Westlake-area resident Joan Skerry said she and her sister were excited to receive their first Moderna COVID-19 vaccines at a First Medical Response of Texas pop-up clinic on Jan. 2, held in the Dripping Springs Fire Department's parking lot. However, when their second shot deadline came and went last Saturday, Skerry feared the two would have to start the vaccine regimen anew.

Due to a misunderstanding about saving part of their vaccine allotment for the second booster shot the vaccine process requires, First Medical used up all of its shipment on first vaccines and didn't have any more doses left for the second round, co-owner Edwin Reyes told Austonia.

Almost a week overdue, Skerry's sister managed to get a second vaccine elsewhere before Ascension Seton contacted her with a slot that she gave to Skerry. Both qualify as 1B recipients—consisting of older individuals and those with chronic health conditions—for the vaccine, the second phase in the distribution effort designated by the Texas Department of State Health Services after first responders and healthcare workers in group 1A. Skerry is 72 years old and her sister is 66 years old.

"I was so relieved when (Seton) called me that I started crying—not my usual behavior," Skerry said of the news that she would receive a booster shot. "So my story has a happy ending."

First Medical worked with government officials and state representatives to finally secure the 1,800 vaccines needed to provide those first vaccine recipients with their second vaccines, scheduling a clinic Friday for distribution, Reyes said.

However, some residents aren't so lucky and are still on the hunt for a second dose, including those who received an initial dose from clinics that were able to extract 11 doses from a vial allocated for 10 doses. There's no assurance they can take out extra doses to coordinate with those individuals who received the "extra" doses the first time.

Jeffrey Warnken, pharmacist and co-owner of 38th Street Pharmacy, is one of those providers. He drafted a second dose waitlist that contains 25 to 30 individuals qualified under 1A or 1B as of Feb. 3.

Warnken said his pharmacy recently administered seven first doses to people with the understanding that they could not be assured of receiving a second dose from his facility. He thinks finding second doses will continue to be a problem until more vaccines become available.

"Instead of wasting it, it's better to give somebody a first dose with the possibility of not giving them their second dose because a half is better than zero," he said, adding that a single dose provides some immunity to the disease although the extent of that immunity is unknown. The protection from a single Moderna COVID-19 vaccine dose could range from 50% to 80% immunity after four weeks, Warnken said.

He's hopeful the pharmacy will get more vaccines in, especially with President Joe Biden's plan for the federal government to distribute vaccines directly to retail pharmacies like his facility.

Tarrytown Pharmacy's Pharmacist-in-Charge Rannon Ching also maintains a 1,300-name second dose waitlist for individuals looking for a Moderna booster. Because some individuals were able to find their first shot at independent locations, the opening of larger vaccine hubs have stranded those vaccinated by smaller sites that, as with Ching, haven't received additional doses in weeks.

He said he views those who aren't matched with a second dose fighting for that booster along with everyone else in the fight for a vaccine.

"The good thing about second doses is, once you give them, that's it and you don't have to coordinate for another dose," Ching said. "Second doses lend themselves well to those extra doses we pull out of the vial because those aren't accounted for and won't be accounted for to get second doses four weeks later."

His waitlist also includes individuals who want to make sure they have a "backup plan" in case something happens to their designated second vaccine and recommended first vaccine recipients return to their initial provider for the booster.

Austinite Leslie Lindzey, who received her first dose of the Moderna vaccine on Jan. 14 at Austin ISD's Delco Activity Center, isn't sure if she should pursue other options for her second dose. As of Feb. 4, she hadn't received word on scheduling her booster.

Although the vaccine hub isn't giving out second doses to individuals who didn't have their first vaccine through Austin Public Health, spokesperson Jen Samp said the department will be reaching out to first vaccine recipients for their second dose. As of Feb. 3, she said APH was waiting on news from DSHS regarding the second doses.

"We don't want to contact folks if we don't have the vaccine," Semp said about the second doses. "Once we secure the vaccine, we'll be contacting (them)."

On Jan. 21, the Center for Disease Control and Prevention updated its recommended interval for the two Moderna vaccines to include the scheduling of a second dose to be administered up to 42 days following the first dose if it isn't feasible to be timed at its recommendation of 28 days.

"The 28 days is not a deadline," Samp said. "It is merely an expectation that you should wait at least that amount of time before you get your second one."
