|April 18, 2018
Summary
The World Health Organization (WHO) updated its typhoid vaccine recommendations, emphasizing new typhoid conjugate vaccines for disease control. This guidance supports global immunization programs and public health policy.
Area of Science:
- Public Health
- Vaccinology
- Infectious Disease Epidemiology
Background:
- Typhoid fever remains a significant global public health concern, necessitating updated vaccination strategies.
- Previous World Health Organization (WHO) guidelines on typhoid vaccines were established in 2008.
- The emergence of new typhoid conjugate vaccines requires updated recommendations for their effective use.
Purpose of the Study:
- To present the WHO's current recommendations on the use of typhoid vaccines, including novel typhoid conjugate vaccines.
- To update and replace the 2008 WHO position paper on typhoid vaccines.
- To provide guidance to Member States on health policy matters related to typhoid vaccination.
Main Methods:
- Review and synthesis of scientific evidence on typhoid vaccines.
- Development of evidence-to-recommendation tables.
- Expert consultation through the Strategic Advisory Group of Experts (SAGE).
Main Results:
- The 2018 WHO position paper provides updated recommendations for typhoid vaccine use.
- Emphasis is placed on the importance of vaccination for typhoid fever control.
- Recommendations include guidance on a new generation of typhoid conjugate vaccines.
Conclusions:
- Vaccination is crucial for controlling typhoid fever globally.
- The updated WHO recommendations aim to guide large-scale immunization programs.
- New typhoid conjugate vaccines represent a significant advancement in typhoid prevention efforts.

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...

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Position and Displacement
26.8K
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

Serial Position Effect
563
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

Position Vectors
2.0K
A position vector is a fundamental concept in mathematics that helps determine the position of one point with respect to another point in space. It is a vector that describes the direction and distance between two points. Position vectors are highly useful in the field of math and science, as they help represent spatial relationships and make calculations easier.
For instance, we want to locate a point P(x, y, z) relative to the origin of coordinates O. In that case, we can define a position...
