These first generation vaccinations are not the Get-Out-Of-Pandemic Card some dream of
What a can of nematodes

Public Health England say viral loads appear similar among people infected with the Delta variant in both groups, meaning, theoretically, they are equally contagious.
But health chiefs insisted the current crop of vaccines still cut the risk of catching the virus in the first place.
Vaccinated people may be less likely to catch Covid (at least for a few months until it wears off) but when vaccinated people do get infected the viral loads are pretty much the same as when unvaccinated people do. In other words, fully vaccinated people can still be dangerous to the people around them. And if they fly in without quarantine, they can bring outbreaks and new mutants too. So much for the freedom jabs. Though, in fairness, at the moment, they still offer some freedom from hospital, just not freedom from masks, quarantines, and restrictions.
Vaccination clearly isn’t going to stop the spread, eliminate the virus, or do a lot to protect your loved ones or work colleagues. It makes it hard for companies to justify mandatory vaccination “for the greater good”. The question, “Would you sit next to an unvaccinated person” isn’t quite the loaded probe it was. And you can always reply: “Would you work with someone who was Vitamin D Deficient“? I mean really, they are defenceless.
When will companies set up mass Vitamin D testing and free supplements?
A couple of weeks ago the Israeli data suggested only 16% of people were still protected from infection six months after vaccination. Presumably Governments will argue that vaccines still reduce the burden on the health care system but new mutations may render that moot too.
The lines that matter in the graph below are the three in the bottom right. That’s the viral loads of the vaccinated, and unvaccinated, with Delta variant. The lines trailing up on the right are probably the last vestiges of the old alpha (UK) variant which only exists anymore in long recovering patients with low viral loads.
Being low on this graph is bad. The lower the Ct value, the higher the viral load. When there is hardly any virus (or fragments thereof) it takes a lot more cycles to detect and so has a higher Ct value.
NHS Test and Trace data – published in the PHE report – showed daily average Ct values for unvaccinated people who caught the Delta strain was 17.8.
Meanwhile, it was only slightly higher for fully-vaccinated Brits (18).
There are qualifiers, but it is an act of some optimism: We don’t know if the ages of both groups were the same, and if the vaccinated group were older they might have lower viral loads than unvaccinated people their own age. We need to follow both groups through their infections as they progress to know what the real peak is. These groups may have got tested as different points on the curve.
But the figures are similar to the US findings and the US CDC said “wear your masks” to the vaccinated:
The report follows similar findings by the CDC, which last week released figures showing unvaccinated and double-jabbed Americans had very similar viral loads.
The research led them to U-turn on mask advice and recommend fully- vaccinated Americans wear coverings indoors again.
The PCR test picks up fragments of the virus, not whole virus, and viable virions are usually much lower in number but that probably applies to both groups equally.
Delta Variant is the Indian variant. The Alpha variant is the UK strain.
