SAN ANTONIO – We have been living with COVID-19 for the better part of 2020. The virus has infected millions of people, killed hundreds of thousands around the world and upended our daily lives.
Many people believe life will return to normal with a vaccine. It’s not that simple.
In this week’s episode of KSAT Explains, which can be streamed in the video player above, we examine the challenges to create a potential vaccine, how they are tested and how long it takes before a vaccine can safely be introduced into the general population.
According to The New York Times, there are more than 165 COVID-19 vaccine trials underway.
The trials are broken up by phases and some of the research is being conducted in San Antonio.
Below is a video that explains how San Antonio is involved and a chart from the CDC which shows the vaccine life cycle.
