Globally, healthcare workers (HCWs) are at greater risk of contracting Hepatitis B virus (HBV) infection than the general population, due to their frequent contact with blood or body fluids. For this reason, WHO underlined the importance of HBV immunization for all HCWs. Although sex is now considered one of the key factors influencing the intensity and duration of the immune response to vaccines, sex-specific analysis of vaccine-induced anti-HBs antibodies is rarely conducted.

Immunoglobulins (Igs) are produced by B lymphocytes and play a key role in humoral immunity. Igs are classified into five isotypes (IgG, IgA, IgM, IgE, and IgD). Their primary function is to recognize and bind to foreign antigens.

Cyclic peptides are often used as scaffolds for the multivalent presentation of drug molecules due to their structural stability and constrained conformation. We identified a cyclic deca-peptide incorporating lipoamino acids for delivering T helper and B cell epitopes against group A Streptococcus (GAS), eliciting robust humoral immune responses. In this study, we assessed the function-immunogenicity relationship of the multi-component vaccine candidate (referred to as VC-13) to elucidate a mechanism of action.

Recently, there has been significant interest in developing combination adjuvants to achieve efficient vaccines. However, it remains uncertain which combinations of adjuvants could best enhance the immune response to the recombinant antigen. In the current study, to improve the immunogenicity of Plasmodium falciparum cell traversal protein for ookinetes and sporozoites (PfCelTOS), we tested three different adjuvants: MPL, Poly I:C, and QS-21 alone or in a triple mixture (MPL/Poly I:C/QS-21; MPQ) and a dual mixture (Poly I:C/QS-21; PQ).

Interim results demonstrated strong humoral and cellular immune response against the SARS-CoV-2 Wuhan-Hu-1 strain and the Beta, Delta, and Omicron BA.1 variants up to day 98 post-dosing.
