Impact of Prior Exposure to Anisakis simplex Antigens on Immune Response During SARS-CoV-2 Vaccination.
Parasitic infections can induce immunomodulatory effects that may influence host responses to vaccination. Chronic exposure to Anisakis antigens could modify T-cell and antibody profiles, potentially affecting SARS-CoV-2 vaccine effectiveness in endemic populations. We aimed to determine whether prior exposure to Anisa...
