. Design a Live attenuated vaccine to limit the pathogenicity of Mycobacterium leprae
The only licensed TB vaccine, bacillus Calmette Guérin (BCG), is a live attenuated vaccine derived from Mycobacterium bovis.In addition, BCG vaccination offers little to no protection against pulmonary TB, cannot eliminate latent M. tuberculosis, and is ineffective at preventing subsequent TB.Multidrug therapy uses combinations of antibiotics that kill M.leprae including: dapsone, rifampin, clofazamine, fluoroquinolones, azithromycin, and minocycline. Antibiotics must be taken regularly until treatment is complete due to the fact M. leprae has the ability to grow back.A preventive measure of M. leprae is to avoid close contact with infectious people who are untreated

Martin received a killed (inactivated) polio vaccine. Had he received a live attenuated polio vaccine instead, he would have developed poliomyelitis. Fortunately, Martin escaped being given any live vaccines before he was diagnosed. In many countries (not the U.S.), infants are universally given Bacillus Calmette-Guerin (BCG), an attenuated (weakened) form of the tuberculosis bacteria, which provides partial protection against tuberculosis infection. BCG incites a cell-mediated immune response and after received it, infants become tuberculin-positive (which means they show a hypersensitivity...

1 pts D Question 2 Explain how the bacterium is attenuated in the Vivotif vaccine and why this attenuation prevents the the bacteria in the vaccine from causing typhoid fever. (Note: You will find the answer in the product insert for the drug under "Clinical Pharmacology." Be specific and thorough in your response.) HTML Editor? ? , Paragraph o words
Scientists at the University
of Iowa are working on a live, genetically COVID-19 vaccine. They
have inserted the genes that encode COVID-19 envelop protein a
virus (parainfluenza). In the diagram, 1) viral vector vaccine.
Parainfluenza virus causes mild influenza-like
symptoms.
Diagram or explain the steps that were taken to get the
COVID RNA into the parainfluenza host. Remember to make the
parainfluenza virus non-pathogenic.
How can Pfizer scale up production of the genetically
engineered parainfluenza virus to produce quantities enough...
4. Rank the following vaccine types from most protective to least protective. Explain the rankings. Then explain how each type of vaccine is made, and give an example of each. Inactivated whole-cell vaccine Live attenuated vaccine Polysaccharide vaccine Polysaccharide-protein conjugate vaccine Toxoid vaccine 5. The word "allergy is often used colloquially to describe immune hvpersensitivity reactions
Which type of viral vaccine is likely to produce the most diverse adaptive immune response? A) live attenuated virus. B) inactivated/killed virus. C) purified viral protein.

Critical Thinking 1. What problems are associated with the use of live attenuated vaccines? 2. Many of the serological tests require a supply of antibodies against pathogens. For example, to test for Salmonella, anti- Salmonella antibodies are mixed with the unknown bacterium. How are these antibodies obtained? 3. A test for antibodies against Treponema pallidum uses the antigen cardiolipin and the patient's serum (suspected of having antibodies). Why do the antibodies react with cardio- lipin? What is the disease?
BRV-PV is a live virus vaccine that replicates to some extent. How might you use genetic engineering to make a safer rotavirus vaccine? Note: the virus capsid is composed of 4 different proteins.
