Immunizations for Children
We offer the following services for children under 18, accompanied by a parent or legal guardian (see Contacts page for minor consent policy):
- Travel health visit (including vaccines and prescriptions)
- Flu vaccine
- HPV (Human Papillomavirus) vaccine (Gardasil-9) for males and females 9+ years of age
- Tdap (Tetanus-diphtheria-pertussis) vaccine (ages 7 years and up)
- Meningococcal ACWY and Meningococcal B vaccines (ages 11 years and up)
Please note: AITC is not a primary care clinic, and does not offer routine childhood immunization services. Please visit your pediatrician, family doctor, or neighborhood clinic for routine pediatric immunizations.
Appointments are required for international travelers. Same-day appointments are available.
Vaccines other than travel vaccines are offered daily on a drop-in basis. No appointment is necessary.
A blood test can provide proof of immunity, which helps you avoid getting unneccessary vaccines. See our information sheet: Testing for Immunity to Vaccine-Preventable Diseases.
AITC can check your immunity to:
- Hepatitis A
- Hepatitis B
- Measles / Mumps / Rubella
- Yellow fever
You can be infected with hepatitis B and not know it. AITC offers testing to determine your hepatitis B infection status. See our information sheet: Testing for Hepatitis B Infection. Consider hepatitis B testing if you answer yes to any of the following:
- Were you or your parents born in Asia, Pacific Islands, Africa, Eastern Europe, or the Amazon Basin in South America?
- Have you had a sex partner with hepatitis B or lived in the same household as someone with hepatitis B?
- Are you a male who has had sex with males?
Results are available within 2-5 business days. We will mail or fax your results; you may discuss your results with an AITC nurse by phone or in person, at no additional charge.
Blood testing is offered daily on a drop-in basis; no appointment is necessary -but we recommend that you arrive at least 1 hour before closing to allow us time to process your sample.
There is a cost for each test, plus a small fee to draw your blood. See prices.
TB (tuberculosis) Testing
TB testing shows whether your immune system recognizes TB or not. Here’s how it works:
A “positive” test result means that your immune system recognizes TB, because you were exposed to TB infection in the past. A positive result does not mean that you have active TB disease right now — the TB in your body could be either active or inactive. Active TB is bad for your health and contagious to other people, while inactive TB is not. And so, after a positive TB test, you will need further testing to determine whether you have active or inactive TB infection.
A “negative” test result means that your system does not recognize TB, most likely because you have never been exposed to TB. After a negative result, further testing is usually not needed.
AITC offers 2 types of tests for TB.
- TB skin testing. This is the traditional (and least expensive) method. It requires 2 visits to clinic. On the first visit, a nurse will place a tiny amount of test fluid in the skin of your forearm using an ultra-thin needle. You will be required to return to the clinic in 48-72 hours to have a nurse read the test by checking the skin of your forearm. TB skin tests are regularly offered Mon, Tue, Wed, and Friday. We do not perform TB skin testing on Thursdays (and on the Friday before a long weekend), as it will not be possible to read the test within 72 hours.
- TB testing using the QuantiferonTB-Gold In-Tube (QFT) blood test. This method has 2 advantages: 1) In people born outside the USA who received an anti-TB vaccine called BCG vaccine as children, the QFT test is more accurate than TB skin testing; 2) Just one clinic visit is required for the blood test, and so the QFT can be performed with clients who are unable to return for a second visit. Please note: QFT results are available 3-4 business days after your test.
TB testing is offered daily on a drop-in basis; no appointment is necessary. Please note that TB skin testing is unavailable on Thursdays and on the Friday before a long weekend.
AITC offers seasonal flu vaccine every year, starting in the late summer. Our flu vaccine express service will get you in and out quickly.
Note that in the US and Europe, flu season occurs December through April. But in the Southern Hemisphere, flu season occurs during their winter, from May though September. And in the tropics, there is no flu season … flu transmission occurs throughout the entire year.
We carry many varieties of flu vaccine:
- Regular injection for persons age 3 years and up
- Preservative-free injection for young children ages 6-35 months and pregnant women
- High dose flu vaccine for adults age 65 and up
- Vaccine by nasal spray (FluMist quadrivalent) for healthy, non-pregnant persons age 2-49 years
- Egg-free flu vaccine (FluBlok)
Flu vaccination is offered on a drop-in basis. No appointment is necessary. See prices.
Flu Vaccination for Seniors Age 65+
Seniors age 65+ have a choice: (a) the regular flu vaccine that has been around for many years, or (b) the high-dose flu vaccine that first became available during the 2010-11 flu season.
The high-dose flu shot has 4 times the active ingredient, and so is stronger than the regular flu shot. In clinical studies, seniors getting high-dose vaccine developed better immunity to flu (but had slightly more side effects of arm soreness) than seniors getting regular vaccine.
Vaccination against pneumococcal infection is now part of routine childhood immunization before the age of 2 years. However, most adults today have never received this vaccine.
The CDC’s Advisory Committee on Immunization Practices recommends vaccination against pneumococcal disease for adults with specific situations:
- persons age 19 – 64 years who smoke cigarettes or have asthma; and
- persons age 2 – 64 years with chronic heart or lung disease, diabetes, or a weakened immune system
- seniors age 65 years and up (Pneumovax23 for all seniors, plus Prevnar13 for seniors who would like the extra protection)
The CDC has additional information on pneumococcal vaccination.
Pneumococcal vaccination is offered at AITC on a drop-in basis. No appointment is necessary. See prices.
Live Vaccines during Pregnancy
If you think you need a live vaccine (see list below) for work, school, personal health, or international travel, please take precautions to avoid becoming pregnant before your vaccination, and for at least one month after your vaccination. Here’s why:
Pregnant women may safely be immunized with vaccines that contain inactivated (killed) viruses or bacteria. Most vaccines are of this type. For example, it is OK to receive whooping cough vaccine (Tdap), a flu shot, or the injection form of typhoid vaccine (Typhim Vi®) while pregnant.
But some vaccines contain live, attenuated (weakened) viruses or bacteria. We generally avoid administering live vaccines to women who are pregnant or who might be pregnant. It is possible, in theory, that the live vaccine strain could infect the fetus. Of all the live vaccines, only the smallpox vaccine has actually been shown to cause injury to the fetus. (We do not administer smallpox vaccine at AITC.) The rest of the live vaccines actually appear to be safe during pregnancy. However, due to the small number of women in the research studies, a bit of uncertainty still remains, and so we are very cautious about administering live vaccines to women who are pregnant or who might be pregnant.
Live vaccines given at AITC:
- Yellow Fever Vaccine (YF-Vax or Stamaril)
- Measles, Mumps, Rubella Vaccine (MMR)
- Shingles Vaccine (Zostavax)
- Chickenpox Vaccine (Varivax)
- Nasal Spray Flu Vaccine (FluMist)
- Oral Typhoid Vaccine (Vivotif)
- Cholera Vaccine (Vaxchora)
We will always ask if you are pregnant before administering any vaccine, but especially before giving you a live vaccine. If you are unsure whether you’re pregnant, or if you have had unprotected intercourse since the start of your most recent period, and you need a live vaccine, we may recommend that you wait until your next period starts and document a negative pregnancy test, before administering live vaccine.
