Vivotif

Vivotif is a live, attenuated oral vaccine for typhoid fever prevention. It contains Salmonella Typhi, Strain Ty21a, offering protection before travel or exposure. This vaccine is taken as capsules and is suitable for adults and children over 6 years. Store in a cool, dry place away from direct sunlight.

Vivotif is used to help prevent typhoid fever, a serious infection caused by the Salmonella Typhi bacteria. It is recommended for travelers to areas where typhoid is common, as well as for household contacts of typhoid carriers. The vaccine works by stimulating the body’s immune system to produce antibodies against the bacteria. It does not treat active infections but helps reduce the risk of illness.

After taking Vivotif, some people may experience mild effects such as stomach upset, nausea, or a slight fever. These effects are usually temporary and resolve on their own. The vaccine is designed to be well-tolerated, with most users experiencing no significant discomfort. It is important to complete the full vaccination course for optimal protection.

Vivotif should not be used by individuals with weakened immune systems or those undergoing immunosuppressive therapy. People with acute febrile illness should delay vaccination until recovered. It is not recommended for children under 6 years of age. Always inform your healthcare provider about any allergies or medical conditions before vaccination.

Vivotif may interact with antibiotics or other medications that weaken the immune system, potentially reducing its effectiveness. Avoid taking antimalarial drugs like chloroquine or mefloquine within 3 days before or after vaccination, as they may interfere with the immune response. Live vaccines should not be given close to each other unless specified by a healthcare professional.
