Vaccination is a simple, safe and effective way to protect against diseases before a person comes into contact with them.
You won't get sick from the vaccine itself, but some people may have a reaction to it, such as pain (or swelling) at the injection site or even a slight fever. Vaccination uses the body's natural defense mechanisms to build resistance to a range of infectious diseases and makes your immune system stronger. This is why vaccines are such a powerful way to combat various diseases: they do not cure the disease, but prevent its development.
The invention of vaccination is considered one of the most ambitious achievements in medicine; it is thanks to vaccination, according to WHO, that the death of 2-3 million people can be prevented annually. Like any medical product, a vaccine may not be absolutely safe, but the benefits of its use significantly outweigh the possible risks (severe course of the disease, various complications, death). Immunization has made many infectious diseases quite rare, and some of them have even become forgotten. For example, diseases such as diphtheria, measles, tetanus, whooping cough, and polio, which were very common just a generation ago, are becoming rare.
Sometimes the path to victory over a particular disease lasts many decades; scientists take years to develop new vaccines, but in the context of a pandemic and with the active cooperation of scientists from different countries under the auspices of the WHO, this has become possible in a much shorter period of time.
The success of the vaccination program depends on the willingness of each person to contribute to the well-being of all.You shouldn’t expect people around you to stop the spread of diseases; each of us must also do our best.
