Holliston Pediatric Group will be offering only injectable flu vaccine for the 2018-2019 flu season. Every year, research is undertaken to determine the efficacy of flu vaccines. This year, the CDC has shown that the live attenuated vaccine, or nasal spray, was not effective in preventing the flu during the 2015-2-16 season. Therefore, the CDC has recommended that nasal sprays not be offered. In order to provide your children with the best opportunity to avoid the flu, we have decided to not offer Flumist nasal spray this season.
