S.Africa changes COVID vaccination rules to try to boost uptake

South Africa's health department said on Monday that it was changing COVID-19 vaccination rules to try to increase uptake, as inoculations have slowed and the country has ample vaccine stocks. The government is shortening the interval between the first and second doses of the Pfizer vaccine from 42 to 21 days and will allow people who have received two doses of Pfizer to get a booster dose three months after their second shot as opposed to six months previously. It will also offer the option of 'mixing and matching' booster jabs, with adults who were given one dose of Johnson & Johnson's vaccine being offered either a J&J or Pfizer booster two months after their J&J shot.
