The City of San Antonio on Wednesday launched a text alert system to notify residents when COVID-19 vaccine appointments become available.
To sign up, text VACCINE or VACUNA to 55000. The alerts will trigger whenever one of the local public sites for inoculations receives more doses and opens registration. It is not a waitlist, and recipients of the alerts must still sign up for their vaccines as they normally would. The public sites the City has partnered with include WellMed senior centers and the University Health System.
