The SARS-CoV-2 Vaccines
It is said that the difference between the SARS-CoV-2 coronavirus (COVID-19), which is causing the pandemic around the world we are currently suffering from, and other coronaviruses like SARS and/or MERS is that SARS-CoV-2 ability to replicate in the human bodies' respiratory system’s upper airways more than the others. This capability makes it easier for SARS-CoV-2 to transmit, therefore, more transmissible when people talk, cough or sneeze.
