WHAT IS COVID:
Germs are all around us, both in our environment and in our bodies. When an individual is susceptible and they encounter a harmful organism, it can lead to disease, or in some cases, death.When a pathogen does infect the body, our body’s defense, called the immune system, is triggered and pathogens are attacked, destroyed or overcome.
Coronavirus disease (COVID-19) is an infectious disease caused by the SARS-CoV-2 virus.
THE BODIES NATURAL RESPONSE:
Bacteria, viruses, parasites, or funguses that can infect the body and cause disease are known as pathogens. Each infection has numerous subunits that are particular to that pathogen and the sickness it produces. An antigen is a component of a pathogen that causes the production of antibodies. The immune system relies heavily on antibodies produced in reaction to the pathogen's antigen. Antibodies can be thought of as troops in the body's defense mechanism. Our system's antibodies, or soldiers, have been taught to recognize a single antigen. Our bodies contain thousands of different antibodies. The immune system takes time to respond to when the human body is exposed to an antigen for the first time. In the meantime, the person is susceptible to becoming ill. Antigen-specific antibodies are created and act with the rest of the immune system to eliminate the infection and stop the sickness from spreading. When the body makes such antibodies in response to an antigen, it also generates memory cells producing antibodies, which continue even after the pathogen has been vanquished by the antibodies. Because the memory cells are ready to pump out antibodies against this kind of antigen, if a person is exposed to the dangerous pathogen in the future, their immune system will be able to respond immediately and efficiently, protecting against disease.
HOW VACCINES HELP:
Vaccines contain weak or deactivated components of a certain organism (antigen) that cause the body to respond with an immune reaction. Instead of the antigen itself, newer vaccinations incorporate the template for generating antigens. This deteriorated copy will not cause disease in the recipient of the vaccine, regardless of whether the vaccine is made up of the antigen itself or the blueprint for the body to create the antigen, but it will encourage the immune system to react much like it would on first ever reaction to the real pathogen. Some vaccinations need repeated doses administered within a certain time period apart. This is occasionally intended to allow for such creation of long-lasting antibodies and memory cell development. Throughout this approach, the body is educated to resist illness organisms and store pathogenic memory so that it can fight it quickly if and when re-exposure occurs in the long term.
WHAT IS HERD IMMUNITY:
When a person gets immunized, they are almost certainly protected against the specific illness. However, not everyone will be immunized. People who have underlying health disorders that impair their body's immune system, or who have severe sensitivities to particular vaccine components would be unable to receive certain immunizations. These persons still can be safeguarded if they reside among vaccinated individuals. When a large number of individuals in a society are immunized, the virus has a difficult time spreading since most of the individuals it meets are protected. The more often others are vaccinated, the less likely people who cannot be protected by the vaccine will be exposed to harmful pathogens. This is known as herd immunity. This is especially important for people who are not only unvaccinated but also susceptible to illnesses that are vaccinated. A single vaccine does not provide 100% protective effect, and herd immunity cannot completely prevent people who cannot be safely vaccinated. However, with herd immunity, these people will enjoy significant protection thanks to the surrounding vaccinations.
So, vaccinating not only protects yourself, but also protects those in the community who are unable to be vaccinated. If you are able to, get vaccinated.
