Meanwhile, the World Health Organisation (WHO) has maintained that developing a vaccine for Coronavirus may take a year or more.

In a separate development, the Indian Council of Medical Research has said that it won’t yet recommend the use of BCG vaccine in fighting COVID-19. A study will begin next week on this subject, ICMR head scientist Dr Raman Gangakhedkar told news agency ANI. “Till we don’t have definitive results from this, we won’t recommend it even for health workers,” he said.

The WHO, too, has not endorsed claims the BCG vaccine can be used for the prevention of COVID-19.
