A vaccine? A cure?
I've read that this corona virus is a strain of the same virus as the common cold.馃

There are 7 identified Coronavirus types.
4 of these are always in regular circulation in the population. They are "the common cold".
The other 3 are far more serious in that they cause worse condition (in some) and due to being "novel" (ie something not seen regularly by human immune systems) more infectious etc. These are the MERs-Cov one, the original SARS-CoV one and now SARS-CoV-2 which can lead to Covid-19 (which is the disease not the virus).
Regarding strains. All viruses are constantly mutating. Actually of SARS-CoV-2 we know of at least 6 main ones already.

@Carla that's the fun isn't it... Trying to outsmart nature. We will lose.
However if you get one or two vaccines useful against the virus generally then you keep tweaking them, such as we do with flu vaccine every year.
Remember that with a vaccine you essentially make something very similar to the virus so when you introduce it the human immune system "learns" to fight it with appropriate antibodies and Tcells. As long as it's close enough then it will be effective.
Several methods to get that. Oxford University are using a Chimpanzee coronavirus that doesn't affect humans but triggers a close enough response. Others like Imperial are essentially artificially making a cell from rna strips that "looks" like a virus but is harmless.

@SW-User well...ive trusted flu vaccines for 20 years. I've been fortunate that they either work or, well, I am just fortunate. I will however, wait till a couple have been circulated. The first shingles vaccine is what comes to mind.
