Adult Immunizations

Services at the Adult/Foreign Travel Immunization Clinic will no longer be provided effective July 1, 2017. Adult Safety Net Program vaccines will remain available for uninsured adults at all HHD Immunization Clinic Locations.

In the U.S., vaccines have greatly reduced or eliminated many infectious diseases that once routinely killed or harmed many infants, children, and adults. However, the viruses and bacteria that cause vaccine-preventable disease and death still exist and can be passed on to people who are not protected by vaccines. Every year thousands of adults in the U.S. still suffer serious illness, are hospitalized, and even die due to disease for which vaccines are available.

Like infants and children, adults are also at risk for contracting vaccine-preventable diseases. In addition to becoming severely ill, infected adults risk spreading these diseases to infants who are too young to be vaccinated.

All adults need:

  • Influenza (flu) vaccine every year
  • Td or Tdap vaccine

Other vaccines you may need as an adult are determined by factors such as your age, lifestyle, health conditions, international travel, and previous vaccines you have received. Learn more about what other vaccines may be recommended for you and talk to your healthcare professional about which vaccines are right for you.

Adult Safety Net

The Adult Safety Net (ASN) Program provides vaccine purchased with public funds to participating clinics to be used for immunizing uninsured adults.
Currently, the vaccines offered through the ASN Program include the following: 
  • Hepatitis A vaccine;
  • Hepatitis B vaccine;
  • Combination hepatitis A-hepatitis B vaccine;
  • Human papillomavirus (HPV) vaccine;
  • Measles, mumps, & rubella (MMR) vaccine;
  • Meningococcal vaccine;
  • Pneumococcal polysaccharide vaccine (PPSV23);
  • Pneumococcal conjugate vaccine (PCV13);
  • Tetanus, diphtheria, & pertussis(Tdap) vaccine; and
  • Tetanus-diphtheria (Td) vaccine;
  • Varicella vaccine; and
  • Zoster vaccine.

Why do adults need to be vaccinated?

Like infants and children, adults are also at risk for contracting vaccine-preventable diseases. In addition to becoming severely ill, infected adults risk spreading these diseases to infants who are too young to be vaccinated. The solution is to vaccinate our adult population to prevent infection with one of these potentially devastating diseases.

Do you know which adult vaccines you need? Take the quiz. Don't wait. Vaccinate. CDC

Who is eligible to receive ASN vaccines?

  • You are 19 years of age or older, and
  • You do not have health insurance.

Who is not eligible to receive ASN Program vaccines?

  • Adults who have Medicare, Medicaid, or any other insurance, including private insurance
  • Adults who are underinsured for adult vaccines (e.g., those who have healthcare insurance that does not cover adult vaccines)
  • Individuals younger than 19 years of age
If I qualify for ASN Program vaccine, do I have to pay anything?
ASN Program vaccines are supplied to participating medical providers at no cost. This means that ASN Program providers cannot charge a fee for the vaccine itself. However, providers are allowed to charge an administration fee of up to $25 for each vaccine that is administered. Although ASN Program providers may charge this administration fee, they cannot deny the vaccine because of an inability to pay it.

Where can I go to get ASN Program vaccines?
Visit the Department of State Health Services website for a list of participating providers.

For children age 0-18, please refer to the Texas Vaccines for Children website for more information.
