A kiss and the COVID-19?

Earlier today my wife and I kissed very quickly on the lips for the first time in over 1 year. About 1 minute later I was concerned that we had passed on COVID-19 to each other even though we have spoken closely to each other in the past. I also think that was a terrible error on both our parts. Also, tomorrow I will be receiving my first COVID-19 injection and I am thinking that I should cancel my appointment. So, because of that, I have 3 questions to ask for both of us.

First question:

Will we get COVID-19 through a combination of the vaccine and the possible ingested saliva?

Second question:

Will the vaccine protect us from getting COVID-19?

Third question:

Will we both get COVID-19 sometime in the future after the virus has laid dormant for many years even though we have both taken the vaccine?

I do not fully understand your question. If you have been living together as man and wife for the past year, neither are sick, why should either of you worry about catching SARS CoV-2 from the other. Am I missing something? Get the vaccine tomorrow. It will not protect you for two weeks and if you receive either the Pfizer or the Moderna vaccine, you will not be fully protected until 2 weeks after the second dose. There is no dormancy with the SARS CoV-2 virus, so the only concern for the future is that the circulating virus might mutate and no longer be susceptible to the immune response your vaccination induces.

So:
-Do not worry about the kiss
-Get vaccinated to morrow
-The protection will be present in two weeks from now and fully protective two weeks after the second dose.
-Watch the news about any change in the future stages of the epidemic.

Best of luck.
First of all, if you have been living with your wife, and both of you have been following guidelines, there is no reason at all to not kiss her. You should have been kissing her all along! Secondly, you should NOT cancel a vaccine appointment because of this. You should go get vaccinated. Now I will answer your three questions in order:

1) No, you will not get Covid from kissing your wife. It is IMPOSSIBLE to get Covid from the vaccine, as it does not contain live viruses. There is no such thing as a “combination of the vaccine and kissing.” Maybe you are worried that the vaccine will somehow weaken your immune system or something? It will not.

2) The vaccine will likely protect you from getting Covid, yes. It is well over 90% protective. No vaccine is perfect, but these vaccines are about as good as vaccines get.

3) As far as we know, the virus does not “lay dormant” and then reactivate; there are some viruses that do that, but coronaviruses do not. So, no, you will not get Covid from a dormant virus.

I hope this helped.
