			 While many people are getting their required second doses, the 
			process is taking a toll on some of the most vulnerable - older 
			adults who in many cases rely on family members or friends to 
			navigate complex sign-up systems and inconvenient locations. 
 Available vaccines need to be given as two separate doses weeks 
			apart, and confusion is further taxing an already challenged health 
			care system. Houston's health department on Friday told those 
			seeking a second dose to be patient, saying the volume of calls was 
			creating long wait times at its call center.
 
 As of Monday, 26 million people in the United States had received a 
			first vaccine shot, and almost 6 million had the second, according 
			to the U.S. Centers for Disease Control and Prevention (CDC). The 
			CDC has also said states lag in reporting data so it is unclear if 
			that might affect the dose counts.
 
			
			 
			
 “There's going to be some delay in getting second doses,” said Beth 
			Blauer, Executive Director at the Centers for Civic Impact at Johns 
			Hopkins University, who is tracking vaccination data for the 
			university’s Coronavirus Resource Center.
 
 She had expected the number of first doses to plateau as priority 
			populations began to get second doses, but that tapering off was 
			happening slower than expected.
 
 “We're still seeing the first dose climb which means that there's 
			going to essentially be an unrealistic expectation that you're going 
			to get your second dose, because we know that there's finite 
			supply.”
 
 SECOND SHOT PROCEDURES
 
 Practices vary. Seminole County in Florida schedules follow-ups 
			during the 15-minute observation period after people get their first 
			shots. New York's Onondaga County holds off on scheduling second 
			appointments until days before the shot.
 
 After an online system showed no appointments, Stacey Champion 
			secured a second appointment for her 78-year-old friend Dan Pochoda 
			at Cardinal Stadium in Phoenix, Arizona - at 1:51 a.m. on Feb. 9. It 
			took several calls to get even that, Champion said.
 
 "If they had been saving appointments for second doses, would they 
			really need to send people way out to the edges of the city in the 
			middle of the night?" Champion asked.

			 Many providers expect their 
								vaccine allocations to fall sharply this week.
 "When this started, it was only for hospitals. 
								Now a smaller pot needs to be divided between 
								many more - the pharmacies, the mega sites and 
								everyone else," said Felipe Osorno, executive 
								administrator of continuum of care operations 
								and value improvement at Keck Medicine of the 
								University of Southern California.
 
 People in recent days have been showing up at 
								USC hospitals seeking their second vaccine dose, 
								saying their original vaccine provider could not 
								confirm an appointment, Osorno said.
 
			On Twitter, concerns about getting the second shot are mixed with 
			triumphant tweets by many who got follow-ups on time, without drama.
 St. John's Well Child and Family Center, a network of public health 
			centers in South and Central Los Angeles, is running nine 
			vaccination clinics, and began administering second doses on Jan. 25 
			after sending email and telephone reminders to patients.
 
 "We screamed and yelled" to secure second doses on top of meeting 
			the need for first shot appointments, said Jim Mangia, the center's 
			president, who added most people are returning.
 
 West Virginia, a leader in getting shots into arms, hired critical 
			event management firm Everbridge to manage scheduling as it opens up 
			vaccinations to more groups.
 
 "Any time there's ambiguity, that's not a good feeling," said Andy 
			Malinoski, marketing director for West Virginia's Department of 
			Commerce.
 
			
			 
			Guidelines call for a second shot of Moderna Inc's vaccine four 
			weeks after the first dose, while the gap is three weeks for the 
			Pfizer Inc/BioNTech vaccine. The CDC has said an interval as long as 
			six weeks is acceptable for either vaccine.
