Why do I need vaccines?

Vaccines protect you from serious and life-threatening diseases. As you get older, some of the vaccinations you got as a child begin to wear off so you need a booster to keep you protected. Changes in your behavior increase your exposure to certain diseases. Vaccines also protect the people around you who are not able to get vaccinated. Research has shown that all the vaccines you need are safe and effective. For more information, click here.

What vaccines do I need?

  • When you are 11-12 years old, you will need the Tdap, meningococcal conjugate and HPV vaccines.
  • When you are 16 years old, you will need another meningococcal conjugate vaccine as a booster.
  • You need a flu vaccine every year.
  • You may need other vaccines to stay healthy, especially if you are travelling. For more information, click here.

Tdap Vaccine

What diseases does the Tdap vaccine prevent?

Tdap vaccine protects you against three diseases: tetanus, diphtheria, and pertussis (whooping cough).

  • TETANUS (Lockjaw) is caused by bacteria that enters your body through cuts, scratches, or wounds. It is not spread person-to-person. Tetanus causes painful muscle tightening and stiffness; you might not be able to open your mouth, swallow, or even breathe. For more information, click here.
  • DIPHTHERIA is caused by bacteria and is spread person-to-person when an infected person coughs and sneezes.  It causes a thick coating to form in the back of your throat and can lead to breathing problems, paralysis, heart failure, and death. For more information, click here.
  • PERTUSSIS (Whooping Cough) is caused by highly contagious bacteria that is easily spread person-to-person when an infected person coughs or sneezes.   It causes rapid, uncontrollable coughing fits that can cause you to vomit, break ribs or have difficulty breathing and sleeping. For more information, click here.

How can tetanus, diphtheria, and pertussis be prevented?

Tdap vaccine is the best way to prevent tetanus, diphtheria, and pertussis. When you are 11 or 12 years old, you need the Tdap vaccine.

Why is Tdap vaccine especially important for youth?

You probably received DTaP vaccine when you were younger, but the protection from that vaccination is wearing off. You need a booster shot of Tdap vaccine, to keep you fully protected from tetanus, diphtheria, and pertussis. Pertussis can last weeks to months, causing you to miss school and other activities.

NJ Facts
  • About 9 out of 10 New Jersey youths surveyed received one Tdap vaccine.

How do people get HPV?

HPV is spread by skin-to-skin contact during any type of sexual activity. You can get HPV by having oral, vaginal, or anal sex with someone who has the virus. HPV can be passed even when an infected person has no signs or symptoms.  It’s possible to get more than one type of HPV.  There is no test  for adolescents to determine HPV status and there is no cure.

How can HPV be prevented?

HPV vaccine is the best way to prevent infections and HPV-related cancers. When you are 11 or 12 years old, you need the HPV vaccine. It is given in a series over 6 months. It’s important that you get all doses in the series so that you are fully protected.

Why is HPV vaccine especially important for youth?

  • HPV infection is most common in teens and people in their early 20s.
  • You should be completely vaccinated before you are exposed to HPV. Even if you aren’t having sex, you may be engaging in behaviors that can expose you to HPV.
  • It’s the best time to get vaccinated for HPV because your body’s immune system produces a better response to protect against infection.
NJ Facts
  • Every 20 minutes, 1 person in the US gets cancer caused by HPV.
  • The goal is to have at least 8 out of 10 New Jersey youths vaccinated with all 3* doses of HPV vaccine by 2020.
New Jersey Girls
  • About 7 out of 10 New Jersey girls surveyed received 1 dose of HPV.
  • About 4 out of 10 New Jersey girls surveyed received all 3* doses of HPV.
  • The goal is to have at least 8 out of 10, New Jersey girls vaccinated with all 3* doses of HPV vaccine by 2020.
New Jersey Boys
  • About 5 out of 10 of New Jersey boys surveyed received 1 doses of HPV.
  • About 3 out of 10 of New Jersey boys surveyed received all 3* doses of HPV.
  • The goal is to have at least 8 out of 10, New Jersey boys vaccinated with all 3* doses of HPV vaccine by 2020.

*The CDC and ACIP recommendation regarding the number of doses required has been updated as of October 19, 2016:

Meningococcal Conjugate Vaccine

What is meningococcal disease?

Meningococcal (muh-nin-jo-cok-ul) disease is a serious bacterial infection. The disease may result in inflammation of the lining of the brain and spinal cord (Meningococcal meningitis) and/or a serious blood infection (Meningococcal septicemia).  Meningococcal disease can become deadly in 48 hours or less. Even with treatment, 10-15% of people die.  Others have long-term complications such as brain damage, learning problems, skin scarring, hearing loss, and loss of arms and/or legs.

What are common symptoms of meningococcal disease?

  • Confusion
  • Fatigue (feeling very tired)
  • Fever and chills
  • In later stages, a dark purple rash
  • Nausea and vomiting
  • Rapid breathing
  • Sensitivity to light
  • Severe headache
  • Stiff neck

For more information, click here.

