It's higher than that. 17.2 million out of an adult population of nearly 40 million are said to be fully vaccinated. Reuters reckon it's 38% though.
Not according to this site which I think is fairly reliable https://ourworldindata.org/covid-vaccinations That states 25% fully vaccinated and another 5% partially vaccinated Did Reuters give a source?
Unfortunately not. The BBC say the same though. The Daily Maverick - a SA online newspaper - reckons it was 38% full, 7% partial as at 5 December. https://www.dailymaverick.co.za/art...-mistakes-during-the-ongoing-vaccine-rollout/
So according to Plan B you can only shop in Asda without a mask if you go round singing Knee's up mother Brown or any song of such ilk.
