The purpose of BioShield is to provide widespread protection against the novel coronavirus SARS-CoV-2 (COVID-19), enabling the world to re-open and stop the damage to the global economy.


The coronavirus SARS-CoV-2 (COVID-19) is now a worldwide pandemic, overwhelming health care systems globally and creating profound economic and human distress and damage. In addition, risks of food insecurity in developing economies are growing rapidly. Meaningful interventions are urgently required to enable society and commerce to begin to re-open and approximate to the pre-pandemic norm. 

Vaccines are key to the long-term solution, but may take one to two years to be developed and may not work for all groups, such as the elderly. In the interim, an important tool for the prevention and control of infectious pandemics is passive immunity.

The Breakthrough Solution

Polyclonal anti-SARS-Cov-2 IgY

The Bridge Institute, working with leading scientists, has progressed a passive immunity solution called Polyclonal anti-SARS-CoV-2 IgY.  Specific pathogen-free chickens are immunized with inactivated SARS-CoV-2 coronavirus and their eggs are harvested. Polyclonal yolk immunoglobulin (IgY) is extracted from the yolks using a water dilution method, followed by further purification.  Clinical studies have demonstrated that polyclonal IgY antibodies with high purity can neutralise viruses with efficacy and safety.

After refinement, the product can be administered orally and/or intranasally, twice daily. The polyclonal IgY binds to and neutralizes SARS-CoV-2 virus in the nasopharynx and gastrointestinal tracts, offering immediate protection. This product will rapidly clear the virus from the nasal passages and gastrointestinal tract, thus rendering the infected persons “virus free’. This then stops virus spread, decreasing the transmission factor to very low levels.

 It can be cost-effectively scaled globally by October 2020. It is a bridging solution, which offers immediate short term protection for individuals, until a global vaccine is developed. 

A global passive immunity with Polyclonal anti-SARS-CoV-2 IgY

The Benefits

It is rapidly scalable

Vaccination of chickens and automated collection and processing of eggs is already carried out on an industrial scale – 30m doses a day could be made in one farm.

It is inexpensive

Estimated cost of each dose is between (US) 3 cents and 12 cents.

It is safe

IgY has been proven to be safe for humans and does not create an inflammatory response. It is natural and does not involve humans being exposed to the virus.

It is suitable for all

Including compromised patients with comorbidities and the elderly.

The protection is immediate

Consumption twice a day will provide the required protection.

It will not burden the health system

A self-administered treatment, either intranasal or oral.

The Stages of Development


The program comprises of two key stages: (1) Proof of Concept and Regulatory Interactions and (2) Human Studies, Scale up and Manufacturing.

Stage One

Proof of Concept and Regulatory Interactions

The proof of concept includes immunization, egg collection, IgY titer determination and neutralization studies. Regulatory interactions will include submission of a pre-IND (Investigational New Drug) request to the US Food and Drug Administration (FDA) to align on the proposed development program. We will also ensure that other national agencies receive regulatory applications to allow the usage of the product worldwide.
Stage Two

Human Studies, Scale-up and Manufacturing

This stage includes the clinical development program as agreed with regulators (e.g. the FDA), and the national / international planning and preparation for scale-up. Manufacturing feasibility has been established for inoculant preparation, flock immunization, egg collection, breaking, separating and drying. Large scale IgY extraction and lyophilization facilities are commercially available, enabling rapid production at volume.
