Lipopolysaccharide (LPS) is one of the major constituents of the gram-negative bacterial cell envelope. Its endotoxic activity causes the relatively high reactogenicity of whole-cell vaccines. Several bacteria harbor LPS-modifying enzymes that modulate the endotoxic activity of the LPS. Here we evaluated whether two such enzymes, i.e., PagP and PagL, could be useful tools for the development of...

Inactivated influenza virus vaccines (IVVs) are used for prevention of influenza and its complications. Present vaccines are immunogenic, of low reactogenicity, and protective, but protection has varied between 0% and 100%. Increasing the dose of hemagglutinin and neuraminidase antigens with purified proteins significantly increased serum and nasal antibody responses; however, trials with newer...

Abstract Stimulation of the innate immune system is crucial in both vaccinations and immunotherapies. This often achieved through adjuvants, molecules that usually activate pattern recognition receptors (PRRs) stimulate two signaling pathways: nuclear factor kappa-light-chain-enhancer activated B-cells pathway (NF-κB) interferon regulatory factors (IRF). Engineering response via fine control th...

We evaluated the reactogenicity and antigenicity of a quadrivalent rotavirus vaccine composed of serotype 3 rhesus rotavirus (RRV) and three single-gene-substitution reassortants of RRV and human strain D (D x RRV, serotype 1), DS1 (DS1 x RRV, serotype 2), or ST3 (ST3 x RRV, serotype 4) in a double-masked study with 302 infants in Caracas, Venezuela. Three doses of the quadrivalent vaccine comp...
