Vaccine News and Research RSS Feed - Vaccine News and Research

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

New study estimates overall prevalence of genital HPV infection among men in the U.S.

Human papillomavirus (HPV) infection is the most common sexually transmitted infection in the United States, as well as a cause of various cancers, and a new study published online by JAMA Oncology estimates the overall prevalence of genital HPV infection in men ages 18 to 59. [More]
First symptoms of meningitis

First symptoms of meningitis

Thankfully, meningitis is a rare condition. Although it can occur in anyone, it's more prevalent in babies and young children, with young people and students being the next most at risk group. In the early stages, it can be very difficult to tell meningitis apart from milder diseases, as it often resembles other common viral illnesses. Symptoms of the disease can develop very quickly.

Vaccines are an important part of routine healthcare for adults, seniors and women who are pregnant. [More]
Vaccine campaign targeting freshers could hold key to reducing spread of meningitis

Vaccine campaign targeting freshers could hold key to reducing spread of meningitis

A campaign targeted at students arriving at university for the first time could hold the key to reducing the spread of meningitis and septicaemia, say researchers at the universities of Nottingham and Leicester. [More]
New study identifies cost-effective way to reduce death due to rabies

New study identifies cost-effective way to reduce death due to rabies

Every year in India, 20,000 people are estimated to die from rabies. Most of the victims are children. Nearly all of the deaths occur after victims are bitten by rabid dogs. For years, experts have debated the best strategy to reduce this burden. [More]
Penn Vet researchers identify potential target to fight against Ebola

Penn Vet researchers identify potential target to fight against Ebola

Viruses and their hosts are in a eternal game of one-upmanship. If a host cell evolves a way to stop a virus from spreading, the virus will look for a new path. And so on and so forth. [More]
S. pneumoniae uses hosts' immune defenses to spread infection, study reveals

S. pneumoniae uses hosts' immune defenses to spread infection, study reveals

The bacteria that cause most cases of pneumonia worldwide secrete a toxin that helps them jump from one body to the next - with help from the hosts' immune defenses. This is the finding of a study led by researchers from NYU Langone Medical Center and published online January 11 in Cell Host & Microbe. [More]
