Current polio vaccines have been successful in nearly eradicating polio in the world. Unfortunately, there have been emerging cases of polio in recent years. To combat this, scientists have designed a new oral poliovirus vaccine that could result in a new and safer polio vaccine. Continue reading Redesigning the polio vaccine – Lessons from evolution
Nerve agents are toxic chemicals that disrupt signals in the nervous system. They can be absorbed easily through skin contact or by breathing. Exposure to nerve agents interferes with nerve cell signaling and prevents muscles from relaxing, quickly leading to muscle paralysis and eventually death by asphyxiation or cardiac arrest. Treatment is possible but must be administered within minutes of exposure. No long-term vaccine or … Continue reading Nano-antidote provides long-term protection against nerve agents
Infectious diseases — including HIV, tuberculosis, and malaria — are a leading cause of death worldwide, particularly in low income countries and among young children. A new study found that the vaccines aimed to prevent many of the world’s most deadly diseases may not be developed any time soon. The study, funded by the Gates Foundation and the Swiss Agency for Development and Cooperation, focused on 538 … Continue reading Vaccines for World’s Most Deadly Infectious Diseases Unlikely
by Catherine Weiner figures by Rebecca Senft Every winter, as we avoid the sneezing stranger on the sidewalk and the coughing coworker in the coffee room, the same thought races through our heads: “I hope it’s not the flu.” This year, the United States has been hit with a devastating flu season. As of March 17th, the Centers for Disease Control and Prevention (CDC) recorded … Continue reading Hit Me with the Flu Shot: Why you need the flu shot every year
It’s the middle of February and flu season is in full swing. Perhaps you’ve already experienced the body aches, fever, and fatigue that signal the influenza virus. However, there is a chance that these same symptoms were not caused by the flu. A family of viruses called adenovirus is also making the rounds and resembles the flu. The adenovirus kills significantly fewer people than the … Continue reading Achoo! Is Adenovirus making you sick this winter?
by Fernanda Ferreira figures by Brad Wierbowski Every day 140 Americans die from an opioid overdose. To confront the crisis, not only must opioid addiction treatment become more readily available, but new and improved forms of treatment must also be developed. Dr. Carl Alving, whose life work has been to develop an HIV vaccine, never planned on investigating novel systems for treating opioid addiction. But … Continue reading Can We Treat Heroin Addiction and HIV with a Single Vaccine?
Growing up, every child is familiar with the pain of a seasonal flu shot. However, there is still a chance to catch the flu even with the shot, due to the flu virus’s high variability and adaptability. The major issue with flu vaccine production is a long production time. Using traditional methods, it usually takes 4-6 months for a vaccine to be generated against a particular flu strain, … Continue reading New weapon combating flu – caterpillar-grown vaccine
2016 was a tumultuous year in many respects, but it ended with a major victory against Ebola hemorrhagic fever. Ebola’s most recent outbreak ravaged West Africa from 2013 to 2016, killing roughly two out of every five patients and tens of thousands of people in total. Treatment options are limited once the disease takes hold, so researchers have been pursuing a vaccine that protects against … Continue reading Virus Beware: Ebola Vaccine Successfully Developed
