Did the reaction to COVID weaken everyone's immune system

I'm not a physician or a biomedical expert, but I worry about this too. I used to get a mild cold once or twice a year. It has now been more than three years since I've had even a sniffle. I'm a little worried about how sick I'll get the next time I catch any "standard" upper-respiratory bug.

Possibly, although I haven't read anything about it.

I have read that in some people, covid reoccurred in 30 days from the same infection. I've also read that some critics of the vaccine fear that the vaccine will reduce overall immune system. Have you been vaccinated? Have you had covid in the past 30-60 days?

I see people all the time saying stuff like "I love masks, social distancing, and staying home... I haven't been sick in over 2 years!" But I'm pretty sure this is not normal.

I also used to get 1-2 colds a year, maybe a random sore throat here and there, the occasional stomach bug, but also have had almost no illness since the pandemic (oddly enough, except for COVID one time).

I had the flu several times in my life and was always recovered 100% by day 5. This time I'm at day 8-9 and still maybe at 90% despite being healthy, in great shape, hygienic, resting/drinking lots of fluids etc.

And this doesn't even take into account other illness caused by the COVID reaction, things like mental illness, alcoholism, etc.

It is exceedingly unlikely that 2 years would make such a large difference on most people. I haven't gotten COVID, but have gotten a few minor colds over the last couple years. I would consider getting a flu shot next year if your immune system is this shot to hell from the Flu.

Probably, my kids are back at daycare and just crushing everyone who comes into contact with them. Last week it was a stomach bug, I thought I was good but man did I get my butt kicked today at work.

I don't think you have any evidence to support this bold claim. Fortunately, most people have not been following the new rules very well and essentially should be fine because they have already been living like normal. Nobody really understands what two years of isolation does to the immune system, but it is known that even short periods of isolation alter immune function and one's ability to be prepared for changes in rates of pathogen exposure. I would guess it will take a long time for some to return to healthy immune function. I do think most people though were never really that isolated and will be just fine. The protected elderly groups will likely struggle the most.

I don't think anything I said was too bold. Most people have been traveling, eating out, and socializing intermittently throughout the Pandemic as conditions warrant. While their exposure is lower, it's not nothing. The main difference was mainly in a short period in 2020 when actual lockdowns were in place and for work or school where far more people worked from home. But that sort of lockdown has long been over.

The immuno-compromised protected elderly as you note are people who will always be vulnerable to the Flu, common colds etc.

That is fair. Some people have been in high isolation though, they may struggle a while. People who have over protected their kids during this time may watch them suffer for some time. We will see.

Fair enough. I think to the OP's question though...people who have treated COVID like this are not a high segment of the population. They're probably overrepresented voices on social media or on the news making think-pieces about going to a sporting event or restaurant for the first time or masking up at family gatherings...For the vast majority of people, I doubt a huge effect on their immune system.

The VACCINES weaken the immune system. The only way your immune system improves is with practice fighting off viruses. Vaccination does not provide the proper practice and exposure for the immune system. Time to wake up.
