Vaqta Warnings and Precautions

Before receiving the Vaqta vaccine, it is important that your healthcare provider knows if you have an immune-suppressing condition or a moderate or severe illness. Other safety precautions with Vaqta include warnings of potential drug interactions and risks for women who are pregnant. You may not be able to receive it if you have had any sort of a reaction to other vaccines.

What Should I Tell My Healthcare Provider?

You should talk with your healthcare provider before you receive Vaqta® (hepatitis A vaccine) if you have:
  • An immune-suppressing condition, such as HIV, AIDS, diabetes, or cancer
  • Had any sort of a reaction to any vaccine in the past
  • A moderate or severe illness
  • Any allergies, including to foods, dyes, or preservatives.
Also, let your healthcare provider know if you are:
  • Pregnant or thinking of becoming pregnant
  • Breastfeeding.
You should also tell your healthcare provider about all other medications you are taking, including prescription and nonprescription medicines, vitamins, and herbal supplements.

Specific Precautions and Warnings for Vaqta

Some warnings and precautions to be aware of prior to receiving this vaccine include the following:
  • Vaqta does not contain thimerosal (a mercury-containing preservative). People who are concerned about exposure to this substance can be confident that this vaccine does not even contain trace amounts of thimerosal. Some people are also concerned about the aluminum content of vaccines. Vaqta contains 0.45 mg of aluminum per mL per adult dose and 0.225 mg of aluminum per pediatric dose.
  • Hepatitis A has a long incubation period (15 to 50 days). This vaccine may not prevent infection in people who were exposed to the virus in the days or weeks before receiving the vaccine. In these cases, it may look like the vaccine did not work or that it caused the illness, but this is not the case.
  • You can receive Vaqta if you have a mild illness, such as the common cold. However, it is usually best to postpone the vaccine in the case of a moderate or severe illness.
  • Make sure your healthcare provider knows if you have ever had any serious reactions to any vaccines in the past.
  • If you have an immune-suppressing condition, Vaqta may not be as effective as usual for protection against hepatitis A, as your immune system may not be fully capable of responding to the vaccine.
  • Vaqta vials and prefilled syringes contain latex, which could potentially cause an allergic reaction in individuals allergic to latex.
  • Vaqta is a pregnancy Category C medication. This means it is unknown if it is safe for use during pregnancy (see Vaqta and Pregnancy).
