Vaccine

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.

Whooping cough cases rise sharply across the United States

Pertussis, also known as whooping cough, is a vaccination-preventable illness that has been on the rise in the United States. Following a several-year lull during the pandemic, cases of whooping cough rose sixfold in 2024 and remain high.

HPV vaccination reduces risk of vulvar and vaginal lesions

Girls who are vaccinated against HPV are not only well protected against cervical cancer; they are also less likely to develop severe precancerous lesions of the vulva and vagina, particularly if they were vaccinated before the age of 17.

New nanoparticle vaccines show promise against multiple deadly filoviruses

Filoviruses get their name from the Latin word "filum," meaning thread-a reference to their long, filamentous shape. This virus family contains some of the most dangerous pathogens known to science, including Ebola, Sudan, Bundibugyo and Marburg viruses.

Researchers develop antibody to combat HCMV, a common, overlooked virus

Researchers at Texas Biologics have made an important discovery that could improve treatment of human cytomegalovirus (HCMV), a common but overlooked virus that poses serious risks to vulnerable populations, including people with compromised immune systems. According to the Centers for Disease Control and Prevention, the virus is the most infectious cause of birth defects in the United States.

Targeted mRNA vaccines train the immune system to destroy cancer cells

No matter where cancer cells grow in the human body, they are a threat to our health and our lives. But instead of treating them with chemotherapy or radiation - which have undesirable side effects - what if we could train our own immune systems to kill the rogue cells?
