The electronic wristband ensures the traveller adheres to a 14-day mandatory quarantine period to prevent the spread of Covid-19. The tag is removed at a medical facility after to its wearer receives a negative PCR nasal swab test on day 12 of quarantine. Similar rules are in place in other countries as researchers around the world work to develop a Covid-19 vaccine. On Friday, the World Health Organisation said more than 170 countries had joined its global plan to <a href="https://www.thenational.ae/world/coronavirus-live-who-says-170-countries-have-joined-global-vaccine-plan-1.1071399">distribute vaccines fairly around the world</a>. It also cautioned that a race to develop shots could lead to public fears about safety. “We already face challenges with vaccine acceptance for many proven vaccines,” said WHO chief Tedros Adhanom Ghebreyesus. “We cannot risk having an effective vaccine for Covid-19 that people refuse because of the perception that it is unsafe.” Globally, coronavirus cases reached 30 million on Thursday, while the death toll approaches one million. In the UK, the British government is preparing to <a href="https://www.thenational.ae/world/europe/uk-government-could-use-emergency-powers-to-push-through-unlicensed-vaccine-1.1079393">invoke emergency powers</a> to allow the use of a coronavirus vaccine for the public, even if it has not met EU licensing requirements, the <em>i</em> newspaper reported. The UK would use its own emergency regulations to bypass EU law and roll out a vaccine for use if one became available before the end of the Brexit transition agreement on December 31.
