Cervical cancer vaccine. What is it and how does it work?


Antibodies and immune cells in our body attack vital fragments of the composition of the bacterium or virus, without which they cannot live. But some of these fragments are not harmful to humans.

Based on this phenomenon, scientists have developed the concept behind a vaccine.
We introduce into the body substances from the microbial composition that are not pathogenic to humans, but are vital to the microbe. These substances will not cause the disease, but will provoke an immune response from the body (specialized antibodies and cells). When the real microbe attacks our body, the antibodies and immune cells recognize the substances in its composition and destroy them. This destroys the microbe.
Substances from which vaccines are manufactured are obtained from true microbes through different biochemical processes. They are not dangerous to the body. Therefore, when we are injected, we do not get sick. Our body makes antibodies and immune cells that are ready to destroy the substances in the vaccine, that is, the same substances found in microbes.
Vaccines offer the body immunity to the species of microbes from which they are manufactured. Many vaccines are mandatory at certain ages, starting with the first days after birth. Other vaccines are optional and can be made on request or at the doctor's recommendation when we increase our risk of being exposed to certain pathogenic germs. For example, when winter comes (the flu vaccine), when we make trips to areas of the globe characterized by other microbes than those with which we are used (typhoid fever, hepatitis A vaccine, etc.).
Why do we need vaccines?
Vaccines are needed when there are serious diseases that affect a large part of the population. In terms of cervical cancer, Romania ranks 1st in Europe. In our country, cervical cancer is the second leading cause of cancer death affecting women.
Through vaccination, many diseases that in the past made millions of victims, were substantially reduced or eradicated: measles, diphtheria, tuberculosis, tetanus, rubella, polio, epidemic parotiditis, various infections with meningococcus, pneumococcus, streptococcus, which can cause very serious meningitis. or that can especially affect the lungs.
Vaccines have made the health of the world's population grow. I am a known progress of humanity and I am a success in the fight against diseases. However, whenever a new one appeared, there were voices rising against him. This fact has a positive aspect because in this way the beneficial qualities of the drug are kept under control.
But vaccines, although well purified and carefully prepared, are not miracles. Sometimes accidents can occur when administering them, because each organism is different and reacts differently to the vaccine. Therefore, they are administered under medical supervision. Adverse reactions to vaccines rarely occur and usually disappear within a few days.
The fact that some people have adverse reactions to it does not mean that the vaccine is not good or effective. Absolutely all vaccines and all medicines can in some cases cause side effects; as well, some foods, even if they are healthy.
Vaccines are specially designed to ward off infections. At present they are part of our life and we can consider ourselves lucky for this reason.
The first vaccine was discovered by doctors in 1796 against the disease called smallpox. At that time the pharmaceutical techniques were rudimentary and it had to last many years until the vaccine could be given to the population.
Smallpox, a very serious infectious disease, has made hundreds of millions of victims throughout history. It sounds incredible, but it's true! At present this disease no longer exists; was completely eradicated with the help of the vaccine.
