A monovalent vaccine contains a single strain of a single antigen (e.g. Measles vaccine), whereas a polyvalent vaccine contains two or more strains/serotypes of the same antigen (e.g. OPV).
A monovalent vaccine is designed to immunize against a single antigen or single microorganism. A multivalent or polyvalent vaccine is designed to immunize against two or more strains of the same microorganism, or against two or more microorganisms.
What does inactivated vaccine mean?
An inactivated vaccine (or killed vaccine) is a vaccine consisting of virus particles, bacteria, or other pathogens that have been grown in culture and then lose disease producing capacity. Inactivated vaccines are further classified depending on the method used to inactivate the virus.
Which vaccines are live and which are inactivated?
Live virus vaccines use the weakened (attenuated) form of the virus. The measles, mumps, and rubella (MMR) vaccine and the varicella (chickenpox) vaccine are examples. Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria
How do inactivated vaccines work?
Children with weakened immune systems—for example, those who are undergoing chemotherapy—cannot get live vaccines. Inactivated vaccines also fight viruses and bacteria. These vaccines are made by inactivating, or killing, the germ during the process of making the vaccine.
Newcastle disease vaccines lasota strain the vaccine is made of AN inactivated virus of Newcastle disease Birds strain lasota in a mix with and oil adjuvant. the vaccine represent the homogeneous emulsion off white colour. at storage insignificant stratification of an emulsion is the top part of the vial which uniformity is resolved at agitation is allowed. the vaccine is packaged of 5000 vaccine doses in glass of plastic vials of the corresponding capacity.
