Thursday, Saudi Arabia’s National Scientific Committee for Infectious Diseases announced that one dose of the COVID-19 vaccine should be sufficient for those who have been previously infected with the virus, according to the Kingdom's Ministry of Health.

The ministry noted that the dose for recovered coronavirus patients would be administered six months after their recovery, noting that the vaccine would be considered an immunity booster.

Earlier Thursday, the ministry launched the second phase of their national vaccination campaign across all regions of the Kingdom, adding that those wishing to take the vaccine can book an appointment through the 'Sehhaty' app.

The Kingdom also approved the AstraZeneca-Oxford COVID-19 vaccine for use, according to the Saudi Press Agency (SPA).
