Erroneous tweet causes confusion during soft launch of Third Ward vaccine clinic Published: Updated: Tags: HOUSTON – An erroneous tweet caused confusion and long lines Tuesday during the soft launch of a vaccine clinic in Houston’s Third Ward. According to Vanessa Astros, spokeswoman for St. Luke’s Health, the appointment-only clinic is scheduled to be fully operational by Feb. 15. However, a soft launch was conducted Monday and Tuesday to ensure everything goes smoothly for the full-scale clinic. Astros said everything went well Monday. She said that someone not affiliated with the clinic sent out a tweet that contained incorrect information and that caused people to start lining up Tuesday.
