IL-6 and IL-8 elevations after co-administration of COVID-19 and influenza vaccines are associated with lower anti-spike IgG titers at three and six months post-vaccination 🔥For those still in doubt: don’t take both vaccines together( →4-6 weeks). ➡️"Coordinated activation of cytokines 5 days after dual COVID-19 and Flu vaccination." ➡️"The IL-6 and IL-8 increase negatively correlated with anti-S IgG at 3- and 6-months." ➡️Subsequently the "Inflammatory cytokine response may limit persistence of vaccine-induced antibody response." ‼️So, co-administration may impair long-term COVID-19 antibody persistence due to early inflammatory cytokines (e.g., IL-6, IL-8) negatively correlating with mid-term IgG titers. sciencedirect.com/science/ar…
