Minimal Effectiveness Predicted for 2023 flu Vax Campaign

As an adult medicine physician, every year I am personally confronted with the decision on annual influenza vaccination

As a former student, intern, resident, attending physician and professor of medicine working in large medical centers, I took 40 flu-shots over the years in keeping with medical staff requirements.

For this entire time, I have never taken an influenza test for viral infections.

What am I or anyone getting out of annual influenza vaccination?

Fowlkes et al, published interim data from REVELAC–i Network and the results of influenza vaccination March through July, 2023, from the Southern Hemisphere are disappointing.

Systematic monitoring of influenza and COVID-19 vaccine effectiveness (VE), is conducted through the Pan American Health Organization’s Network for the Evaluation of Vaccine Effectiveness in Latin America and the Caribbean–influenza (la Red para la Evaluación de Vacunas en Latino América y–i])† el Caribe—influenza [REVELAC-i].

The overall rate of influenza vaccination among patients hospitalized for severe respiratory illnesses was 23.9 percent. Of those hospitalizations, 32.4 percent tested positive for influenza. No deaths were reported.

Fowlkes AL, Nogareda F, Regan A, Loayza S, Mancio JM, Duca LM, Couto P, Leite J, Rodriguez A, Salas D, Azziz-Baumgartner E; REVELAC–i Network. Interim Effectiveness Estimates of 2023 Southern Hemisphere Influenza Vaccines in Preventing Influenza-Associated Hospitalizations – REVELAC-i Network, March-July 2023. MMWR Morb Mortal Wkly Rep. 2023 Sep 15;72(37):1010-1015. doi: 10.15585/mmwr.mm7237e1. PMID: 37708084; PMCID: PMC10511266.

Because patients were not randomized, adjustment is required to calculate theoretical vaccine efficacy.

As you can see, the vaccine efficacy for older adults, the high-risk group of concern, was a paltry 37.6 percent with the lower bound of the confidence interval at 13.1 percent.

To recommend a vaccine clinically, I demand at least 50 percent vaccine efficacy, and since the point estimate is a statistical blur, I conservatively look at the lower bound of the confidence interval.

None of the high risk groups met this clinical acceptance criteria to recommend influenza vaccination this year.

Thus, influenza vaccination will not be recommended in my practice for this influenza season.

    The clown show that is big pharma flu vaccines would have you believe that without your annual flu injection you are at risk of dying from flu complications. I have failed for the last 50 years to get my flu injection, so I guess I have died 50 times and didn’t know it.

    @ “I took 40 flu-shots over the years in keeping with medical staff requirements.”

    Sad! Experts should have asked for the efficacy data based on testing the vaccine against the virus. They would have found that vaccines have never been tested against the viruses. So, they could have avoided getting injected and injecting others. Alas, they do not know how vaccines are developed. They are simply fake. (https://bioanalyticx.com/covid-and-science-divergence/).

    It appears that they are now finding it out, but they still believe that viruses exist and vaccines are helpful. Experts should start reconsidering their views and beliefs.

    The flu vaccines have been completely reformulated and now contain mRNA . Avoid them at all costs .

    Hi Peter and other medical professionals,

    I regularly watch reruns of M.A.S.H. and from time to time one character is a health professional who uses ancient, primitive methods of healing. Copernicus began questioning the idea, that the Earth stood still, which had been accepted for about 2000 years.

    Do you modern health specialists ever question how did humans survive for thousands of years without your ‘modern’ knowledge?

    Have a good day
