The flu shot may not be as dangerous as you think.
Here are the facts.
article A new study suggests that people should be vaccinated if they’re going to get a flu shot, and that those who haven’t received a flu vaccine could be more at risk than others.
The study, published online this week in the journal JAMA Internal Medicine, looked at more than 8,000 people who got their flu shots between December 2016 and January 2017.
About 5 percent of those who got the flu shot during the study got the shot during their first year of follow-up, and about 4 percent got it during their second year.
Those who didn’t get a shot at all also were less likely to get sick and die from the flu, the researchers found.
But those who didn.
were more likely to have a weakened immune system and had lower levels of antibodies to influenza A virus than those who had gotten a flu jab.
And they were more than twice as likely to die from pneumonia, which was more common in those who weren’t vaccinated.
The researchers also found that people who did get a vaccine had higher levels of antibody to the influenza virus than people who didn’ t get it.
“This is a big, huge finding,” said study author Dr. John Loughlin, an assistant professor of medicine at Johns Hopkins University.
“It indicates that the flu vaccine is not a panacea,” Loughline told Reuters Health.
Loughloins study also found a possible link between vaccination and increased risk for pneumonia and influenza-related death.
About two-thirds of people who get vaccinated have the same type of antibodies as people who aren’t vaccinated, and a small number of people have a stronger immune response to influenza.
“People who have been vaccinated are more likely than others to have antibodies that are stronger than normal,” Lufflin said.
But he said it was hard to draw firm conclusions from this study because there was no follow-ups after the people stopped getting their flu vaccine.
“I don’t think it’s very likely that people vaccinated at any point will have antibodies like people who haven’ t gotten the vaccine,” Lighlin said, adding that the study didn’t address how the antibodies were formed or how long the antibodies stay strong after vaccination.
“In the next 10 to 15 years, we will be able to see whether antibodies form in people who have had flu vaccination and how long they last,” Laughlin said in a phone interview.
“That will help us understand how strong these antibodies are.”
Dr. Matthew Reuter, an infectious diseases expert at the University of Florida, said that Loughlyin study makes a “really important point” that some people may not have received the flu jab yet.
“The real question is, ‘Is it possible that people haven’t gotten the flu vaccination yet?'”
Reuter told ReutersHealth.
“There are a lot of questions that remain unanswered.”
Reuter added that it’s likely that there are some people who may be protected by the flu shots, and said it’s important to check out all the vaccination options before deciding whether to get one.
“We still have a lot more work to do,” he said.
A small number have lower levels than others and a stronger antibody response to the flu virus.
Reuter also said that the findings may have limited future research into how much flu vaccine people should get and who should get it first.
He said the new study didn’t address the question of whether it was more important to get vaccinated before getting a flu vaccination than before getting it.
But Loughlen and Loughner said that previous studies that looked at the flu and influenza vaccine before vaccination did find that it might be important to start the flu immunization plan sooner.
“Our research has not been able to determine whether it is more important now to get the flu vaccinated before receiving a flu immunizer or whether that is something that is more difficult to identify in this population,” Louglin said of the new analysis.
“But it does seem like the data is there that the timing of flu immunizations might be more important than before the flu.”
