They are at 42% efficacy according to Mayo Clinic study.
The Mayo Clinic study has the Moderna vaxx at about 60% VE for Delta; it was the Pfizer vaxx (you know....the foundation for the "approved" vaxx) at the lower 42% VE.
Here's the kicker in the Mayo study:
mRNA-1273 and BNT162b2 were originally designed, tested, and proven to reduce the burden of symptomatic disease, hospitalization, and death related to SARS-CoV-2 infection.
That's not entirely true. The FDA's approval memos clearly stated these shots are all about "prevention" and not lessened symptoms, shorter hospitalization, etc.
...It is important to realize that most vaccines are not 100% effective, particularly against asymptomatic infections. For example, the estimated effectiveness of seasonal influenza vaccines has ranged from 19-60% over the past decade.
Wow...welcome to the new world of diminished expectations.
While COVID-19 mRNA vaccines have been shown to be drastically more effective than this, the occurrence of breakthrough infections is indeed still expected. We observed a pronounced reduction in the effectiveness of BNT162b2 coinciding with the surging prevalence of the Delta variant in the United States, but this temporal association does not imply causality, and there are likely several factors contributing to changes in vaccine effectiveness over time.
Blah blah blah blah....straight, no chaser....they're not as effective as they were just a few months ago.
