Lying by Omission about Break-Thru Covid-19 Infections?

[Celerity]

14. these insanely high claims for effectiveness against infection are bullshit, pure and simple

here is a reply I did in regards to another OP

The OP claimed



this tweet kicked it off

Link to tweet

They are literally claiming that vaccines, across the board, all vaccines, all variants, have a 99.924% effectiveness rate at preventing infection.

Their exact words (and similar massively inflated numbers in those tweets in THIS new OP I am replying to) were

Chances of Vaccinated Catching Covid

They did not say having symptomatic illness, or say having severe illness, or requiring hospitalisation, or say ending up with ICU level illness and/or death.

No, they said simply catching the infection.

This is simply untrue.

1. The CDC doesn't even track non hospitalised breakthrough cases for vaxxed people.

2. The actual scientific studies show that at BEST (Pfizer against the origin strain) the top-performing vaccine had a 95% or so efficacy rate at preventing infection. That is down to (again with the best vax results) 80% against Delta for the Pfizer vax at preventing infections, (88% efficacy are preventing symptomatic disease). J & J is far worse across the board, 66-72% for the origin strain, and now studies are showing as low as 33% against Delta (and that is just preventing symptomatic disease, NOT stopping all infections). Against certain variants, certain vaccines are a complete fail. The non US-used (but massively used in other nations) AstraZeneca vaccine, for instance, only has a 10.4% efficacy rate versus the Beta (B.1.351 aka South African) variant.

3. Efficacy from clinical trails is very often higher than real world EFECTIVENESS.

To make it ULTRA simple: If the Pfizer vax efficacy (the actual real world effectiveness was lower, around 90%) was 95% against THE ORIGIN STRAIN (which was massively less potent than Delta) that means 5% (and 10% in the real world) BREAKTHROUGH infections. 10 out of every 100 Pfizer vaxxed people had breakthrough infections, and that was against the origin strain, not Delta.

The other vaccines were lower, and especially lower (including Pfizer) against the variants.

To claim these 99.9+% real world effectiveness rates against any infection (which they are claiming) is a dangerous lie.
