Pathogens for inactivated vaccines are grown under controlled conditions and are killed as a means to reduce infectivity and thus prevent infection from the vaccine. [1] Inactivated vaccines were first developed in the late 1800s and early 1900s for cholera, plague, and typhoid. [2] In 1897, Japanese scientists developed an inactivated vaccine ...
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 killed ...
A conjugate vaccine is a type of subunit vaccine which combines a weak antigen with a strong antigen as a carrier so that the immune system has a stronger response to the weak antigen. Vaccines are used to prevent diseases by invoking an immune response to an antigen, part of a bacterium or virus that the immune system recognizes. [ 2 ]
Toxoid vaccines are made from inactivated toxic compounds that cause illness rather than the microorganism. [58] Examples of toxoid-based vaccines include tetanus and diphtheria. [58] Not all toxoids are for microorganisms; for example, Crotalus atrox toxoid is used to vaccinate dogs against rattlesnake bites. [59]
A tetanus vaccine is being administered at the Naval medical Center San Diego A toxoid is an inactivated toxin (usually an exotoxin ) whose toxicity has been suppressed either by chemical ( formalin ) or heat treatment, while other properties, typically immunogenicity , are maintained. [ 1 ]
For example, the live attenuated influenza vaccine is given nasally and is associated with nasal congestion. [25] Compared to inactivated vaccines, live-attenuated vaccines are more prone to immunization errors as they must be kept under strict conditions during the cold chain and carefully prepared (e.g., during reconstitution). [3] [22] [23]
Flu vaccines used during the flu in 2009. This is a list of vaccine-related topics.. A vaccine is a biological preparation that improves immunity to a particular disease.A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe or its toxins.
