WHO(World Health Organization) told Corona virus patients should take two doses of Pfizer/BioNTech vaccine within 21-28 days.
“We deliberated and came out with the following recommendation: two 2 doses of this vaccine within 21-28 days,” says Alejandro Cravioto, the chairman of WHO’s Strategic Advisory Group of Experts on Immunization (SAGE).
“SAGE did not recommend the Pfizer jab for travellers unless they were in a very high-risk group due to the very limited supply of anti-COVID drugs at present.”, told Alejandro.
“While we acknowledge the absence of data on safety and efficacy after one dose beyond the three-four weeks studied in the clinical trials, SAGE made a provision for countries in exceptional circumstances of (Pfizer) vaccine supply constraints to delay the administration of the second dose for a few weeks to maximise the number of individuals benefiting from a first dose,” Alejandro added.
He also told: “I think we have to be a bit open to these types of decisions which countries have to make according to their epidemiological situations.”
A WHO immunization expert, Kate O’Brien, said “there was no outside limit for receiving a second vaccine dose. Alluding to delays in rolling out inoculations”, she said: “Nobody expected this to be easy and we are starting to see where the road bumps are and where we need to make adjustments.”
Maria Van Kerkhove, The technical chief of WHO, told that “there is no indication that the coronavirus variant identified in South Africa is more transmissible than the one spreading fast in Britain.”
WHO director general, Tedros Adhanom Ghebreyesus, told “very disappointed” that China had not authorised entry of an international mission to examine the origins of the global coronavirus pandemic.”
“Today, we learned that Chinese officials have not yet finalised the necessary permissions for the team’s arrival in China,” Tedros said. “I have been in contact with senior Chinese officials and I have once again made it clear the mission is a priority for the WHO.”
On 31st Dec,2019 China reported cases of pneumonia in the city of Wuhan and from there the CoVID-19 virus started.
