Quinvaxem Vaccine is a 5 in 1 vaccine given to infants and young children. It provides active immunization against five severe diseases namely Diphtheria, Haemophilus influenzae type b, Hepatitis-B, Pertussis, and Tetanus. It boosts the immune system and produces protective antibodies against these diseases. Quinvaxem Vaccine is to be administered by your child?s doctor only. It is injected into the thigh muscles of infants. In older children, the vaccine is administered into the arm muscle. It is administered in 3 doses, each 4 weeks apart, preferably before the age of 6 months. Generally, it is recommended to administer the 1st dose at 6 weeks of age, the 2nd dose at 10 weeks of age, and the 3rd dose at 14 weeks of age. If a child has not received the 1st dose by the age of his initial year, start vaccination as soon as possible and consult your child?s doctor for the schedule.Quinvaxem Vaccine can cause some minor and temporary side effects such as fever, irritation, loss of appetite, injection site reaction (pain, swelling, redness), and skin rash. However, these episodes do not last very long and subside on their own. If worrisome, do seek the doctor's help.Talk to your child?s doctor before vaccination if your child has a history of liver problems, kidney problems, blood disorders, birth defects, heart problems, lung problems, severe pain or swelling of the limbs, or Guillain-Barr? syndrome. Also, let your doctor know if your child has or had any severe allergic reactions to any medicine. You should also consult your doctor if your child has ever been in a coma or has had brain or nervous system problems like seizures before scheduling a vaccination appointment. This information is important for the doctor to prepare a corresponding vaccination schedule.
