Immunizations are one of the most important ways to protect children, adults, and families from serious diseases. Public health provides information for parents, health care professionals, school nurses, childcare providers, and others who are making decisions about or recommending immunization as a means to prevent diseases.

Our goal is to assist individuals in making good choices that will protect them, their children, and the public’s health.


Adults need vaccines too.

The department’s Health Clinic  offers some adult vaccines by appointment and for a fee. The adult vaccines offered are:

  • Influenza (see below)
  • Tdap (pertussis and tetanus)
  • Meningitis
  • Hepatitis B
  • Pneumonia
  • Pre-exposure rabies (see below)

Consultation regarding adult recommendations is available by calling 301-475-4419. For more information about adult immunizations, click here.


The health department is responsible for enforcing legislation requiring proof of immunization as a condition for school entry. School nurses and health department nurses are partners with families in meeting school requirements.

For help, call your school’s nurse or the health department at 301-475-4419.

Pre-teen and Adolescent

As kids get older, protection from some childhood vaccines begin to wear off.

Pre-teens and adolescents can also develop risks for other diseases. A health check-up, with your family doctor, is the right time for pre-teens and adolescents to get vaccines including the tetanus and pertussis (Tdap), meningococcal/meningitis, and Human Papillomavirus vaccine (HPV).

The department’s Health Clinic offers the meningitis vaccine to high school students and college students planning to live in a dormitory by appointment and for a fee.


The Vaccines for Children Program is a federally funded free vaccine program for eligible children provided through private pediatric health care providers.

St. Mary’s County Health Department staff is available to refer children to providers and determine eligibility for the Maryland Children’s Health Insurance Program, which covers well child visits, by calling 301-475-4330.
