It's been a week since AstraZeneca reported adverse reactions during COVID-19 vaccine trial... and Pfizer also reported mild-to-moderate side effects from the vaccine it is trialing.
According to Pfizer's executives, over twelve-thousand participants have received a second dose.
Over 29,000 volunteers have already been chosen, and the goal is to have 44,000.
While the company is closely analyzing the safety and tolerability of the vaccine during the study, an independent data monitoring committee could recommend a pause at any time.
While AstraZeneca's resumed its trials on Monday, the news still affected people worldwide.
Some of Johnson and Johnson's volunteers, worried about the side effects, have quit.
However, the company claimed the situation is under control.
"Still, it hasn't affected us much, because the number of volunteers, particularly in the 18 to 55 age-group, have left us with enough reserve volunteers."
The firm's Belgian unit began its Phase II of trials in Spain this week.
The company aims to test 60-thousand people globally in Phase Three and include people from all walks of life.
In the meantime, China could have a vaccine ready for the public as early as November according to an official with the Chinese Center for Disease Control and Prevention.
She said the current Phase 3 of the clinical trials were proceeding smoothly and three of the country's vaccines have already been offered to essential workers under an emergency use program launched in July.
