This study looked at how the body changes inside after a COVID vaccine or infection by checking blood proteins. It found that vaccines wake up the body's first responders, especially in people who never had COVID before. If someone had COVID before, their body reacts differently. When vaccinated...
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

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.
When vaccinated people get COVID anyway, their bodies seem to switch into a stronger, more targeted immune mode that uses special immune cells to fight the virus better.
Getting your first COVID vaccine when you've never had the virus seems to turn on key parts of your immune system that help fight off infections, especially by boosting certain immune cells and signals that protect against viruses.
Getting the COVID vaccine barely changes the proteins in your blood, but actually catching the virus causes big shifts in those same proteins.
