- Abstract
Introduction: Influenza or SARS-CoV-2 vaccination is especially recommended for people with underlying diseases. For the large number of patients with chronic hepatitis B virus infection (CHB), studies on their immune responses to these vaccines are still lacking. Methods: A total of 57 CHB patients and 19 healthy controls (HCs) receiving inactivated influenza vaccination were prospectively followed up. Influenzaspecific immunoglobulin G (IgG) antibodies (anti-H1N1, anti-H3N2, and anti-B IgG), antibody-secreting cells (ASCs), and circulating T follicular helper cells were assessed simultaneously. Eight CHB patients subsequently got inactivated SARS-CoV-2 vaccination during 1-year follow-up, and levels of serum antibodies against SARS-CoV-2 were further analyzed. Results: On day 28 after influenza vaccination, three influenza antibodies levels appeared to be lower in CHB patients than in HCs. And anti-H1N1 IgG level was significantly decreased in cirrhotic patients (p < .05). Anti-H1N1 IgG levels (day 28) were positively correlated with ASC frequencies (day 7) (p < .05), and negatively correlated with cirrhosis and hepatitis B surface antigen levels (p < .05). Anti-SARS-CoV-2 antibodies were higher in patients with influenza vaccination history than in patients without the history (p < .05). Moreover, positive correlations existed between influenza vaccination history and anti-SARS-CoV-2 antibody levels (p < .01). Conclusions: CHB patients, especially those with cirrhosis, appeared to have a decreased antibody response to inactivated influenza vaccine. A history of inactivated influenza vaccination within 1 year before inactivated SARS-CoV-2 vaccination might induce stronger anti-SARS-CoV-2 antibody response.
