Insights

Pediatric vaccine uptake and coverage declined during the COVID-19 pandemic, with some age groups showing persistent or worsening reductions even during reopening. Strategies are needed to improve immunization rates and prevent disease outbreaks.

Area of Science:

  • Public Health
  • Epidemiology
  • Pediatrics

Background:

  • Vaccination coverage is crucial for preventing vaccine-preventable diseases.
  • The impact of the COVID-19 pandemic on pediatric vaccination during the reopening phase was previously unevaluated.

Purpose of the Study:

  • To assess the impact of the COVID-19 pandemic on vaccination coverage in children aged 0-18 years.
  • To compare vaccine uptake during prepandemic, stay-at-home, and reopening periods in 2020 versus 2019.

Main Methods:

  • A large cohort of Southern California children (0-18 years) was analyzed.
  • Vaccine uptake and coverage for recommended and measles-containing vaccines were compared between 2020 and 2019, across different pandemic phases.

Main Results:

  • Total and measles-containing vaccine uptake decreased significantly in 2020 compared to 2019, though it recovered in younger children (0-23 months).
  • Measles-containing vaccine uptake recovered in older children (2-18 years), but overall vaccine uptake remained lower.
  • Vaccination coverage declined and remained reduced for most children ≤24 months, while older children saw decreased coverage during the reopening period.

Conclusions:

  • Pediatric vaccine uptake and coverage significantly decreased during the pandemic, with persistent or worsened reductions in several age groups during reopening.
  • Strategies like immunization tracking, reminders, and recalls, especially during virtual visits, are essential to improve vaccine uptake and prevent outbreaks.

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...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

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: 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...

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...
