Simply put, is it COVID-safe in Vegas
Things change so keep abreast of the news. The best resource in my opinion on that question is the Nevada Independent graphs on COVID cases, hospitalizations, deaths. They do a fantastic job compiling the info and making it easy to understand. Here's the link:

As a reminder, Vegas is in Clark County.
If your trip is scheduled for Spring then the weather should be nice enough to enjoy outdoor things safely without overheating. it can be a great time to visit Vegas because of that. However, double check the weather because we still do get some windy days and flash flooding in Spring.
Outdoors are pretty darn safe from COVID so you can enjoy some pool time, outdoor restaurant meals, hiking, sight seeing, etc.
If you do indoor stuff, some places may require vaccination to purchase tickets. That's being debated right now. So bring your vax card if you're vaxxed. Other places are going to be strict about the type of mask, so you should bring some high quality 'three layer' masks.
Like others have said, shows are still mostly canceled. I personally would not spend much time indoors, even masked and vaxxed. I just don't think it's worth it. But if you really like to gamble maybe you feel differently. You should know that by the time you visit, any adult living in Nevada who wants the vaccine will be eligible. And casino employees and food handlers became eligible a few weeks ago. So many of them might have had at least one dose by the time you visit. That said, I don't know how many aren't getting it. Nevada Independent has those stats too so you can look it up and get an idea of what percentage of locals got vaxxed. Of course though, most of the people you'll interact with will not be locals since most locals avoid the Strip unless they're working on it. Also, a fair number of people visiting Vegas do not take COVID seriously. So they might be lazy about masks etc. So that's why I would be cautious of indoor space.
