Though bear in mind the obvious - people get infected when they allow in outsiders like contractors, wintering staff arriving, tourists, etc. Over winter when you're in isolation there's nowhere for viruses to come from and the infection rate drops. Remote stations would probably also proactively get people to isolate so the whole crew doesn't come down with the lurgy at once.
It's not that your immune system is better, you just have a much smaller social network. Wintering staff are generally in good health anyway (the medical is extensive) which probably helps a bit. You also get a mandatory flu jab (this is not normal in my country unless you're old).
Once you get back into the general population, you pick up all the seasonal colds that you missed.
Edit: also check those references!
An outbreak of common cold at an Antarctic Base after seventeen weeks of complete isolation.
(from the abstract they never found the culprit - perhaps it got frozen onto a surface and then thawed later?)
I remember always feeling suddenly overwhelmed by people. You spend a few months with only a couple dozen people. Then you end up in NZ or Chile and fly back stateside. Suddenly there are thousands of people around.
Dang, I suddenly miss all my Antarctic peeps.
Came back to the US end of January (terrible timing considering the way things are going) and ended up getting sick with flu (not covid thankfully) and lots of digestive issues again. Now, heading into July... I haven't gotten sick again (likely from the isolation) and the digestive issues went away.
Our bodies are complex beings.
The more serious infections (cold, flu, covid) aren't a "gradual" immunity thing, they're individual strains that pack a hard punch in comparison to everything else. In part because we don't see anything super close to them on a regular basis.
Even worse, people aren't getting their flu shots (and other elective things) because they don't want to risk going to the doctors.
So when we get out of this covid jail... get ready for some interesting charts from the CDC.
Plenty of prior administrations appointment science-bound officials that held the line.
Why is that effect unfortunate?
Sounds a bit like you were searching for an excuse for a conclusion you arrived at already for other reasons.
The bulk of advances predate either development of widespread vaccination (largely 1930s - 1960s), or antibiotics (1940s), to say nothing of organ transplants (1950s-), cancer treatments (roughly same), imaging (1900s-), and advanced laproscopic surgeries (1970s-).
Basic sanitation (sewerage & solid waste), water purification, food safety, vector control (mosquitos), physical safety (falls, streets/transport, machinery), environment (soot, lead, asbestos, poisons), habits (smoke, drink, drugs), childbirth & childcare, sex ed, nutrition, and simple basic access to medical care count for far more.

I'm not disputing that vaccines are a powerful and beneficial tool, but that "the greatest life-saving achievement of modern medicine" is not in fact vaccination, but basic (and often quite pedestrian) public health measures.
This has been Laurie Garrett's thesis since at least the mid-1990s. And yes, she's also a strong vaccine advocate:

However, I will decide on yearly flu shots and others based on my own analysis, as clearly government sources have other things in mind that my best interest.
For example, I will wait 6 to 12 month after a covid vaccine is available to check postmarket studies.
A counter example is papillomavirus and shingles (vzw) vaccines, that I have decided to get, even if it's not recommended for me.
Having a legal system that can't arrest, charge, prosecute anyone because politics says not to means you don't have rule of law. If someone is recorded saying they committed sex offences then they should get a police interview regardless of their job.
Having a disease control department that can't give scientific advice because a political appointee won't like it; might as well close that department, it's no longer useful. Or, you could address the root issue.
I was coming from Vietnam and early on the govt. wasn't taking it seriously enough and had some major outbreaks. But they immediately got it under control. Contact tracing, testing, lockdowns, spraying, masks, hand washing, propaganda... and look... it worked. Zero deaths, zero new cases in 90+ days now. The whole country is open within its borders and people are safely interacting without any worries.
So, while I think the CDC is doing an ok job... at the end of the day, they totally missed the tidal wave coming at them.

At the current rate I am wondering if we get out, not when, lol
Pun intended?
Suddenly my allergies dropped. I made a test and I had no positive marker.
This went on for a couple of years.
This has changed since the lockdown. I am sneezing again all the time and wake up with sore throats, in the way it was typical. Even stronger than before.
The immune system needs work to do.
"Viruses do not live in Antarctica. When I was in the harsh and bitter cold, I was perfectly healthy. When I returned back home, I picked up every virus in Australia. I was totally unprepared for the way my immune system reacted."
I didn't know that our immune system could change so much so fast.
