Due to a rise in the number of reported flu cases and other respiratory viruses, Riley at IU Health is implementing visitor restrictions to protect patients and prevent further spreading. View full details.
Many common diseases and illnesses can be prevented by the use of vaccines. Most infants and young children in the U.S. no longer get sick from illnesses such as diphtheria or whooping cough because of immunizations. Yet these conditions still infect and even kill children in other countries. That is why vaccines are so important. Children can still be exposed to many preventable diseases simply by flying in an airplane or by visiting a foreign country.
Older children and teenagers must continue an immunization schedule to remain healthy. They may require boosters for some vaccine-preventable diseases. Older children are also susceptible to additional illnesses and require new immunizations.
The teenage years are a good time to catch up on any missed vaccinations such as the:
Children with certain health problems who are at high risk for serious disease may require extra vaccines to stay healthy, including the:
At Riley at IU Health, we follow the evidenced-based guidelines and recommendations for immunizations from the Centers for Disease Control and Prevention. Our doctors work with you to provide the vaccines your child needs at the right time to maintain optimal health.
Chickenpox (Varicella) Vaccine
Varicella is always present in the community and is highly contagious. Before the chickenpox vaccine became available in 1995, the virus had infected almost every adult in the United States. Chickenpox was responsible for an estimated 4 million illnesses, 11,000 hospitalizations and 100 deaths each year. Chickenpox is usually mild but may be severe. Complications such as bacterial infections, loss of fluids (dehydration), pneumonia and infections of the central nervous systems can occur. Furthermore, even after the chickenpox infection has healed, the inactivated virus remains in the body and can cause shingles. Shingles is a painful rash that occurs when the inactive virus living in a nerve becomes active. It affects about 300,000 people each year. Only people who have had chickenpox can get shingles.
Diphtheria, Tetanus, Acellular Pertussis (DTaP) Vaccine
Diphtheria is a serious bacterial infection that can lead to heart and nerve problems. The death rate is 5 percent to 10 percent, with higher rates (up to 20 percent) in infants. In the 1920s, diphtheria was a major cause of illness and death for children in the United States. Although diphtheria is now rare in the U.S., it is still a threat. Diphtheria is common in other parts of the world.
Tetanus is a severe, often fatal disease. The bacteria that cause tetanus are widely distributed in soil and street dust, are found in the waste of many animals and are resistant to heat and germ-killing cleaners. People who get tetanus suffer from stiffness and spasms of the muscles. The larynx (windpipe) can close, causing breathing difficulties. Muscle spasms can be so severe that they cause bone fractures. In extreme cases, people can become comatose and even die. Approximately 30 percent of people who develop tetanus die worldwide.
Pertussis (whooping cough) is most severe during the first year of life. Newborns with whooping cough may have apnea (stop breathing) and die. Even in older children, it can cause prolonged coughing spells that last for many weeks. These spells make eating, drinking and breathing difficult. When the coughing spells cause vomiting, infants lose weight and become dehydrated. Other complications of pertussis include pneumonia, seizures, infections of the central nervous system and rarely death.
Haemophilus Influenzae (Hib) Vaccine
Before the Hib vaccine became available in 1985, Haemophilus influenzae was the most common cause of bacterial meningitis in infants and children, affecting about 16,000 children in the United States each year. Prior to 1985, 1 in 20 children with Haemophilus meningitis died. Twenty percent to 30 percent of survivors were left with permanent brain damage.
Hepatitis B Vaccine
Hepatitis B is a serious liver disease caused by a virus. The hepatitis B virus is spread by contact with blood or other body fluids of an infected person. Hepatitis B can enter the bloodstream, attack the liver and cause severe illness and, in extreme cases, death. Infants and children who become infected with the hepatitis B virus are at the highest risk of developing lifelong infection, which often leads to death from liver disease and liver cancer. Approximately 25 percent of children who become infected with lifelong hepatitis B virus die of related liver disease as adults.
Influenza (Flu) Vaccine
Influenza is highly contagious and is carried in the air and by direct contact. Symptoms include fever, muscle pain, sore throat, cough and extreme fatigue. A complication of flu is pneumonia. Studies show that the flu vaccine reduces the risk of flu illness by between 50 percent and 60 percent among the overall population during seasons when most circulating flu viruses are like the vaccine viruses. During the flu seasons of 2010 to 2012, the flu vaccine reduced children’s risk of flu-related pediatric intensive care unit admissions by 74 percent. The flu vaccination also helps protect pregnant women and their babies for up to six months after birth. Giving the flu vaccine to pregnant women is 92 percent effective in preventing hospitalization of infants for flu. The flu vaccine is believed to have prevented 67,000 flu-related hospitalizations in the 2014-2015 season, during which 40 million people contracted the flu.
