AHA News: Flu Shot Reduces Risk of Death for People With Heart Disease

AHA News: Flu Shot Reduces Risk of Death for People With Heart DiseaseWEDNESDAY, Nov. 18, 2020 (American Heart Association News) -- For people who have heart disease, getting a flu shot greatly reduces the risk of dying or developing serious heart-related complications, a new analysis shows.The meta-analysis of 16 randomized and observational studies covered the experiences of more than 237,000 people. It concluded those with heart disease who were vaccinated for the flu were 18% less likely to die from heart problems and 28% less likely to die from any cause. They also were 13% less likely to experience any type of major heart problem than those who didn't get a flu shot."Compare that to beta blockers and ACE inhibitors, which are used to control high blood pressure. They reduce mortality by 20-25%," said lead investigator Dr. Siva Yedlapati, an...

Chinese COVID Vaccine Appears Safe, EffectiveWEDNESDAY, Nov. 18, 2020 (HealthDay News) -- A Chinese COVID-19 vaccine seems to be safe and effective, early trial results suggest, but one expert says the findings should be regarded with caution.The CoronaVac vaccine is based on inactivated SARS-CoV-2 virus. It was tested in a phase 1/2 clinical trial that included more than 700 healthy volunteers, ages 18-59, who were recruited in China between April 16 and May 5.The vaccine appeared to be safe and well-tolerated at all tested doses, researchers reported. The most common reported side effect was pain at the injection site.Even at the lowest dose tested (3 micrograms), participants had strong antibody responses within two weeks of the second and final dose. Shots were given 14 days apart.Though levels of antibodies triggered by the...

Antibiotics Before Age 2 May Up Odds for Obesity, Allergies

Antibiotics Before Age 2 May Up Odds for Obesity, AllergiesWEDNESDAY, Nov. 18, 2020 (HealthDay News) -- Kids given antibiotics before their second birthday may have a heightened risk for chronic conditions like allergies and obesity, a new study suggests. The drugs' effect on the "microbiome" -- trillions of helpful microbes living in the human body -- might play a role in a baby's future health, Mayo Clinic researchers said.The study analyzed data from more than 14,500 children. About 70% of these children were given antibiotics before age 2. Those kids were more likely to have multiple illnesses or conditions later in childhood, the study found.Early use of antibiotics increased the risk of asthma, allergic rhinitis, weight issues and obesity, food allergies, attention-deficit hyperactivity disorder, celiac disease and atopic dermatitis, the...

Coronavirus Immunity Might Last at Least 6 Months

Coronavirus Immunity Might Last at Least 6 MonthsTUESDAY, Nov. 17, 2020 (HealthDay News) -- Immunity to the new coronavirus may last six months or longer after people recover from infection, a new study suggests.Researchers collected blood samples from 149 patients who had COVID-19 early in the pandemic and analyzed them for immune cells that make antibodies that block the SARS-CoV-2 virus from entering cells.One month after infection, all of the patients had coronavirus-fighting antibodies. Six months after infection, those antibodies were more potent and better at fighting mutated versions of the virus.The work, which was posted online Nov. 5 as a preprint to, hasn't undergone peer review. Research is typically considered preliminary until it has been peer-reviewed.The findings suggest that the immune systems of people...

Are We Getting Closer to a Herpes Vaccine?

Are We Getting Closer to a Herpes Vaccine?MONDAY, Nov. 16, 2020 (HealthDay News) -- Scientists are reporting early success with an experimental herpes vaccine that uses a genetically modified version of the virus.The gene edit prevents the virus from performing its normal evasive maneuver: hiding out in nervous system cells in order to elude the immune system.So far, the vaccine has only been tested in lab animals. But scientists hope the genetic tweak will eventually allow the vaccine to succeed where past ones have failed.The target is herpes simplex virus (HSV), which in humans includes HSV-1 and HSV-2. Both can cause genital herpes (though HSV-1 is best known for triggering cold sores). Globally, a half-billion people aged 15 to 49 have a genital herpes infection, according to the World Health Organization.Those figures...
