Members of the public are comparing approved Covid-19 vaccines that have been rolled out worldwide and asking questions about which jabs are the safest and most effective. Some of these include the mRNA vaccines by Pfizer-BioNTech and Moderna and the viral vector vaccines developed by Oxford-AstraZeneca and Johnson & Johnson (J&J).
In South Africa, the J&J vaccine is being administered to healthcare workers during Phase 1 of the country's inoculation strategy.
Health Minister Zweli Mkhize recently announced that SA secured 20 million doses of the Pfizer vaccine.
