Vaccines usually requires years of research and testing before reaching the health center, but scientists are battling to stock a secure and operative coronavirus vaccine by next year.
Researchers are testing 37 vaccines in clinical trials on humans, and a minimum of 91 preclinical vaccines are under active investigation in animals.
Work began in January 2020 with the decrypting of the SARS-CoV-2 genome.
The primary vaccine safety trials in humans started in March, but the road ahead remains uncertain. Some trials will fail, et al. may end without a transparent result. But a couple of may achieve stimulating the system to supply effective antibodies against the virus.
