In South Africa, vaccines quickly turned from a supply problem to a demand worry. About 28 percent of the population is vaccinated and 24 percent fully vaccinated, according to Our World in Data figures up to November 24-higher than many other African countries but well below the government target for the end of the year. South Africa has seen a slower vaccination rate than many Western countries. Only 59 cases have been confirmed so far, but scientists are concerned about it spreading and potentially proving resistant to vaccines. The variant has been found in Hong Kong, Israel and Botswana, as well as South Africa. It is said to have twice the number of mutations as the highly transmissible Delta variant. The Omicron variant has 32 mutations of its spike protein and has been described as the "most worrying we've seen" by the chief medical adviser to the U.K. The WHO has previously called for vaccine equity and has said new variants of the coronavirus are most likely to emerge in unvaccinated parts of the global population. Several governments have imposed travel restrictions on the country in the past 24 hours. His post sparked criticism on social media, with some Twitter users pointing out that vaccine supply no longer seemed to be a problem in South Africa, where the Omicron variant has been recorded.
