    Dr. Thank you for this well-written, informative & easy to understand article. Without oversimplifying you effectively conveyed the information in such a way that I could comprehend, without having a doctorate myself. I have already received 2 doses of the Pfizer vaccine earlier this year, and 2 days ago I started having severe sinus pressure, runny nose, VERY sore throat, bad headaches. I am so worried I may have been infected with the delta varient.
    Thank you for this timely information!

      .. so - there is no other cause of runny nose than covid...? Especially during summer time, when air conditioner are working and it is very easy to be sick..?
