Inovio COVID-19 Vaccine Trials Put on Hold for FDA Questioning
Another pharmaceutical company has hit a speedbump in the race to come up with a coronavirus vaccine.
Inovio Pharmaceuticals says its phase two and three trials are on hold as it responds to additional questions from the FDA.
The bio-tech company says the pause is not due to any adverse reactions.
Inovio says once it responds, health officials have 30 days to decide whether its trial can continue.
