Not only does a push for a chickenpox vaccine protect a child and his or her classmates, it can also protect grandparents who may not have had chickenpox. Protecting the elderly is also the idea behind another vaccination that many of us line up for each winter: the flu shot. Between 12,...
" says Dr. Schaffner. "If scientists can make a killed vaccine that is effective, that is what they will do. It's all about trial and error." Most viral diseases, he says, require live-attenuated vaccines, but the vast majority of bacterial illnesses are prevented with inactivated vaccines...
he US Centers for Disease Control and Prevention (CDC) recommends that all newborn infants receive the Hepatitis B (HepB) vaccine, typically administered on the very first day of their lives. It does so despite the fact that the vast majority of children born in the US are not at signific...
Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract disease in young children and elderly people. Although the virus was isolated in 1955, an effective RSV vaccine has not been developed, and the only licensed intervention is passive immunoprophylaxis of high-risk infant...
But wading through the many varieties and requirements is a bit like walking through a maze: How long is a yellow fever vaccine good for? How many vaccines can be given at once? What are the shots needed for Thailand? How much are vaccinations?
What is Hep A? Hepatitis A (HAV) is a contagious, acute (sudden and severe at the start) liver disease that, unlike hepatitis B and C, does not become chronic (gradually developing serious, long-term complications). Hepatitis A is a virus, and its infections can be mild and last a fe...
20–30% of people with long-term persistent hepatitis C infection are known to suffer from liver cirrhosis, out of which 1% of people develop HCC [34,35]. Since 1982 HBV vaccine has been available and is helping lower the prevalence of chronic infection and HCC, but there is no available...
might be had a need to make advanced prediction of lifespan and therefore accelerate lifespan scientific studies. Highly delicate and specific frailty-based predictive endpoint requirements for aged mice remain elusive. While frailty-based prediction falls quick as a surrogate for lifespan, it did ...
The infectious nature of the disease had already been recognized in the early days of medical microbiology, in 1885 by Lürmann during an “icterus epidemic” which occurred after a small pox vaccination campaign. The vaccine had been made from human “lymph” (probably obtained from the vaccine...
Long-term co-infection of liver cells (hepatocytes) with HBV and HDV can be established in a highly scalable cell culture system. Image shown is of the cell culture 28 days after HBV/HDV co-infection, with hepatocyte nuclei in blue, a Hepatitis B viral protein in red, and HDV genomic RN...
