Summary
Same-day adolescent vaccination is effective and efficient. However, missed opportunities for concomitant vaccination, especially for the HPV vaccine, persist, particularly among boys and older teens.
Area of Science:
- Public Health
- Vaccinology
- Epidemiology
Background:
- Concomitant (same-day) vaccine delivery in adolescents is safe, effective, and efficient.
- Improving vaccination coverage for recommended adolescent vaccines can be achieved by increasing same-day vaccine administration.
- Little is known about the demographic and socioeconomic factors influencing concomitant adolescent vaccination.
Purpose of the Study:
- To identify correlates of concomitant vaccination among adolescents receiving tetanus, diphtheria, and acellular pertussis (Tdap) booster, meningococcal conjugate (MenACWY), and human papillomavirus (HPV) vaccines.
- To examine trends in concomitant vaccination over time.
- To identify specific adolescent and household characteristics associated with receiving multiple vaccines on the same day.
Main Methods:
- Analysis of healthcare provider-verified records from 70,144 adolescents (aged 13-17 years) in the National Immunization Survey-Teen (2008-2012).
- Multivariable logistic regression was used to identify correlates of concomitant versus single vaccination, stratified by adolescent sex.
- Vaccination data spanned 2007-2012, with data collection and analysis in subsequent years.
Main Results:
- Concomitant vaccination rates varied by sex, with 51%-65% of girls and 25%-53% of boys receiving two vaccines simultaneously.
- Concomitant vaccine uptake generally increased over survey years, except for HPV vaccination in boys.
- Vaccination concurrently was less common with increasing age, in the Northeast region, for girls with highly educated mothers, and for boys in metropolitan areas.
Conclusions:
- Significant opportunities for concomitant adolescent vaccination are being missed, particularly for the HPV vaccine.
- Targeted interventions are needed to address groups with low rates of same-day vaccination.
- Improving concomitant vaccination practices can enhance population-level coverage of essential adolescent vaccines.

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the...

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

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...

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

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...
