I do hope you and kids get well soon - but I just had to laugh at what you said. That sounds like it needs to be an advertisement on TV for some medicine.
My boy just had his tonsils and adenoids removed this past Wed. Even though he had the shot, the doc's beat it into our heads, "Do not let him outside for 7 days - no matter how good he feels - DO NOT! If he gets the flu he is in for a very hard time."
Adice heeded and my 9 yr old is about fit to be tied.

Sounds like a cold.
Immunization with Panama is pretty marginal for Fujian.
