Specific Vaccine Information
- Typhoid – Typhoid, a bacterial infection, is primarily transmitted through contaminated food, water, or direct contact with infected people. Vaccination is a key preventive measure, recommended for travellers to endemic regions and those at risk due to occupation.
- Hepatitis A – Hepatitis A spreads through contaminated food, water, and close contact. Protect yourself by getting vaccinated with the hepatitis A vaccine and maintaining proper hygiene. Vaccination is a critical step in preventing this contagious liver infection, according to health authorities.
- Rabies – Preventing rabies involves avoiding contact with infected animals and ensuring timely vaccination. The rabies vaccine is a critical tool, offering protection through post-exposure prophylaxis (PEP) and preemptive vaccination for high-risk individuals like travellers.
- Hepatitis B – The hepatitis B virus causes liver infection, spreading through contact with infected bodily fluids. Prevention measures include safe practices and, notably, hepatitis B vaccination. This vaccine effectively triggers the immune system to produce antibodies, offering reliable, long-term protection against the virus.
- Measles, Mumps, Rubella (MMR) – Measles, mumps, and rubella are contagious diseases transmitted via respiratory droplets and touch. Preventing these illnesses is primarily achieved through vaccination, using the MMR vaccine. It’s administered in two doses and provides immunity against all three viruses.
Dengue is present on Guam. Be sure to bring and use insect repellent. Netting may also be recommended.
