Vaccination has been one of the most successful public health interventions ever developed. Widespread use of vaccines over the past 50 years has led to the eradication of smallpox and significant reductions in many other dangerous infectious diseases. However, as some diseases have declined, concerns about vaccine safety have emerged among some parents. This article aims to provide an overview of commonly used pediatric vaccines and address some concerns regarding vaccine safety and effectiveness.
What Vaccines are Recommended for Children?
The Centers for Disease Control and Prevention (CDC) recommends that all children routinely receive vaccinations to protect against 14 potentially serious diseases by age two. Some of the key vaccines included in the pediatric immunization schedule are:
– Diphtheria, Tetanus, Pertussis (DTaP): Protects against three serious bacterial infections – diphtheria, tetanus (lockjaw), and pertussis (whooping cough). 5 doses are recommended, starting at 2 months of age.
– Haemophilus influenzae type b (Hib): Protects against Hib meningitis (a serious infection of the lining of the brain and spinal cord) and other Hib diseases. 4 doses are recommended, starting at 2 months of age.
– Hepatitis B: Protects against life-threatening liver infections. 3 or 4 doses are recommended, starting at birth.
– Influenza: Protects against seasonal influenza. Annual vaccination is recommended starting at 6 months of age.
– Measles, Mumps, Rubella (MMR): Protects against measles, mumps, and rubella. 2 doses are recommended, the first at 12-15 months and the second at 4-6 years.
– Pneumococcal: Protects against pneumococcal disease caused by Streptococcus pneumoniae bacteria. 4 doses are recommended starting at 2 months of age.
– Polio: Protects against poliovirus, a contagious virus that causes paralysis in some cases. 4 doses are recommended, starting at 2 months of age.
– Rotavirus: Protects against rotavirus, the most common cause of severe diarrhea among babies and young children worldwide. 2 or 3 doses are recommended starting at 2 months of age.
Are Vaccines Safe?
One of the biggest concerns parents have regarding vaccinations revolves around safety. While no medical intervention is completely risk-free, studies over many years have shown that vaccines are very safe for most people. Potential side effects are usually mild and short-lived, such as a sore arm or low-grade fever, while severe reactions are extremely rare. Some other commonly held misconceptions about vaccine safety include:
Autism Concerns: Numerous large-scale scientific studies have found no association between autism and the MMR vaccine or thimerosal (a mercury-based preservative previously used in some vaccines). A 1998 study erroneously linking vaccines to autism was found to be an intentional fraud.
Too Many Too Soon: The recommended vaccine schedule is carefully designed by pediatric vaccine experts to provide synergistic benefits and ensure optimal protection from disease during the period infants and young children are most vulnerable. Delay or avoidance of vaccines has been found to put children directly in harm’s way of preventable diseases without safety benefits.
Ingredient Safety: Components of vaccines like thimerosal, aluminum, and formaldehyde are included in very small quantities and have not been shown to cause harm except in rare cases of allergy or hypersensitivity. They help prolong the vaccine’s shelf life and effectiveness. The benefits of vaccination far outweigh any theoretical risks from vaccine components.
Herd Immunity: Benefits Beyond Individuals
Vaccination is also important from a public health perspective. The more individuals vaccinated within a community, the less opportunity there is for a disease to spread from person to person. This indirect protection is known as “herd immunity” and it also helps protect people who are unable to receive certain vaccinations, such as newborn babies, the elderly or those with certain medical conditions. Low vaccination rates increase risks of disease outbreaks affecting whole communities. Globally, estimated deaths from vaccine-preventable diseases fell from an estimated five million in 1980 to 1.5 million in 2018 largely due to herd immunity from vaccines.
In Conclusion: Benefits Greatly Outweigh Risks
Overall, decades of research among millions of individuals unequivocally establishes that vaccines are very safe and effective for preventing dangerous infectious diseases. While some risks of severe allergic reactions or other potential side effects exist, these risks are exceedingly low compared to the dangers of not vaccinating. In consultation with your child’s pediatrician, maintaining recommended vaccination schedules provides a safe and effective means of protecting all children from preventable and sometimes deadly diseases. Well-funded disinformation campaigns that distort vaccine science and discourage vaccination should be recognized as a serious threat to public health.
