Typhoid vaccines are vaccines that prevent typhoid fever. [1] [2] [3] Several types are widely available: typhoid conjugate vaccine (TCV), Ty21a (a live oral vaccine) and Vi capsular polysaccharide vaccine (ViPS) (an injectable subunit vaccine). They are about 30 to 70% effective in the first two years, depending on the specific vaccine in ...

During the American Civil War, 81,360 Union soldiers died of typhoid or dysentery, far more than died of battle wounds. [25] In the late 19th century, the typhoid fever mortality rate in Chicago averaged 65 per 100,000 people a year. The worst year was 1891, when the typhoid death rate was 174 per 100,000 people. [26]
Typhoid is treated with antibiotics such as azithromycin, fluoroquinolones, or third-generation cephalosporins. [2] Resistance to these antibiotics has been developing, which has made treatment more difficult. [2] [14] [15] In 2015, 12.5 million new typhoid cases were reported. [16] The disease is most common in India. [2] Children are most ...
Ty21a is a live attenuated bacterial vaccine that protects against typhoid.First licensed in Europe in 1983 and in the United States in 1989, it is an orally administered, live-attenuated Ty2 strain of S. Typhi in which multiple genes, including the genes responsible for the production of Vi, have been deleted so as to render it harmless but nevertheless immunogenic.
The Vi capsular polysaccharide vaccine (or ViCPS) is a typhoid vaccine recommended by the World Health Organization for the prevention of typhoid (another is Ty21a).The vaccine was first licensed in the US in 1994 and is made from the purified Vi capsular polysaccharide from the Ty2 Salmonella Typhi strain; it is a subunit vaccine.
Little research exists on how much this condition affects Indian people's work, leisure, and sleep.
