"We want to make this as easy as possible. We're not there to put barriers in the way, but we do want to ensure that we are observing safety protocols," said Sconaid McGeachin, senior vice president of communications at Expo 2020, in an interview with Dubai Eye radio. So what are the rules for visitors? No, visitors only need to show either proof of vaccination or proof of a negative PCR test taken within the previous 72 hours. Residents who live in the UAE can use the <a href="https://www.thenationalnews.com/uae/government/2021/08/19/abu-dhabi-new-entry-rules-how-to-download-the-al-hosn-app-ahead-of-august-20-changes/" target="_blank">Al Hosn app</a>. Visitors to the UAE are also encouraged to download the app and <a href="https://www.thenationalnews.com/uae/government/2021/08/14/abu-dhabi-rules-how-to-verify-international-vaccine-certificates-to-enter-public-places/" target="_blank">add their international vaccine certificate</a> details and unified identification number, which is issued on arrival in the country. Expo 2020 Dubai will also permit tourists to show vaccination certificates issued by their national governments. Certificates will be accepted as proof of vaccination. Paper certificates will be accepted. Vaccination certificates look different all over the world, however Ms McGeachin said officials from the 192 country pavilions are working closely with Expo 2020 Dubai to provide examples. Only visitors over 18 need to show proof of vaccination or a negative PCR test. It is not necessary for children, including those on <a href="https://www.thenationalnews.com/uae/education/more-than-1-million-school-trips-to-expo-2020-dubai-planned-1.926641" target="_blank">school trips, </a>to do so. If the vaccine is recognised in the visitor's country, and they have been issued with a certificate, then Expo 2020 Dubai will accept it. Yes, vaccination is mandatory for the entire Expo workforce, and <a href="https://www.thenationalnews.com/uae/expo-2020-dubai-country-participants-urged-to-join-vaccination-drive-1.1218748" target="_blank">free vaccinations</a> are available for official representatives of all countries taking part in the world fair. Yes, there is a large <a href="https://www.thenationalnews.com/uae/expo-2020/2021/09/05/what-are-the-covid-19-rules-at-expo-2020-dubai/" target="_blank">PCR testing facility</a> adjacent to the Expo 2020 Dubai site. However, the results take four hours, so organisers recommend visitors who need a PCR certificate get tested beforehand. Yes, if you show your Expo 2020 Dubai ticket you can get a free PCR test. This can be done either at the testing centre at the fair or at a special clinic that will be announced this week on the<a href="https://www.expo2020dubai.com/" target="_blank"> Expo 2020 Dubai website</a>. Training of the entry staff is ongoing, Ms McGeachin said. "We have been looking at how to train our staff to look at all the certificates, and to ensure that we make it as seamless as possible for people entering." People who cannot take the vaccine can show their medical exemption certificates, however we would encourage people to still take the PCR tests.
