Researchers studying a cohort of 787 health care workers have found that the Pfizer COVID-19 vaccine not only loses its efficacy within a few months, but drops by a whopping 57% by six months after the second dose, to about 33%.

The news was in stark contrast to Pfizer’s report that its shot has 95% efficacy, and to the CDC’s claim that it has at least 90% efficacy. The latest findings of 33% are even lower than the 42% reported in a Pfizer/Kaiser Permanente study published in The Lancet.

The decline affects all age groups, researchers said.
