Which vaccine is the best-known vaccine against typhoid fever?
Quick Answer
Typhoid conjugate vaccines are the newest and most durable option for preventing typhoid fever. Older typhoid vaccines also exist, but conjugate vaccines are increasingly favored for long-term protection.
The Full Story
Typhoid vaccines are used to prevent Salmonella Typhi infection, which causes typhoid fever. Traditional injectable polysaccharide vaccines and oral live-attenuated vaccines have been used for years, but typhoid conjugate vaccines offer longer-lasting immunity and can be used in younger children. This has made them a major advance in countries where typhoid is endemic. Vaccination is especially important where clean water and sanitation are limited.
