Mixing doses of the Oxford AstraZeneca and Pfizer BioNTech covid-19 vaccine leads to more frequent mild moderate reactions compared with standard dosing schedules, researchers have reported. Researchers running University led Com-COV study—which is investigating reactogenicity immunogenicity from mixing two vaccines—reported their preliminary results in a peer reviewed research letter Lancet ....
Acellular vaccines against diphtheria-tetanus-pertussis (acellular pertussis) (DTaP) are being progressively introduced into vaccination programs worldwide, with the aim of reducing T-helper 1 (Th1)-associated reactogenicity associated with the cellular diphtheria-tetanus-pertussis (whole-cell pertussis) (DTwP) vaccine. The DTaP vaccine has an improved safety profile in infants, but little info...
To elucidate the role of innate responses in vaccine immunogenicity, we compared early responses to hepatitis B virus (HBV) surface antigen (HBsAg) combined with different Adjuvant Systems (AS) in healthy HBV-naïve adults, and included these parameters in multi-parametric models of adaptive responses. A total of 291 participants aged 18-45 years were randomized 1:1:1:1:1 to receive HBsAg with A...
Seasonal influenza vaccine formulations must be updated annually to correspond to the influenza viruses in circulation. This was an uncontrolled, open-label, multi-center phase IV study conducted in Belgium to comply with interim European Medicines Agency (EMA) guidelines for rapidly evaluating the safety of newly formulated seasonal influenza vaccines. Adult volunteers received one dose of the...
BACKGROUND Pfs25 and Pvs25, surface proteins of mosquito stage of the malaria parasites P. falciparum and P. vivax, respectively, are leading candidates for vaccines preventing malaria transmission by mosquitoes. This single blinded, dose escalating, controlled Phase 1 study assessed the safety and immunogenicity of recombinant Pfs25 and Pvs25 formulated with Montanide ISA 51, a water-in-oil em...
BACKGROUND & OBJECTIVES A phase 1 trial of adeno-associated virus based HIV-1 subtype C vaccine (tgAAC09) was conducted at two sites in Germany and Belgium and one site in India. This paper reports the safety and immunogenicity of tgAAC09 in healthy adult Indian volunteers. METHODS Between January 2005 and December 2006, 30 consenting volunteers were enrolled in the placebo controlled double-...
BACKGROUND We conducted a Phase I dose escalation trial of ADVAX, a DNA-based candidate HIV-1 vaccine expressing Clade C/B' env, gag, pol, nef, and tat genes. Sequences were derived from a prevalent circulating recombinant form in Yunnan, China, an area of high HIV-1 incidence. The objective was to evaluate the safety and immunogenicity of ADVAX in human volunteers. METHODOLOGY/PRINCIPAL FIND...
Most subunit vaccines require adjuvants in order to induce protective immune responses to the targeted pathogen. However, many of the potent immunogenic adjuvants display unacceptable local or systemic reactogenicity. Liposomes are spherical vesicles consisting of single (unilamellar) or multiple (multilamellar) phospholipid bi-layers. The lipid membranes are interleaved with an aqueous buffer,...
