20220175908 · 2022-06-09 ·

The present invention relates to methods and vaccine compositions for inducing a safe immune response against polio virus in a human subject in need thereof, comprising administering to the subject a composition comprising inactivated Sabin poliovirus (sIPV) strains, wherein the sIPV strains have been produced on PER.C6® cells.

Immunogenic composition having improved stability, enhanced immunogenicity and reduced reactogenicity and process for preparation thereof

An immunogenic composition comprising of Diphtheria toxoid antigen (D), tetanus toxoid (T) antigen, Hepatitis B surface antigen (HBsAg), inactivated whole-cell B. pertussis (wP) antigen, Haemophilus influenzae type B (Hib) capsular saccharide conjugated to a carrier protein, Inactivated Polio Virus (IPV) antigen and additionally one or more antigens and the method of preparing the same. A fully liquid combination vaccine, showing improved immunogenicity, reduced reactogenicity and improved stability. Improved methods of formaldehyde inactivation, improved adsorption profile of Diphtheria toxoid antigen (D), tetanus toxoid (T) antigen and Hepatitis B (HepB) surface antigen adsorbed individually onto aluminium phosphate adjuvant, minimum total aluminum content (Al.sup.3+) and optimized concentration of 2-phenoxyethanol (2-PE) as preservative.

ATTENUATED VIRUSES USEFUL FOR VACCINES

This invention provides an attenuated virus which comprises a modified viral genome containing nucleotide substitutions engineered in multiple locations in the genome, wherein the substitutions introduce synonymous deoptimized codons into the genome. The instant attenuated virus may be used in a vaccine composition for inducing a protective immune response in a subject. The invention also provides a method of synthesizing the instant attenuated virus. Further, this invention further provides a method for preventing a subject from becoming afflicted with a virus-associated disease comprising administering to the subject a prophylactically effective dose of a vaccine composition comprising the instant attenuated virus.
