The The Ministry of Hajj and Umrah has changed the Corona entry rules to Saudi Arabia. As before, entrants must present a negative PCR laboratory test upon arrival to begin the rituals of Umrah.
All individuals with a vaccine approved by Saudi Arabia's Ministry of Health have no quarantine requirement and may perform the Umrah directly. Approved vaccines are: Pfizer-BioNTech, Moderna, Oxford-Astrazeneca, and Janssen. Vaccination with other approved vaccines from the World Health Organization such as Sinopharm and Sinovac requires three days quarantine after entry and a negative PCR test afterwards.
