Summary

This is a proof-of-concept double-blind cluster randomized (1:1) parallel study. The randomization unit is healthy volunteers who have no symptoms of COVID-19 at the start of the study and have not been infected with the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) virus in the past 90 days. The selected individuals are randomly grouped in either the experimental group (individuals using the BioBlock® antiviral nasal spray immediately after waking up in the morning and thereafter once every 4 hours and so for 28 days) or the control group (placebo is used by individuals immediately after waking up in the morning and thereafter once every 4 hours and so for 28 days).

Conditions

  • SARS CoV 2 Infection

Interventions

BIOLOGICAL

BioBlock® antiviral nasal spray

SARS-CoV-2 BioBlock is a natural preparation derived from bovine colostrum, where animals have an immune response against the SARS-CoV-2 spike protein in addition to conventional vaccines. The antiviral colostrum preparation was made from colostrum of cows immunized with SARS CoV-2 spike protein. Pregnant cows were immunized during the third trimester of gestation using a non-infectious recombinantly produced and purified SARS CoV-2 spike protein. Colostrum, which is milked after calving, concentrates most of the antibodies produced in the cow's body at very high concentrations, including neutralizing antibodies to SARS CoV-2 produced as a result of immunization.
