Lactoferrin is also able to kill SARS-CoV-2. In 2020 I had lactoferrin on fabric tested by a university laboratory for a potential product. The product didn't go anywhere after that, but it was conclusively shown that lactoferrin did inactivate the virus by about 92% instantly and 98% in a minute. If you want to use it as a mouthwash, the product Salivea (a quite pleasant product with a horrible name) has lactoferrin as one of the ingredients.
