I am sorry to hear about your post COVID-19 trouble. It seems that a persistent cough -waxing and waning- is your major complaint. Such persistent cough is known to occur in a number of cases after COVID-19-and it can persist over weeks to many months. While there is no COVID-19 cough specific treatment- general over the counter or prescription cough treatments can be tried after other more serious causes for the cough have been ruled out. Your primary care doctor should be able to help you with that. In addition, one needs to think of other causes for the cough unrelated to COVID-19. For example certain medications used to treat high blood pressure can cause persistent cough, even after you had taken them without cough for a longer time. If you are currently taken a medication for high blood pressure that includes a medicine that ends with -artan (such as Losartan) or -pril (such as Lisinopril)- it should be looked into whether changing it to a different medication would stop the cough.

Flu vaccine effectiveness varies from year-to year, by age and underlying medical condition. Effectiveness is somewhat lower in children under age 2 and gets higher with aging towards adults. As said before a number of factors influence effectiveness range from about 30 to 70%. Since flu vaccines are proven safe a drop in overall population vaccination rate will result in an increase in infections and also increase in infections with hospitalizations and severe disease or death.

Can someone with CAEBV get a covid vaccine?

Your wife has a rare condition chronic active EBV infection, that can weaken her immune system and sometimes immunosupressants are used for treatment. I think your wife could be at higher risk for potentially worse COVID-19 disease if she would get infected- thus I would recommend that she gets the COVID-19 vaccine. Because this condition is rare- there are no specific data on safety and efficacy of the COVID-19 vaccines in CAEBV to lean on.
