The coronavirus came as a real shock to me. Some of my friends died in just a couple of weeks. It was a real shock for me. Moreover, I had to radically change my lifestyle and find a remote job. Fortunately, many countries have already invented vaccines so that I can choose the best option.
 But which Covid vaccine is best to pick? For me, this question was not obvious. To begin with, I want to say that there are about 5-7 companies that provide injections. Some of them claim that two doses are enough. However, other companies recommend 3-4 doses.  I will not advertise to any manufacturers and want to focus only on the types of vaccines. Initially, scientists were able to create a so-called "dead" version of the virus. Then, your body receives a deactivated strain and learns to resist foreign cells. Adenovirus vector vaccine is like a guide for your body and contains a neutralized virus.   By the way, there is a third type, and these are mRNA vaccines. Imagine that your body is receiving detailed instructions for the most effective neutralization of foreign cells. Again, I think the choice is yours.
