A boosting skin vaccination with a biodegradable microneedle patch and protein constructed from sequences of influenza virus subtypes could improve the effectiveness of conventional influenza vaccines, according to a study.
The World Health Organization's decision to downgrade the influenza drug Tamiflu on its essential medicines list is better late than never, but still comes far too late, argues an expert in a new article.
The scientific textbook depiction of the flu virus is about to get a facelift, due to a new discovery that a model of the influenza genome architecture untouched since the 1970s isn't so perfect after all. The finding could give scientists the opportunity to better predict pandemics and find new ways to disrupt the flu virus.
Zika virus can cause severe brain damage in people infected before birth. A new study in mice shows that females vaccinated before pregnancy and infected with Zika virus while pregnant bear pups who show no trace of the virus. The findings offer the first evidence that an effective vaccine administered prior to pregnancy can protect vulnerable fetuses from Zika infection and resulting injury.
A protein that is activated by viruses, including influenza, rhinovirus (the common cold), dengue and HIV, has now been identified by researchers. Once activated, it suppresses the body's key antiviral reaction. This study also investigated a prototype drug to treat these debilitating viral diseases.
Vaccines to combat a virus that can lead to fatal lung infections are urgently needed to help prevent child deaths worldwide, research suggests. Experts report that more than 115,000 children under five are dying each year from complications associated with the infection, called Respiratory Syncytial Virus (RSV). Around three million are admitted to hospital each year with the virus, which causes breathing difficulties and wheezing.
By developing a new technique for labeling the gene segments of influenza viruses, researchers now know more about how influenza viruses enter the cell and establish cell co-infections – a major contributing factor to potential pandemic development.
