Two doses of the Pfizer vaccine leave people with more than five times lower neutralising antibodies – a key part of the immune system – against the Indian variant (Delta) when compared to the original coronavirus strain upon which current vaccines are based, the largest study of its kind suggests.

They also pointed out that levels of antibodies alone do not predict vaccine effectiveness and prospective population studies are also needed. Lower neutralising antibody levels may still be associated with protection against Covid-19, the experts said.
“The most important thing is to ensure that vaccine protection remains high enough to keep as many people out of hospital as possible. And our results suggest that the best way to do this is to quickly deliver second doses and provide boosters to those whose immunity may not be high enough against these new variants.”

He's saying. The vaccine he tested lowered your natural immune system antibody count.
It replaces your immune system with the spike protein.
That's the way I understand it.

Theoretically you are right. That's what the Pfizer shot is suppose to do and probably does. But it lowers your other natural antibodies.
Shouldn't mess with mother nature.

He nor you understand how these actually work man.
Best on your part to stop spreading crap.
You seem to do this often.
If you don't understand what he is saying that's your problem. Others that understand can hear what the Doctor has to say. We don't need permission from anyone.

But it doesn't lower your antibodies.
Shouldn't mess with mother nature? So you don't live in a house, built on a, once, natural area that was flattened for the purpose, ego messing with Mother Nature?
You don't take medicines which are created by extracting active ingredients from plants, ergo messing with Mother Nature?
Every human being on the planet, almost, messes with Mother Nature.

Here. Maybe this will help.
Real world data from PHE, published as a pre-print, demonstrated two doses of COVID-19 Vaccine AstraZeneca are 92% effective against hospitalisation due to the Delta variant and showed no deaths among those vaccinated. The vaccine also showed a high level of effectiveness against the Alpha variant (B.1.1.7; formerly the ‘Kent’ variant) with an 86% reduction of hospitalisations and no deaths reported.
The higher efficacy against severe disease and hospitalisation is supported by recent data showing strong T-cell response to COVID-19 Vaccine AstraZeneca, which should correlate with high and durable protection.
