What is a vaccine?

A Vaccine is a normally injectable preparation of the attenuated virus. The virus is injected into the bloodstream directly so that when attenuated it does not cause the disease to occur but it generates an answer in the immune system by creating the necessary defenses against the "strain" inoculated thus preventing the organism from future infections .

What diseases have been eradicated?

Thanks to the vaccines humanity has managed to eradicate the smallpox. It has also significantly diminished the appearance of other diseases such as polio, measles, chicken pox and typhoid fever.

Vaccination schedule.

According to the World Health Organization, these calendars relate to the legislation that each country applies to its fellow citizens. There are vaccines that are already available from an early age so babies are protected against certain diseases. Older people are given a dose of memory to strengthen the immune system. At the same time, there are vaccine schedules for the elderly, where we can find, for example, flu vaccination that is done in a seasonal fashion during the winter season.
