In the past 2 years, researchers collected data from adolescents and children in order to improve the flu vaccines. The researchers found that the nasal flu spray is almost ineffective because it does not protect children as well as the normal vaccine.
The findings were based on data collected from 150 children that received the annual flu vaccine at a hospital in Pittsburgh.
The researchers took blood samples before and after the vaccines in order to see if the immune system responded to the flu shot.
The data has been collected by the University of Pittsburgh from various places in the region. They wanted to see if children responded well to the treatment and if they received the vaccine every year as they are supposed to.
The leader of the study is Richard K. Zimmerman, a professor and physician at this university who receives funding for the study from U.S Centers for Disease Control and Prevention. This institution is funding the study because they need to make some recommendations to other health institutions about the flu vaccine.
Data collected in the past two years showed that the nasal flu spray is not as effective against H1N1, the virus that has affected the most people in this period. This is why the nasal flu shot should be suspended because its effectiveness is limited.
Also, this means that all the children who were treated with nasal flu spray needed to be vaccinated as well because they could be in danger of catching the virus.
“Over the past two years, we found children who got the nasal vaccine were not as protected as those who got the shot “The first year it happened, we thought it was just a fluke. The second year, people were scratching their heads. ,” said an associate professor of pediatrics, Judith M. Martin.
Despite the fact that the nasal flu spray is not effective in some cases, it does not mean that is totally ineffective. It is just good for some children and it fights against some viruses, not all.
In the past, these nasal flu sprays had a better effect for children but apparently the viruses are getting more dangerous and harder to get rid of them.The best prevention for viruses remains the flu vaccine.
