An attenuated vaccine (or a live attenuated vaccine, LAV) is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). [1] Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. [2] These vaccines contrast to those produced by "killing" the pathogen ...
Pre-exposure prophylaxis (PrEP), is the use of medications to prevent the spread of disease in people who have not yet been exposed to a disease-causing agent.

[3] [4] Vaccines are categorised into conventional and next generation vaccines. [5] [6] Animal vaccines have been found to be the most cost effective and sustainable methods of controlling infectious veterinary diseases. [6] In 2017, the veterinary vaccine industry was valued at US$7 billion and it is predicted to reach US$9 billion in 2024. [7]
The International Vaccine Institute (IVI) is a non-profit, autonomous international organization established with the mandate of making vaccines available to all. . Collaborating closely with the global scientific community, public health entities, governments, and industry stakeholders, IVI focuses on vaccine research an
Also produced were anti-plague, anti-typhoid, anti-staphylococcal, anti-gonococcal, anti-colibacillairy, anti-streptococcal and anti-meningococcal vaccines, along with tetra-vaccines and various Besredka filtrates. The Institute also kept a reserve of 1 000 000 cc of anti-cholera vaccine to be used in the event of a cholera epidemic.
Tick-borne encephalitis vaccine is a vaccine used to prevent tick-borne encephalitis (TBE). [4] The disease is most common in Central and Eastern Europe, and Northern Asia. [4] More than 87% of people who receive the vaccine develop immunity. [5] It is not useful following the bite of an infected tick. [4] It is given by injection into a muscle ...
