Whey protein from human breastmilk inhibits SARS-CoV-2 infection

Many scientists have reported the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on pregnancy and the virus has been detected in breastmilk. Now a new study published on the preprint server bioRxiv* in August 2020 shows that whey protein in human breastmilk efficiently prevents infection with SARS-CoV-2 as well as post-entry viral replication.

Milk contains an abundance of useful components such as proteins, minerals, vitamins, and antimicrobial compounds. It antagonizes the activity of viruses like hepatitis C virus (HCV), human cytomegalovirus (HCMV) and human immunodeficiency virus (HIV). Milk lactoferrin inhibits the intracellular replication of HCV.

The current study aimed to examine the activity of whey protein in human breastmilk against SARS-CoV-2 and the pangolin coronavirus GX_P2V, which is closely related to it.

The researchers found that Vero cells infected with pseudovirus expressing SARS-CoV-2 antigens in the presence of breastmilk, all the milk samples from different donors efficiently inhibited over 98% of infection, in both the original condition and at serial two-fold dilutions....

When repeated with the pangolin CoV, inhibition occurred to almost 100%, and dose-dependent inhibition was observed following two-fold serial dilutions. The EC50 ranged between donors, from 0.34 mg/mL to 0.79 mg/mL, while the milk promoted cell proliferation.

The researchers also found that at varying concentrations from 0.16 mg/mL to 4 mg/mL, human breastmilk showed a dose-dependent inhibition of viral infection. When the supernatant was used to infect other cells, plaque assays showed that all control dishes were positive for the live virus, and the titer went down with dilution of supernatant. However, when treated with 4 mg breastmilk, no live virus was found in any dish. At 0.16 mg/mL, live virus was detected below a supernatant dilution of 1: 1,000 and even below 1: 10,000. Thus, human breastmilk inhibits infectious particle production.

If I were on a trial for this, I would ask the doc to sign me up for the highest possible dose that would take the longest to deliver.

We’ll know the economy is in the toilet when we see mothers hawking expressed breast milk on street corners.

A superb motion picture. Cinema as an art form.

I've seen rumors on the internet that somewhere there is a silent version in black and white.

Wish I could find it.

"We’ll know the economy is in the toilet when we see mothers hawking expressed breast milk on street corners."


That's for sure!   (And, like other things sold on street corners, not all breast milk is equal or safe, and, if my understanding is correct, some breast milk can actually "pass on strains of pathogens known to cause other diseases in humans".)

Your post also triggered another thought in me.   When I was a little kid, we'd sometimes go to a professional baseball game (back when that was still a good thing to do), and there would be guys walking through the crowd, yelling, "Cold beer here!"   Can you imagine what those poor mothers might be yelling, when hawking their expressed milk?   I can think of a couple possibilities at least (which I won't specify here).        :-)
