AUSTIN (KXAN) — One less shot and maybe fewer tears is what a new vaccine promises.

The FDA approved a new combination vaccine called Vaxelis designed for children ages six weeks to 4-years-old. The FDA says it keeps them from contracting diphtheria, tetanus, pertussis, poliomyelitis, hepatitis B and invasive disease due to haemophilus influenzae type B.

Right now infants get three shots to protect them against the six diseases, but with the new vaccine, there will be fewer shots.

“You’re getting vaccinated sooner and more effectively at a younger age and hopefully it will be more widely available to everyone, and you’re not going to miss vaccines,” explained Dr. Brian Temple with Beansprout Pediatrics in Bee Cave. “When you have multiple different shots there are errors so it’s nice to have it all in one.”

Krystal Small brought her baby boy in to be checked out after a cough. She will be back for Jack’s round of vaccines in a few days.

“I would want to know… you know is there any adverse reactions that could happen –  you know especially when they’re so – so little,” said Small. “You do get nervous, but I also want to protect…  I think the alternative is way worse.”

Dr. Temple said if parents have any concerns they should talk to their pediatrician.

“The amount will not affect a baby or a child’s immune system. Our bodies can handle it and they handle it very well,” Temple said.
