Many countries cannot afford to buy existing COVID-19 vaccines, a collective approach is needed.
With vaccine shortages looming, experts are debating whether it is important to receive two doses or whether it's better to give one dose to more people and give a second when the supply is better.
Researchers say around 70% of the US needs to get the coronavirus vaccine to stop the pandemic. But questions around the vaccines and regional differences add some uncertainty to that estimate.
So far, the only COVID-19 vaccines authorized for use need to be kept frozen. But there are many places in the world that can't support a cold supply chain.
With vaccines forthcoming for most Americans, many groups, including expectant mothers, are wondering if the vaccine is safe for them and their babies. A physician-scientist explains.
COVID-19 vaccines have very specific storage requirements that make shipping a difficult task. Two ideas – fulfillment centers and cross-docking – could help overcome some distribution challenges.
We should applaud drug companies for developing COVID-19 vaccines in record time, but let’s not be under any illusion about the profits that are motivating them.
Millions of Americans say they won't get the vaccine. Will money change their minds? And is luring them with cash the right approach?
The vaccines that will first be used to prevent the spread of COVID-19 will have gone through a special approval process with the FDA. but just what is this expedited process?
The side effects of new SARS-CoV-2 vaccines are a result of immune system activation. While uncomfortable, they are both normal and expected. They are a sign that the vaccine is working.
Because Pfizer-BioNTech and Moderna vaccines have been developed in record time, many wonder whether companies cut corners or compromised safety.
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?
There are two new COVID-19 vaccines that appear to be more than 90% effective. But what are these vaccines, and how are they different from those used previously?

With COVID-19 cases soaring across the US and worldwide, the need for a vaccine could not be greater. Here's where we stand on vaccine development, including positive results from Pfizer's trial.
So-called mRNA vaccines are among the frontrunners in the global race to design a COVID vaccine. But as a new technology, most nations, including Australia, lack the capacity to produce them at scale.
Both Moderna and AstraZeneca have used cutting-edge designs to reduce their vaccines' development time.
