So incredibly ugly, tacky, and unnecessary.

This study looks at how the immune system responds to various infections and stimulants after receiving the BNT162b2 COVID-19 vaccine (commonly known as the Pfizer vaccine).
Before vs. After Vaccination: After getting vaccinated (at a time point labeled "V2 + 28"), the immune system showed a weaker response in terms of specific immune-signaling chemicals (interferon-γ and monocyte chemoattractant protein-1) when exposed to various bacteria and viruses, compared to before getting vaccinated.
Cytokine Changes: Other immune-signaling chemicals (IL-6, IL-15, IL-17) were also generally decreased when the body was exposed to most of these stimulants after vaccination.
Viral vs. Bacterial: Interestingly, these weaker responses in immune-signaling chemicals (cytokines) remained lower for viruses but not for bacteria, six months after vaccination.
COVID-Specific Response: On the other hand, the immune response specifically to COVID-19 (SARS-CoV-2 and its spike proteins) was stronger at "V2 + 28" and remained stronger six months after vaccination.
No Correlation with Antibodies: The levels of COVID-specific antibodies in the blood (measured at "V2 + 28") did not relate to these changes in cytokine responses.
In plain English, the study suggests that after receiving the Pfizer COVID-19 vaccine, the immune system's general ability to signal and react to various infections decreases somewhat, at least in the short term. However, the ability to respond specifically to COVID-19 improves and remains strong for at least six months. These changes in the immune system's signaling ability don't seem to be connected to the level of COVID-specific antibodies in your blood.
