Because these infections are mild in the first place, infections for those who are fully vaccinated have a gift from nature. They now have what is called a “hybrid vigor immunity.”
A review published in the journal Science explains the theory of “hybrid vigor immunity” in which the combination of natural immunity and vaccine-generated immunity results in a “larger-than-expected immune response.” Hybrid vigor is a scientific concept in botany in which two plant lines are bred to create a stronger hybrid version because of the combination of genetic traits from the two parents.
For the concept of hybrid immunity, the combination would be of two types of stimulation to the immune system in the forms of natural infection and vaccination. The authors of the review suggest that this could happen with immunity because a broader range of immune cells, including both B and T cells, could get activated.
