  Dengue vaccine is a human vaccine that prevents dengue disease. The necessity to produce immunisation against all four dengue serotypes hampered the development of dengue vaccines, which began in the 1920s. Only dengue seropositive persons aged 9–45 years in dengue endemic areas are eligible to get this vaccination. It's given subcutaneously in a three-dose sequence spaced six months apart (0, 6, 12 months). Dengue vaccine  will be more complicated than measles or mumps vaccines: Dengue fever is caused by four viruses that are related but not the same. They vary in antigenicity, implying that any vaccine you produce must protect against not one, but four viruses. DENV-1, DENV-2, DENV-3, and DENV-4 are the four dengue virus serotypes. They are members of the Flavivirus genus and family Flaviviridae (of which the yellow fever virus is the type species), which includes about 53 viruses. Dengue fever can hit you repeatedly. Dengue fever can be contracted not once, twice, or eve...

  Artificial blood is a cutting-edge transfusion medicine idea in which specially made chemicals replace allogenic human blood transfusion by transporting and delivering oxygen throughout the body. RBCs from expired human blood, cow blood, hemoglobin-producing genetically modified microorganisms, or human placentas are frequently used to make artificial blood in dark red or burgundy colours. The artificial haemoglobin molecules have been engineered to form a strong structure and to function without the RBCS protective coating. A blood substitute (also known as artificial blood or blood surrogate) is a substance that looks and operates like genuine blood. Hemoglobin-based oxygen carriers (HBOC) and perfluorocarbon-based oxygen carriers are the two main types of "oxygen-carrying" blood replacements being researched (PFBOC). Artificial blood Market Is it possible to make artificial blood? Artificial blood can be made in a variety of techniques, including synthetic manufa...
