specifically?
I'm not a virologist. So I don't know the specifics of any of these candidates. However, the ones moved to clinical trials should obviously be the most promising.
Of all the candidates, the live/attenuated and inactivated viruses would be the most traditional ones. I actually am more hopeful of these.
Of the newer techs established in the field of oncology, I would be more cautious. In terms of immunal therapy, the field of oncology is very different than a viral infection. Because cancer is a terminal illness and has very few effective treatment options, we have much less strict requirements for a cancer-treating immunal therapy. Usually, if you can show that one patient (yes, that's not a typo. A single patient data is enough) gets better with the treatment, that's good enough for everyone to agree to continue. Because cancer patients face almost certain death, any option is better than not doing anything... Even if that means severe side effects (shortening your life by 10-20 years), because being able to live an extra week becomes a luxury for these patients. That's why oncology usually has lower standards for drug safety. On the other hand, the standards for a coronavirus infection that kills only 4% of the infected should be so much higher. So I would say the strategies that work in oncology may not work in COVID-19. Let's see what happens...
