2/20/2024 0 Comments Flu shot side effect heartThe researchers monitored how many of these people died after they got flu shots for nine consecutive influenza seasons from 2007 to 2016. The researchers used nationwide health registries to identify 608,452 people 18–100 years old with high blood pressure. However, this had not been investigated.” Since people with high blood pressure have an increased risk of heart attack and stroke, we thought that preventing flu through vaccination might also protect against these diseases. “Our theory is that the flu stresses the body, and this can trigger heart attacks and strokes. However, the Danish research group already showed last year that people with heart failure who get flu shots have a reduced risk of death compared with those who are not vaccinated. Little is currently known about how influenza infection affects people with high blood pressure. Since this vaccination is both inexpensive and harmless, I think that everyone with high blood pressure should get a flu shot every year,” explains the first author, Daniel Modin, Research Fellow, Department of Cardiology, Herlev and Gentofte University Hospital. “Our study shows that flu vaccination among people who have high blood pressure is associated with an 18% lower risk of death during the flu season. ![]() Although the flu season is not yet here, some people should still pay special attention to new research showing that flu vaccination may be associated with a reduced risk of death among people with high blood pressure. But then your muscles start to ache, your temperature climbs alarmingly and you both sweat and freeze. Older people’s immune systems can wane over time, and therefore a larger dose of vaccine can help ensure an immune response.It usually starts out like a common cold with a cough, sore throat and runny nose. ![]() Lower doses are recommended for younger people and children primarily because their immune systems are more robust. The National Advisory Committee on Immunization recommends that people over 65 should get a high-dose flu vaccine. Health Canada guidelines state that people with acute symptoms of COVID-19 or any symptoms of acute respiratory infection, including a sore throat or runny nose, should postpone the flu shot until they have recovered. If you’re sick with COVID, how long should you wait to get a flu shot? Vaccination is a relatively easy way to avoid hospital visits for respiratory illnesses and complications. Anything we can do to protect hospitals and clinics from being overloaded should be pursued. Plus, we all know that COVID has tested the healthcare system and strained its resources. The National Advisory Committee on Immunization says there’s no real danger to having both vaccines very close, even during the same session. ![]() With the ongoing pandemic and the need for COVID vaccine boosters, what should people know about getting a flu shot?ĬOVID and the flu are two different illnesses the COVID vaccine won’t protect you from the flu, and vice versa. So immunizing to reduce the risk of flu can in turn reduce the risk of in-hospital complications. Studies have shown that the risk of stroke or heart attack increases shortly after a flu infection, but probably even more in someone who is predisposed to stroke.Īlso, the flu can lead to hospitalization. Having the flu can increase the risk of another stroke or heart attack. We know that those at highest risk of complications are people with chronic disease, including cardiovascular disease and stroke. Public health recommendations are that everyone over six months of age should get the flu vaccination. ![]() I recommend the flu shot to all my patients, especially older ones. What do you tell your patients about annual flu immunization? He spoke with Heart & Stroke about the importance of getting a flu shot this fall. Alexandre Poppe is a Heart & Stroke researcher and a stroke neurologist in the division of neurology at the University of Montreal Health Centre.
