The odds of both of you fully vaccinated getting covid, breakthrough cases they call them are rare.
Might have the new strain.
Published reports though even when a vax person gets covid the symptoms are mild in most cases.
You said you had symptoms two weeks ago if so, you should be almost done or done with your case, usually a 10 day period.
You will test positive for a covid test for up to 90 days or more after having a case of covid.
Hope you both get to feeling better soon.