Measles, Mumps, Rubella (MMR) Vaccine
Before the measles vaccine was available, nearly everyone in the United States got measles (seven-day measles). There were approximately 3 million to 4 million cases each year. As many as 20 percent of people with measles required hospitalization, and almost 10 percent suffered complications such as diarrhea, ear infections and pneumonia. When the virus infects the brain, permanent damage to brain function occurs. Measles is one of the most infectious diseases in the world. More than 90 percent of people who are not immune will develop measles if they are exposed to the virus. In 1998, most cases of measles were associated with international visitors or United States residents who were exposed to the measles virus while traveling abroad. With more parents refusing immunizations for their children, there is an increase in measles cases in the U.S.
Before the mumps vaccine was introduced, mumps caused deafness in about 1 in every 20,000 reported cases in children. Mumps is usually a mild viral disease. However, rare conditions, such as swelling of the brain, nerves and spinal cord, can lead to serious side effects such as paralysis and seizures. Serious side effects of mumps are more common in adults than in children. Swelling of the testes is the most common side effect in males past the age of puberty, occurring in up to 20 percent to 50 percent of men who become ill with mumps. An increase in miscarriage has been found among women who develop mumps in the first three months of their pregnancy.
Rubella (German measles or three-day measles) is usually mild in children and adults, but up to 90 percent of infants born to mothers who become infected with rubella in the first three months of pregnancy will develop congenital rubella syndrome, resulting in heart defects, cataracts, mental retardation and deafness.
Pneumococcal infections include ear infections, sinusitis, pneumonia and meningitis. All of these diseases can have serious complications, such as respiratory failure and bacteria in the blood. Pneumococcal disease kills about 40,000 people in the world each year.
Inactivated Poliovirus Vaccine (IPV)
Poliovirus can cause minor infections that heal after a few days, or it can cause rapidly progressive, serious infections that are complicated by paralysis, permanent physical disability and even death. Before the polio vaccine was available in the United States, 13,000 to 20,000 cases of paralytic polio occurred each year. These annual epidemics left thousands of victims—mostly children—in braces, crutches and wheelchairs for life.
Rotavirus spreads by the mouth and is most often contracted by infants and young children. It causes inflammation of the stomach and intestines (gastroenteritis). This leads to diarrhea, fever, vomiting and abdominal pain. The diarrhea can be severe and can cause dehydration. The rotavirus vaccine was introduced in 2006. In 2008, rotavirus caused an estimated 453,000 deaths worldwide in children younger than 5 years of age. Each year, the vaccine prevents an estimated 40,000 to 50,000 hospitalizations among U.S. infants and young children.
Hepatitis A Vaccine
Hepatitis A is an infection in the liver caused by the hepatitis A virus. The virus spreads from person to person orally from contact with objects, food or drinks contaminated by the feces (stool) of an infected person. Symptoms include fever, fatigue, loss of appetite, nausea, abdominal discomfort, dark urine and jaundice (yellowing of the skin and eyes). An infected person may have no symptoms, may have mild illness for a week or two or may have severe illness for several months that requires hospitalization. About 100 people in the U.S. die from hepatitis A each year.
Human Papillomavirus (HPV) Vaccine
Human papillomavirus is a common virus. HPV is most common in people in their teens and early 20s. It is the major cause of cervical cancer in women and genital warts in women and men. The strains of HPV that cause cervical cancer and genital warts are spread during sex. The vaccine is recommended for boys and girls. Every year, about 17,600 women and 9,300 men are affected by cancers caused by HPV. For HPV vaccines to be effective, they should be given before sexual activity begins. There is no reason to wait until a teen is having sex to offer HPV vaccination. Preteens should receive all three doses of the HPV vaccine series long before they begin any type of sexual activity and are exposed to HPV. The HPV vaccine produces a higher immune response in preteens than it does in older teens and young women.
Meningococcal Conjugate Vaccine (MCV4)
Meningococcal disease is caused by bacteria and is a leading cause of bacterial meningitis (infection around the brain and spinal cord). The bacteria are spread through the exchange of nose and throat droplets, such as when coughing, sneezing or kissing. Symptoms include nausea, vomiting, sensitivity to light, confusion and sleepiness. Meningococcal disease also causes blood infections. About 1 in every 10 people who get the disease dies from it. Survivors of meningococcal disease may lose their arms or legs, become deaf, have hearing or vision loss, become developmentally disabled or suffer seizures or strokes. The disease is most common in infants and adolescents between the ages of 16 and 23. In 2013, there were 550 reported cases in the U.S.
Serogroup B Meningococcal (MenB) Vaccine
There are different serogroups of bacteria that cause meningococcal disease. Serogroup B is one of five groups that cause most infections. Meningococcal disease causes meningitis and infections of the blood (bacteremia or septicemia). It can easily spread among people who live together, such as college students living in a dorm, by sharing food and utensils, coughing, sneezing and kissing. Even when treated, meningococcal disease kills 10 to 15 infected people out of 100. Among those who recover, about 10 to 20 out of every 100 will suffer disabilities such as hearing loss, brain damage, amputations, speech loss and vision loss or severe scars from skin grafts.
