The health ministry said the programme would roll out in three phases, starting with people over 65 and those with chronic ailments or at high risk of infection.
Those over 50 years of age would be vaccinated next, with everyone else included in the third stage, and the vaccine would be free for citizens and residents as per the ministry statement.
The ministry confirmed the safety and efficacy of the vaccine after the effective passage of the vaccine testing phases, and the successful tests showed its strong immune response and antibodies in those who received trial shots.
Saudi Arabia has recorded more than 363,000 novel coronavirus cases, including more than 6,000 deaths -- the highest among the Gulf Arab states. But the kingdom has also reported a high recovery rate. Saudi Arabia has a population of more than 34 million, according to official figures.
