TEXAS — Texas health officials are concerned about a rise in vaccine hesitancy, following the Centers for Disease Control and the Food and Drug Administration's decision to press pause on the Johnson & Johnson vaccine. 

The CDC held an emergency meeting Wednesday. They took no action on the vaccine, saying they need more data and will meet again in about a week. 

Health officials are investigating reports of blood clots in six women. One person died. 

So far, nearly 7 million people in the U.S. have gotten the single-shot vaccine. In Texas, about 500,000 doses have been administered. The CDC and FDA said they made the decision to press pause out of an abundance of caution. Texas providers are being asked to continue storing the vaccine in proper conditions while awaiting further guidance.

Dr. David Lakey, the vice chancellor for health affairs and chief medical officer at the University of Texas System, said taking the Johnson and Johnson vaccine out of commission puts a strain on the state's vaccination efforts. 

"A significant portion of the total vaccine that was coming to the state of Texas was going to be the J&J vaccine," he said. 

It was being sent to retail pharmacies, rural areas, the Save our Seniors program and the state wanted to use it on college students in order to get immunized before heading home. 

Dr. Lakey said it's still critical Texans know the Pfizer and Moderna vaccines are safe and effective. He also noted the potential adverse reactions appear to be extremely rare in the J&J vaccine, occurring in less than one in every million recipients.

"Your chances of being struck by lighting are one in 500,000, so again, it's a very rare event. We need to get more information to make sure that data holds true," he said.
