COVID-19: Men create more antibodies after asymptomatic infections and keep them longer
MedicalXpress (UK) ^ | April 7, 2021

As COVID-19 has swept across the globe, it seems that high transmission rates have partly been driven by a large number of people catching the virus, not experiencing symptoms and then unknowingly passing it on.

(excerpt)We know that the production of protective antibodies following an infection forms the basis of immunity. But while it's clear that infection with the coronavirus results in antibody production, we aren't sure of the amounts of antibodies produced, how long they last, or whether they protect people from getting COVID-19 again.

(excerpt) To run our screening program, we used a lateral flow "pregnancy-like" test strip that provided a result from a single drop of blood within ten minutes. These results were then compared to two independent "gold standard" methods used by public health laboratories to test for COVID-19 antibodies. Our study looked at the same people at two time points, three months apart.

(excerpt) At the time of their first test in July 2020, all participants were well, hadn't previously received a COVID-19 diagnosis and didn't have any obvious symptoms of disease, though some reported having experienced mild COVID-related symptoms in the three months beforehand.

(excerpt)

Our study didn't find a statistically significant difference in the number of men and women who had antibodies, although antibody prevalence was highest in men over the age of 40. However, when we compared antibody levels in those who tested positive, we did find a key difference: male participants' levels were three times those of female participants. This was despite there being no difference in the previous COVID-related symptoms reported by men and women—suggesting no difference in the severity of the infections that produced them.

When we followed up with a second test three months later, we found another key difference. Of those who had previously had antibodies against COVID-19, 21.7% no longer tested positive, implying that one in five asymptomatic people who generate antibodies against COVID-19 lose these after six months (as the likely time of infection for those testing positive in July was roughly three months' prior to this, at the height of the first wave).

Interestingly, 80% of those who had lost their antibodies in our study were women. The women who had lost their antibodies were also on average ten years older than women who retained antibodies. This may be related to an altered immune response in women who are approaching the menopause or are post-menopausal, similar to that seen in the flu.

From the article: “As COVID-19 has swept across the globe, it seems that high transmission rates have partly been driven by a large number of people catching the virus, not experiencing symptoms and then unknowingly passing it on.”

Asymptomatic Spread of Coronavirus is ‘Very Rare,’ WHO Says

https://eyewire.news/articles/asymptomatic-spread-of-coronavirus-is-very-rare-who-says/

“From the data we have, it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual,” Dr. Maria Van Kerkhove, head of WHO’s emerging diseases and zoonosis unit, said at a news briefing from the United Nations agency’s Geneva headquarters. “It’s very rare.”

This whole asymptomatic spread has been promulgated as an excuse to require everyone to wear a mask. It also is part of the ‘in an overabundance of caution’ strategy of NIH and CDC.

Essentially, NIH panicked believing COVID was Spanish Flu 2.0. The virologists have been dreaming of another spanish flu to demonstrate their abilities to contain a Pandemic. This was to be their big chance. They blew it like the little boy crying wolf.

Actually they were hoping it would be Spanish Flu 2.0

That's why they took out all the patents on coronavirus vaccines way before any outbreak.

Yes, with their plan to depopulate the Earth, they were hoping and planning that their little scheme would be as deadly as the one in 1918.

Turns out it was a dud (if you understand the number of deaths they really wanted), so they got the media and medical establishments on board to gin it up into something that was no more deadly than a bad flu.

They hoped that by using the regular cold and flu season they'd get a running start and with a heavy dose of political awareness and fear porn they would be off to the races.

Feminists everywhere are outraged, and demand equal antibody protection. Congress to pass a law requiring equal protection, regardless of which of the 9000 ge ders one claims to be

So, who is right, the W.H.O.,

“Asymptomatic spread is very rare”:

Interesting. I know women don’t suffer quite as badly from COVID overall, so I’m guessing that their T-cell response is stronger, negating the need for as many antibodies.

Otherwise, immune systems are sexist. Just wait until MLB and Woke-A Cola hear about this!

Sounds sexist misogynistic to me.
Men must be prevented from creating and retaining more antibodies.

True. It seems Nature's God has provided men superior strength and women with superior health.

It goes back to original (God's) gender roles for many mammals.

but that is racist, sexist and something else to even acknowledge men in anything other than evil
