Scientists are experimenting with three kinds of COVID-19 vaccines
It is unlikely the first vaccines developed will be 100 percent effective and easy to produce on a massive scale. Realistically, researchers will develop a number of good-enough vaccines that can be produced using different kinds of manufacturing infrastructures. While these vaccines may at first have a limited efficacy, the diversity in manufacturing processes will allow companies to make and distribute them quickly, buying time and helping contain the current epidemic and prevent future outbreaks.
