According to the new research data published in the Vaccine, without using the nasal spray as an immunization option, the vaccination rates in children have dropped down in 2016-2017. Several research studies have taken place which helped in finding that the nasal spray to be less effective than the regular injectable vaccine.
CDC (Centers for Disease Control and Prevention) has reversed its initial stance on vaccine and recommended it to be used against the use of nasal spray for 2016-2017 influenza seasons. A study led by Penn State College of Medicine researchers was held to test the efficacy of the vaccine. Vaccine efficacy rates were assessed among the pediatric patients aged between 2 to 17 years old in 2014-15, 2015-16 and 2016-17 flu seasons.
Among the participants who took part in the research study, influenza vaccination rates in early 2016-17 were initially higher by 2% than they were in 2015-16. The vaccination rates dropped, however, there is an overall reduction of 1.6% when compared to the previous influenza season. However, the researchers also noted that there is a decline in revaccination rates in children who had received the nasal spray in the previous year.
There is 1.6% reduction in vaccination rates and the researchers noted that it could result in 1.2 million unvaccinated children. The overall findings indicate that around 35% to 50% of individuals changed their mind of receiving the influenza vaccine from 1 year to the upcoming year. This study also seems to suggest that the immunization preference is based on convenience.
Study co-author Ben Fogel, assistant professor of pediatrics at Penn State College of Medicine and medical director of Penn State Primary Care, said in a press release. “Rather if it’s convenient, they’ll get the vaccine, and if it’s not convenient, they won’t go out of their way to get it.”
The research also intends to conduct a follow-up intervention study to help improve vaccination rates among individuals who may not feel strongly about the efficacy of influenza vaccine.
