Vaccine helps to prevent ill-health and death from infectious pathogens. From birth we are constantly exposed to different bacteria, viruses and other pathogens. Most are not harmful, many may be beneficial but some are capable of causing disease, vaccines have greatly reduced or eliminated many infectious diseases that one routinely kills or harms infects, children and adults. However, the viruses and bacteria that cause these diseases still exist and you can still get these diseases if you aren't vaccinated.
The body's immune system helps protect us against infectious diseases. When we are exposed to infection, the immune system triggers a series of responses to neutralize the microbes and limit their harm through various lines of defense. Exposure to an infectious disease often gives lifelong protections when we are exposed to the same disease.
Vaccine work with your body's natural defenses to help you safely develop immunity to disease, this lowers your risk of getting certain diseases and suffering from their complications such as hepatitis; tuberculosis vaccines lower risk of lung damage and lung cancer while yellow fever vaccines lower the risks of liver and kidney problems.
REASONS YOU SHOULD GET VACCINATED
Vaccine helps to keep you health: the Centers For Disease Control and Prevention( CDC) recommended vaccinations throughout your life to protect money against infections, skipping vaccine makes you vulnerable to different type of illnesses
Vaccines are important to your overall health, as diet, and exercise, like eating a clean meal, exercising regularly and getting regular medical checkups. Vaccines play a key role in keeping you healthy.
Vaccines are safe: vaccines are one of the most convenient and safest preventive care, all vaccines undergo long and careful review by scientists, doctors and the federal government to make sure they are safe. Although there are potential side effects associated with vaccines that are uncommon and much less severe than the disease they prevent.
Vaccines don't cause the disease that they are made to prevent, vaccines are either made from killed or weakened viruses, making it impossible to contract the disease from the vaccine.
Vaccines prevent the transmission of infections from your family, co-worker and friends. For example, adults are the most common source of pertussis ( whooping cough) infection in infants which can be deadly for babies. When you are Vaccinated you are protecting yourself, family, co-worker who may not be Vaccinated of the disease.
If children aren't vaccinated, they can spread disease to other children who are too young to be Vaccinated or to people with weakened immunity, such as transplant recipients and people with cancer. This could result in long term complications and even death for those vulnerable people.
SIGNIFICANCE OF VACCINATION
Reduction In Infectious Disease Morbidity and Mortality: The most significant impact of vaccines Is to prevent morbidity and mortality rate from serious infections that disproportionately affect children. Vaccines are estimated to prevent almost millions of deaths and to save 386 million and 96 million disability adjustments in a year.
Eradication of Infectious Diseases: this is the permanent reduction of disease to zero of the global incidences of infection caused by specific agents as a result of deliberate efforts. vaccination can achieve in eradication of global transmissible disease by presenting certain features, such as low incidence of inapparent forms, existence of a single stable pathogen, interhuman transmission involving no vector and availability of an effective well-tolerated low cost vaccine
Herd Immunity: This is an indirect form of protection from infectious disease that can occur with some diseases when a sufficient amount of a population has become immune to an infection through previous vaccination or infection. Thereby reducing the likelihood of infection for individuals who lack immunity, who may be too young, too vulnerable or too immunosuppressed to receive vaccine, when individuals are immune they are unlikely to contribute to disease transmission in a community. This can be reached when enough people have recovered or have been vaccinated against a disease and have developed protective antibodies against future infection.
Reduction in Secondary Infectious That Complicate Vaccine Preventable Disease: vaccine can prevent disease beyond the specific infection they are designed to target. Infection with pathogens, in particular viruses, can predispose to the acquisition of other bacterial infections, for example influenza virus infection both seasonal and pandemic, is frequently complicated by bacterial pneumonia and acute otitis media.
Prevention of Cancer: vaccines were developed against severe infections with major morbidity and mortality from acute disease. Non communicable diseases including cancer, become the most frequent causes of death in industrialized countries and developing countries.
Preventing Antibiotic Resistance: the rise in antimicrobial resistance (AMR) is a universal major threat. The use of antibiotics in humans exposes the bacteria that reside in our microbiota to selection pressures resulting in the development of antimicrobial resistance. As the bacteria constituting the host microbiota are frequently responsible for invasion of diseases such as pneumonia, urinary tract, abdominal infections, The risk of developing infections that are difficult to treat is fast becoming a reality. Vaccination is crucial in mitigating the risk of diseases by preventing people from developing viral and bacterial infections and therefore reducing the antibiotic burden to which their microbiota are exposed, also children and elderly who are at particular risk of infection can benefit from vaccines against common primary and secondary infection such as pneumonia, influenza, measles, typhoid fever.
Getting immunized costs less than getting treated for the diseases that the shots protect you from.
