- Young children vaccination data refers to children from the birth cohorts 2016—2019 and includes Young Children (0—35 months).
- Kindergarten vaccination data reflects the corresponding school year (for example, data labeled 2024 represents the 2023—2024 school year).
- Teen vaccination data include ages 13—17 years.
- Adults vaccination data include ages 18+
- Combined 7 Series refers to children who received the full recommended set of seven vaccines: 4 doses of DTaP, 3 doses of poliovirus vaccine (IPV), 1 dose of MMR, the full Hib series, 3 doses of Hepatitis B, 1 dose of Varicella vaccine, and 4 doses of Pneumococcal conjugate vaccine (PCV).
- Varicella protects against chickenpox.
- MenACWY protects against meningococcal disease (types A, C, W, Y).
- MMR protects against measles, mumps, and rubella.
- HepB protects against hepatitis B.
- HPV protects against human papillomavirus, which can cause cervical and other cancers.
- Tetanus protects against tetanus (lockjaw).
- DTaP protects against diphtheria, tetanus, and pertussis (whooping cough).
- Polio protects against poliomyelitis.
- PCV protects against pneumococcal disease (pneumonia, meningitis, sepsis).
- COVID vaccines protect against COVID-19 infection and severe disease.
Vaccination is the administration of a vaccine to help the immune system develop protection from disease. Vaccines contain a weakened microorganism or virus, or proteins or toxins from an organism, not strong enough to infect someone but to help build a tolerance to the disease.
Unlike in some countries around the world, vaccines are easily accessible in the United States. The seasonal influenza vaccine, or flu shot, is often offered for little to no cost at clinics across the United States every year during flu season. Many of these wide-available vaccines are for some of the most aggressive contagions that can be particularly harmful to children, the elderly, and people with autoimmune disease. Vaccines not only protect the individual receiving the vaccine, but also the community preventing the spread of these diseases.
Around the world, more and more people are receiving life-saving vaccines. The Centers for Disease Control and Prevention has a thorough list of vaccines used in the United States. An emphasis is placed on children between the ages of zero to 10 to receive a specific list of vaccines: hepatitis A (HepA); hepatitis B (HepB); diphtheria, tetanus, and acellular pertussis (DTaP); Hib, PCV13; inactivated poliovirus (IPV); inactivated influenza (IIV) or live-attenuated influenza (LAIV); measles, mumps, rubella (MMR); and varicella (VAR).
While there are no federal laws regarding the requirement of vaccinations, all 50 states have legislation requiring children attending public school to be vaccinated against diphtheria, tetanus, and acellular pertussis (DTaP); polio (IPV); measles and rubella (MMR); and varicella (chickenpox). All states and the District of Columbia, however, allow medical exemptions for children who have a medical condition preventing them from receiving a vaccine.
According to the American Academy of Pediatrics, routine immunizations for children are vital for both individual and society health. Because immunization rates vary from state to state, some communities have recently experienced outbreaks of preventable diseases due to a lack of vaccinations. Low vaccination rates can be affected by medical exemptions, parents’ choice (anti-vaccination movement), or by lack of health care or health insurance.

Massachusetts has the highest vaccination rates in the United States. According to the director of the Massachusetts Department of Public Health’s immunization program, it is likely attributed to the facts that the state has a strong provider network and most children receive care in a primary care practitioner office. Additionally, “Massachusetts has had essentially universal healthcare for children longer than what’s been happening nationally.”
Alaska has the lowest vaccination rate in the United States. Officials say that vaccination rates in Alaska are improving, but that more efforts are needed to maintain herd immunity.
