Scientist says research indicates need for effective HPV vaccine for women and men and a simple HPV screening test

A call to explore a broader use of HPV (human papillomavirus) vaccines and the validation of a simple oral screening test for HPV-caused oral cancers are reported in two studies by a Johns Hopkins Kimmel Cancer Center investigator.

Minor shift in vaccine schedule has potential to reduce infant illness, death

A new study by researchers at Wake Forest University School of Medicine and Vanderbilt University suggests that protecting infants from a common, highly contagious and even deadly disease may be as easy as administering a routine vaccine two weeks earlier than it is typically given.

Researchers develop DNA vaccine for West Nile virus

Researchers are developing a DNA-based vaccine against the dreaded West Nile virus (WNV), which can be transmitted from animals to humans. The unique feature of this vaccine is that it is also effective after onset of the disease, for it has therapeutic properties.

Persistent bacterial infection exploits killing machinery of immune cells

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

Flu shot protects kids - even with a suboptimal vaccine match

Children who receive all recommended flu vaccine doses are less likely to catch the respiratory virus that the CDC estimates hospitalizes 20,000 children under 5 years old every year.

Experts say it is very important for all children to receive flu vaccinations

According to new research from the U.S., experts have found it is very important for all children to receive flu vaccinations for themselves and for the people around them.

Important steps towards the development of a human vaccine against malaria

Every day 2,000 children die from malaria in Africa alone. The infection is transmitted from human to human by biting mosquitoes and remains one of the world's most devastating diseases. Despite many years of effort a vaccine is still not available but is urgently needed, if we are to make an impact on this enormous problem.

By imaging live cells, researchers show how hepatitis C replicates

The hepatitis C virus is a prolific replicator, able to produce up to a trillion particles per day in an infected person by hijacking liver cells in which to build up its viral replication machinery.

Gene against bacterial attack unravelled

Dutch researcher Joost Wiersinga from AMC Medical Centre in Amsterdam has unravelled a genetic defence mechanism against the lethal bacteria Burkholderia pseudomallei. The research is the next step towards a vaccine against this bacterium suitable for bioweapons.

New tuberculosis vaccine safer, more effective than BCG vaccine for HIV-positive people

A new tuberculosis vaccine could be safer and more effective than the currently available BCG vaccine, particularly for HIV-positive people, according to a study to be published in the November issue of Infection and Immunity, IANS/Times of India reports (IANS/Times of India, 10/24).

Respiratory syncytial virus may hide in the lungs, lead to asthma

Conventional wisdom has been that respiratory syncytial virus (RSV) - a common virus that causes infection in the lungs - comes and goes in children without any long lasting impact.

Vaccinating new mothers and other family members against influenza offers important flu protection to newborns

Vaccinating new mothers and other family members against influenza before their newborns leave the hospital creates a "cocooning effect" that may shelter unprotected children from the flu, a virus that can be life-threatening to infants, according to researchers at Duke Children's Hospital.

Gardasil safety questioned, CDC urged to back up statement with data

The National Vaccine Information Center (NVIC) is calling on the Centers for Disease Control (CDC) and Food and Drug Administration (FDA) to publicly release the study design, data and names of principal investigators involved in a statement this week maintaining that Gardasil vaccine is safe with no serious side effects.

High dose flu vaccine boosts immune response in elderly

Giving people age 65 and older a dose four times larger than the standard flu vaccine boosts the amount of antibodies in their blood to levels considered protective against the flu, more so than the standard flu vaccine does. The findings from a study of nearly 4,000 people were presented Oct. 26 at a national meeting on infectious diseases.

New molecules with many branches will help unleash potential of nanotechnology

Materials science and the pharmaceutical industry could soon be revolutionized by emerging nanotechnologies based on designer molecules with long complex tree-and branch structures. Such molecules offer almost limitless scope for design of bespoke compounds for specific applications in disease therapy, for novel materials such as resins, as well as electronic displays, and energy storage. Almost every field involving design and synthesis of chemical compounds will be transformed by the arrival of technologies allowing nanoscale design of these branched molecules, known as hyperbranched polymers.

Exposure to low doses of mercury changes the way the arteries work

An international team of researchers has shown that mercury is another important factor in cardiovascular disease as it changes the way arteries work. One of the possible sources of exposure of humans to mercury is by eating contaminated fish.

Ministers urged to rethink rather than repackage $2 billion global response to infectious diseases

As the first globally co-ordinated plan for the planet's gravest health threats is hatched by government ministers from around the world this weekend, a new report sets out a 10-point plan for this new, globalised approach to infectious diseases such as avian flu.

Getting the flu early may protect against worse one later

New evidence about the worldwide influenza pandemic of 1918-1919 indicates that getting the flu early protected many people against a second deadlier wave, an article co-authored by an NIH epidemiologist concludes.

Universal vaccine could protect people and pets from deadly flu pandemics

A single vaccine could be used to protect chickens, cats and humans against deadly flu pandemics, according to an article published in the November issue of the Journal of General Virology. The vaccine protects birds and mammals against different flu strains and can even be given to birds while they are still in their eggs, allowing the mass vaccination of wild birds.
