Vaccine Comparison

rVCG- Chlamydia-cholera rVCG- MOMP/HSV-2-gD Synthetic OMP1 Vaccine
Vaccine Information Vaccine Information Vaccine Information
  • Vaccine Ontology ID: VO_0004720
  • Type: Recombinant vector vaccine
  • Status: Research
  • Host Species for Licensed Use: Baboon
  • Preparation: A multisubunit vaccine candidate co-expressing the serovar D-derived Porin B and polymorphic membrane protein-D proteins of Chlamydia trachomatis (Eko et al., 2011; Chen et al., 1998).
  • Immunization Route: Intramuscular injection (i.m.)
  • Vaccine Ontology ID: VO_0004722
  • Type: Recombinant vector vaccine
  • Status: Research
  • Host Species for Licensed Use: Baboon
  • Preparation: A bivalent combination vaccine formulation comprising rVCG expressing chlamydial MOMP and HSV-2 glycoprotein D (Macmillan et al., 2007).
  • Immunization Route: Intramuscular injection (i.m.)
  • Vaccine Ontology ID: VO_0004240
  • Type: Subunit vaccine
  • Status: Research
  • Antigen: Lipidic amino acid-based synthetic peptides derived from the variable domains (VD) of Chlamydia trachomatis outer membrane protein 1 (Zhong et al., 1993).
  • Adjuvant: NAGO
  • Immunization Route: subcutaneous injection
Host Response Host Response Host Response

Mouse Response

  • Vaccination Protocol: Mice were immunized with rVCG constructs (Eko et al., 2011).
  • Vaccine Immune Response Type: VO_0003057
  • Efficacy: All vaccinated mice responded with a significant rise in vibriocidal antibody titer, the surrogate marker for protection in cholera (Eko et al., 2011).

Mouse Response

  • Vaccination Protocol: Mice were immunized with the combination vaccine that elicited secretory IgA and IgG2a antibodies to both chlamydial and HSV-2 antigens in serum and vaginal secretions (Macmillan et al., 2007).
  • Vaccine Immune Response Type: VO_0003057
  • Challenge Protocol: Immunized mice then experienced a genital challenge with high doses of live Chlamydia and HSV-2 (Macmillan et al., 2007).
  • Efficacy: Mice immunized with the combination vaccine were prophylactically protected (Macmillan et al., 2007).

Mouse Response

  • Vaccination Protocol: 50 μg of peptide was injected subcutaneously with NAGO in PBS into the tail base, and was repeated at 14 day intervals (Zhong et al., 1993).
  • Immune Response: NAGO elicited an antibody response similar to that in mice immunized with CFA (Zhong et al., 1993).
