So far, most vaccines in the US are mRNA vaccines. These represent a new technology and are likely to take over the vaccine world. But how do they work? What are their weaknesses? Five experts explain.
The coronavirus pandemic has driven a lot of scientific progress in the past year. But just as some of the social changes are likely here to stay, so are some medical innovations.
The Johnson & Johnson vaccine is different from the Moderna and Pfizer vaccines in a few important ways that could make it a huge help to global vaccination efforts.
With the vaccines now being administered at sites around the US, it is important to address misinformation surrounding the effort.
With slow vaccine distribution and manufacturing, some people won't get the second dose on time. But does it matter?
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.
