SARS and MERS are a syndrome, or group of symptoms; not a virus. The virus family is Coronavirus. The specific Coronavirus is SARS-CoV2. SARS(group of symptoms) - Coronavirus(cause) 2(virus variant). COVID-19 is not a scientific name, it is a colloquial name - C(orona)VI(rus)D(isease)-(20)19; the Coronavirus caused disease discovered in 2019.
Most symptoms of a viral infection, are the result of your immune system carpet bombing everything to try and kill the virus. Those broad spectrum antibodies attack everything, including healthy tissue. Vaccines, give your immune system a peek at the virus, like a cheat sheet, so that when it encounters the virus, it recognizes it and can attack it directly. The reason virus variants are troublesome, is because the parts the immune system recognizes, might be different. This is why natural immunity is almost always better than vaccination; because the immune system has more parts of the virus to compare. But, if a surface component of the virus, the part your immune system sees first, is sufficiently different from whats 'on file', the result will be the same as infection by a new virus. This is why a cold causing Coronavirus infection, does not give immunity from SARS-CoV2, but may help fight it, once an infection has taken root; thus, the milder symptoms in some people.
