Chicken Egg Yolk Antibodies (IgYs) block the binding of multiple SARS-CoV-2 spike protein variants to human ACE2

Shuangshi Wei et al. Int Immunopharmacol. 2021 Jan.

Abstract

The SARS-CoV-2 virus is still spreading worldwide, and there is an urgent need to effectively prevent and control this pandemic. This study evaluated the potential efficacy of Egg Yolk Antibodies (IgY) as a neutralizing agent against the SARS-CoV-2. We investigated the neutralizing effect of anti-spike-S1 IgYs on the SARS-CoV-2 pseudovirus, as well as its inhibitory effect on the binding of the coronavirus spike protein mutants to human ACE2. Our results show that the anti-Spike-S1 IgYs showed significant neutralizing potency against SARS-CoV-2 pseudovirus, various spike protein mutants, and even SARS-CoV in vitro. It might be a feasible tool for the prevention and control of ongoing COVID-19.

I have noticed that my birds are not laying like they once did, but mine are atleast 3 years old and for awhile, i assumed that it was because my roosters outnumbered my hens. My eggs used to be bigger than the store bought but now they are smaller. also, my birds eat some of the eggs, which would normally indicate a vitamin problem, but even with supplementation, this still happens from time to time.

i do believe that they are messing with the feed, and i do believe that there is power in the egg. its ok though, all they are doing is pushing people closer to the light so that we live as God intended.

Could be. Does your chickens get enough calcium and sunlight?

sorry for the late reply. yes, my chickens spend most of the day out in their large pen. on top of their normal laying pellets, they also receive oyster shell supplements.
