Current Status of Malaria Vaccinology In order to assess the current status of malaria vaccinology one must first take an overview of the whole of the whole disease. One must understand the disease and its enormity on a global basis. Malaria is a protozoan disease of which over 150 million cases are reported per annum. In tropical Africa alone more than 1 million children under the age of fourteen die each year from Malaria. From these figures it is easy to see that eradication of this disease

Discuss innate and acquired immunity and how they are demonstrated by the mother-infant relationship. The human body is amazing. The Immune System’s main job is to protect the body from infection. It does this in Two major ways: innate immune system and the adaptive or acquired immune system. In the innate immune system innate immunity is developed similar to an army to fight nonspecific organisms and is always armed and ready to serve the human body against the first signs of infection.

Ricin is a toxic protein found in castor oil plant seeds. The toxicity of Ricin has been known for centuries and was even used by the KGB government to assassinate Georgi Markov‚ a famous journalist who openly criticized the Soviet Union’s communist regime. The toxicity of ricin is caused by its ability to deactivate ribosomes and halt protein synthesis. Therefore‚ Ricin is categorized as a ribosome inactivating protein (RIP). There are two types of RIPs: type I and type II. Type I RIPs are usually

Sydenham’s chorea (SC) is a major neurological manifestation of acute rheumatic fever (ARF) caused by group A β-haemolytic streptococci (GABHS). It occurs mainly in children between 5-15 years‚ with a female predominance‚ occurring at a ratio of approximately 2:1 (Oosterveer Overweg-Pladsoen & Roos 2010). Typically occurring 2-6 months after infection with GABHS‚ SC is characterized by uncoordinated‚ involuntary movements‚ muscle weakness and hypotonia. Psychiatric symptoms‚ including depression

The technical term for the eating of a cell is phagocytosis‚ so eosinophils are said to phagocytize complexes formed between antigens and antibodies. Lymphocytes kill cells that contain viruses. Lymphocytes scan the body looking for viruses. There are two types of lymphocytes: B cells and T cells. T cells

The major function of B cells is the production of antibodies in response to foreign proteins of bacteria‚ viruses‚ and tumour cells. B cells search for antigen matching its receptors and when it finds such antigen it connects to it and a triggering signal inside of the B cell is set off. Once the B cell receives

It has saved millions of lives over the years and prevented hundreds of millions of cases of disease. There are many legitimate concerns about vaccines safety from parents. Questions arise if vaccines should be state mandated without the choice from parents. Ethically speaking‚ parents need to be aware on

They include the activation of CD8+ T lymphocytes‚ implicated in host defense against intracellular pathogens via cytotoxic T lymphocytes (CTL)‚ and CD4+ T lymphocytes‚ which secrete cytokines and play a role in B cell production of specific antibodies (Figure 1). Despite its potential impact on protective immunity‚ however‚ DNA vaccination is not always successful. Protective immunity depends mostly on the immunogenicity of a pathogen’s antigen‚ but other factors such as the frequency and route

Artificially acquired active immunity results from the administration of a killed or weakened microorganism or toxoid.
