RECOMBINANT VACCINE AGAINST COVID-19 BASED ON A PARAMYXOVIRUS VIRAL VECTOR
Described is a recombinant vaccine, active or inactivated, against COVID-19, which comprises a Newcastle's disease viral vector and a pharmaceutically acceptable vehicle, adjuvant and/or excipient, the vaccine being characterised in that the viral vector is a virus capable of generating a cellular immune response and has an inserted exogenic SARS-CoV-2 nucleotide sequence.
The invention relates to a recombinant vaccine comprising a vector of avian adenovirus serotype 9 (FAdV-9) with an inserted exogenous sequence of nucleotides coding for an antigen of a disease of interest and replacing the non-essential region of the genome of the adenovirus; and a pharmaceutically acceptable vehicle, adjuvant and/or excipient; where the exogenous sequence of nucleotides is between the nucleotides 491-2782. The vector of this recombinant vaccine is stable when it is produced at an industrial level. Likewise, the recombinant vaccine, even when administered in combination with a vaccine against Marek's disease, produces a suitable immune response that is not affected by the interference caused by said vaccine against Marek's disease nor does the Marek's vaccine inactivate the vaccine according to the invention. This recombinant vaccine allows the barrier of the maternal antibodies to be broken or avoided, inducing a suitable immune response.
A live or inactivated recombinant vaccine is described, comprising a viral vector and a pharmaceutically acceptable vehicle, adjuvant and/or excipient, wherein the viral vector is capable of generating a cell immune response due to an increased alpha and/or gamma interferon production, and is capable of a quick replication, and it has inserted a nucleotide sequence of the ORF 5 and ORF 6 from PRSS.
A live or inactivated recombinant vaccine is described that comprises a viral vector and a pharmaceutically acceptable vehicle, adjuvant and/or excipient, which is characterized in that the viral vector is a virus capable of generating a cellular immune response owing to an increased production of alpha and/or gamma interferon and capable of replicating rapidly, and a PRRS ORF 5 and ORF 6 nucleotide sequence is inserted therein.
A vaccine is described comprising an inactivated viral vector having inserted therein an exogenous nucleotide sequence encoding for a disease of interest, together with a pharmaceutically acceptable vehicle, adjuvant or excipient, providing due protection against the disease of interest through use of a concentration of the viral vector similar to that required for an active virus vaccine based on the same viral vector. Principally viral vectors of paramyxovirus or adenovirus are described.
A combination is described that has coccidiocidal effects and is composed of toltrazuril and trimethoprim. Also described are veterinary compositions in which said combination is used, wherein the veterinary compositions have a potentiated effect that enables birds to recover more rapidly and to have fewer disease sequelae, and there is no precipitation of the active ingredients in the combination when those ingredients are used with hard water.
