Newborn and infants are among the immunocompromised population. This means that compared to others, they are more vulnerable to infections that might lead to death or long-term complications. The good news is, many diseases, such as hepatitis B, pneumonia, and measles, are vaccine-preventable. In general, the child receives majority of these vaccines within their first year of life. That’s why it’s crucial for parents to keep track of their child’s pediatric vaccination schedule.
