Is childhood immunisation done with live attenuated vaccine?

A live attenuated vaccine uses a weakened form of a germ. The weakened organism is intended to stimulate immune recognition without causing the usual illness in a healthy person. Because the immune response can resemble the response to natural infection, some live vaccines provide useful protection after the scheduled dose or doses.

Not every child can receive every live vaccine at every time. The clinician considers age, previous doses, immune-system problems, medicines that suppress immunity, pregnancy exposure in the household and recent illness. The product information and local childhood schedule guide the decision.

Bring the child’s vaccination record and tell the clinician about immune conditions, long-term medicines, allergies and any previous vaccine reaction. Ask whether the planned product is live attenuated and whether it should be given at the same visit as another vaccine or arranged separately.

Follow the clinic’s aftercare instructions. A mild fever, tiredness or soreness can occur. Let the child rest, offer fluids and use a fever medicine only when a clinician has advised that it is suitable for the child.

Ask the clinic for advice if the child develops a reaction that is worsening, persistent or affecting feeding or activity. Get urgent help for breathing difficulty, facial or throat swelling, collapse, a seizure, or marked difficulty waking. A prompt assessment is appropriate for these warning signs after any vaccine.

Is today’s vaccine live attenuated? Why is this type appropriate for my child? Are there immune conditions or medicines that affect eligibility? What reactions are expected, and when should I seek help?
