The three COVID-19 vaccines available in the United States are safe and effective and were made in record time.
But they aren’t ideal.
An ideal vaccine — besides being safe and effective — would have a few other desirable characteristics, says Deborah Fuller, a vaccine researcher at the University of Washington.
Such a vaccine would be “administered in a single shot, be room temperature stable, work in all demographics and, even pushed beyond that, ideally be self-administered,” she says.
Now, researchers are racing to develop the next generation of COVID-19 vaccines, utilizing a variety of innovative technologies to produce more convenient and more potent options. Some of the new vaccines are already being tested in volunteers and could even be available for distribution in the next year or so.
