A study on the flu vaccine, conducted by the University of Minnesota found it was not as effective during some flu seasons especially for the elderly.
The study says the shot protected adults about 59% of the time and didn't offer much protection to children or seniors.
The flu mist offered protection 83% of the time for adults but again little protection to kids or seniors but even the researchers still urge people to get the vaccine says Michael Osterholm of University of Minnesota's Center for Infectious Disease Research and Policy, "We believe current influenza vaccines will continue to have a role in reducing influenza morbidity until more effective interventions are available but we can no longer accept the status quo regarding vaccine research and development."
And a reminder for pregnant women, you're more at risk during flu season.
Doctors at the Cleveland Clinic say the flu is more likely to cause severe illness in pregnant women. Not only are the women more vulnerable but their babies may be affected too.
That's why doctors recommend the flu vaccine for pregnant women and it's safe to get at any time during any trimester, Dr. Susan Rehm of the Cleveland Clinic says, "We know that pregnant women who get vaccinated for the flu have healthier babies. They also pass on their antibodies to the newborn in the first 6 months of life. We can't give the vaccine and don't give the vaccine to babies, but having her antibodies helps."
Doctors say pregnant women should only get the flu shot not the nasal mist.
