Why Vaccine Formulation Development Is Important

By Stacey Burt

The science of modern medicine may appear as sophisticated and technologically advanced to outside observers, and some techniques and pharmacological interventions lead to unstable outcomes or are difficult to forecast. Many patients are successfully treated by them. Yet there remain those illnesses which cannot be treated at all, and a significant proportion of the latter are the result of infection by what are known as viruses. The main imperative in approaching an untreatable virus is vaccine formulation development.

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.

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 the natural reaction to the viral infection. The immune system manufactures them in response to the virus' presence, and only the human body is able to do this. After the infection has been eliminated, the antibodies remain in the system, preventing relapses for the rest of the person's life. This is why vaccination has the potential to bring about permanent resistance (or immunity) to a specific virus.

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 very serious illnesses are caused by viruses, such as AIDS, Ebola, one of the two forms of meningitis, and, as mentioned previously, polio. All of these illnesses can cause permanent negative outcomes or even death. Trying to develop a vaccine to treat them is therefore an important activity in modern medicine, and one which sometimes enjoys attention in the media.

Over time, however, a virus may mutate and return to a medication-resistant state. It either mutates into a new genetic form (strain), or simply develops resistance against the patient's antibodies. As frightening as this may sound, it is an ongoing phenomenon, as seen, for example, in the case of the influenza virus, which presents in a new strain every year. There is no immunization process against it because it mutates too quickly.

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.
