When people say the vaccine was developed in a short amount of time, that isn't technically correct. This is a novel virus, but the vaccine was years in the making. The tech behind these vaccines started development for SARS/MERS, but fell flat because those threats diminished.
When SARS-CoV2 came along, scientists already had a blueprint on how to develop a vaccine for it, using over a decade of research. All these viruses are Bat-CoVs. They just had to make it specific for SARS-2 and go to trials, then solve mass production. This wasn't a fast fix.
So many people say it takes over a decade to develop a vaccine. And that decade was spent on this one as well. Further, consider the flu vaccines are modified year to year, it doesn't take decades to do that.
There are dozens of known Bat-CoVs. So far, few have jumped to humans. We're lucky Sars2 wasnt the virus that entered human populations in 2002, it would have been far more damaging than it is today because it would have taken 5-6 years to get a vaccine. Our luck was SARS & MERS.
For those interested in the science.
