As the Covid-19 pandemic wreaks havoc in South Africa and across the globe, millions are dying and getting infected. Inoculating (vaccinating) a significant proportion of the population is the only realistic way to defeat the pandemic, globally and locally. This will require international co-operation and social solidarity, not vaccine apartheid, nationalism and corporate profiteering. Unprecedented unity and action of all sectors of our society are of great urgency. Our people will need to show great vigilance and social solidarity if we are to slow the rate of infection and ensure that our health facilities do not continue to be overwhelmed.

The Covid-19 pandemic has severely affected the world’s people. Millions have been infected by the virus and billions of people’s livelihoods and lives have been negatively impacted upon.
