If you or someone you know is experiencing flu symptoms, you should take a flu shot, according to a study published Wednesday in the journal Science Translational Medicine.
The study is the first to look at the impact of flu vaccines on the immune system, which has been linked to a host of serious complications, including hospitalization and death.
The new study found that a flu vaccination boosted the immune response of patients in a lab setting to a level similar to that seen during an actual flu attack.
The authors of the study said the results suggest that flu vaccines can boost the immune responses of patients, especially in the short term, as the immune cells of patients get accustomed to flu-like symptoms.
The results suggest a vaccine could prevent flu-related complications in the long term, the authors said.
The scientists also found that the flu vaccine did not affect the immune systems of the healthy people in the study.
This is the second study published in the past week to show that flu vaccine can boost immune responses in healthy volunteers.
In a study conducted earlier this month, the researchers found that flu vaccinations boosted the numbers of healthy people immune cells in lab settings to levels similar to those seen during a real flu attack, and that those results were replicated in a randomized controlled trial.
In this new study, the investigators focused on healthy volunteers who were vaccinated with the influenza vaccine, and tested the effect of flu vaccine on their immune system.
The researchers found flu vaccine increased the number of healthy volunteers immune cells to levels comparable to those observed during an influenza attack.
This was found in a small sample of healthy participants in a controlled trial, the scientists said.
This study shows that a single dose of the influenza-containing vaccine can significantly boost the immunoglobulin-A (IgA) response in healthy healthy volunteers to levels significantly greater than those observed in an actual influenza attack, the study found.
The team said the findings support the idea that a small dose of flu vaccination could prevent a person from developing a serious flu-associated illness.
This may be due to the fact that the immune cell response to the influenza virus is very different from that of an actual, serious flu attack that can trigger serious complications and require hospitalization, said study author Robert P. Buss, MD, MPH, a researcher at the Mayo Clinic in Rochester, Minnesota.
The immune cells are not fully formed until the first week after a vaccine is administered.
The investigators found that people who received a single shot of flu shot at a laboratory setting experienced a modest increase in their immune cell numbers that was not significantly different from the flu attack response seen in a real attack.
The team noted that this could be due, in part, to the flu virus being smaller than the cells seen during the real flu-attack attack.
They said they found that these results may be linked to the ability of the flu to stimulate the immune defenses of the immune tissues in the human body.
The cells that are most sensitive to the natural influenza virus are also the ones that have been identified to be activated by the flu.
The ability of a flu-containing flu vaccine to stimulate these immune cells has been known for a long time.
Flu vaccines contain the active ingredient for the virus, a component known as conjugate conjugates (CCs), which can activate the immune proteins known as T cells.
These proteins help the immune tissue protect itself against other viruses, and they also stimulate a person’s immune system to respond to the threat of a new infection.
The new study suggests that a vaccinated individual may experience a mild flu-induced reaction that may not be severe enough to be life-threatening, the team said.
They noted that people with mild flu reactions have not been known to be at high risk for developing serious reactions.
Buss said the next step for the researchers is to determine how flu vaccine affects the immune status of people who receive the flu shot.
It is unclear how many people would benefit from flu vaccination and how long the flu vaccination would last.
This study was funded by the National Institutes of Health.
