Why Immunizations Are Important For Your Child

Posted | 0 comments

Immunization has reduced child mortality rates significantly. For instance, immunization is responsible for the eradication of polio in the US, according to the Centers for Disease Control and Prevention (CDC). In spite of this, some parents believe that vaccines can harm their children. Here are the pros and cons of childhood vaccination:


Disease-Causing Pathogens Still Exist
Although most of the diseases that were once fatal to children have been eradicated in the developed world, the viruses and bacteria that cause the same diseases still exist. As such, failing to have your children immunized increases their risk of contracting diseases like influenza, pneumococcal disease, and human papillomavirus.

Data from the National Foundation for Infectious Diseases (NFID) shows that the cost of treating vaccine-preventable diseases in the US exceeds $10 billion every year. This is in addition to lost workdays that can range from 5-16 days. Vaccines can help lower these financial and productivity losses. Given that vaccines are provided at no cost via federally funded programs, immunizing your child is financially sensible.

Protect Yourself and Others

Besides children, immunization benefits others like parents, a child’s siblings, and close relatives like grandparents, according to the NFID. This is because vaccine-preventable diseases can spread from young kids to people who have close contact with them. The bad news is such diseases can prove fatal or develop into serious medical conditions in the very young and the elderly. With this in mind, immunization protects your child, you, and your family. The Pediatric Academy Society says that immunization prevents 10.5 million infectious disease cases per year in the US.

Reduce the Likelihood of Premature Adult Death

Even in a developed country like the US, vaccine-preventable diseases are responsible for more fatalities than much feared diseases like breast cancer. Figures from the NFID show that vaccine-preventable diseases cause 50,000 adult deaths in the US annually. By taking your child for immunization, you will reduce a child’s likelihood of dying prematurely as an adult from vaccine-preventable diseases.

Immunization Works

Over the years, dissenting voices have surfaced questioning the efficacy of vaccines. The truth is immunization works. Data published by the American Academy of Pediatrics shows that vaccination has lowered vaccine-preventable infections by over 90%. Furthermore, the AAP says that the effectiveness of childhood vaccines in preventing diseases like mumps, tetanus, and diphtheria is high, ranging from 90-99%. As a result, children who contract vaccine-preventable diseases develop mild symptoms that are rarely fatal or could cause disabilities.


Adverse Side Effects

According to the CDC, any of the vaccines given to children in the US can cause side effects. However, side effects if any rarely cause serious problems. In fact, most adverse effects tend to be mild and last no more than a few days. This is because vaccines contain weakened strains of specific disease-causing microorganisms. Additionally, side effects generally vary from one vaccine to another. Adverse effects documented by reputable bodies such as the Institute of Medicine (IOM) and the National Academy of Sciences include:

• Protracted crying
• Brachial neuritis
• Anaphylaxis
• Deltoid bursitis
• Shock
• Chronic nervous system dysfunction
• Guillian Barre Syndrome (GBS)
• Infection caused by smallpox, measles, varicella zoster, and polio vaccine strains.
• Febrile seizure

Other possible complications, according to the CDC include fainting and dizzy spells, mild fever, fatigue, swelling at point where vaccine shot was administered, diarrhea, mild rash, runny nose, wheezing, vomiting, and inconsolable fussiness. The CDC says most of these symptoms clear within 2-3 days.


Immunization has vastly improved the health outcomes of young children who were a century or so ago at the mercy of diseases such as polio, chickenpox, measles, and whooping cough. Vaccination benefits include preventing proliferation of disease-causing microorganisms that still exist and preventing premature adult deaths. Vaccination side effects include shock, headaches, vomiting, and anaphylaxis. Nevertheless, symptoms clear within days.
