Join The Conversation for a virtual discussion with leading scientists about what life will be like with the COVID-19 vaccine.
Two pharma companies have announced early COVID-19 vaccine trial results with over 90 per cent effectiveness. What does that mean for getting back to normal?
The Great Barrington Declaration's advocacy for naturally acquired herd immunity to COVID-19 amounts to a global chickenpox party: naive and dangerous.
A resurgence of the coronavirus in South Africa is almost impossible to avoid, but the timing and extent depend on people's behaviour.
Some have suggested the US allow healthy people to return to normal life, catch the coronavirus and get the population to herd immunity. The science says this plan is doomed to fail from the start.
With a vaccine, yes, elimination is possible. But we need to be realistic about how long this might take.
Social distancing can get tougher in the fall and winter. These simple steps can help keep you and your loved ones healthy.
Vaccines only work if enough people take them.
Control of an infectious disease through build-up of natural immunity has never been achieved before, and there's no reason to believe COVID-19 is any different.
People aren't uniform in how they behave – nor in how they spread disease. At a population level, that makes a difference.
Herd immunity has entered the everyday language, but it is a much misunderstood term.
Our best shot at ending the pandemic is by achieving herd immunity through widespread use of a vaccine. But that won't happen unless people believe it's safe.
This is just one person. Is he the exception? Is he the rule? We don't know yet for sure. But reinfection is definitely possible.
Current rates of vaccine hesitancy could jeopardize efforts to achieve herd immunity in the US, says Matt Motta, a political scientist who studies vaccine uptake and effective health communication.
Once a coronavirus vaccine is approved, billions of doses need to be manufactured. Current vaccine production is nowhere near ready, for a variety of reasons, but planning now could help.
But will the new normal only be feasible for the well off?
Natural herd immunity is a myth.
Researchers can't agree on topics such face mask, immunity and number of infections. Here's why.
Despite a lighter lockdown, Sweden hasn’t avoided the damaging economic disruption experienced elsewhere.
We'll achieve herd immunity when 60% of the population is immune to COVID. No, wait, make it 70%. Or is it 80%?
