What is the varicella vaccine, and who should receive it?

Varicella is the virus that causes chickenpox. While the disease is usually self-limited, it can cause death and permanent injury. The groups at greatest risk are infants, people over 15 years of age, and immunocompromised people. The vaccine came out in the mid-1990s and unfortunately does not offer complete protection, but even those who get the disease after vaccination have a milder form of the condition. Prior to use of the vaccine, hundreds of children died every year from chickenpox. It is recommended that all adolescents and adults without documented evidence of chickenpox or previous vaccination receive the two-dose series. For specific guidance, please refer to Table 4 for adolescents or Tables 5A-5D for adults.

What is the pneumococcal vaccine, and who should receive it?

Streptococcus pneumoniae (also called pneumococcus) is a bacterium that can cause severe illness, including meningitis and pneumonia. The vaccine is routinely given to children; however, it is only given to adolescents and adults who are at higher risk. Elderly adults are one group that is considered at higher risk, and it is recommended that all adults receive one dose of the vaccine after 65 years of age. For specific guidance and a list of higher risk groups, please refer to Table 4 for adolescents or Tables 5A-5D for adults.

What is the influenza vaccine, and who should receive it?

Influenza (flu) is an acute viral illness that can kill even healthy people. Unfortunately, the influenza virus changes a little each year, and scientists have to make educated guesses about which forms of the virus will be infecting people and circulating each year. Based on the best available evidence, they create a vaccine each year containing three of the likely influenza virus types.

There are two types of vaccine: a live attenuated vaccine (nasal spray) and an inactivated vaccine (shot). You cannot get the flu from getting the flu shot because it has inactivated virus (killed virus with heat or chemicals). The immunity from the vaccines is limited, and vaccinations must be repeated yearly. In August 2008, the Advisory Committee on Immunization Practices changed the recommendation on adolescents. It is now recommended that all people between 6 months and 18 years of age receive an annual vaccination. Although the CDC encourages that any adult who wants to decrease the chance of getting the flu get the influenza vaccine, certain high-risk groups are recommended to always get the annual flu vaccine (Table 5C). Adults over 50 years of age are considered to be at high risk and should receive the yearly influenza vaccination. For specific guidance and a list of higher-risk groups, please refer to Table 4 for adolescents or Tables 5A-5D for adults.

