Breakthrough Infection
A Breakthrough Infection (pronunciation: /ˈbreɪkθruː ɪnˈfɛkʃən/) is a case of illness in which a vaccinated individual becomes sick from the same illness that the vaccine is meant to prevent.
Etymology
The term "Breakthrough Infection" is derived from the English words "breakthrough," meaning an instance of achieving success in a particular sphere or activity, and "infection," which refers to the process of infecting or the state of being infected. In this context, it refers to the virus "breaking through" the protection offered by the vaccine.
