The problem with vaccines are that, the virus does mutate very quickly, basically the virus is a single-stranded RNA, positive sense, helical capsid, and enveloped. So to break that down a little bit, basically a positive sense RNA virus is very similar to mRNA, mRNA is basically the genetic code that gets translated into proteins in you body, which proteins obviously have a vast variety of functions. Because of that it means that human hosts immediately translate this into protein. Now, the capsid is like a shell almost for the virus, and enveloped means that the capsid is coated with fats, this is also acquired by the host. This basically ends up protecting the genetic make up of the virus and allows for it to communicate with hosts. The protection is very strong, it protects it from stuff like radiation, acids, temperature, etc. Then, we gotta understand that RNA viruses mutate more than DNA viruses, and this is because RNA viruses kind of lack a "proof-reading" function that DNA viruses do. That's the whole basis of how the viruses is changing itself. The timing is sensitive, and it's the regulation more of having to do clinical trials, which is necessary to assess side effects, efficacy, etc. It's just really hard to try to streamline that process to make an effective vaccine.
I did see the reports out on Chloroquine seeming to be pretty effective. It's undergoing the clinical trial phase for Coronavirus actually. This is a basically a drug used to treat Malaria. The way it works for Coronavirus is a little bit different than what it does for Malaria. It basically goes into one type of your cells, makes that environment more basic, and then interferes with another process that allows for the virus to get into your cells. Chloroquine is actually a pretty relatively safe drug, so I could see that becoming one of treatments moving forward. The other drug they researched that seemed to be effective was the anti-viral Remdesivir, which was seen as promising for SARS/MERS, and is clinical development for treatment of Ebola. I have think that one may be a little tougher to get in the United States, so this is true. I still do think that these treatments will be held off unless it's for severe cases, with the typical treatment being still the quarantine and letting your immune system fight off against it however. Sorry for all the medical jargon, hopefully I simplified it well enough to be followed, because I do think us as the medical community are very bad at communicating in ways that people can understand, and that can lead to fears.
Yup, that's the thing, it's incredible difficult to try to follow up with recovery cases, not to mention the amount of people who might have had it, mistaken it for the common flu, and never went to go get it checked out. It's definitely something I think people should be weary about, but I definitely think a lot of the fear is from not exactly knowing what's going on about the virus, and what it's characteristics and stuff are. Ultimately, we don't know everything about this virus, but we do know the general characteristics of Coronavirus to be able to help communicate and hopefully negate some of the worries. Obviously if there's any questions by anybody here, I'm more than happy to try to simplify it a bit more and make some analogies that will make sense! I also want to express I'm in no way trying to be combative or anything, in case any of this comes off as arrogant or what not. Just enjoy a good discussion about medicine from time to time!
