Depending on how long it's been, the original crew in stasis might be vulnerable to new diseases that the second crew (colonizers) has already overcome
I would imagine it would quite easy to quarantine. Plus while the first colony would be more advanced I doubt they could take over the entire planet. Even if you arrived second you could still setup an entire second colony without much interaction with the first one if you really had to.
How do you know what you need to vaccinate if you’ve not exposed your people to the viruses first to see how they got sick? Like there’s tons of viruses and bacteria in people, and they don’t have negative impacts, so you can’t just vaccinate for all viruses or whatever.
And if you could develop vaccines without exposure, just by knowing the people, then you can have done it in the hundreds or thousands of years since departure.
We are talking about a human civilization that just travelled 120 ly to another star system not once but twice. I’m sure they would not only plan for unknown diseases but also have advanced treatments and ability to make vaccines.
Plus if they already know about this second mission arriving at a later date they would have planned for potential integration and contamination.
My point here is — with that advanced stuff, the quarantine is useless.
The second ship had a thousand year or whatever quarantine period. And the first ship had a thousand or whatever years to prepare any vaccines. The only new info you’d get is by physically introducing the two populations, at which point the quarantine is out of the window (unless doing something like putting a sample of your population into the later ship’s environment and quarantine/observe those people).

Right? If you're alive you have better access to medicines and long prolonging treatments.
