Varicella vaccine effective on chicken pox; Impact on herpes zoster unclear

07.02.2005


The varicella vaccine is almost 90 percent effective against chickenpox, but its impact on herpes zoster (shingles) is unknown and needs wider surveillance, Yale School of Medicine researchers write in today’s New England Journal of Medicine (NEJM) perspective section.



The varicella virus causes both chickenpox and herpes zoster, which occurs when a latent virus in the brain becomes reactivated and causes a painful rash on the skin, leading to severe pain and burning along nerves. Zoster affects people with compromised immune systems, such as the elderly. Since 1995, when the varicella vaccine was first introduced in the United States, it has greatly reduced the number of chickenpox cases and deaths from varicella. The vaccine may also have a key role in preventing zoster.

"Even though it has been shown that varicella vaccine has had a major impact on the epidemiology of chickenpox in the U.S., we do not know what impact, if any, the widespread use of varicella vaccine will have on the epidemiology of herpes zoster or shingles--its incidence, age distribution and severity," said Marietta Vazquez, M.D., an author on the article and assistant professor in the Department of Pediatrics at Yale School of Medicine.


Referring to a study in the same issue, Vazquez and co–author Eugene D. Shapiro, M.D., professor in the Departments of Pediatrics and Epidemiology and Public Health at Yale, note that the study shows a significant decline of 66 percent in mortality due to varicella. "These findings are relevant because they emphasize the importance of continuing the varicella vaccination program," said Vazquez. "It is possible that varicella vaccine may be useful in helping prevent zoster if it is administered to elderly persons who have had chickenpox. The long–term effects of universal vaccination on both chickenpox and zoster need to be assessed so that the vaccine policy can be modified, if necessary."

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
