Vaccination isn't a guarantee of immunity against Covid, but ....
Unvaccinated people are about 29 times more likely to be admitted to hospital with Covid-19 than those who are fully vaccinated, according to a study released by the US Centres of Disease Control and Prevention (CDC) last week.

I'm not sure why people have the attitude that they're immune just because they've been twice vaccinated. This is no means put them in the clear but might keep them out of ICU and be treated at home.
They're also working on a booster vaccine currently to be rolled out towards end of September onwards to seal-it. If we go back in time we all had boosters a while after been immunized/vaccinated when we were kids. (including my kids) Why would it be different now?
...and we see the unvaccinated here too mostly being hospitalised.
I have a cold and have lost my voice. In one of the wakeful times last night I was googling the difference between Covid and a cold. I have no fever, I'm sure it is a cold, but in the dark hours of the night your mind goes weird places. I have been vaccinated, and if given a chance to get a third I surely will.
I understand your concern and I'm so glad you don't have a fever.
@HippieChick58 I'm so sorry you're sick, and I think it's perfectly natural to have this playing on your mind the whole time - especially in the middle of the night. I had a bad cold a month ago and, after being kept awake with a dry cough five nights in a row (especially after recent cervical spine surgery - ugh!), was worried enough that I saw my doctor. She was out of Covid tests, but treated me with amoxicillin and steroids which worked.
You no doubt read that the Delta variant doesn't necessarily need a fever or loss of taste, but presents as a bad cold, so if your symptoms persist, please consider seeing your doctor. I think your vaccine will protect you, but better safe. I, too, will be getting a third vax if I can.
