The UAE's Al Hosn app has been updated to serve as the national e-register for the Covid-19 vaccination campaign. The app already acts as a database for Covid-19 testing results and contact tracing. The National Emergency Crisis and Disasters Management Authority announced the new role for the app in a post on Twitter. The authority said the app can be used by an individual to demonstrate they have been vaccinated. “The data available in [the app] are official documents that prove vaccination, and people can save the record and print it whenever needed,” the tweet read. The announcement came as the chief executive of Dubai Airports, Paul Griffiths said he expected vaccine passports to become ubiquitous and mandatory for travel. NCEMA also underlined the efficacy of the vaccines available in the UAE against Covid-19, and the importance of herd immunity to combat the genetic mutation of the virus. The authority encouraged all individuals above the age of 16 to get the vaccine to protect themselves, their families and society. “As the number of vaccinated individuals increases, and they strengthen their immunity against Covid-19, the less likely it will be for the virus to grow and spread, which helps reduce the chances of more mutations and variants,” according to the NCEMA tweet. Studies to monitor the variation in the strains already prevalent in the UAE are being organised by the Ministry of Health and Prevention, in co-ordination with local laboratories and universities. A national team has been formed in the UAE to track the variant strains across all the emirates, and the health authorities are monitoring the new mutations, and the possible consequential rise in cases in some countries. Nearly 7.5 million people have received a vaccine in the UAE. The UAE recorded 2,196 new Covid-19 cases on Wednesday, taking its total to 446,594. Another 2,385 patients were given the all-clear as the recovery tally climbed to 429,573. Five patients died as the death toll rose to 1,456.
