Flu vaccine offers benefits to patients with heart failure

New research found that heart failure patients who had a flu shot had a 30% lower risk of hospitalization for cardiovascular disease, 16% lower risk of hospitalization for respiratory infections, and a 4% lower risk of hospitalization in general. 

Are we prepared for epidemics?

Ask the Doctor

Q. Why is it that we suddenly have epidemics of things like Zika virus that we've never heard about, and that we have no treatments or vaccines for? It feels like we should be better prepared than we apparently are. This worries me more than terrorism.

Passing your physical exam

The annual check-up is important for older men. Here is how to make the most out of your visit.

Men have a long reputation for avoiding check-ups, and that resistance tends not to soften when they are older.

"Many older men put off exams because they fear finding out something is wrong," says Dr. Suzanne Salamon, a geriatrician with Harvard-affiliated Beth Israel Deaconess Medical Center. "Also, many of today's baby boomers don't think they will have medical problems associated with age, so it can difficult for the 'younger older men,' like those in their 60s and early 70s, to see their doctor."

In the journals: Flu-fighting drugs don't prevent spread to others

If you start taking an antiviral medication after catching the flu, will it keep your family members from catching the bug, too? Maybe not, according to a study in The Journal of Infectious Diseases.

The prescription antivirals oseltamivir (Tamiflu) and zanamivir (Relenza) can cut a case of the flu short by suppressing the virus's overpowering urge to copy itself inside you. Less viral "shedding" by the body could, hypothetically, make it less likely that people who live in the same house will also get sick.

4 vaccinations you may need

Adults need an annual flu shot and a Tdap booster every 10 years. People over 60 need a shingles shot, and those over 65 should have two pneumonia vaccines.

Ask the doctor: High-dose flu vaccine: Is it better?

Ask the doctor

Q. I heard there is a high-dose flu vaccine that could work better in older people. Is it safe even if a man has a medical problem like cancer or heart disease?

A. The high-dose flu vaccine is very similar to the standard flu vaccine but appears to provide slightly better protection against influenza. Both vaccines target three different strains of the flu virus, selected from the most common strains predicted to be circulating that year. The viruses are inactivated, or killed, so they cannot cause the flu, even in people with weakened immune systems. Finally, both vaccines can cause mild symptoms of arm pain, redness, muscle aches, or low-grade fever. Although most people have minimal to no symptoms, the high-dose vaccine may slightly increase the side effects.

Fall vaccination roundup

Vaccines are the best protection people have when it comes to certain illnesses. Older adults should get a flu shot every year.

Flu vaccination: Win some, lose some

If you got the flu shot last year and it didn't work, don't reject vaccination.

During last year's battle of The People vs. Influenza, the virus gained the upper hand. Early in the 2014–15 flu season, a new strain of the virus emerged against which the existing vaccine offered virtually no protection. Hospitalizations for flu in older adults spiked to the highest level in a decade.
