The oral typhoid vaccine contains live attenuated (weakened) bacteria. When taken as directed, it helps the body build immunity by stimulating an immune response, providing protection against future infections.

The oral vaccine is taken as a series of four capsules. One capsule is taken every other day (e.g., Day 1, Day 3, Day 5, and Day 7) with a cold or lukewarm drink, one hour before a meal. It's important to complete the entire series to ensure effective protection.

The oral typhoid vaccine typically provides protection for up to five years. After this period, a booster dose may be recommended if you continue to travel to areas where typhoid fever is common.

Common side effects may include mild gastrointestinal symptoms such as nausea, stomach pain, or diarrhea. Some people may also experience a low-grade fever. These side effects are usually temporary and resolve on their own. If you experience severe or persistent side effects, contact your healthcare provider.

Refrigeration is required for the oral typhoid vaccine to maintain its potency and effectiveness. It will be shipped and stored refrigerated between 35.6°F–46.6°F, which requires specialized packaging. The live attenuated bacteria in the capsules need to be kept at a stable, cold temperature to ensure they remain viable and capable of stimulating an immune response. Failure to store the vaccine properly can reduce its efficacy and compromise the protection it provides. Always follow storage instructions and keep the vaccine refrigerated until use.

Vivotif is generally recommended for individuals aged six years and older who are traveling to areas where typhoid fever is common. However, it may not be suitable for individuals with certain medical conditions or weakened immune systems. Consult with your healthcare provider to determine if the oral typhoid vaccine is appropriate for you.

Yes, it is important to continue practicing good hygiene and food safety measures even after receiving the oral typhoid vaccine. This includes drinking bottled or boiled water, avoiding raw or undercooked foods, and washing your hands frequently. The vaccine provides significant protection, but no vaccine is 100% effective.

The safety of the oral typhoid vaccine in pregnant or breastfeeding women has not been fully established. If you are pregnant or breastfeeding, it is important to discuss the risks and benefits with your healthcare provider before taking the vaccine.

The main differences between the oral typhoid vaccine and the injectable typhoid vaccine are their forms, administration methods, and duration of protection. The oral vaccine comes in the form of capsules containing live attenuated (weakened) bacteria, taken over a series of four doses. It stimulates immunity through the digestive system and typically provides protection for up to five years. The injectable typhoid vaccine, on the other hand, is administered as a single intramuscular injection containing inactivated (killed) bacteria. It usually provides protection for about two years. Both vaccines are effective, but the choice between them may depend on personal preference, medical history, and travel plans. It's best to consult with a healthcare provider to determine which vaccine is most suitable for you.

Yes, typhoid fever is highly contagious. It is primarily spread through the ingestion of food or water contaminated with the feces of an infected person. This is more common in areas with poor sanitation and limited access to clean water. Typhoid can also be spread through direct contact with an infected person. Practicing good hygiene, such as regular handwashing and consuming safe, clean food and water, can help prevent the spread of typhoid.
