We are only at the beginning of the corona pandemic, the virus continues to mutate.

We are only at the beginning of the pandemic. The greater the number of infected people, the greater the number of mutations. The more mutations, the more dangerous and highly dangerous mutations.

Target achievable for the virus:

extremely easy transmissibility, simple masks become practically ineffective

no outbreak of the disease for weeks,
but nevertheless infection of other persons

at outbreak of the disease most severe symptoms, collapse of the health care system

Infection also of persons who were already ill with another virus variant,
thus no immunity due to previous illness with the "simpler virus type

effective vaccinations only with exact adaptation to the current virus mutations, similar to influenza, therefore only a success rate of max. 60%.

still unknown surprise factors, after all it is a new disease.
