Summary Introduction
To determine:
The reason for the inability of scientists to produce vaccine against
Introduction:
Many organisms attack other organisms and cause infectious diseases. All organisms have a well-defined organ system that fights with these pathogens and protect the body from infectious diseases. This organ system is called the immune system. The scientists have discovered a technique in which microbes are used to enhance the immune system. This method is termed as vaccination. The substance that contains weak or attenuated form of microbes to enhance the activity of immune system is termed as vaccine.

Please answer with 500 wordsarrow_forwardVaccines typically contain particles that are pieces of the virus or bacteria they target. How do you think this helps you avoid getting sick in the future? a) vaccine-preventable diseases are just part of life. it is better to have the disease than become immune through vaccines b) vaccine programs fail to produce overall health benefits of a population by because they do not reduce the transmission od disease c) the particles act as antibodies, against which the person's immune system will develop antibodies d) the particles act as antigens, against which the person's immune system will develop antibodies e) vaccines create an entirely new immune systemarrow_forward

A) reversion to virulent strain that causes disease B) ineffectiveness because it’s not “the real thing” C) contamination with other viruses or bacteria D) the capacity to induce shock in recipientsarrow_forwardWhy do scientists worry more about new strains of viruses like influenza and coronviruses as potential causes of deadly human pandemics, but they never talk about the next big Herpesvirus strain deadly pandemic? Which of the statements below helps partially answer that? We already have effective vaccines for Herpes. Influenza and CoV have more genes, more complex gene expression, and can undergo genetic recombination or reassortment, while Herpesviruses are more limited. Only humans get Herpesviruses, while animals can get Influenza viruses and Coronaviruses. dsDNA viruses aren't very transmissible and even when they are, they're not deadly. Influenza and CoV are RNA viruses which results in having higher mutation rates -- they can more easily jump between host species. Herpesviruses are dsDNA viruses and usually very host specific.
