Influenza (flu) - The flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent seasonal flu is by getting a seasonal flu vaccination each year.

MMR - The MMR vaccine is a "three-in-one" vaccine that protects against measles, mumps and rubella.

Measles - is a highly infectious respiratory disease that can result in severe, sometimes permanent, complications including pneumonia, seizures, brain damage and death.

Mumps - is caused by the mumps virus, which lives and reproduces in the upper respiratory tract. Mumps can lead to serious complications such as deafness, meningitis (infection of the brain and spinal cord covering), painful swelling of the testicles or ovaries, and, rarely, death.

Rubella - also known as German measles, is a viral disease spread by contact with an infected person through coughing and sneezing. The main concern with rubella is infection in pregnant women. There is at least a 20 percent chance of damage to the fetus if a woman is infected with rubella early in pregnancy.

Hepatitis B - Hepatitis B is a serious liver disease caused by the hepatitis B virus (HBV). It can often be a “silent disease” that affects people without making them feel sick. Chronic hepatitis B disease can result in long-term health problems, and even death.

Human Papillomavirus - Human papillomavirus (HPV) is a group of more than 100 viruses that are usually spread through sexual contact. The most serious long-term complication of HPV infection is cervical cancer.

Varicella - Chickenpox is caused by the highly contagious varicella zoster virus and results in a skin rash of blister-like lesions, covering the body but usually more concentrated on the face, scalp and trunk. Most, but not all, infected individuals have fever, which develops just before or when the rash appears.

Meningitis - Meningitis is an inflammation of the membranes that cover the brain and spinal cord. People sometimes refer to it as spinal meningitis. Meningitis is usually caused by a viral or bacterial infection.  Viral meningitis is generally less severe and clears up without specific treatment. But bacterial meningitis can be quite severe and may result in brain damage, hearing loss, or learning disabilities.  High fever, headache, and stiff neck are common symptoms of meningitis in anyone over the age of two years. These symptoms can develop over several hours, or they may take one to two days. Other symptoms may include nausea, vomiting, discomfort looking into bright lights, confusion, and sleepiness.

 Pneumococcus - Pneumococcal disease is an infection caused by a type of bacteria called Streptococcus pneumoniae (pneumococcus). There are different types of pneumococcal disease, such as pneumococcal pneumonia, bacteremia, meningitis and otitis media. Pneumococcus is in many people's noses and throats and is spread by coughing, sneezing or contact with respiratory secretions.  Pneumococcal disease can be fatal. In some cases, it can result in long-term problems, like brain damage, hearing loss, and limb loss.

Hepatitis A - Hepatitis A is a contagious liver disease caused by the hepatitis A virus (HAV). The infection is most often spread by the fecal-oral route. It can also be spread by close person-to-person contact such as household or sexual contact with an infected person. The virus is also spread by eating contaminated food or drinking contaminated water. Hepatitis A is the most common vaccine-preventable disease acquired during travel.

Poliomyelitis (polio) – Polio is a highly infectious disease caused by a virus that invades the nervous system.  Up to 95 percent of persons infected will have no symptoms.  One percent of polio cases result in permanent paralysis of the limbs (usually the legs).  Of those paralyzed, 5-10 percent die when paralysis strikes the respiratory muscles.
