THE RACE FOR COVID 19 VACCINES
More than 150 coronavirus vaccines are in development around the world - and there are high hopes to bring atleast one into the rescue in record time to ease the global crisis. In order to instruct the immune system to mount a defense, some vaccines need to use the whole coronavirus, but in a killed or weakened state. Others use only a part of the virus - like a fragment of the virus. Some transfer the coronavirus proteins into a totally different virus that is unlikely to cause disease or even incapable of it. Finally, after such prolonged months of extensive research, some vaccines under development rely on deploying pieces of coronavirus's genetic material, so our cells can temporarily make the coronavirus proteins needed to stimulate our immune systems. I would be posting some of the recent developments relating to COVID and vaccines, on a regular basis, whenever I can, to give you all some more insight into when an end for this pandemic is most likely to come. So let me begin
