Immunization protects you from disease.Get protected, get immunized.
IG is made from blood and contains antibodies.
IG gives fast protection against measles or hepatitis A, but it is not long lasting. For long lasting protection, immunization with a measles or hepatitis A containing vaccine is needed.
IG is given after contact with the measles virus to unprotected people who are at risk for serious illness (e.g., weak immune system, pregnant woman, baby under 1 year of age).
IG is given after contact with the hepatitis A virus to unprotected people who are at risk for serious illness (e.g., liver disease, weak immune system, baby under 6 months of age). IG must be given within a certain time after contact with the virus.
People need 1 dose of IG as soon as possible after contact with the virus. The size of the dose depends on the person’s body weight.
For people who have been in contact with hepatitis A or measles virus, IG helps prevent the disease or helps prevent serious illness in those who do get disease.
IG is one of the safest blood products available. Canadian Blood Services carefully screens donors and tests all blood collected. The blood of donors is not used if the donor has known risk factors or tests positive for an infectious diseases. IG is treated with heat and chemicals to kill germs that might be present. The risk of getting an infection from IG is very small.
If you think you have been in contact with hepatitis A or measles, call Health Link at 811 to discuss.
If IG is needed, it will be given at your local public health office.
Reactions to IG are usually mild and go away in a few days. They may include:
Hives and general swelling may occur.
It is important to stay for 15 minutes after IG is given because people can have a rare but serious allergic reaction (anaphylaxis). If anaphylaxis happens, you will be given medicine to treat the symptoms.
Unusual reactions can happen. Call Health Link at 811 to report any unusual reactions.
Talk to your healthcare provider before having IG if you:
You can have IG if you have a mild illness (e.g., cold), even if you have a fever.
IG can interfere with live vaccines. You need to wait for 3 to 6 months (depending on the dose you had) after having IG before you can have a live vaccine, including measles-containing vaccine. If you had a live vaccine less than 14 days before having IG, ask a public health nurse if the live vaccine needs to be repeated.
