Meningitis
Meningitis is an infection and inflammation of the fluid and three membranes (meninges) protecting your brain and spinal cord. The tough outer membrane is called the dura mater, and the delicate inner layer is the pia mater. The middle layer is the arachnoid, a web-like structure containing the fluid and blood vessels covering the surface of the brain.
DTAP
Diphtheria, tetanus, and acellular pertussis vaccine (also known as DTaP) is a combination immunizing agent given by injection to protect against infections caused by diphtheria, tetanus (lockjaw), and pertussis (whooping cough). This vaccine is given only to children 6 weeks through 6 years of age (before the child's 7th birthday).
Diphtheria is a serious illness that can cause breathing difficulties, heart problems, nerve damage, pneumonia, and possibly death. The risk of serious complications and death is greater in very young children and in the elderly.
Tetanus (also known as lockjaw) is a serious illness that causes convulsions (seizures) and severe muscle spasms that can be strong enough to cause bone fractures of the spine. Tetanus causes death in 30 to 40 percent of cases.
Pertussis (also known as whooping cough) is a serious disease that causes severe spells of coughing that can interfere with breathing. Pertussis also can cause pneumonia, long-lasting bronchitis, seizures, brain damage, and death.
Diphtheria, tetanus, and pertussis are serious diseases that can cause life-threatening illnesses. Although some serious side effects can occur after a dose of DTaP (usually from the pertussis vaccine part), this rarely happens. The chance of your child catching one of these diseases, and being permanently injured or dying as a result, is much greater than the chance of your child getting a serious side effect from the DTaP vaccine.
This vaccine is to be administered only by or under the supervision of your child's doctor or other health care professional.
Varicella
Varicella virus vaccine is an active immunizing agent that is given to protect against infection caused by the varicella-zoster virus (VZV). The vaccine works by causing the body to produce its own protection (antibodies) against the virus.
Varicella (commonly known as chickenpox) is an infection that is easily spread from one person to another. Chickenpox is usually a mild infection but sometimes it can cause serious problems, such as pneumonia, inflammation of the brain, and a rare disease called Reye's syndrome.
Hepatitis C
Hepatitis C is an infection caused by a virus that attacks the liver and leads to inflammation. Most people infected with the hepatitis C virus (HCV) have no symptoms. In fact, most people don't know they have the hepatitis C infection until liver damage shows up, decades later, during routine medical tests.
Hepatitis C is one of several hepatitis viruses and is generally considered to be among the most serious of these viruses. Hepatitis C is passed through contact with contaminated blood — most commonly through needles shared during illegal drug use.
Tetanus
Tetanus is a serious bacterial disease that affects your nervous system, leading to painful muscle contractions, particularly of your jaw and neck muscles. Tetanus can interfere with your ability to breathe and, ultimately, threaten your life. Tetanus is commonly known as "lockjaw."
Thanks to the tetanus vaccine, cases of tetanus are rare in the United States and the developed world. The incidence of tetanus is much higher in less developed countries. Around a million cases occur worldwide each year.
