There are 10 or more vaccines being tried out all over the world. They all have names that sound like nonsense and don’t tell you anything very much about what they are – like AZD1222 and NVXCoV2373.
But they all have two things in common:
1) They all contain harmless stuff that is also found in bits of the virus. (Or maybe harmless stuff that is *almost* the same as what is found in the virus.) The idea being that if your body has seen this stuff in advance then it recognises the virus immediately and deals with it very quickly. This is the way all vaccines work.
2) They are all still being tried to see if they work. We need to be patient until all the results are analysed.

There are a bunch of different vaccines that different research institutions and companies work on all over the work so the list is pretty long. For example there is a 5-page list by the WHO here: https://www.who.int/publications/m/item/draft-landscape-of-covid-19-candidate-vaccines
And there is also a number of different approaches to the vaccine:
1) using inactivated virus as the vaccine
2) using parts of inactivated virus as the vaccine
3) using genetic information that encodes parts of the virus so the body produces for example the surface proteins and then the cells can ‘learn’ how these look
Here is a youtube video that explains those vaccines in development quite well I think 😉
