Egypt began administering jabs to frontline medical staff against COVID-19 on Sunday using the vaccine developed by China National Pharmaceutical Group (Sinopharm).

The vaccine will be provided free of charge first to all doctors and frontline workers treating coronavirus patients, then to other medical workers, senior citizens and people with chronic illnesses, Health Minister Hala Zayed said.

"As soon as each citizen registers, they will take their turn. But you cannot set a timeframe for when this will be, and even the countries that have set a timeframe have not been able to fulfil it, not because they have a problem, but because of the global production issue," Zayed said, adding that Egypt was on track to approve three other vaccines for use.

The North African nation has recorded a total of 161,143 cases, including 8,902 deaths, since the pandemic started. Health officials say the real number of infections is likely far higher because of the relatively low rate of coronavirus testing and exclusion of private test results from official figures.

Zayed previously said Egypt was expecting 40 million doses via the GAVI vaccine alliance, covering 20 million of the country's 100 million population.

She said on Sunday the country had secured an additional 40 million vials from one company and 20 million from another, without specifying their origin but bringing the total to 100 million doses.
