Thai university reports positive results in COVID-19 vaccine animal trial

BANGKOK (Xinhua) – A Thai university yesterday published on its website the positive results in animal trial for a COVID-19 candidate vaccine.

Chulalongkorn University said that its joint research with BaiyaPhytopharm, a startup Thai pharmaceutical firm, has shown encouraging results in boosting antibody levels in hamsters, rats and monkeys.

“We used Baiya SARS-CoVVax 1, which was developed from nicotianaben-thamiana tobacco leaves, and tested on white mice and monkeys,” said Dr Suthira Taychakhoonavudh, a researcher involved in the development of several COVID-19 candidate vaccines.

Dr Suthira said that the test results from the animals showed that the vaccine boosts the level of antibodies in their bodies effectively after two doses.

“Our next step will be to evaluate the toxicology or side effects of the candidate vaccine,” said Dr Suthira, who is also associate dean of the Faculty of Pharmaceutical Sciences at Chulalongkorn University.

Dr Suthira said the COVID-19 immunity level of the monkeys in the tests will be reviewed again six months after they were initially vaccinated.

Meanwhile, Chulalongkorn University Vice Rector Dr Narin Hiransuthikul said that the university is in close consultation with the National Vaccines Institute, the Food and Drugs Administration and the Faculty of Pharmaceutical Sciences, to seek endorsement as well as to ensure that the candidate vaccines meet the required international standards.
