new short section on vaccines

[egonw]

There is not a lot of vaccines in Wikidata yet (1 at this moment), but I can imagine I'll find some time to annotate some more next week.

Hello, Egon, I saw that you add somethings about vaccine candidates.

I have uploade somethings about vaccines on Wikidata: https://w.wiki/WkX

There was not a simple way of attributing labels, so I put the name of the developer. There are about 20 vaccine candidates for covid-19 on Wikidata now.

I tried to match them to a couple clinical trials too.
