The Facts: These vaccines could be made fast and still be safe for three simple reasons.
- There was a lot of research done on the kind of virus that causes COVID-19 before this virus showed up. So scientists had a big head start about the kind of vaccine that would work best to fight this virus.
- A lot of government money was spent to get many companies to work on this vaccine and to put all of their scientists to work on it around the clock. That helped speed everything up.
- While every step that has to be followed to make a new vaccine and be sure it is safe was followed, some of the steps were done at the same time instead of one after another. It is like cooking several parts of a meal at once instead of cooking one course at a time. You get done sooner but it’s just as good.
In fact, the two vaccines that have been approved to protect against COVID-19 were studied on more than 70,000 volunteers, including adults of all ages and different racial and ethnic groups, and were found to work very well and be equally safe for all.
