Never before have we heard people talk both in the media and in our daily lives about vaccines, the types of vaccines, and the big pharmaceutical companies and laboratories that develop them. Even so, exposed as we are to so much information, it is not easy to get a clear idea about how each of those that have reached the market and that are currently being administered to the population work. What do all Covid-19 vaccines have in common? The answer is simple. Regardless of whether vaccines are of one type or another, they all help our body develop immunity against the virus that causes the disease by generating, on the one hand, antibodies that recognize and fight it, and on the other, memory cells. The latter will quickly notify our body that it has encountered the same virus again, in which case antibodies will be produced again to attack it. To date, one of the great unknowns that is being studied is how long these memory cells can protect us against the virus. There are different types of vaccines currently approved (and in use) and others that are in the later stages of clinical trials. In fact, it is the first time that so many vaccine candidates are being developed simultaneously against the same disease. ![]() There are different methods of making vaccines. The most traditional use the whole virus, either inactivated or attenuated (such as polio and measles, respectively) or fragments of it (such as whooping cough). There are other slightly more novel methods, in which a harmless empty virus (viral vector) is used that carries either genes that express proteins or parts of proteins that belong to the virus against which it is intended to create immunity. This last type includes the first vaccines approved for use in humans, the so-called messenger RNA (mRNA) vaccines, which are those from Pfizer-BioNTech and Moderna.īoth vaccines are quite similar since they both contain the information necessary to synthesize the main antigen of the coronavirus, which is the spike protein (S), which is found on the surface of the virus.Īnd other completely new methods such as those that incorporate encapsulation of the genetic material that contains the instructions for making virus-specific proteins.
