Typhoid vaccine: Who needs it, vaccination schedule, and how it works

A clear guide to the typhoid vaccine in India: what it protects against, who should get it, how the schedule works, and how to get vaccinated at home.

The typhoid vaccine stimulates an immune response against Salmonella Typhi, the bacterium responsible for typhoid fever, providing protection through a single-dose injectable conjugate formulation that is recommended for adults and children in endemic regions, travellers to high-risk areas, and individuals with ongoing exposure risk through food, water, or occupational contact.

Typhoid fever is still very much a present-day concern in India, not a historical one. It spreads through contaminated food and water, which means the risk is tied directly to everyday life rather than unusual circumstances. Most people who get it didn't do anything wrong. They ate at a place with questionable hygiene, drank unsafe water, or came into contact with someone who was infected. A vaccine that takes one injection and takes that risk off the table is, by most measures, one of the simpler preventive decisions an adult can make.

This guide covers how the typhoid vaccine works, who needs it, what the schedule looks like, and how to get vaccinated at home through Apollo Homecare.

What is typhoid and why does the vaccine matter?

Typhoid fever is a serious bacterial infection caused by Salmonella Typhi. It typically begins with a high fever, weakness, and stomach pain, and if not treated promptly can progress to severe complications including intestinal perforation. It spreads through food and water contaminated by the faeces of an infected person, making it particularly prevalent in areas where sanitation and hygiene are inconsistent.

India remains one of the countries with the highest burden of typhoid globally. Urban and semi-urban areas with variable water quality and food safety standards carry ongoing risk for residents and travellers alike. The vaccine doesn't eliminate the need for safe food and water practices, but it provides a meaningful layer of protection that those practices alone cannot guarantee.

According to a Cochrane systematic review published on PubMed, typhoid vaccines are estimated to be 50 to 85% effective depending on the type used, with the typhoid conjugate vaccine offering stronger and more durable protection than older formulations.

How does the typhoid vaccine work?

The typhoid conjugate vaccine (Typbar-TCV) works by introducing a component of the Salmonella Typhi bacterium to the immune system in a way that triggers an immune response without causing infection. The immune system learns to recognise and fight the bacterium. If the person is later exposed to Salmonella Typhi, the immune system responds faster and more effectively than it would in an unvaccinated individual.

The conjugate formulation links the bacterial antigen to a carrier protein, which produces a stronger and longer-lasting immune response than older polysaccharide vaccines. This makes it the preferred typhoid vaccine for adults and children above six months of age.

Who needs the typhoid vaccine?

1. Adults and children living in or travelling to endemic areas: Anyone living in or visiting regions with higher rates of typhoid, including most of India, should consider vaccination as part of routine preventive health.

2. Travellers to high-risk regions: Adults travelling internationally to South Asia, Southeast Asia, sub-Saharan Africa, or other areas with high typhoid burden are specifically recommended to get vaccinated before departure.

3. People with frequent exposure to contaminated food or water: Those whose work or living conditions involve regular contact with environments where food and water safety cannot be guaranteed.

4. Household contacts of typhoid carriers: People living with a confirmed or chronic typhoid carrier are at elevated risk and should be vaccinated.

5. Healthcare and laboratory workers: Those who handle Salmonella Typhi specimens or work in settings with higher exposure risk.

What is the typhoid vaccine schedule in India?

The typhoid conjugate vaccine (Typbar-TCV) is administered as a single dose by injection. For most adults and children, one dose is sufficient to provide protection. A booster dose is recommended every three years for individuals who remain at ongoing risk, such as frequent travellers or those living in high-endemic areas.

The vaccine can be given to individuals from six months of age onward. There is no upper age limit for vaccination.

How long does typhoid vaccine protection last?

The typhoid conjugate vaccine provides protection for approximately three years. After this period, a booster dose is recommended for anyone who continues to be at risk. Speak with a doctor or Apollo Homecare's care coordination team to determine whether a booster is due based on your vaccination history and current risk profile.

Can the typhoid vaccine be taken at home?

Yes. Apollo Homecare's typhoid vaccination-at-home service brings a trained healthcare professional to your residence to administer the Typbar-TCV vaccine. The vaccine is transported under cold-chain conditions, administered using sterile single-use equipment, and post-vaccination guidance is provided before the visit ends.

This is particularly convenient for families with children, adults with busy schedules, or anyone who prefers not to visit a clinic for a routine vaccination. For a complete overview of vaccines available at home, read our guide: Vaccination at home: how it works, benefits, and how to book.

Are there side effects of the typhoid vaccine?

The typhoid vaccine is well tolerated by most people. Common side effects are mild and localised to the injection site: soreness, redness, or mild swelling that typically resolves within a day or two. Some people experience temporary fatigue or a mild headache after vaccination. These are normal immune responses and are not a cause for concern.

Severe allergic reactions are rare. If you experience difficulty breathing, facial swelling, or a rapid heartbeat following vaccination, seek medical attention immediately.

Inform the healthcare professional before vaccination if you are currently unwell with a fever, are pregnant, or have a known allergy to any vaccine component.

Conclusion

Typhoid is preventable. For anyone living in India, travelling to high-risk regions, or with regular exposure to environments where food and water safety is variable, the typhoid vaccine is a straightforward and highly practical step in preventive health. One injection, protection for three years, and it can now be done at home without a clinic visit.
