Get the original essayVaccines: “Vaccines are dead cells that are introduced into the body with the aim of killing microbes or adding immunity to the body against a particular disease. » Role of vaccines in developing immunity: Vaccines increase immunity in a body. against infection. Sometimes these types of infections are not fatal and do not even cause illness, but they do not present any type of symptoms. Therefore, when vaccines are injected, some imitated vaccines show symptoms. When the infection spreads, memory develops by T cells against this disease in a body for the future. However, vaccines did not immunize the body immediately after injection. It may take several days to become immune after receiving the vaccines. By vaccination you are immunized against different diseases. If someone is not vaccinated this can also pose a risk to others, as they are able to spread the disease to others. A risk of epidemic may develop. An outbreak is a cluster of cases of a particular disease within a community. Epidemics caused by unvaccinated individuals are becoming more and more common. For example, today in Pakistan (December 2017 and January 2018), swine flu is spreading in different cities. Five people died from the flu virus because they were not vaccinated against the swine flu/flu virus. Seasonal flu outbreak saw in Multan and Lahore and 23 lives claimed 47 patients in total. Types of Vaccines: There are different types of vaccines There are several types of vaccines used. These are whole organism vaccinesPurified macromolecules as vaccinesRecombinant vaccineDNA vaccinesMultivalent subunit vaccinesDescription: Vaccines have different types as well as different advantages and some disadvantages.1: Attenuated vaccines: This type of vaccines is used to increase immunity and is made up of virulent microorganisms whose effectiveness is reduced to virulence. These vaccines are activated (live). Advantages: It is a low cost vaccine. It provides immunity quickly and instantly.Disadvantages:1. The virus can spread and cause disease.2: Inactivated vaccine: Killed microorganisms make this vaccine and their effectiveness is totally reduced due to virulence. These are killed cells of the microorganism, which are used in inactivated vaccines. They give the body immunity against pathogenic attacks. .Advantages:1. No spread of the virus and did not cause disease.Disadvantages:They produce a weak response unlike live vaccines.An adjuvant is required to initiate their activity or proper functioning.3:Toxoid vaccine:As the name suggests , it is made from a poison which secretes different pathogens. This poison is rendered harmless but can cure the disease. They also do not cause illness, but can sometimes cause side effects to strengthen the immune system.4: Conjugate vaccines: These are composed of strong and weak antigen binding by covalent bonds to increase the effectiveness of a lower antigen.Advantages:1. This vaccine has a very important property, namely vaccination safety or safety, because it did not cause any harmful diseases or side effects like live attenuated vaccination. Disadvantages: As this vaccine is manufactured by a."
