While most people might guess that Israel or the UK hold the title, the tiny island nation of Seychelles is actually the most vaccinated country on earth, with more than 62% of its adult population already "fully vaccinated", according to a BBC report.
However, despite the fact that the island nation is closing in on the herd immunity threshold, the country and its public health officials have been forced this week to reimpose restrictions due to a surge in COVID-19 cases.
All schools in the country have been closed and sporting activities cancelled for two weeks in the country, which is spread across an archipelago in the Indian Ocean.
Measures also include a ban on inter-household interaction, some types of in-person gatherings, and the early closure of shops, bars and casinos. Non-essential workers are also being encouraged to work from home, while a 2300 local time curfew has been revived.
There are currently 1.07K active Covid cases in the Seychelles, of which a third have been detected in people given two doses of either AstraZeneca's or China's Sinopharm's vaccine.
It unclear what has triggered the surge in cases but testing has detected the South African variant spreading on the islands. Scientists believe the mutant strain can evade immunity and make jabs up to 30 per cent weaker at preventing infections — but they think Western vaccines should still stop people falling severely ill if they get infected. But because Seychelles is not actively analyzing a large amount of positive tests (something the UK and other countries are doing to monitor the spread of variants) it is difficult to tell exactly which strain has taken hold in the country.
