[EFFECTIVENESS OF PREVENTIVE VACCINE PROPHYLAXIS OF CHICKEN POX IN MILITARY COLLECTIVES]
Zhurnal Mikrobiologii, Epidemiologii I Immunobiologii
|August 12, 2015
Summary
Preventive vaccination against chickenpox significantly reduced disease incidence in military personnel by 86%. While effective in minimizing spread, vaccination does not completely eliminate chickenpox from military collectives.
Area of Science:
- Immunology
- Preventive Medicine
- Epidemiology
Context:
- Military collectives are susceptible to infectious disease outbreaks.
- Chickenpox (varicella) poses a risk to population health and operational readiness.
Purpose:
- To evaluate the effectiveness of a preventive varicella vaccine prophylaxis in military settings.
- To assess both epidemiological and immunological outcomes of vaccination.
Summary:
- A study involving 200 vaccinated and 97 unvaccinated servicemen in a chickenpox outbreak showed a significant reduction in disease incidence.
- Vaccination demonstrated 86% epidemiological effectiveness, with only 2 cases per thousand in the vaccinated group versus 72 per thousand in the unvaccinated group.
- Immunological effectiveness ranged from 42% to 44%, with mild local reactions in 10% and systemic reactions in 1.7% of vaccinated individuals. No post-vaccinal complications were observed.
Impact:
- Vaccination effectively minimizes chickenpox spread within military populations.
- Preventive vaccination is a valuable tool for controlling infectious diseases in closed communities.
- While not a complete elimination strategy, vaccination significantly enhances disease control and reduces outbreaks.

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...

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:

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.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
