The new SARS-CoV-2 variant is already spreading in the US and could be dominant by March, the CDC warns. Here’s what that means for the masks you choose and how you practice social distancing.
Achieving high COVID-19 vaccine uptake among health workers will not only protect these critical staff members, it will also support high levels of uptake among the general public.
Critics of the South African government argue that it has done too little too late to secure vaccines, and that it doesn’t have a proper plan in place for rollout.
A biologist who studies the evolution of diseases explains what’s different about the two new virus strains that have been found recently, and what that means for vaccine effectiveness.
Rollout of COVID-19 vaccines has begun. But getting the jab doesn’t mean abandoning masks, distancing and handwashing. Here’s why the current preventive measures must continue post-vaccine.
It’s unlikely South Africa will have a substantial number of vaccines until the second half of this year. Most of the vaccines produced in Europe or America have been bought by other countries.
Creating a space where people feel safe to voice opinions, make mistakes and risk ridicule when offering an idea can have a significant effect on teams.
Massive vaccine distribution efforts take a lot of coordination. The rollout of the Salk polio vaccine in the US in 1955 holds lessons for those delivering COVID-19 shots today.
When a community reopens its schools and COVID-19 rates increase, other factors – not the reopening of schools – may still be to blame, new research finds.
In our first weekly update on COVID vaccines, we consider how roll-out plans are being tweaked and when it’s likely we’ll start to see vaccines having an impact.
