The manufacture of a vaccine is a complex process whose development requires between four and seven years. During this time, a series of tests are carried out, first in the laboratory; Next, if these are favorable, tests are carried out on humans; They confirm the effectiveness, stability and safety of the vaccine, gradually increasing the number of participants. At the beginning of writing this book, the European Medicines Agency had authorized the marketing of four Covid -19 vaccines (BioNTech/Pfizer, Moderna, AstraZeneca and Janssen). A few months later, Novavax, Valneva and Sanofi Pasteur joined the company. On March 30, 2023, Hipra approves.


Thus, as of the printing date of the publication of the book "Covid 19: Drugs and excipients of vaccines" (April 10, 2023), there are eight vaccines authorized in just over three years since the WHO declared the pandemic due to Covid-19 (March 11, 2020). The efforts of the scientific community in seeking a solution to a global public health problem have allowed the development of a medicine in an unprecedented time.
