Gum laced with a plant-grown protein is found to reduce COVID-19 transmission by 95% after trapping and neutralizing the virus in the person’s saliva, Penn State University scientists find

New type of gum has been found to nearly eliminate transmission of the coronavirus by neutralizing the virus in the person’s saliva.

A team of scientists led by Penn State University infused gum with a plant-grown protein and found it ‘traps’ the SARS-CoV-2 virus.

The protein, known as ACE2, prevents the virus from attaching to a host cell in the human body by interacting with SARS-CoV-2’s receptor binding domain – this facilitates virus attachment to the receptor and fusion with cell membrane.
