A class of viruses known to cause severe diarrheal diseases – including the one famous for widespread outbreaks on cruise ships – can grow in the salivary glands of mice and spread through their saliva, scientists at...
Dr Malick Gibani explains how a human challenge study for non-typhoidal Salmonella can support vaccine development and protect vulnerable populations. Salmonella infection (salmonellosis) is a common disease caused by...
One of the best-known aspects of the Covid-19 pandemic is that the virus ‘jumped’ into people from animals – perhaps bats or pangolins – in a process known as zoonotic transfer. What hasn’t been clear to scientists is...
A collaborative study from UT Southwestern scientists has identified a new function for a protein called TAO2 that appears to be key to inhibiting replication of the influenza virus, which sickens millions of...

When the COVID-19 vaccine first became available, people eagerly signed up for coveted slots to boost their antibodies against the virus that shut down much of the world. But not everyone who rolled up their sleeve...
Emory University is participating in a Phase I clinical trial to evaluate the use of messenger RNA (mRNA) technology in HIV vaccines for the first time in humans. The trial, IAVI G002, was launched earlier this year by...
Inhaled aerosol vaccines provide far better protection and stronger immunity than nasal sprays, McMaster scientists who compared respiratory vaccine-delivery systems have confirmed. While nasal sprays reach primarily...
