Hi there, I signed up pretty early on for the Harris County vaccine waiting list. One of my friends told me they had received the call. I have a bad habit of screening my calls since I used to get a lot of sales calls, and saw I had missed calls from the same 832 number two days in a row that didn't leave a message, which Harris County does not do. So my question: Am I out of luck now? Now, the waiting list won't let me sign back up.
