Jeremy Sullivan, investment adviser with Hamilton Hindin Green, said investors may have got ahead of themselves and there's still plenty of water to go under the bridge in developing the vaccine.
"The vaccine needs to be peer reviewed and it needs US Food and Drug Administration approval. The milestone will be in two months time when they report back on any side effects involving the vaccine.
"Later in the day, the Chinese said their vaccine had caused adverse reaction with some of the 60,000 people tested and their trial has been halted. The market then started giving back all its gains," Sullivan said.
