Abstract

Children younger than 2 years of age with previous invasive Haemophilus influenzae (Hib) type b disease may not develop protective antibodies to antigens of Hib and may be at risk of developing a second episode of Hib disease. Twenty-three children with prior Hib disease were immunized with Haemophilus b conjugate vaccine (meningococcal protein conjugate). Children 12 to 24 months of age were given one dose of vaccine and children younger than 12 months of age were given 2 doses 2 months apart. Antibody to the polysaccharide capsule of Hib (PRP) was measured by radioimmunoassay. Eighteen children had preimmunization serum antibody concentrations less than 0.150 micrograms/ml. All 18 children responded with greater than 0.150 micrograms/ml of antibody after a single dose of vaccine. Only 1 of the 23 children had a preimmunization serum antibody concentration greater than 1.000 micrograms/ml. Seventeen children ultimately responded with greater than 1.000 micrograms/ml of antibody (P less than 0.0001), concentrations of antibody thought to correlate with protection. Haemophilus b conjugate vaccine (meningococcal protein conjugate) is immunogenic in children with invasive Hib disease. Children younger than 2 years of age with inva...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
