We've both had covid once only but it's the lingering after affects that are the problem.I and my husband had our first dose of Covid around 5th Dec last year. It was like a sleeping illness I couldn't stay awake.
Since then I've had an "upper respiratory infection"
Where I can't stop coughing and I still have it. OMG will it ever leave me alone.
I'm not enjoying it.
We had all of our injections and also the yearly flu vaccine. It's no laughing matter this Covid. I'm in my 70's so yes please use the antivirals if you get it.
