Busting Vaccine Myths: Children’s Immunity Not ‘Overwhelmed’ by Immunization

There’s a popular misconception suggesting child immunization, through vaccines, could ‘overwhelm’ the infant immunity. This notion misses an important understanding of how our body system operates. In 2025, the U.S. Centers for Disease Control and Prevention came into the focus of a lawsuit, with claims broadening around the institution’s apparent lapse in assessing the overall safety impacts of its recommended 72-dose immunization protocol for children.

Despite the gravity of these allegations, no concrete evidence has emerged in court to substantiate the charges. As it stands, scientific research presents compelling arguments affirming the safety of the vaccine regimen proposed by the CDC. Around August 2025, social and digital media were rife with assertions raising doubts about the CDC’s endorsed immunization schedule for children.

These sweeping charges claimed the institution’s immunization protocol contravened constitutional and federal laws. However, as the situation remains, none of these accusations have been well-established or validated in any court proceeding to date. The CDC remained unresponsive to inquiries probing the credibility of the lawsuit’s charges.

The vaccine regime for children up to the age of 18, as recommended by the CDC, comprised approximately 72 doses, tallying annual flu shots. Consistent research has pointed to the innate capacity of infant immunity to healthily manage and adapt to routine vaccinations. Health experts have repeatedly underscored vaccines as ‘among the most efficacious and safe preventative healthcare measures against grave illnesses and mortality’.

Like any healthcare intervention, immunization carries its own risks and the possibility of serious, albeit rare, adverse effects. However, the medical and scientific community share a near-unanimous agreement over the health benefits of vaccines greatly overshadowing their potential risks. The lawsuit, however, launched in the U.S. District Court for the District of Columbia, forwarded allegations that ‘a comprehensive study on the cumulative effects or potential risks of the CDC’s childhood vaccine schedule has never been undertaken’.

It’s important to understand that the CDC’s childhood immunization strategy originates from the Advisory Committee on Immunization Practices (ACIP). This committee’s recommendations are classified into categories A and B. Category A entails blanket recommendations for all children within a specific age bracket, whereas category B vaccines are administered based on individual evaluation and decision-making by clinicians.

At the time of writing this, most vaccines in the childhood immunization schedule fell under Category A. ACIP guidelines, in essence, don’t have statutory legal enforceability. However, ACIP advisories often find a place in state legislation. An interesting development happened in June when Health and Human Services Secretary Robert F. Kennedy Jr., known for his anti-vaccine stance, overhauled the entire advisory committee.

Moreover, several of the newly appointed panel members have been associated with skepticism regarding vaccines in the past. Numerous academic studies and exhaustive assessments have suggested that the human immune system has the strength to manage a large volume of immunizations.

In particular, a thorough study of the immunization schedule by the National Academy of Medicine (formerly known as the Institute of Medicine) in 2013 revealed ‘no serious safety concerns associated with abiding by the childhood immunization schedule’. Correspondingly, the National Academy of Medicine in 2002 concluded that an infant’s immune system is ‘intrinsically designed to manage the antigen load introduced through regular immunization’.

Therefore, though a federal lawsuit did level allegations against the CDC, accusing it of unseriousness in evaluating the safety of the recommended childhood vaccine schedule, respected figures in the scientific community and substantial data pointed to an alternative story. This underlines that an infant’s immune system is indeed resilient and perfectly capable of adjusting effectively to a substantial number of vaccinations.
