Specific Vaccine Information
- Typhoid – Typhoid fever, a bacterial infection caused by Salmonella Typhi, spreads through contaminated food and water sources. Vaccination is recommended for travelers and those at risk, along with maintaining good hygiene and food safety.
- Hepatitis A – Hepatitis A is a contagious liver infection transmitted through contaminated food, water, or close personal contact. To prevent it, practicing good hygiene and getting vaccinated with the hepatitis A vaccine are crucial steps recommended by the CDC.
- Chikungunya – Chikungunya, a viral disease transmitted by mosquitoes, can be prevented by minimizing mosquito exposure and eliminating breeding sites. Vaccination is considered the best form of protection.
- Hepatitis B – The hepatitis B virus leads to liver infection through contact with infected fluids. The most effective safeguard is the hepatitis B vaccine, administered in a series of shots that stimulate the body to produce antibodies, providing long-term immunity. It is crucial for infants and those at an increased risk of exposure.
- Measles, Mumps, Rubella (MMR) – Measles, mumps, and rubella are contagious viral infections, causing various symptoms and complications. To prevent them, vaccination is key. The MMR vaccine, given in two doses, safeguards against all three diseases and helps establish herd immunity, reducing the risk of outbreaks.
