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.
Unlike other pathogens, a virus cannot be destroyed by an antibiotic, since, technically it is not alive (i. E. Biotic in nature). Also, it is a germ, so it cannot be eliminated through mechanical techniques such as surgery or ultrasound. The only effective known intervention is a vaccine.
The principle behind a vaccine is extremely simple. It is similar to the virus in question, so it elicits the same response in the patient's body, but it does not have the same serious or lethal outcome. It therefore causes the body to start producing antibodies, once the immune system has registered that the virus-like particles are in the system.
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.
This permanent resistance is the reason why young kids are vaccinated against certain obvious, common diseases, such as polio or measles. Once immunized, people remain safe fort he rest of their lives, since the antibodies are always present. Even extremely mundane, seemingly innocuous illnesses, such as smallpox, were immense threats to public health in the past and the introduction of effective vaccines was the main step in removing them from society.
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.
