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 ...
Typhoid fever, also known simply as typhoid, is a disease caused by Salmonella enterica serotype Typhi bacteria, also called Salmonella Typhi. [2] [3] Symptoms vary from mild to severe, and usually begin six to 30 days after exposure. [4] [5] Often there is a gradual onset of a high fever over several days. [4]
Typhoid fever is caused by the bacterium Salmonella enterica Serovar Typhi. [37] In Canada alone, the typhus epidemic of 1847 killed more than 20,000 people from 1847 to 1848, mainly Irish immigrants in fever sheds and other forms of quarantine, who had contracted the disease aboard the crowded coffin ships in fleeing the Great Irish Famine ...
Salmonellosis is a symptomatic infection caused by bacteria of the Salmonella type. [1] It is the most common disease to be known as food poisoning (though the name refers to food-borne illness in general), these are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food.
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.
In 2000, typhoid fever caused an estimated 21.7 million illnesses and 217,000 deaths. [1] It occurs most often in children and young adults between 5 and 19 years old. [2] In 2013, it resulted in about 161,000 deaths – down from 181,000 in 1990. [3]
The chlorination of public drinking water led to the sharp reduction of typhoid in developed nations. [8] In typhoid-endemic countries, Typhoid vaccines have been shown to prevent 40 to 90% of cases during the first two years, [ 9 ] and may have some effect for up to seven years.
