When babies are born, their immunity to disease is weak - their immune system is constantly changing and developing throughout childhood. Therefore, they are more resistant to bacteria and viruses than adults. Breastfeeding helps boost immunity because the baby gets the main antibodies against disease from breast milk.
However, vaccinations are still important, especially if your baby is fed formula. When a baby is vaccinated, a very weak disease is injected into his body, and the immune system is strengthened and learns to fight the disease.
It is rare today due to the development of immunity to many diseases; Once unvaccinated babies become infected, that's why immunization is so important.
When to immunize All babies, even premature ones, should be vaccinated after about two months - when they begin to lose the immunity they acquired from you. Side effects of immunity in infants Immunizations are safe and allergic reactions to vaccines are very rare. Some babies develop swelling or redness at the injection site. If your baby has these symptoms, a good painkiller can help.
Sometimes babies suffer from very mild symptoms due to the vaccine, but they will not have any serious complications as a result. If your baby is not protected, the real risk is when the disease itself becomes infected. If you think your baby is having an adverse reaction to the vaccine, see your doctor.
