World Health Organization listed AstraZeneca - Oxford University's COVID-19 vaccine for emergency use

Speaking at press briefing in Abuja, the Director General of NAFDAC, Professor Mojisola Adeyeye, said the agency got the dossier of the vaccine a week ago, while its safety committee went to work immediately to evaluate its safety and efficacy for Nigerians.

Dr Sultan said that while the process of vaccination could not be started in 110 countries, Pakistan was among those 65 countries where vaccination has begun.

Sultan said that COVAX would provide 2.8 million doses of Oxford AstraZeneca on March 2, enabling the vaccination of older people. Factors associated with this include the effect of different intervals on protection after the second dose, and the risk of infection between doses either due to lower efficacy of a single dose or rapid waning of efficacy while waiting for the second dose. So they still recommend a second dose of the vaccine.

To understand these factors, the authors combined data from randomised controlled trials in the UK, Brazil, and South Africa, including 8,948, 6,753, and 1,477 people, respectively (totalling 17,178 people).


The government has not advised this vaccine for people above 65 years.

Also Wednesday, Mexico " s Defense Secretary, Gen. Luis Cresencio Sandoval, announced he had tested positive for COVID-19. The state was to have received more than 30,000 doses of the Pfizer and Moderna vaccines this week, but so far, that hasn't happened.

The listing by the United Nations health agency comes days after a WHO panel provided interim recommendations on the vaccine, saying two doses with an interval of around 8 to 12 weeks should be given to all adults, and can be used in countries with the South African variant of the coronavirus as well.
