Scientists say. Covid natural immunity doesn't last as long as the vaccine. And that the vax gives better protection vs covid than natural immunity.
If you have a problem with this, go argue with the scientists. Don't shoot the messenger.

Hello, I have a question that I can't seem to find a answer so I'll ask here.
If a person catches covid19 and recovers they have natural immunity. Then the person gets the vaccine for covid as advised by the authority's. 4 to 6 months later a booster shot is needed because antibodies/spike protein/ protection/ whatever is gone.
Does this mean the vaccine has taken away the natural immunity?

The vaccines promote 'natural' immunity creating antibodies to the spike protein, which is the most immunogenic feature of the virus.
For example, the biggest immune response to the 'natural' virus, is to the spike protein which presents itself on the very most outer parts of the virus. It is the most obvious part of the virus for out immune system to detect. It is also the best target for a vaccine, that is why EVERY vaccine company has based their vaccines on the spike protein.
It is 'natural' immunity to the virus that begins to reduce after 3-7 months. Because 'natural' immunity is neither perfect, nor forever (and it never was, for any disease, that is why they are still diseases).
The same reduction goes for vaccinated immunity.
This is also why some people get COVID-19 more than once (even some people here on ATS have had the virus more than once, and some of those ATS members have also been rather strident about never getting the vaccine, despite being living proof that natural immunity hasn't protected them).

Integrin inside-out activation is tightly regulated by an intracellular sequence of events initiated by signals from several receptors. In leukocytes, these include G protein–coupled receptors activated by chemokines or inflammatory cytokines (Figure 3A), as well as the B-cell receptor or T-cell receptor (TCR) activated by antigens.
The term immunothrombosis, coined in 2013 by Engelmann and Massberg,2 formalized this concept and described a process by which the activation of coagulation assists the function of the innate immune system, and the converse, whereby components of the immune system contribute to thrombosis. Dysregulated activation of the immune system can thus contribute to the genesis of pathological macro- and microvascular thrombosis.
