World Health Organization has said that there are no alternate medicines to cure COVID-19.
The University of Saskatchewan’s Vaccine and Infectious Disease Organization-International Vaccine Center (VIDO-InterVac) said that their vaccine has passed a significant milestone and has proven highly effective in ferrets. The University is undertaking critical research to find a vaccine to combat COVID-19 and have planned more trials in the coming months as they are moving towards human clinical trials. There is no mention of any discovery by a Chinese student.
Further, the WHO has said that there is currently no cure for COVID-19, and it may take 12-18 months before any vaccine is available.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
