Coronavirus is a large family of pathogens. Each strain of coronavirus is not equally dangerous, four strains (types) of coronavirus cause mild illnesses like the common cold. Covid tests are the only way to know if you have it for sure. The three others can cause fatal infections. One of them is SARS-CoV-2 that causes COVID-19. SARS-CoV-2 stands for severe acute respiratory syndrome coronavirus 2.
Since the body has not been exposed to the novel coronavirus (SARS-CoV-2), our bodies aren’t well equipped to deal with COVID-19. A vaccine would allow the body to safely develop an immune response to COVID-19 that could prevent or control infection. As some of the vaccines are at later stages of Phase-3 Clinical Trials, they would still take an estimate of 8-16 months to develop for worldwide use, so until then follow standard operating procedures (SOPs) to avoid the transmission of disease.
