Summary
Vaccination failure, where disease occurs post-immunization, can stem from vaccine issues or improper vaccination. Standardized definitions are crucial for evaluating vaccine benefits and public health impact.
Area of Science:
- Immunology
- Public Health
- Vaccinology
Background:
- Global immunization programs show success, but vaccines are not always 100% effective.
- Vaccination failure, defined as disease occurrence post-vaccination, can happen despite successful immunization efforts.
Purpose of the Study:
- To propose general definitions for types of vaccination failure.
- To establish universally accepted concepts for assessing vaccine efficacy and effectiveness.
Main Methods:
- Literature review and expert consensus on vaccination failure.
- Development of a general framework for defining vaccination failure categories.
Main Results:
- Distinguishes between actual vaccine failure and failure in vaccination process.
- Proposes general definitions applicable across various vaccines.
Conclusions:
- Standardized definitions of vaccination failure are necessary for accurate assessment of vaccine performance.
- Future work should include vaccine-specific definitions based on public health needs.

Overview
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 type of...
Hypothesis: Accept or Fail to Reject?
The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null hypothesis and 'fail to...

Vaccine Production
Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...
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...

Immunological Memory
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...
