Yesterday I did not immediately understand what they were asking me about. It turned out that there are two different questions.
Some commentators were worried about the adenoviral vector, which is part of the Sputnik vaccine.
That old adenovirus that we all know (well, from which red eyes and all that), it is very much changed inside the Sputnik. This adenoviral vector cannot multiply in our body.
The vaccine is injected into the muscle and it quickly enters the bloodstream. There the virus will float and enter different cells of our body.
This adenoviral vector does not jump out of the blood and does not attack the people around it. This is clear.
Now the second half of the questions. They are about the possibility, after a successful vaccination, to pick up a virus and infect others.
And here everything is complicated. There are vaccines that create the so-called sterilizing immunity. In relation to the current epidemic, this could be a live vaccine that is injected into the nose, lives there, multiplies and creates local immunity in the nose. Then a dangerous virus will not attack such a hardened nose. This is called sterilizing immunity. The enemy will die in the nose.
Such vaccines usually create good local immunity in the nose, but poorly raise antibodies against the dangerous virus in the blood. If the enemy breaks into the blood, they will kill us.
To prevent the enemy from killing us, we need to have antibodies of class G. They float in the blood and protect our lungs from fatal pneumonia.
In the nose on the mucous membrane, sterilizing immunity is provided by class A antibodies. These are the so-called secretory antibodies. We have already discussed them in the story about bacterial overgrowth in the intestine.
The Sputnik vaccine helps our body build up class G antibodies in the blood. They won't let us die. But the Sputnik vaccine rather does not work on the nose and on antibodies of class A. That is, we can become infected with a dangerous virus, it will multiply in our nose and stand out.
Over the past months, I have come across three explanations on this matter.
Firstly, immunologists said back in the spring that all promising vaccines poorly stimulate immunity in the nose. Not that they don't work at all, but bad.
Secondly, some experts directly say that a vaccinated person is more likely to not get sick, but can infect others, because he will have a breeding ground for the virus in his nose.
Thirdly, some people think that in the worst case, just a swab from the nose will be positive, and you may be rejected somewhere at the border.
Personally, I think you need to get vaccinated in order not to die of pneumonia.
Personally, I think you need to keep wearing masks because you can catch the virus and then pass it on to others.
Personally, it seems to me that this is not as scary as if you spit sputum at others with viral pneumonia, but you still need to wash your hands and it is better not to sneeze at old people.
Personally, 72 hours after vaccination, I do not feel any reaction to the vaccine.