How do people get meningococcal disease?

The bacteria are spread from person-to-person through the exchange of saliva (spit), coughs, and sneezes. You must be in direct (close) contact with an infected person’s secretions to be exposed.

Examples of close contact include:

Kissing Sharing anything that comes into contact with the mouth (drinking glasses, smoking materials, eating utensils, cosmetics, or lip balm)
Living in the same house Sleeping in the same residence (sleep overs)

The bacteria are not as contagious as the common cold or flu and does not spread by casual contact or breathing the air where a person who is sick has been.

About 1 out of 10 people carry meningococcal bacteria in their nose and throat, but don’t get sick. These people are known as carriers. Although carriers do not have any signs or symptoms, they can still spread the bacteria and make others sick.

How can meningococcal disease be prevented?

Meningococcal conjugate vaccine is the best way to prevent meningococcal disease. The vaccine protects against four of the five types of bacteria (A, C, W, Y)  that cause almost all cases of meningococcal disease worldwide. The first dose is routinely administered when you are 11-12 years old. When you are 16 years old, you will need a booster shot.

There is a different vaccine to prevent against meningococcal type B disease.  To learn more, click here.

Why is meningococcal conjugate vaccine especially important for youth?

Teens and young adults aged 15-24 years are at increased risk for meningococcal disease. Meningococcal disease is a serious infection and the consequences can be devastating.

NJ Facts
  • About 9 out of 10 New Jersey youths surveyed have received the first dose of meningococcal conjugate vaccine.
  • About 3 out of 10 17-year-olds  surveyed in the US received the second dose (booster dose) of meningococcal conjugate vaccine.
  • By 2020, the goal is to have at least 8 out of 10 New Jersey youths vaccinated with the meningococcal conjugate booster dose by the age of 17.

Flu Vaccine

What is influenza?

Influenza or “flu” is a highly contagious (easily spread) respiratory disease caused by influenza viruses that infect the nose, throat, and lungs. As many as 1 in 5 people get sick with the flu each year.

Symptoms include:

  • body aches
  • coughs
  • fever/chills
  • headaches
  • sore throat

Unlike many other viral respiratory infections, such as the common cold, the flu can cause severe illness and life-threatening complications in many people. Young children, pregnant women, people with certain health conditions (such as asthma, diabetes, kidney disease, or heart disease), and people 65 and older are at increased risk. Each year more than 200,000 people in the US are hospitalized from flu-related complications.

How do people get the flu?

  • You can get the flu from an infected person when they cough, sneeze, or talk or by touching a surface that has flu virus on it and then touching your eyes, nose, or mouth.
  • Infected people can spread the flu a day before they feel sick and for about a week after symptoms begin.

How can the flu be prevented?

  • The best way to prevent the flu is to get a flu vaccine every year if you are 6 months old or older.
  • In the United States, flu season occurs in the fall and winter, but can sometimes last until May. It’s important to get vaccinated soon after vaccine becomes available in your community.

Why is the flu vaccine especially important for youth?

  • Protection from last year’s flu vaccine wears off, so to be fully protected you need to be vaccinated for the current flu season.
  • The flu can be very serious, even for healthy youth, and especially for youth with certain health conditions like asthma or diabetes.
  • If you get the flu you could miss one to two weeks of school and activities. Some youth have painful complications like sinus infections, ear infections, or pneumonia.
  • By getting a flu vaccination, you protect yourself and your friends, grandparents, parents, and siblings from potentially life-threatening diseases.
NJ Facts
  • During the 2015-2016 flu season, about 5 out of 10 New Jersey youths surveyed received the flu vaccine.
  • The goal is to have at least 8 out of 10, New Jersey youths vaccinated with flu vaccine each year by 2020.

Top 3 reasons you should get the flu vaccine every year:

  1. Protect yourself. While the flu may not seem like a big deal, it can be very serious for some youth, especially youth with certain health conditions. It is important to receive a flu vaccine every year. Read Martin’s Story.
  2. Be a Hero. When you are vaccinated against the flu, you can stop the spread to people around you. The flu can be life threatening to babies and elders, so you can save a life by stopping the disease.
  3. Get better faster. Even if you do get the flu, it will be less severe, meaning you won’t feel as bad and it won’t last as long.

Other Vaccines

Everyone needs vaccines, including you!


There are now vaccines to prevent against most meningococcal disease caused by type B.  If you are 10 or older and at increased risk, it is recommended that you receive a MenB vaccination.  When you are 16-23 years old, you can receive a MenB vaccination (preferably at 16 through 18 years old), in addition to the routinely administered meningococcal conjugate vaccine, to help provide broader protection.  Ask your healthcare provider if you should receive this vaccine.

Travel Vaccines

Are you going to a different country for vacation, study abroad, a sports tournament or to volunteer? That’s great! But before you start packing, check CDC’s Travelers’ Health to see if you need additional vaccines to keep you healthy on your adventure.
