BioBlock Nasal Spray

BioBlock® Nasal spray with antibodies against SARS-CoV-2 BioBlock® is a natural product derived from bovine colostrum that has been produced by cows, who had been hyperimmunized with the SARS-CoV-2 viral spike protein. Bovine colostrum is a milk produced by cows within the first few days after giving birth. It contains antibodies that provide passive immunity to the newborn calf. BioBlock® nasal spray is a natural product that contains antibodies against SARS-CoV-2 along with naturally occurring beneficial antibodies in colostrum which humans benefit daily while consuming dairy and meat products. In vitro testings demonstrated that the product blocks the entry of viral particles into cells. Tests were performed against initial Wuhan and newly mutated SARS-CoV-2 variants – Omicron (B.1.1.529), Indian (Delta B.1.617.2, Kappa B.1.617.1), UK B.1.1.7, South African B.1.351 and Brazil P.1. *BioBlock® is not a medicine. The product contains 150 spray doses.
