| 20080241180 | Liquid Vaccines For Multiple Meningococcal Serogroups - Conjugated capsular saccharides from meningococcal serogroups C, W135 and Y are safe and immunogenic in humans when combined in a single dose. This effect is retained when a conjugated capsular saccharide from serogroup A is added. These conjugated antigens can be stably combined in a single aqueous dose without the need for lyophilisation. Broad protection against serogroup B infection can be achieved by using a small number of defined polypeptide antigens. These polypeptide antigens can be combined with the saccharide antigens without loss of protective efficacy for any of the five serogroups. Efficacy if retained even if a Hib conjugate is added. The efficacy of a serogroup W135 conjugate is enhanced by addition of protein antigens derived from a serogroup B strain. Addition of a Hib conjugate to meningococcal conjugates enhances the overall activity against meningococcus serogroup W135. | 10-02-2008 |
| 20090035326 | COMPOSITIONS WITH ANTIGENS ADSORBED TO CALCIUM PHOSPHATE - Calcium phosphate is used as an adjuvant, with a high degree of antigen adsorption to the adjuvant. The invention is particularly useful for adjuvanting conjugated capsular saccharide antigens. Buffers, such as phosphate or histidine buffers, can advantageously be used in combination with the calcium phosphate, and compositions may have a pH in the range of 5.5 to 7.5. | 02-05-2009 |
| 20090155305 | Manufacture of Vaccines That Contain Both Hepatitis B Virus Surface Antigen and Surfactant - When preparing HBsAg for use in a combination vaccine, it is known to add a non-ionic detergent after the HBsAg has been purified. Adding detergents after purification of HBsAg is not optimal, however, as it requires a separate processing step during manufacture. Thus the invention uses them during HBsAg purification. | 06-18-2009 |
| 20090214586 | Combination Vaccines With Whole Cell Pertussis Antigen - Vaccines have been studied that comprise (a) D-T-Pw-HepB-Hib antigens and (b) one or more meningococcal conjugate antigens. A number of improvements and variations of these vaccines have been discovered. The vaccines can be prepared extemporaneously at the time of use by mixing together two components: (a) a first component comprising D, T, wP and HBsAg antigens; and (b) a second component comprising a Hib conjugate and one or more meningococcal conjugates. | 08-27-2009 |
| 20090220547 | Reducing interference between oil-containing adjuvants and surfactant-containing antigens - Inclusion of fatty adjuvants in vaccine compositions can cause difficulties with certain antigenic components, particularly with antigens that include a surfactant component. A method for preparing an immunogenic composition comprising an antigen and a fatty adjuvant involves purification of the antigen substantially in the absence of surfactant. Where surfactants cannot be avoided, the following are combined: (i) an antigen component that includes a surfactant and (ii) a fatty adjuvant component, to give a composition in which the weight ratio of said fatty adjuvant to said surfactant is less than 1000:1. | 09-03-2009 |
| 20090285854 | FROZEN STOCKPILING OF INFLUENZA VACCINES - A problem with stockpiling influenza vaccines is their short shelf life. Storage volume is another problem. The invention prepares and stockpiles bulk vaccine, and the bulk is stored under frozen conditions. Compared to final vaccine, the higher antigen concentration and absence of packaging materials (boxes, vials, etc.) in the bulk means that the storage space requirements are hugely reduced. A process for preparing an influenza vaccine bulk thus comprises the steps of: (a) preparing bulk vaccine antigen from a source of influenza virus; and (b) storing the bulk vaccine prepared in step (a) under frozen conditions. | 11-19-2009 |
| 20090304742 | INFLUENZA VACCINES WITH REDUCED AMOUNT OF EMULSION ADJUVANT - Influenza vaccines with oil-in-water emulsion adjuvants are known. The amount of emulsion adjuvant required for an influenza vaccine can be reduced, thereby allowing more vaccines to be made from a given amount of emulsion, and/or minimizing the amount of emulsion that has to be produced for a given number of vaccine doses. These vaccines can conveniently be made by mixing (i) an oil-in-water emulsion and (ii) an aqueous preparation of an influenza virus antigen. In one aspect, substantially equal volumes of components (i) and (ii) are used; in another aspect, an excess volume of component (ii) is used. When using substantially equal volumes, component (ii) has a hemagglutinin concentration of more than 60 μg influenza virus strain per ml. Components (i) and (ii) can be presented in kit form. | 12-10-2009 |
| 20100143418 | Immunising Against Meningococcal Serogroup Y Using Proteins - The invention uses polypeptide antigens and/or OMVs to immunize against serogroups A, C, W | 06-10-2010 |
| 20100203137 | FORMULATION OF MENINGITIS VACCINES - A liquid Hib component is used to reconstitute a lyophilised meningococcal component, thereby producing a combined meningitis vaccine. A lyophilised meningococcal component can also be reconstituted with an oil-in-water emulsion. | 08-12-2010 |
| 20100226937 | COMBINATION VACCINES WITH 1-HYDROXY-2-PHENOXYETHANE PRESERVATIVE - Processes for preparing combination vaccines that include diphtheria and tetanus toxoids, where these two toxoids are used in the processes as a single component containing both toxoids, and also containing 1-hydroxy-2-phenoxyethane. | 09-09-2010 |
| 20100285069 | MENINGOCOCCAL VACCINE FORMULATIONS - A dual formulation for vaccines against | 11-11-2010 |
