARS1 to SARS2) it's just a matter of 10 years. Virus mutations (Wuhan1 to Wuhan2) a few weeks, to our recent variant a few months.

you seem to deny the fact that our body don't have better weapons against covid now than our ancestors against the 1918 flu. Our own biological evolution is nowhere as fast as that of the corona viruses.

we live better but we still face the virus with our immune system in the same way.

compared to the 1918 flu, 228,000 deaths out of 43 millions UK residents. Back then, the population density was a third less, so herd immunity could be achieved with smaller percentage - say 60%. The fatality rate would be around 228,000/26 millions, a tad under 0.9%. On this progression, the...

the 1.25% comes from 100,000 deaths/8 million cases, estimate by ONS, taking into account those who don't bother with a test. If you go for herd immunity without vaccines, you multiply these two numbers by 8.

but your strategy is similar to what the government has been doing. We still have no effective treatment, only stuff to relieve symptoms. The only way out is still the vaccines which is herd immunity without catching the disease. The basic case fatality rate 1.25% still holds true.

there may be a simpler explanation. Degrees are easier to earn. We have also stopped making things so there are fewer opportunities to learn on the job.

ONS: https://www.ons.gov.uk/peoplepopulationandcommunity/healthandsocialcare/conditionsanddiseases/articles/coronaviruscovid19infectionsinthecommunityinengland/antibodydatafortheukjanuary2021 According to the ONS, around 8 millions of us have been infected at some time in the past year. 3.54...

there are traces. those who came into contact with Covid produce antibodies. The 15%-18% is ONS estimate based on their survey of covid antibodies. I watched Robert Cuffe on BBC last Tuesday.

yes, a bit. there are 5 millions that have been vaccinated with the first jab. The rate of vaccination at present is 2 millions a week, and increasing. If you split half way, you can carry on giving 1 million jabs a week to the first group their second dose at 3-6 weeks, continue with the...

Hello Bob, we have new arrival at the end of March.

we would have been up the present creek back last spring. Even now, around 15% of us have come into contact with the virus and our hospitals are already overflowing. Just imagine what they would be like if 7 millions of us down with covid and need hospitalisation in 3-4 months. The case fatality...

from what he said (I watched him on BBC News), some residents died after being vaccinated with the first jab. His point is the vaccine does not work on more than half, they (the latter group) get virtually no protection. Basically, the outcome is not uniform. Some are just unlucky.

He made the point that some care home residents are unlucky enough to belong to the group where the vaccine doesn't work. That group is worryingly large after only 1 jab, as much as 75%. Can you put a value to the first vaccine jab for a care home resident? then treble it for the second jab...

like the covid loans to businesses. Our government got scammed for tens of billions.

New Covid variants may pose problems for vaccines quote: The study was posted on the website for KRISP, the Kwazulu-Natal Research Innnovation and Sequencing Platform. The other two studies were posted on a pre-print server. In the study that had similar findings, blood was drawn from 44...

the angle of the spoke entering the hole in the rim is such that the nipple usually is stuck solid in the hole. When you go over a pothole, your loosened spoke will go into compression. This situation happens far more often with thicker e-bike spokes, 13 gauge instead of 14.

I was catching up with nuclear fusion progress, now that all the planet's richest people put their money in fusion tech startups Bezos, Gates, Musk etc all did. I came across an interesting comment by Kolemen, a big name in the business: Koreans, Japanese and Chinese are also catching up. It...

14 gauge (1.9mm diameter): 740 lbs, 336kgf to break it in the middle. But spokes never break in the middle. They either break at the J bend or at the end of the thread. Spokes work in extension (tensile) and usually break in compression, that's their weakness. If your spokes are loosened, you'll...
