What are the problems the searchers are facing in development of CoVID19 vaccine?
When is the vaccine likely to be available?
Who are in the field?
news item of today: Canada now also approved clinical trials for their vaccination candidate, see https://www.ctvnews.ca/health/coronavirus/health-canada-approves-first-clinical-trial-for-potential-covid-19-vaccine-1.4942507
The current status is: 11 phase I clinical trials and, certainly, some candidates will fail. Phase I trials need to be followed by phase II and III trials (efficacy, side effects, dosage etc.) and, if a candidate proves effective, by licencing through the responsible authorities. All this will still take a while.
@Christian G Meyer
about your overview of 11 trials - do you have a source? Thank you!
4 trials are to my knowledge in Phase 2, with human clinical trials...
As I carefully checked, to be developped totally a vaccine requires 20 to 25 years..so what is all this rush for the covid-19 case? is it even possible to start trials already? Even they will be successful, these early trials are kind of suspicious for me, because they do not follow the same path of other vaccines!
This overview page by Germany's pharma industry gives an impression of 68 COVID-19/SARS-CoV-2 vaccination projects currently under way. Normally it would take 15-20 years. Now many shortcuts are taken... https://www.vfa.de/de/englische-inhalte/vaccines-to-protect-against-covid-19

BREAKING NEWS ABOUTS COVID-19 VACCINE
Moderna's COVID-19 Vaccine Shows Promise, Generating Positive Immune Responses in an Early Study

It is important to note that the development of a vaccine is a long process that goes through several stages of clinical trials. When a vaccine is injected in the body, it trains the body’s immune system to fight a particular pathogen. As of now, there are over 100 potential vaccines worldwide in different stages of development.

Don't set a lot of unrealistic expectations on vaccine. Good health at old age is more important and fundamental than vaccine. Even with vaccine, a lot of people still die from flu and its complications every year. Such death can be largely avoided, if the person has good health.
There are some misunderstandings about immunity. Immunity is not only our body's protective mechanism against microbial infection. Moreover, immunity is the only way for our body to obtain the essential nutrients from the microorganism community, so as to remain us in good health.
Although each microorganism is a potential pathogen, will cause infection and immune responses in our body, try to gradually expose ourselves to the microorganisms around us as much as possible. And after we have developed antibodies against the microorganisms, don't wipe these microbes out of our body by the antibiotics. The microbiome within us is the best and only nutrition source for our body. And bear in mind that good health cannot be built in short time. It may take years or tens of years to get the immunity against all the microorganisms around and inside us (the diverse human microbiome) and benefit from these microbiome to secure our health.
So many pharmaceutical companies are striving hard to launch an effective COVID-19 vaccine. Now Pfizer pharmaceuticals announces that a COVID-19 vaccine will be available in October 2020.

After tall claims all appears stalled regarding COVID-19 vaccine?
Simple reason is that SARS-CoV-2 causes a short lived immunity like the Coronaviruses causing common cold.
