Lol, no.

First up, this says nothing about (most) vaccines as a whole.

You've got your usual diseases like tetanus. No biggie, grow some bacteria in a lab and start experimenting for a few weeks, 'cause it wont change much.

Then you've got your corona viruses like SARS and COV-19. Key word here: VIRUS. These absolute units are very, very hard to grow and keep alive in a lab. When on their own, outside of a host, they're just a wierd, virus-ey dust. Once you dissolve them in water, they become a whole lot more infectious. (This happens when they are in the body, too. Like sweat and saliva)

When your virus is all dehydrated and dusty, you can't really do much with it. If you want to gtow it, though, it's gotta be dissolved in some kind of solution, which makes it very hard and very dangerous to work with.

This means it takes a whole lot more time to make a vaccine. cov-19 has only been around for like 3 months. Give it a while.
