¿Qué pasa con aquellas enfermedades para las cuales aún no hay vacunas?
GalinKa [24]

Answer:

In diseases that still do not have vaccines, humans would have to be much more careful not to have an injury, since vaccines are a way of having antibodies against microorganisms so that we can survive or better defend ourselves against them.

Vaccines are active acquired immunity, this means that a person who is vaccinated acquires new defenses that are manufactured by their own body, that are not vaccinated or that the vaccine does not exist are diseases that could potentiate with the life of the human being or trigger symptoms graves

Explanation:

People who are not vaccinated or suffer from pathologies that do not have vaccines do not have antibodies to fight the microorganism in the first infection, therefore the pathology develops in a much more serious, harmful and even lethal way.

Antibodies are proteins that our body manufactures by inoculating DNA structures, proteins, inactive bacteria, etc. in the form of a vaccine, these proteins are the method of recognition of said microorganism.

Thus generating that once the microorganism enters the body after the vaccine has been placed, it is recognized and eliminated.All this process written simply in the previous text happens in vaccinated people, in those who do not have the vaccine or are not vaccinated. suffer the opposite consequences for lack or deficit of acquired immunity.

Vaccination is a form of active acquired immunization and each country has a different vaccination plan according to the pathologies that prevail in the area to protect the population that lives in them.
