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.
