Your Baby's First Immunization

When it's time to immunize

Immunization needles may cause your baby mild pain, but it goes away very quickly. Here are some ways to make it easier on both of you:

Before you go

Take you baby's immunization record with you to the doctor's or public health office (CLSC in Québec). When you get there, you might be asked a few questions about your baby's general health and whether he or she has any allergies or health problems.

At the appointment

If you are relaxed and positive, your baby or child is likelier to be so, too. Cuddle him or her while the needle is being given: studies show that babies who are held during immunization cry less. If you're breastfeeding, try feeding your baby just before or during the needle for comfort. Also, your gentle, soothing voice or touch can help comfort your baby.

After it's over

Most babies are absolutely fine after immunization. Yours may have no reaction at all to the vaccine -- but could be cranky, fussy or sleepier than usual. He or she may also have a low fever, a sore red spot, or a small swelling where the needle was inserted. These reactions are common and normal and last for a few days at most. You can give your baby medicine to help with the pain and lower a fever -- ask your doctor, nurse or pharmacist about what to give.

Under the weather?

If your child is sick or has a fever when it's time for his or her immunization, talk to your doctor or nurse. They can assess whether it's OK to give the vaccine or if it's better to wait.

Don't rush out

You'll be asked to stay in your doctor's or public health office (CLSC in Québec) for 15 minutes after your baby's immunization to check for allergic reactions. If you know your baby is allergic to something, be sure to tell your doctor or nurse before any vaccine is given. With any medication, there is always the slight chance of a serious allergic reaction. Signs of serious allergic reaction include breathing problems (wheezing), swelling, and blotchy skin or hives on the body or around the mouth. If you see any of these symptoms or are concerned about your child's health, talk to the doctor or nurse immediately.

Once you're back home

Call your doctor, public health office or CLSC if your baby has any of the following symptoms after immunization:

• A fever above 40 °C or 104 °F
• A seizure or convulsions -- often related to a very high fever
• Crying or fussing for more than 24 hours
• Worsening swelling where the needle was given
• Unusual sleepiness or unresponsiveness

You know your baby best. If you notice anything that is not normal for her after an immunization, it's always a good idea to check with your doctor or health professional.
