In February, we reported on a study from the University of Minnesota which showed a small number of flu shots can be effective for some people with a specific type of flu virus.
A few weeks later, the Mayo Clinic announced that it was dropping the study, and it seems like many others are too.
The Mayo Clinic study was supposed to determine the effectiveness of flu vaccines, but a few years ago, the company dropped it.
The reason was that researchers found that the flu shot was far more effective than the flu vaccine given to healthy people, and there was no way to tell whether a given flu shot would work in people with flu.
In other words, the vaccine could work, but it was not 100% effective in a real world situation.
But the Mayo study didn’t address the issue of how effective flu shots are in people who have already been vaccinated, which is what many experts are concerned about.
Now, a new study from researchers at the University at Buffalo has found that in the real world, flu shots do work.
In fact, they work quite well.
“The study found that influenza vaccination is associated with a significant decrease in the number of circulating influenza virus RNA (IL-1 and IL-2), and influenza vaccine-induced IL-1 responses were not significantly different from those without vaccination,” the study stated.
It also found that flu shots reduced the risk of contracting influenza infection in healthy people by about 40 percent.
In the new study, researchers looked at the flu vaccination efficacy of different flu vaccines and found that different flu shots were equally effective in decreasing influenza virus infection, as well as lowering the risk.
The researchers also looked at how effective each vaccine was in decreasing the number and severity of infections.
Overall, flu vaccine effectiveness was similar to that of placebo, but different from that of the flu shots given to those who had already been given flu shots.
And in the study of the two flu vaccines given to people who had been vaccinated with the standard flu shot, the flu vaccines were more effective at reducing the number, severity and frequency of flu-related illness than the placebo flu shots in the same people.
“Overall, the findings of this study support the safety and efficacy of influenza vaccination as a preventive measure,” the researchers concluded.
It’s a great result, and if you’re on the fence about whether you should get vaccinated, this study makes it easy to get on board.
“For those who have not yet received flu shots, and who do not currently have influenza symptoms, influenza vaccination may be an important option,” the authors wrote.
“In a study of more than 12,000 people, influenza vaccine efficacy was found to be similar to placebo in reducing the risk for influenza-related morbidity and mortality.”
In addition to reducing the likelihood of influenza infection, flu vaccines are also proven to prevent some infections.
In a 2014 study, the CDC reported that flu vaccines prevent an estimated 7.6 million infections, including pneumonia, influenza-associated respiratory illness, pneumonia-related bloodstream infections, pneumonia and bronchitis.
And the researchers who did the study also found there were some benefits to getting the flu inoculated, too.
“A recent large multicenter study showed that the vaccination of children was associated with decreased rates of pneumonia and influenza-induced hospitalization in both vaccinated and unvaccinated groups,” the investigators wrote.
“The effect of vaccination on hospitalizations for pneumonia and hospitalization for influenza was similar in both groups.”
“Overall influenza vaccine effectiveness has been found to decrease the risk and severity and duration of influenza-like illness, but there is a small risk of vaccine-associated morbidity in vaccinated and unprotected individuals,” the Mayo researchers concluded, so the benefits of flu vaccine are still small.
But don’t be discouraged if you still want to get vaccinated.
The CDC’s flu vaccine program, called the CDC Collaborative Program for Immunization, provides vaccine coverage to people up to age 26 who have been living with the flu.
For those who haven’t been vaccinated yet, you can get a flu shot by going to your local HealthCare.gov site.
