What is the immune system and what its function ?

The immune system is a complex network of cells and proteins that defends the body against infection. Source

The immune system works by recognising the difference between your body’s cells and alien cells, allowing it to destroy any that could be potentially harmful. Source

What age is a child’s immune system fully developed?

An infant’s immune system doesn’t mature until around 2 to 3 months. In those first few months, the immune system, especially cell-mediated immunity, becomes more developed.

That means that a 2 weeks old baby’s immune system can’t fight viruses or bacteria nearly as a 3 months old infant’s can. Sourse.

That doesn’t mean that your newborn baby is not protected against germs and viruses. Antibodies are passed from mother to baby through the placenta during the third trimester, and this gives the baby some protection when they’re born.

After birth, more antibodies are passed on to the baby in colostrum and in breast milk.

That’s why breastfeeding -if you are able to- is the best choice ever for the health of your baby. Add to that vaccination during the pregnancy, at birth, and then at 6 weeks, 4 months…etc

So, although antibiotics are effective and potentially life-saving for bacterial infections in children.

But, unnecessary antibiotics expose individual children to potential side effects, including diarrhoea, vomiting, rashes and allergic reactions.

The overuse of antibiotics also increases the risk of bacterial resistance in the wider community. This is when commonly used antibiotics become ineffective against some bacteria, making it difficult, or even impossible, to treat some infections.

For all the reasons above, if your child have a simple viral infection, don’t rash the pediatric to write an antibiotic prescription for him/her.
