Some governments of world countries maybe have very high target for their researchers to immediately find out "best vaccine" in a very very short period.
But we know that researchers are also human being who has limitations in their work. How to support their work through the maintains of their circadian rhythm (that maybe different from common people) in order to "always" have high performance in their works ?
Personally, I think having a realistic expectation, so as to not compromise the quality of a vaccine (efficacy, sufficient antibodies in plasma generated during actual infections) , and to ensure its utmost safety (minimal to no side effects) is most important, coupled by more government spending since research requires alot of funding.
