Abstract: The present disclosure relates to vaccine compositions comprising a) antigens from at least three different strains of influenza vims, preferably at least four different strains of influenza vims, and b) an oil-in-water emulsion adjuvant, wherein the amount of the oil-in-water emulsion adjuvant is greater than an amount of an oil-in-water emulsion adjuvant in a standard-dose adjuvanted multivalent influenza vaccine. Additionally, the total amount of the antigens in the vaccine compositions may be greater than a total amount of antigens in a standard-dose adjuvanted multivalent influenza vaccine. In preferred aspects, the present disclosure further describes uses of these vaccine compositions for safe and effective induction of immune responses in adults at least 65 years of age.

Abstract: A catalyst for acid-catalyzed hydrocarbon conversions, in particular for the alkylation of olefins with isoparaffins, containing a crystalline zeolite with an SiO2—Al2O3 molar ratio of <10, the alkali cations of which are at least partially replaced by H+ ions and/or polyvalent cations, the residual concentration of alkali cations amounting to less than around 0.2% by weight, the concentration of the Bronsted centers, determined as a function of the pyridine chemisorbed on the catalyst surface, amounting to around 0.1 to 4 mmol/g of catalyst, and the ratio between the concentration of the acid centers of the Bronsted type (B) and of the Lewis type (L), expressed as the surface ratio of the absorption bands at 1540 ±5 cm?1 (B) and 1450 5 cm?1 (L) after heating to a temperature of 450° C amounting to around 1.4 or higher, is described.
