 A Danish cohort study demonstrates that breakthrough infections can not be avoided. Artificial overstimulation of the immune system with older strains can even lead to negative protection, aftern some months, when new variants emerge.

 A high percentage of the world population has currently aquired natural immunization after encountering one or more variants of the virus, therefore it can be considered that this type of infection has become endemic like traditional flu and will be recurrent in the following years. Omicron has worked as a natural immunizer and this is helping to reach herd immunity.
