UAE residents who have received a first dose or booster vaccine in another country are reporting difficulties in uploading their subsequent overseas vaccines in the Al Hosn App. To resolve this, please visit a SEHA clinic in Abu Dhabi (no appointment needed). Medical staff will assess your vaccine details, upload them to Al Hosn and provide an exemption from needing a UAE booster after six months. This should keep your status Green after the 20 September 2021 grace period.
