1.
Early life T cell responses to pneumococcal conjugates increase with age and determine the polysaccharide-specific antibody response and protective efficacy
Jakobsen H, Hannesdottir S, Bjarnarson S, Schulz D, Trannoy E, Siegrist C, et al.
Eur J Immunol . 2005 Dec; 36(2):287-95. PMID: 16385627
Immunization with a tetanus-protein (TT) pneumococcal polysaccharide (PPS) conjugate vaccine (Pnc1-TT) induces protective immunity against lethal pneumococcal infections in neonatal and infant mice, but anti-PPS IgG response and protective efficacy...
2.
The advantage of mucosal immunization for polysaccharide-specific memory responses in early life
Bjarnarson S, Jakobsen H, Del Giudice G, Trannoy E, Siegrist C, Jonsdottir I
Eur J Immunol . 2005 Mar; 35(4):1037-45. PMID: 15756644
The aim of vaccination is to rapidly elicit protective immunity and generate memory for sustained protection. We studied the induction and persistence of polysaccharide (PS)-specific memory in neonatal and infant...
3.
Protective levels of polysaccharide-specific maternal antibodies may enhance the immune response elicited by pneumococcal conjugates in neonatal and infant mice
Richter M, Jakobsen H, Haeuw J, Power U, Jonsdottir I
Infect Immun . 2005 Jan; 73(2):956-64. PMID: 15664938
Maternal antibodies (MatAbs) may protect the offspring against infections but may also interfere with their immune responses to vaccination. We have previously shown that maternal immunization with pneumococcal polysaccharides (PPS)...

Immunization of female mice with glycoconjugates protects their offspring against encapsulated bacteria
Richter M, Jakobsen H, Birgisdottir A, Haeuw J, Power U, Del Giudice G, et al.
Infect Immun . 2003 Dec; 72(1):187-95. PMID: 14688096
The immune system of the newborn is immature, and therefore it is difficult to induce protective immunity by vaccination in the neonatal period. Immunization of mothers during pregnancy against infections...
5.
Pneumococcal serotype 19F conjugate vaccine induces cross-protective immunity to serotype 19A in a murine pneumococcal pneumonia model
Jakobsen H, Sigurdsson V, Sigurdardottir S, Schulz D, Jonsdottir I
Infect Immun . 2003 Apr; 71(5):2956-9. PMID: 12704178
Immunization with a pneumococcal conjugate vaccine (PNC) containing serotype 19F induces cross-reactive antibodies to 19A in mice and human infants. Active immunization with PNC and passive immunization with serum samples...
6.
Intranasal immunization with pneumococcal conjugate vaccines with LT-K63, a nontoxic mutant of heat-Labile enterotoxin, as adjuvant rapidly induces protective immunity against lethal pneumococcal infections in neonatal mice
Jakobsen H, Bjarnarson S, Del Giudice G, Moreau M, Siegrist C, Jonsdottir I
Infect Immun . 2002 Feb; 70(3):1443-52. PMID: 11854231
Immunization with pneumococcal polysaccharides (PPS) conjugated to tetanus toxoid (TT) (Pnc-TT) elicits protective immunity in an adult murine pneumococcal infection model. To assess immunogenicity and protective immunity in early life,...