  • Related Diseases & Conditions

    • Pneumonia
      • Pneumonia is inflammation of one or both lungs with consolidation. Pneumonia is frequently but not always due to infection. The infection may be bacterial, viral, fungal or parasitic. Symptoms may include fever, chills, cough with sputum production, chest pain, and shortness of breath.
    • Shingles
      • Shingles (herpes zoster) is a skin rash caused by the same virus that causes chickenpox. Under certain circumstances, such as emotional stress, immune deficiency, or with cancer, the virus re-activates causing shingles. Shingles are catching and can spread from an infected person to others who have not had chickenpox. There are a variety of treatments for shingles.
    • Hepatitis B
      • The hepatitis B virus is a unique, coated DNA virus belonging to the Hepadnaviridae family of viruses. The course of the virus is determined primarily by the age at which the infection is acquired and the interaction between the virus and the body's immune system. Successful treatment is associated with a reduction in liver injury and fibrosis (scarring), a decreased likelihood of developing cirrhosis and its complications, including liver cancer, and a prolonged survival.
    • Whooping Cough (Pertussis)
      • Whooping cough (pertussis) is highly contagious respiratory infection that is caused by the bacteria Bordetella pertussis. There are an estimated 300,000 plus deaths annually from whooping cough (pertussis). Whopping cough commonly affects infants and young children, but can be prevented with immunization with the vaccine. First stage whooping cough symptoms are a runny nose, sneezing, low-grade fever, a mild cough with the cough gradually becoming more severe. After one to two weeks, the second stage of whooping cough begins.
    • Genital Warts (HPV)
      • Human papillomavirus (HPV) infection is the most common sexually transmitted infection in the U.S. HPV is primarily transmitted by sexual contact. While some people develop warts in the genital region after infection, others experience no symptoms. Though genital warts can be removed, there is no cure for HPV infection. There is a vaccine to prevent infection from four common HPV types.
    • Flu (Influenza)
      • Influenza (flu) is a respiratory illness caused by a virus. Flu symptoms include fever, cough, sore throat, runny nose, headache, fatigue, and muscle aches. The flu may be prevented with an annual influenza vaccination.
    • Chickenpox (Varicella)
      • Chickenpox (chicken pox) is a contagious childhood disease caused by the varicella-zoster virus. Symptoms have an incubation period of 14 to 16 days and include a couple days of mild fever, weakness, and red, raised rash that progresses to blisters that eventually burst and crust over. Complications include bacterial infection of the open sores, scarring, encephalitis, nerve palsies, and Reye's syndrome.
    • Measles
      • Measles (rubeola) is a highly contagious disease that's caused by a virus. Symptoms include a rash, high fever, cough, runny nose, and red eyes. Treatment focuses on symptom relief. The disease can be prevented with the measles, mumps, and rubella vaccine.
    • Rabies
      • Rabies is a potentially fatal viral infection. Rabies symptoms include fever, headache, myalgia, and can progress to more serious symptoms such as seizures, coma and death. The rabies vaccine (rabies treatment) should be administered immediately after the person or pet has been bitten.
    • Mercury Poisoning
      • Mercury is a naturally occurring element found in water, soil, and the air. Mercury is also contained in some fish, some of the products we use in the home, school, or dentist. Information about sources of mercury exposure, potential health effects, symptoms of exposure, fish that may contain mercury, consumer products that contain mercury, and ways to reduce your exposure to mercury is important for the health of you, and your family.
    • Mumps
      • Mumps is an acute viral illness caused by the mumps virus. Symptoms of mumps include fever, headache, muscle aches, tiredness, and loss of appetite; followed by swelling of the salivary glands.
    • Tetanus
      • Tetanus is an often-fatal disease caused by nerve toxins produced by the common bacteria Clostridium tetani. In a seven-day period after infection, a person experiences muscle spasms, restlessness, headache, irritability, then lockjaw, and the lungs stop functioning. Tetanus is treatable with antibiotics and drainage. Sedation is often give to stop muscle spasms.
    • Meningitis
      • Encephalitis is a brain inflammation that causes sudden fever, vomiting, headache, light sensitivity, stiff neck and back, drowsiness, and irritability. Meningitis is an infection that causes inflammation of the meninges that surround the brain and spinal cord. Symptoms of meningitis include high fever, headache, nausea, vomiting, and stiff neck.
    • Diphtheria
      • Diphtheria is an infectious disease caused by the Corynebacterium diphtheriae bacteria. The disease is transmitted via contact with airborne droplets or direct contact with skin lesions. Symptoms and signs include fever, sore throat, hoarseness, difficulty swallowing and breathing. Antibiotics and the diphtheria antitoxin are used in the treatment of diphtheria.
    • Bronchiectasis
      • Bronchiectasis is a condition in which the bronchial tubes of the lung become damaged. Inflammation from infection or other causes destroys the smooth muscles of the bronchial tubes. Bronchiectasis is a form of COPD (which includes emphysema and chronic bronchitis). There are three primary types of bronchiectasis: 1) cylindrical bronchiectasis; 2) saccular bronchiectasis; and 3) cystic bronchiectasis. Bronchiectasis may also be acquired or congenital. The most common symptoms of bronchiectasis are recurrent cough and sputum production. There is no cure for bronchiectasis. Treatment is often geared toward controlling the symptoms of bronchiectasis.
    • Travel Medicine
      • Travelers should prepare for their trip by visiting their physician to get the proper vaccinations and obtain the necessary medication if they have a medical condition or chronic disease. Diseases that travelers may pick up from contaminated water or food, insect or animal bites, or from other people include malaria, meningococcal meningitis, yellow fever, hepatitis A, typhoid fever, polio, and cholera.
    • Hepatitis A
      • Hepatitis means inflammation of the liver. Hepatitis A is one type of liver disease caused by a virus. Since hepatitis A is a virus, it can pass from person to person from eating or drinking contaminated food or coming into contact with contaminated materials containing the virus. Symptoms of hepatitis A include stomach pain, diarrhea, dark yellow urine, jaundice, and more. There is a vaccine to prevent contracting hepatitis A.
    • German Measles (Rubella)
      • German measles is a disease that's caused by a virus. Symptoms include rash and fever for two to three days. The MMR (measles, mumps, and rubella) vaccine prevents this disease.
    • Hepatitis A and B Immunizations
      • Hepatitis A and hepatitis B are the two most commnon viruses that infect the liver. Hepatitis A and Hepatitis B can be prevented and treated with immunizations (vaccinations) such as Havrix, Vaqta, Twinrix, Comvax, Pediarix, and hepatitis b immune globulin (HBIG).
    • Meningococcemia
      • Meningococcemia is a bloodstream infection caused by Neisseria meningitides. Meningococcemia symptoms include fever, headache, fatigue, and body aches. Meningococcemia is treated with intravenous antibiotics. There is an effective and safe vaccine to protect against most serogroups of meningococcus that cause meningococcemia.
    • Children's Health
      • Children's health is focused on the well-being of children from conception through adolescence. There are many aspects of children's health, including growth and development, illnesses, injuries, behavior, mental illness, family health and community health.
    • Pregnancy and Drugs (Prescription and OTC)
      • Taking prescription medications or over-the-counter drugs or supplements should be discussed with your doctor. There are some medications that have been found to cause no problems in pregnancy, however, medications such as Accutane for acne, should never be taken during pregnancy.
