Various institutions including the United States Center for Disease Control & Prevention have defined the event of a person receiving the full COVID-19 shot doses and later on falling ill with the virus regardless as a “breakthrough” case, implying that it is a rare event.
Data stemming from the United Kingdom and many other nations seem to paint a different picture regarding breakthrough cases, with recent numbers indicating that COVID-19 infection rates among jabbed patients are now similar or higher in all age groups of 30 or older.
