Human Challenge Trials to Speed up COVID-19 Vaccine Hunt

It is known that we have secured a number of safe and effective vaccines against COVID19, but it is also essential that we continue to develop new vaccines and treatments for Covid-19. These studies offer specific unique insights into how the virus works and also helps us to understand which promising vaccines offer the best chance of preventing the infection. There are few things to describe and analyze as to how much virus does it take to start an infection? How does the immune system begin its initial defense? And to tell which people will develop symptoms or not? The trials will start off by focusing on these fundamental scientific questions. We also must realize that there are also new vaccines coming up and the virus itself is evolving at a gradual speed.
