Editor's note: Reminder that you are still required to make an appointment ahead of time for any of these vaccination events. Once the health department approves your request it will issue you a confirmation number that you should bring with you to your appointment time. Original story: If you’re one of the thousands of Houstonians lucky enough to have received a shot of Moderna’s COVID-19 vaccine from the Houston Health Department since it kicked-off public vaccinations to those who qualify on January 2, you’re probably feeling a combination of emotions. There’s the obvious excitement about being on the road to 94 percent immunity from this sorry disease that’s had the world in a headlock for the past ten months, but there’s also the uncertainty of when, where and if you’ll be able to get the second shot of the vaccine four weeks after dose number one, which is required to gain the maximum level of protection.
