[Ed. – Well, gee whiz.  In other words, the efficacy of the vaccine appears to decline significantly with time.  P.S.  I don’t know why the headline at Fox says “twice ‘more’ likely” to contract the infection.  It’s repeated in the text.  The actual numbers indicate they mean “twice ‘as’ likely.”]

Moderna Inc. has released a set of data which suggested its COVID-19 vaccine is effective in preventing serious health issues or death from “variants of concern” but admitting that efficacy decreases over time, such that those who received the vaccine last year were twice more likely to contract a breakthrough case of the coronavirus disease.

According to the data, which Moderna released Wednesday, a “study shows lower risk of breakthrough infection in participants vaccinated more recently (median 8 months after first dose) than participants vaccinated last year (median 13 months after first dose).”

A Moderna trial conducted over the summer, labeled Phase 3 COVE Study, revealed that “88 breakthrough cases of COVID-19 occurred in the more recently vaccinated group (49.0 cases per 1000 person-years) compared to 162 cases in the group vaccinated last year (77.1 cases per 1000 person-years).”
