“A flu vaccine only protects against influenza (flu), not the coronavirus. And while its effectiveness varies from year to year, people vaccinated against flu don’t get as sick, avoiding pneumonia, hospitalization and death.” Source: Associated Press
A new survey from the National Foundation for Infectious Diseases found just 45% of adult patients say they’ve been vaccinated. “It’s very concerning,” said Dr. Schaffner, “because that’s exactly the group that’s at highest risk of the complications of influenza, particularly pneumonia.” Source: CBS Miami
“Flu can cause immediate complications, including pneumonia, meningitis, and sepsis. Studies over the past decade show that even after the worst of the coughing, fever, and aches have passed, people are at increased risk for heart attacks and strokes in the two to four weeks after recovering from flu. The virus is even more nasty than you thought. Flu initiates a whole-body inflammatory reaction. The damage from flu continues even after one recovers from the acute flu illness … It’s why many people feel wiped out for two weeks or more after they’ve stopped coughing. This lingering inflammation can involve blood vessels, particularly the blood vessels to the heart and the brain.” Source: Everyday Health
“Vaccines are not just for children anymore. Over the years, a number of vaccines have been developed and now recommended for the adult population and particularly the middle age and older population, aged 50 and older.” Source: Infectious Diseases Consultant
“I think there are many people who were on the fence who were worried about things moving too rapidly and about possible side effects [of COVID-19 vaccines], but those concerns are being allayed as they see more of their friends and acquaintances celebrating getting vaccinated.” Source: The New York Times
