Fewer Shots, Greater Protection: How 6-in-1 Vaccines are Reshaping Infant Healthcare
The landscape of infant vaccinations is undergoing a significant shift, with 6-in-1 combination vaccines like ‘Hexasim’ gaining prominence. These vaccines, now included in national immunization programs (NIP), are streamlining the vaccination process, reducing the burden on both infants and parents, and potentially saving healthcare systems substantial costs.
The Rise of Combination Vaccines
Traditionally, protecting infants required multiple individual vaccinations or combinations of vaccines. ‘Hexasim’, developed by Sanofi, consolidates protection against six diseases – diphtheria, tetanus, pertussis (whooping cough), polio, Haemophilus influenzae type b (Hib), and hepatitis B – into a single injection. This represents a move from a 5-vaccine approach, requiring additional shots for hepatitis B.
According to recent findings, the adoption of 6-in-1 vaccines like ‘Hexasim’ can lead to an estimated 12 billion won (approximately $9.2 million USD) in socioeconomic cost savings domestically.
Reduced Injection Burden and Improved Compliance
The most immediate benefit is a reduction in the number of injections. Previously, infants required six vaccinations to cover these diseases; now, with ‘Hexasim’, that number is reduced to four after the initial hepatitis B shot. This decrease in injection frequency addresses a key concern for parents and caregivers, making the vaccination schedule more manageable.
“Many parents are anxious about multiple injections at once,” explains Dr. Jo Hye-gyeong, a pediatrician at Ewha Mokdong Hospital. “Reducing the number of shots increases the likelihood of timely vaccination and reduces the demand to catch up on missed doses.”
Enhanced Convenience and Safety
‘Hexasim’ likewise offers logistical advantages for healthcare providers. Unlike older 5-in-1 vaccines that required mixing a powder and liquid solution before administration, ‘Hexasim’ is a pre-filled syringe containing a liquid formulation. This eliminates the mixing step, reducing the risk of contamination and saving valuable time.
Currently, over 90% of clinics and hospitals are reportedly utilizing 6-in-1 vaccines as their primary method of immunization, indicating a rapid and widespread adoption within the medical community.
Navigating New Vaccine Landscapes
The introduction of new vaccines, such as those for RSV (respiratory syncytial virus), adds complexity to the immunization schedule. However, the reduced injection burden from 6-in-1 vaccines can assist mitigate concerns about vaccine overload and improve overall acceptance of preventative measures.
Protecting Against B형간염 (Hepatitis B): A Critical Focus
Recent changes in vaccination recommendations in other countries, such as the United States CDC’s reconsideration of newborn hepatitis B vaccination, have raised concerns. Dr. Jo Hye-gyeong emphasizes the importance of maintaining universal hepatitis B vaccination for newborns in Korea, citing the higher prevalence of infection compared to Western countries. She stresses that vaccination remains the most effective way to protect infants from this potentially chronic and life-threatening disease.
“Newborn hepatitis B vaccination is a crucial preventative measure, especially given the difficulty in determining a mother’s infection status,” Dr. Jo states. “Hepatitis B can lead to chronic illness, making vaccination a highly valuable intervention.”
The Importance of Reliable Information
With the proliferation of information online, particularly through social media, Dr. Jo cautions against relying on unverified sources. She urges parents to consult with pediatricians and rely on scientifically sound information when making decisions about their child’s health.
