NewsNew design strategy expands nanoparticle vaccine approach to influenza viruses
Research scientists have developed a blueprint for stabilizing key influenza proteins and using them to make next-generation vaccine candidates.

NewsA natural molecule present in the human body protects against the flu
A research team has demonstrated that dermcidin, an antimicrobial peptide produced constitutively by the human body, also exhibits antiviral activity against the influenza virus. People who do not develop flu-like symptoms have higher baseline levels of this molecule.

NewsTargeting two flu proteins sharply reduces airborne spread
A study in ferrets — which have remarkably similar respiratory systems to humans — suggests that immunity to two proteins in the H1N1 influenza virus sharply reduces transmission.

NewsStudy: Experimental bird flu vaccine excels in animal models
A vaccine has demonstrated complete protection in mice against a deadly variant of the virus that causes bird flu. It focuses on the H5N1 variant known as 2.3.4.4b, which has caused widespread outbreaks in wild birds and poultry.

NewsMutation could facilitate H5N1 bird flu virus infection and potential transmission in humans
A recent study reveals that a single mutation in the H5N1 bird flu virus that has recently infected dairy cows in the U.S. could enhance the virus’ ability to attach to human cells, potentially increasing the risk of passing from person to person.

NewsInfluenza viruses can use two ways to infect cells, study finds
Scientists have discovered that certain human flu viruses and avian flu viruses can use a second entry pathway, a protein complex of the immune system, to infect cells, helping the viruses to infect different species.

NewsA new viral target could help combat the global measles resurgence
A multinational research team has identified a novel way to attack measles, paving the way for new vaccines and antiviral drugs that could help combat the virus’s global resurgence.

NewsDrug-like inhibitor shows promise in preventing flu
Scientists have developed a potential drug-like molecule that blocks the first stage of type A influenza infection.

NewsNew strategy could lead to universal, long-lasting flu shot
Researchers have opened a new avenue in the attack against influenza viruses by creating a vaccine that encourages the immune system to target a portion of the virus surface that is less variable.
