AstraZeneca puts leading COVID-19 vaccine trial on hold over safety concern
The final clinical trials of a coronavirus vaccine developed by AstraZeneca and Oxford University have been put on hold over safety concerns. According to the information, a participant had an adverse reaction in the UK.
AstraZeneca has called it a "routine" pause in the case of "an unexplained illness". The world is keeping a close eye on the outcome of vaccine trials. AstraZeneca-Oxford University vaccine is one of the strong contenders among dozens of vaccines being developed across the globe.
The hopes with the AstraZeneca-Oxford University vaccine are high as it could be one of the first to come in the market, the BBC reported. The vaccine candidate had shown positive results in phase 1 and 2 testings.
Phase 3 has involved around 30,000 participants in the US as well as in the UK, Brazil, and South Africa. The Phase 3 trials in vaccines involve thousands of participants and can last several years.
An Oxford University spokesperson was quoted by BBC as saying: "In large trials, illnesses will happen by chance but must be independently reviewed to check this carefully."
