Hedt boerenbedrog van Bonte. Het is meestal beter om hem geheel te negeren, maar zo af en toe is het nodig om zijn vele missers weer eens te laten zien.
Steeds weer laat hij zien de details en concepten niet te snappen. En gedeeltelijk is dat expres, om angst aan te jagen.

It’s most dangerous to children and pregnant women. Before vaccination, measles was the leading cause of deafness, blindness, and intellectual disability in children, and a leading cause of miscarriage in women.

Every single unvaccinated person at the wedding also ended up contracting measles, and they fanned out far and wide,

We know that measles messes with the immune system, leaving those who are infected vulnerable to other viral and bacterial illnesses.

Behind my search for the source of the measles resurgence Nathan VanderKlippe’s journey to trace North America’s measles outbreaks sent him to New Brunswick, Texas and all the way to Thailand

Behind my search for the source of the measles resurgence

Not because she’s anti-vaccine. But because she thought childhood illnesses like measles were not a threat anymore.

Opinion: How a single measles case became 5,000 – and the lessons not learned It’s important not to lay blame, but to understand the virus’s epidemiology

How a single measles case became 5,000 – and the lessons not learned

A Canadian living in Thailand returned for a wedding. 5 days later he was hospitalized with pneumonia, a common side effect of measles. She was not vaccinated.

The CDC revives debunked 'link' between childhood vaccines and autism

The CDC's change is alarming PH experts. They are already worried about a drop in childhood vaccination, which has led to a resurgence of dangerous childhood diseases like measles and whooping cough.

The CDC pages have now been hijacked for state sponsored disinformation. It is terrible to see this happening. This is ideology, unscientific, over facts, data and the scientific method.

Some people do not fully recover from an acute viral infection and experience persistent symptoms or incomplete recovery for months or even years. This is not unique to the SARS-CoV-2 virus and history shows that post-viral conditions like post COVID-19 condition, referred to as LC, are not new

Children and schools were also affected by reduced cognitive performance after the flu.

It is nonsense. The same happened during the Flu pandemic. It is questionable if "intelligence" is assessed, or learning/concentration. This can be temperally altered due to a heavy disease such as an infection. But nothing more than that.

Then again, the same ACIP member things SARS-CoV-2 was a CIA operation. You just canΒ΄t make this stuff up. It is horrible and will cause much damage.

ACIP member Robert Malone pretends this was not the aim all along: to spread anti-vax and anti-science information from formarly reputable organisation.
It will cost lives, it will harm many, result in much heartache, but hey: MAHA.

Thereafter it is important to know that metabolites are important in many pathways and processes. That some are also involved in other diseases does not mean that disease is present or there is a risk to that disease.

That is all there is.

Also "complement and coagulation cascades, neutrophil extracellular trap (NET) formation, platelet activation, the estrogen signaling pathway, and thyroid hormone synthesis".

Many metabolites are involved in multiple pathways, and there is not much to conclude from them. Others are immune/inflammation related. Others show consequences of illness: reduced appetite and digestion.

Indeed, the authors found recently infected and hospitalised patients to have a different plasma content from not infected controls. They also found drug metabolites in the infection group, such as Tamoxifen, Olanzapine, and Ornidazole.

What would you expect? Lots of differences! After severe infection and recent duscharge there will be a lot of immune activity, much repair work and replenishing of depleted stocks of mediators. No infection control = no claims about SC2 specificity.

Non-infected controls (no infection controls) were vaccinated, ~200 days before sampling. No vaccine details about those infected, with several other differences, such as age, smoking, etc. The authors set themselves up for a fail. Yet, published in a metabolimics journal.

These are severe COVID-19 cases, and few subjects;: "Plasma samples from 29 hospitalized patients recovering from COVID-19 and 30 uninfected controls". In from December 2021 to January 2022. Important: timing. Very soon after hospital discharge.

Somewhat in 2020-2021, much less after 2022. But, PAIS, although rare, is possible after many an infection. The how remains a mystery.

Dan een warig verhaal over R-loops.Dan het niet begrijpen dat een qPCR cycle begint met 95C, die alles, DNA-DNA en DNA-RNA uitelkaar haalt. De onzin van deze mensen is bizar. Het hele stuk is een verzinsel van complot idioten.

Deze kunnen geen DNA aantonen in de aanwezigheid van zeer veel RNA.
Maar dit was echt lachen! Hij snapt echt helemaal niet wat Ct waarden zijn! Ct=de cycle waarbij het signaal over de vooraf gestelde drempelwaarde komt! Hij beschift de vermenigvuldiging! Vreselijk!

Hierna volgen de gebruikelijke leugens en onzin. Een gove leugen is dit. qPCR kan en detecteerd kleine stukjes DNA. Daarna wordt aangenomen dat dit stukje het hele plasmide voorsteld: de hoeveelheid wordt expres overschat!
Dan worden de foute methodes aangehaald.

Meer valse beweringen: cGAS-STING detecteerd alle DNA en RNA, van virussen, bacterieen, enz. Het wordt helemaal niet over-gestimuleerd. De cellen doen hun werk, breken het DNA en RNA af, en worden heel specifiek gedood.
