A new study says the flu shot may not be as effective as originally thought, but Dallas County still recommends people be vaccinated.
According to a study published by The Lancet, the flu vaccine is only effective in about 59 percent of the adult population. The study also said the vaccine may not be helpful enough in a global outbreak and that nasal sprays are better for children younger than age 7.
But the study isn't reason enough for Teresa Perez to stop getting the shot. She gets it every year and makes sure her little ones do as well.
"So many people get sick from it, people die from it, so I know they need it," she said as she waited at the Dallas County health clinic.
Dr. Steven Wilson, the medical director for Dallas County, said the vaccine is one of the most powerful tools in order to fight the flu. He said it can help fight complications in elderly.
"If more people got vaccinated, there would be less flu, no matter how effective the vaccine is," he said.
His advice is to get the shot as soon as possible so it is effective if you come in contact with the virus.
Wilson said the vaccine hasn't changed from last year, which is why it's so readily available this year. Manufacturers are always searching for ways to make it stronger, he said.
