As medical science progresses and medicines and surgical techniques become progressively more sophisticated, their impact on the patient and society at large becomes less predictable and, at the same time, more impressive, where they are successful. In turning to modern medicine for solutions to their health problems, people are usually satisfied with the response that they receive. However, there remain certain illnesses which cannot be cured, and these are typically caused by pathogens known as viruses. Vaccine formulation development is an essential process in trying to counter viruses and their spread.
The standard response nowadays to infection is to resort to an antibiotic. However, viruses do not respond to these, because they are not biotic organisms. Technically, they are not alive, so antibiotic measures are useless in trying to eliminate them. Surgery and other procedures, such as radiation, are equally non-applicable. The only sure measure is a vaccine.
A vaccine partially imitates the virus in the patient's body, so that the person's immune system starts to manufacture viral antibodies. The body does this in response to the detected threat of the pseudo-virus (the vaccine).
These antibodies are only manufactured by the human immune system. They entirely eliminate the viral particles. Once the infection has been destroyed, though, the antibodies remain in the system indefinitely, preventing any future recurrence of that specific virus. By using immunization, life-long immunity is therefore generated without authentic infection taking place.
The process of the immunization of infants and young kids is based on this principle. They are typically immunized against common yet serious diseases like measles and polio. Immunization has become a standard practice, yet it is necessary. Smallpox and polio, two supposedly archaic names, used to be substantial threats to public health and maimed, disfigured or killed many people.
Some of the most serious diseases are viral in nature, such as the notorious Ebola, AIDS, viral meningitis (which sets in within 48 hours and has terrible symptoms), and, as stated above, polio. These are all potentially lethal infections. The development of vaccines to counter them is thus of extreme importance.
A virus may re-surface in a medication-resistant form in time. This happens if it is able to mutate into an unknown form, or one against which the antibodies in the patient are not effective. This may sound extreme or unlikely, but it happens every year with the influenza virus, which is why there is no viable vaccine for flu, or for the common cold, either. These viruses simply mutate too quickly and cannot be permanently countered.
Ultimately, people should realize that a vaccine is only part of the solution to public infection and epidemics. If they are to be safe, people should also try to exercise sound personal health habits. Many illnesses, such as AIDS, can be prevented through basic practical precautions, and relying on science to produce cures is not always an option or even sensible.
