Insights

Influenza vaccine coverage remains low in children, with only 35.1% fully vaccinated. Improving parental understanding of influenza and its vaccine is key to increasing pediatric vaccination rates.

Area of Science:

  • Pediatric infectious diseases
  • Vaccinology
  • Public health

Background:

  • Severe influenza cases are reported annually in unvaccinated infants and children, despite health authority recommendations.
  • Influenza vaccination is crucial for pediatric populations to prevent severe illness.

Purpose of the Study:

  • To investigate influenza vaccine coverage among pediatric patients.
  • To identify predictive factors associated with influenza vaccination status in children.

Main Methods:

  • A cross-sectional survey was conducted with parents of pediatric patients (aged 6 months to 17 years) at a Hong Kong outpatient clinic.
  • Questionnaires assessed child's vaccination status, parental understanding, beliefs about influenza, and vaccine perceptions.
  • Backward logistic regression analysis identified factors influencing influenza vaccine uptake.

Main Results:

  • Full vaccination was achieved by 35.1% of the 405 pediatric patients studied.
  • Positive vaccination status was linked to "very good" parental understanding of influenza and its vaccine (aOR, 6.7).
  • Other predictors included children with chronic conditions and "high" cues to action (aOR, 5.7), and "high" perceived susceptibility to influenza (aOR, 4.8).

Conclusions:

  • The study highlights low influenza vaccine coverage in the pediatric population.
  • Targeted interventions to enhance parental knowledge and understanding of influenza vaccination are recommended.
  • Improving parental awareness may significantly increase future pediatric vaccine uptake.

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
