According to a report by a foreign news agency, an online news briefing by the WHO said that there was no data on the results of use of the vaccine three to four weeks after the second dose.
The head of the World Health Organization, Dr. Tedros, criticized China, saying that so far China has not allowed all members of the global mission to enter the country to find out the origin of the Corona outbreak.
Dr. Tedros said he reiterated that knowing about the origin of the virus was one of the WHO’s priorities.
It is to be noted that the head of the emergency department of the World Health Organization, Michael Ryan, had said during a press briefing on December 28 that the epidemic of corona virus is a call to wake up from a dream of negligence.
It may be recalled that this briefing was given by the World Health Organization on the one year anniversary of the spread of Corona virus. The Corona virus has killed nearly 1.8 million people worldwide in one year, with more than 80 million confirmed cases.
