Late on vaccinations?

We’ve been on the road working with my SO and haven’t been home for 4 months. And my 2 year old is late on her 24 month vaccines. I’ve been beating myself up about it . And I’ve tried to make an appointment for the week we go home and the only open appointment is July 18. But we will be back in Texas by then. What should I do? 😩 I feel like a crap mom.
