The Claim
In individuals with prior SARS-CoV-2 infection, primary vaccination is associated with downregulation of proteins involved in the complement and coagulation cascade—such as fibrinogen chains and integrin subunit alpha M—indicating potential modulation of innate inflammatory and thrombotic pathways upon re-exposure to the viral antigen.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you've already had COVID and then get your first vaccine, your body might dial down certain blood clotting and inflammation proteins, which could mean your immune system is responding differently the second time around.
See the scientific wording
Primary vaccination in individuals with prior SARS-CoV-2 infection is associated with downregulation of proteins in the complement and coagulation cascade, including fibrinogen chains and integrin subunit alpha M, suggesting modulation of innate inflammatory and thrombotic pathways following antigen re-exposure.
What the research says
1 studyThe study shows that people who had COVID before and then got vaccinated had changes in blood proteins related to inflammation and clotting, which supports the idea that their bodies respond differently to the vaccine.
