Mr Obeidat said
another field hospital was planned in Irbid and two more in the port city of Aqaba and the southern city of Maan.
The three planned hospitals will have a combined capacity of 766 beds.
The king invoked emergency legislation in March to deal with the coronavirus and last month authorities reimposed a curfew as the number of deaths rose sharply.
Officials say that the authorities are considering lifting the curfew imposed since early November, particularly a ban on movement all-day on Fridays.
On weekdays the curfew lasts from 10pm to 6am.
Mr Obeidat said the government was expected to receive one million Pfizer-BioNTech vaccine doses by the first quarter of 2021.
