To answer your question, I must tell you that the most important thing is that we know that vaccines protect against severe cases of the disease , but we do not yet know if those vaccinated can continue to infect or if they can infect themselves. Given this risk and no matter how low the viral load of a vaccinated person who has had contact with an infected person may be, there may be the possibility of infecting himself and others even though he is protected against the disease. Vaccinated patients must continue to maintain the known precautionary standards, that is:
1.-They must continue to use the mask properly, well adjusted and change it after the time of use (four hours for surgical or hygienic and eight hours for FFP2)
2.- They should continue to wash their hands frequently with hot water and soap and if they cannot, they should use hydroalcoholic gel.
3.- They should keep a certain distance with any other person who is not living together.
4.- And if they are going to stay with someone or participate in a meeting, they should try to be outdoors.
So, actually until we are sure if the vaccinated acquire immunity of the "sterilizing" type, that is, they are not conta gious or transmitters of the virus, you should continue to maintain the same attitudes towards others that you had before vaccination
In addition, it must be taken into account that depending on the type of vaccine that has been given, the vaccine efficacy varies between a 70-75% (Astra-Zeneca Oxford) and 90-98% (Moderna and N-Biotech Pfizer). You should also know that the acquisition of maximum immune protection is obtained ten to twenty days after receiving the second dose of the vaccine. So it is also important that until then you act exactly the same as if you were not vaccinated.
If we understand by normal life what we had before the pandemic, for the moment it will not be possible
As a final answer to your question, I will tell you that if we understand by normal life what we had before the pandemic , for the moment it will not be possible until we understand the coronavirus much better than the cause or until society acquires one. group immunity , for which there is still time. But in any case, the change that the vaccine implies for our lives is immense because it protects us from suffering a serious disease that can be fatal.
