Second Doses

The Houston Health Department is reaching out by text message and email with information to schedule second doses of COVID-19 vaccine. The messages contain a survey link for people to self-register for a second dose appointment.

The messages are sent 24-48 hours before Moderna's 28-day recommended due date. Please only call if you have not received a message within that timeframe.

People with internet or technology challenges and those who don’t receive a message should contact the COVID-19 call center at 832-393-4220.

If contact information has changed since a person received their first dose from the health department, please alert the call center.

Who Currently Qualifies

Everyone who wants to get vaccinated will eventually be able to do so but initial doses are allocated for critical populations as identified by the Texas Department of State Health Services:

  • Phase 1A focuses on front-line health care workers and residents of long-term care facilities.
  • Phase 1B focuses on people 65 and older and those with medical conditional that put them at greater risk of severe illness from COVID-19.

Vaccine is anticipated to be more widely available to the general public by approximately May. In the meantime, please be gracious and allow those at higher risk to have access sooner.

General Information

As vaccines are authorized, there will be a limited supply at first as manufacturing and distribution ramps up.

As vaccine availability increases in 2021, people will be able to get vaccinated at doctor’s offices, pharmacies, hospitals and other “usual” sites.

Each vaccine recipient will receive a card with information about the vaccine they received, and doses administered will be recorded in ImmTrac2, the state immunization registry, so that providers and recipients can ensure they receive the correct second dose.

Even when vaccines are available, people will need to take precautions like masking up, practicing social distancing and washing hands to help stop the spread of COVID-19 as people get vaccinated and we learn more about the immunity produced by the vaccines.

Safety and Efficacy

Vaccines are cleared for Emergency Use Authorization after rigorous review by FDA based on scientific evidence about safety and effectiveness gathered through large clinical trials.

The COVID-19 vaccines in the U.S. do not use the live virus that causes COVID-19.

Having symptoms like fever after getting a vaccine is normal and a sign a person’s immune system is learning to fight the virus.

COVID-19 Vaccine Conversations

Communities of color across Houston have been hit disproportionately hard by COVID-19, particularly the African American and Hispanic communities. It is essential to address the concerns many people of color have about vaccines due to historic and cultural factors.  Learn more at houstontx.gov/getthefacts.
