The COVID-19 virus is strong, highly contagious, rapidly mutable to survive in different environments, and it already outsmarted many of our leaders around the world. These days dramatic numbers and statistics demonstrate that the virus poses a severe life-threat to people with preexisting respiratory and heart conditions and immune system deficiencies, whatever their age.
People in good health and with an efficient immune system are resistant to the COVID-19 to the point that many of them become asymptomatic carriers. When a vaccine is released worldwide, it will fight the latest known versions of the virus at the time it was designed. But COVID-19 shifts and adapts to different environments around the world in a tight timeframe creating many strands not included in the vaccine at the time it will be made available to the market.
