Cancer Vaccines01:30

Cancer Vaccines

383
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...

Subviral Agents01:29

Subviral Agents

20
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Development of Immunocompetence01:22

Development of Immunocompetence

320
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

957
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

4.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Summary

A new vaccine strategy bundle significantly boosted human papillomavirus (HPV) vaccine initiation and completion rates in adolescents with sickle cell disease (SCD). This cancer prevention effort improved vaccination coverage in a specialty clinic setting.

Area of Science:

  • Oncology
  • Immunology
  • Pediatrics

Background:

  • Adolescents with sickle cell disease (SCD) are at increased risk for HPV-related cancers.
  • Low human papillomavirus (HPV) vaccine uptake is a challenge in specialty clinics.

Purpose of the Study:

  • To assess a vaccine strategy bundle's effectiveness in increasing HPV vaccine initiation and completion.
  • To improve cancer prevention for adolescents with SCD.

Main Methods:

  • A Hematology clinic implemented an 15-month intervention (Oct 2018-Dec 2019).
  • The strategy included staff education, provider incentives, in-clinic vaccine administration, and chart verification.
  • Nearly 500 adolescents with SCD were included in the study.

Main Results:

  • HPV vaccine initiation increased from 28% to 46%.
  • HPV vaccine completion rose from 7% to 49%.
  • Completion was linked to proximity to healthcare, lower deprivation, and higher hospitalizations.

Conclusions:

  • The implemented strategy successfully enhanced HPV vaccine completion rates in adolescents with SCD.
  • The initiative underscored the importance of cancer prevention for individuals with SCD.
  • Ongoing education for staff, patients, and families is crucial.
