COVID-19 is a pandemic of unprecedented proportions in recent human history. There have been around 200 million confirmed cases and four million fatalities worldwide in less than 18 months since the pandemic began. Additionally, a great deal of work has gone into finding vaccines that are both safe and effective. By July 2021, 184 COVID-19 vaccine candidates were in pre-clinical development, 105 were in clinical development, and 18 had received emergency use approval from at least one regulatory body. These vaccines include the whole virus live-attenuated or inactivated, protein-based, viral vector, and nucleic acid vaccines. Three billion COVID-19 vaccine doses were given around the world by the middle of 2021, primarily in high-income nations. However, in some countries such as Iran, new vaccines have been produced and even exported to others. The most famous Iranian Covid-19 Vaccine brands are COVIran Barekat, PastoCovac, Spikogen, Razi, and Fakhra which all the, have more than 80% efficiency according to recent research and national statistics and have been welcomed by the people themselves. The way these vaccines work is different, for example, the technology of production of the Barekat vaccine is based on an inactivated vaccine. In other words, "this vaccine is made from the coronavirus, which is weakened or killed by chemicals, which is similar to how the polio vaccine is immunized, nevertheless, Spikogen contains a protein from a virus that has been genetically engineered. The vaccine contains a recombinant protein called spike (similar to the spike protein on the surface of the virus) and is produced with the adjuvant (a substance that increases the effectiveness of the vaccine) to increase its effectiveness. Overall, before the summer of 2022, about 150 million doses of vaccines, both Iranian and foreign, have been injected into Iran. In this speech, we are going to talk about the types of COVID 19 vaccines produced in Iran, their effectiveness, and specifications.
