What it Takes to Develop a Vaccine for Public Use

The Timeline Usually Takes Years

There are a few cases of vaccines reaching the full state of development and able to help people around the world within a year, but usually, the timeline is years. Many steps go into developing a safe vaccine, and then it needs testing. From there, you need to focus on approval from the FDA before it can make its way into hospitals and clinics. 

One of the most recent monthly cases was during the Zika outbreak between 2015 and 2016. It was another crisis that people weren’t ready for, but a vaccine reached development within seven months. To date, this is the fastest vaccine ever developed. But, this doesn’t mean that we can get a vaccine for the current crisis within this time frame, even if there are reports of a vaccine in the local news.
