In 2008, following a rubella epidemic, the Egyptian Ministry of Health implemented a Measles Rubella (MR) catch-up campaign, based on WHO recommendations for supplementary immunization activities to eliminate measles by 2010. The age group targeted was 10–20 years. This campaign was unique in Egypt as it was the first national vaccination campaign which included university students.To report uptake...
We estimate the impact of the two previous influenza seasonal vaccines and the pandemic vaccine on risk of A (H1N1) 2009 laboratory confirmed hospitalizations during the autumn 2009 pandemic wave in Castellón, Spain. We conducted a test-negative, hospital-based, case–control study. Influenza A (H1N1) 2009 infection was detected in 147 (44%) of 334 patients hospitalized for a presumptive influenza...
Mucosal immunization with a killed whole-cell pneumococcal vaccine, given with enterotoxin-related adjuvants, has been shown to confer multi-serotype protection against colonization of the nasopharynx and middle ear in mice. However, because novel mucosal immunization strategies may be difficult to implement, here we evaluated subcutaneous injection. Strain RM200 was engineered to be capsule-negative,...
The efficacy of antibody immunity against Streptococcus pneumoniae stems from the ability of opsonic, serotype (ST)-specific antibodies to pneumococcal capsular polysaccharide (PPS) to facilitate killing of the homologous ST by host phagocytes. However, PPS-specific antibodies have been identified that are protective in mice, but do not promote opsonic killing in vitro, raising the question of how...
A cost-effectiveness analysis of rotavirus vaccination in Belgium, England and Wales, Finland, France and the Netherlands published in 2009 was updated based on recent studies on rotavirus burden of disease and vaccine efficacy. All the qualitative conclusions in the previous study were found to remain valid. Vaccination remains cost-effective in Finland only when using plausible tender prices.
Pregnant women are reluctant to be vaccinated during their pregnancy. Their main concern is the safety of influenza vaccine. We investigated the adverse reactions of pregnant women who received the influenza A (H1N1) 2009 virus vaccination and also conditions of neonates of the vaccinated women. Various adverse reactions developed after vaccination, but the symptoms were mild and resolved within several...
There is an unmet medical need for a prophylactic vaccine against herpes simplex virus (HSV). DNA vaccines and cutaneous vaccination have been tried for many applications, but few reports combine this vaccine composition and administration route. We compared DNA administration using the Nanopatch™, a solid microprojection device coated with vaccine comprised of thousands of short (110μm) densly-packed...
The study evaluated the immunogenicity and efficacy of a trivalent subunit MF59-adjuvanted influenza vaccine (A/Wisconsin/67/05 (H3N2), A/Solomon Islands/3/06 (H1N1) and B/Malaysia/2506/04) in preventing serologically diagnosed infections in a group of 67 institutionalized elderly volunteers during 2007/2008 winter, characterized by co-circulation of drifted A/H3N2, A/H1N1 and B influenza viruses...
Burkholderia thailandensis is a less virulent close relative of Burkholderia pseudomallei, a CDC category B biothreat agent. We have previously shown that lipopolysaccharide (LPS) extracted from B. pseudomallei can provide protection against a lethal challenge of B. pseudomallei in a mouse model of melioidosis. Sugar analysis on LPS from B. thailandensis strain E264 confirmed that this polysaccharide...
Rotarix™ was introduced into the Belgian market in 2006 and RotaTeq™ in 2007, quickly reaching more than 85% vaccine coverage of all newborns in Belgium. The incidence of rotavirus gastroenteritis has been monitored in the Gasthuisberg University Hospital (GUH), Belgium since 1986, and since 1999 the genotypes of circulating rotavirus strains have been determined. The average percentage of rotavirus...
Here, DNA replicon vaccines encoding the Hc domain of botulinum neurotoxin serotype A (AHc) or the receptor binding domain of anthrax protective antigen (PA4) with or without signal sequences were evaluated in mice. Strong antibody and protective responses were elicited only from AHc DNA vaccines with an Ig κ signal sequence or tissue plasminogen activator signal sequence. Meanwhile, there were no...
Attenuated Salmonella enterica offers a vaccine delivery route that has the benefits of enhanced immunogenicity and oral delivery. The majority of immunization studies have been conducted to deliver recombinant proteins, expressed from a gene that is either chromosomally integrated or carried on a low- or medium-copy number plasmid. There are, however, an increasing number of reports demonstrating...
Acceptability of human papillomavirus (HPV) vaccination seems to be high in the Western world but fewer data are available for men than for women. There are also concerns that HPV vaccination might lead young people to change their healthcare-related behaviours. We investigated these issues in a population-based survey performed in Sweden during January-May, 2007, just after HPV vaccination had been...
Regulatory T cells (T Reg ), CD4 + CD25 + FOXP3 + , are implicated in suppressing tumor immune responses. We analyzed peripheral blood lymphocytes (PBL) from breast cancer patients receiving a modified HLA class II HER2/neu peptide (AE37) vaccine for T Reg cells and correlated their levels with vaccine-specific immune responses. The mean CD4 + CD25 ...
Rotavirus vaccine was recommended for use in US infants to prevent rotavirus gastroenteritis (RGE) in February 2006. This matched case control study assessed the effectiveness of rotavirus vaccine in preventing hospitalization of young. Cases were vaccine-eligible children 8 weeks-3 years of age, hospitalized due to laboratory-confirmed RGE. Cases (n=42) were matched to 2 control groups: (a) hospitalized...
Porcine reproductive and respiratory syndrome virus (PRRSV) has recently caused heavy economic losses in swine industry worldwide. Current vaccination strategies only provide a limited protective efficacy, thus immune modulators are being considered to enhance the effectiveness of PRRSV vaccines. In this study, the recombinant adenoviruses expressing porcine CD40 ligand (CD40L) and GP3/GP5 of PRRSV...
A cross-sectional survey of Italian pediatricians and pediatric residents was carried out between 15 September and 18 October 2008 in order to evaluate their knowledge concerning the administration of vaccines to children with suspected or proved allergies. Of the 750 physicians who accepted to participate (620 pediatricians and 130 residents), 630 (84.0%; 407 females; mean age 43.5±11.2 years) returned...
There is a need for new adjuvants that will induce immune responses to subunit vaccines. We show that a short peptide, named Hp91, whose sequence corresponds to an area within the endogenous molecule high mobility group box (HMGB1) protein 1 potentiates cellular immune responses to peptide antigen and cellular and humoral immune responses to protein antigen in vivo. Hp91 promoted the in vivo production...
