A pig vaccine for COVID-19 is being researched

"As previously reported a virus expert working at the John Innes Centre in Norwich is working on creating a vaccine against coronavirus in pigs - which if it works, could possibly be used on humans. Professor George Lomonossoff, who is an expert in viruses having worked for 40 years at the John Innes Centre, began his work studying plants. But for the past few months he has been experimenting on a vaccine to prevent coronavirus in pigs. If it works - and produces antibodies that create an immunity against the virus - he thinks it could be developed for possible use in humans against Covid-19."
