Stopping the spread of COVID-19 variants

COVID-19 vaccines

When a virus is widely circulating in a population and causing many infections, the likelihood of the virus mutating increases. The more opportunities a virus has to spread, the more it replicates – and the more opportunities it has to undergo changes. Stopping the spread at the source remains key. Current measures to reduce transmission – including frequent hand washing, wearing a mask, physi...

To stop stronger COVID-19 variants from emerging we need to work together globally

COVID-19 vaccines

Ensuring equitable access to COVID-19 vaccines is more critical than ever to address the evolving pandemic. If some parts of the world eliminate the virus while it spreads widely in other areas, we all run the risk of stronger strains evolving. We’re only safe when everyone is safe.
