mRNA Vax: Immune System Still in Overdrive?

Just read a wild study: a year after getting the Pfizer mRNA COVID vax, young people still had higher levels of immune system signals (cytokines) in their blood. The immune system seems to stay revved up for months, and the effect is even stronger in men and older adults. Researchers think this could be from the body still making spike proteins. Kinda makes you wonder what that means long-term, right? #COVID19Vaccine #mRNA #ImmuneSystem #HealthNews #ScienceUpdate #Health
