No disagreement there. since the rate of vaccinations in South Africa though is very low across all age groups , plus we don't know of those vaccinated how many people have the vaccines that have been deemed less effective such as J and J as well as others. the data lately is only measuring people with 2 shots : not the boosters so more data to come.. i read South Africa news daily on what's happening there and still no alarms other than the rate of the spread...which then brings into account masks. if this thing spreads like a cold are masks going to be effective ?
