There is likely never going to be a COVID free summer. Of course it can happen in the US. There has been evidence (that nobody wants to believe) that the protection from the vaccines wanes pretty quickly. There was a huge study out of Switzerland (I think, possibly Sweden) pre-Omicron that concluded that protection, especially in males, was pretty much gone after 90 days. The hope was/is that the booster dose makes it last longer, at least against severe illness.
I fully expect there to be future waves that show up every few months. Honestly, I'd be pleasantly surprised if there wasn't a new wave by memorial day, let alone labor day.
The only way the endless cycle will be stopped is if a vaccine is developed that is highly effective against a broad range of variants and is able to prevent infection at a very high level of efficacy.
It just is what it is. Maybe natural immunity lasts longer (which could be a benefit to certain areas of the USA) because, at least so far, the curve in South Africa (which was not highly vaccinated like the UK) does not show any signs of a similar uptick.
