5. One participant of Moderna's trial developed "a grade three fever, which is classified as 102.2 degrees Fahrenheit (39°C) or above, after receiving the lower vaccine dose", Reuters reported.

Antisera as a Covid-19 vaccine
The Indian Council for Medical Research, in association with a Hyderabad-based biopharmaceutical company, has developed "highly purified antisera" by injecting inactivated SARS-CoV2 into horses, which may be a potential treatment for COVID-19. Antisera are blood serum that is high in antibodies to specific antigens and are injected into humans to help reactivate the immune system to fight specific infections.
