What is Vivotif (oral typhoid vaccine) and how is it taken?
Vivotif is an oral, live-attenuated typhoid vaccine taken by mouth to help prevent typhoid fever. It is used as a vaccine series (not a single-dose shot), and the doses must be taken on schedule for best protection. After finishing the series, protection builds over time rather than immediately.
Who is Vivotif for?
Vivotif is intended for people who are at risk of exposure to typhoid fever, such as travelers to areas where typhoid is common. It’s typically considered for children and adults who meet the vaccine’s age/indication guidance and can follow the oral dosing schedule.
How soon does Vivotif start working?
Protection develops after you complete the vaccine series. The exact timing depends on completing the full set of doses as directed, because the immune response relies on the sequence rather than one dose alone.
What side effects do people report from Vivotif?
Common side effects for oral vaccines can include mild gastrointestinal symptoms (such as nausea or stomach discomfort) and headache. Because Vivotif is a live-attenuated vaccine, people with certain immune system conditions or who are immunocompromised may need to avoid it unless a clinician specifically advises it.
What should you avoid around the dosing days?
Oral typhoid vaccines depend on taking the capsules correctly and completing the schedule. People may be advised to follow specific instructions around taking the capsules (for example, taking them with cool/room-temperature liquids rather than hot liquids, and adhering to timing), since temperature and administration details can affect live vaccine viability.
How effective is Vivotif compared with typhoid shots?
Vivotif is one option for typhoid prevention, alongside injected typhoid vaccines. Effectiveness can vary by vaccine type, the circulating strain in the destination region, and time since vaccination. People choosing between oral and injectable options usually base the decision on practicality (oral series vs. injection), age eligibility, and travel plans.
Can you get it if you’re pregnant or immunocompromised?
Because Vivotif is live-attenuated, clinicians often pay extra attention for people who are pregnant, immunocompromised, or taking immunosuppressive medications. The safe choice depends on individual risk of exposure and medical circumstances, so it should be decided with a healthcare professional.
How much does Vivotif cost?
Pricing depends on country, pharmacy, insurance coverage, and whether you buy the full vaccine series.
