I guessed also that this is not going to be regular vaccine. There will maybe 5-6 vaccine that we will have to take in order to stay healthy because it is like those right now are made to cause more problems. And in order to fix those we will have to take more vaccines. I would not vaccinate old people as their bodies are not strong enough to handle covid virus that is in the vaccine. Maybe vaccinate all other people so there is no anyone who would transmit them covid. That is maybe better option. For old people if they have survived until now, vaccine will finish them I'm afraid.
