Babies are vulnerable to diseases due to their developing immune systems. With so many potential risks, such as viruses, bacteria, and infections. That is why, among the most important things to keep in mind as a new parent is ensuring your baby stays healthy and protected. 

One of the most effective ways to protect your baby is through vaccination. Vaccines are essential in safeguarding your baby from serious, preventable diseases that could otherwise affect their health and development.

This blog will guide you through the essential vaccines your baby needs during their first year. We’ll explain why these shots are necessary, when they’re given, and how they work to strengthen your baby’s immunity. 

Why Vaccination is Important for Your Baby

Vaccinations are one of the most significant advancements in modern medicine. They work by stimulating the body’s immune system to produce a response to specific pathogens without causing the disease itself. 

Vaccinating your baby not only protects them from potentially life-threatening illnesses, but it also helps protect the larger community by creating what’s known as herd immunity.

Without vaccines, diseases like measles, whooping cough, and polio could spread easily, putting babies and other vulnerable individuals at risk. Vaccinating your baby according to the recommended schedule helps to ensure that these diseases do not return to your community.
