Abstract

For a long time, society has suffered from communicable diseases, which, for centuries, killed millions of people due to the lack of advanced technology in treatments and, mainly, immunization. From the 18th century to the present day, there have been many advances and discoveries with regard to vaccination, contributing to innumerable diseases being prevented and even eradicated, improving the quality of life of the population. To analyze, through a narrative review, the chronological development, from the beginning to the present day, of the discoveries and advances regarding the field of immunization vaccines, as well as the impact of this on the quality of life of the population of the Brazil and the world. Through a bibliographic inspection of the literature, articles published in the last 20 years were selected, operating the SCIELO and PUBMED platforms as databases, addressing the keywords "update", "vaccination"," Immunization" and "technological innovation" in portuguese and english, adopting patterns of exclusion and inclusion, thus selecting the articles to be used in the present study. After centuries of advances and discoveries in the field of immunization technology, with the creation of campaigns and vaccination programs, such as the National Immunization Program, in Brazil, of international reference, in the year 2021 it was observed, with the incidence of the Covid-19 pandemic, which has plagued the world, the emergence of demand for the formulation of vaccines against this agent, corroborating the importance of this technology and announcing the new challenges to be overcome. The production of vaccines in the 21st century is the result of hard investments, made for years, in technologies and research, aiming at the improvement in the stoning and amplification of the demands for immunogens, which increase, more and more, the quality of life of the population. Vaccines are an undoubted instrument for the conservation and development of the population's health process. The advances in this technology, as well as the expansion of investments in it, are extremely necessary when it comes to overcoming the challenges that arise every day with regard to communicable and immunopreventable diseases.
