Antigens Involved in Adaptive Immunity

803
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Cancer Vaccines01:30

Cancer Vaccines

570
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...

Pharmacovigilance01:19

Pharmacovigilance

1.2K
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Active versus Passive Immunity01:31

Active versus Passive Immunity

6.7K
Immunity, along with the ability to limit pathogen growth to prevent significant body tissue damage, can be gained either by (1) actively developing an immune response within the individual after exposure to a pathogen or after getting vaccinated or (2) passively transferring immune components from an immune individual to one who is nonimmune. Both these forms of immunity can be found naturally and in medical practices.
Active Immunity
Active immunity refers to the resistance one develops...

Area of Science:

  • Public Health
  • Behavioral Science
  • Vaccinology

Background:

  • Achieving widespread COVID-19 vaccination is crucial for pandemic control.
  • Vaccine mandates are considered to boost vaccination rates.
  • Potential negative psychological effects of mandates require investigation.

Purpose of the Study:

  • To examine individual preferences for mandatory versus voluntary COVID-19 vaccination policies.
  • To identify detrimental effects associated with mandatory vaccination policies.
  • To explore interventions that could mitigate negative consequences of mandates.

Main Methods:

  • Cross-sectional surveys and two preregistered experiments were conducted in Germany and the US.
  • Participant data (N=4629) were analyzed to assess correlates of policy preferences and mandate effects.
  • Investigated reactance and its impact on vaccination intentions and adherence to protective measures.

Main Results:

  • Mandates can elicit reactance, a psychological response to perceived threats to freedom.
  • Reactance negatively impacts vaccination intentions, including for influenza vaccines.
  • Adherence to COVID-19 protective measures may also decrease due to mandate-induced reactance.

Conclusions:

  • Mandatory vaccination policies, while intended to increase uptake, may have unintended negative consequences.
  • Understanding and mitigating psychological reactance is essential for effective public health strategies.
  • Future policies should consider behavioral science insights to balance public health goals with individual autonomy.
