Studies Show Power of Pfizer Vaccine Starts to Wane After Two Months

Studies Show Power of Pfizer Vaccine Starts to Wane After Two MonthsTHURSDAY, Oct. 7 (HealthDay News) -- Two new studies confirm that the immunity offered by two doses of Pfizer's coronavirus vaccine drops off after about two months, although protection against severe disease, hospitalization and death holds strong. The reports, from Israel and Qatar, add to evidence that suggests even fully vaccinated people need to continue to guard against COVID-19 infection.In one study, Israeli researchers found that antibody levels among 4,800 health care workers fell rapidly within months after two doses of the Pfizer vaccine, "especially among men, among persons 65 years of age or older, and among persons with immunosuppression."That study also found that that immunity lasts longer in people who are vaccinated after natural COVID-19 infection.In the other study...

Japanese Scientists Discover New Disease Carried by TicksTHURSDAY, Oct. 7, 2021 (HealthDay News) -- Scientists in Japan have discovered yet another tick-borne virus that can make people sick.The Yezo virus is transmitted by tick bites, and triggers fever and a reduction in blood platelets and white blood cells."At least seven people have been infected with this new virus in Japan since 2014, but, so far, no deaths have been confirmed," said Keita Matsuno, a virologist at Hokkaido University International Institute for Zoonosis Control."It's very likely that the disease is found beyond Hokkaido, so we need to urgently investigate its spread," Matsuno said in a university news release.In 2019, a 41-year-old man was hospitalized with fever and leg pain after possibly being bitten by a tick while walking in a local forest in Hokkaido. He was...

Western Wildfires Are Making Easterners Sick: U.S. StudyTHURSDAY, Oct. 7, 2021 (HealthDay News) -- You might think that wildfires in the western United States would only affect folks in places like Colorado, California or Oregon.But a new study estimates that three-quarters of smoke-related deaths and visits to the emergency room for asthma in the United States happen east of the Rocky Mountains."We don't often talk about smoke in the East," said Katelyn O'Dell, who led the study while at Colorado State University in Fort Collins. "I wonder if there's a lack of awareness because you think, 'Oh, that's a western problem.'"While smoke does, indeed, contribute to a larger percentage of health problems in the West, it affects greater numbers of people in the East, the study authors said.In the western United States, where the population density...

1 in 7 Cancer Patients Worldwide Missed a Surgery Due to PandemicTHURSDAY, Oct. 7, 2021 (HealthDay News) -- In yet another illustration of how the pandemic wreaked havoc on medical care, a new report shows that 15% of adult cancer patients worldwide didn't get potentially lifesaving surgery due to COVID-19 lockdowns."Our research reveals the collateral impact of lockdowns on patients awaiting cancer surgery during the pandemic. Whilst lockdowns are critical to saving lives and reducing the spread of the virus, ensuring capacity for safe elective cancer surgery should be part of every country's plan to ensure continued health across the whole population," said co-lead study author James Glasbey, from the University of Birmingham in the United Kingdom."In order to prevent further harm during future lockdowns, we must make the systems around elective...

Are Breast Self-Exams Necessary? The Answer May Surprise YouTHURSDAY, Oct. 7, 2021 (HealthDay News) -- A shift in thinking means it's OK to skip your monthly breast self-exam — but don't miss your regular professional checkup and diagnostic imaging, health experts say.A periodic visual check in a mirror can be helpful, breast health experts from the Cedars-Sinai health system in California suggest."Beginning at age 40, women with an average risk for breast cancer should rely on annual mammograms, plus clinical breast exams by a primary health care provider, gynecologist or breast specialist," said Dr. Mary El-Masry, a breast medical oncologist at Cedars-Sinai Tower Hematology Oncology in Beverly Hills, Calif. "Still, it's good for women, beginning at age 18, to become familiar with how their breasts look and get attuned to any changes."While...

Intense Workouts Right Before Bed Could Cost You SleepTHURSDAY, Oct. 7, 2021 (HealthDay News) -- If you intend to run, bike or put in a Zumba video after work, plan on doing it sooner rather than later. A workout that ends a couple of hours before bedtime should help you fall asleep, while one that's closer to bedtime could have you counting a lot of sheep."Overall, our analysis showed that when exercise ended two hours before bedtime, there were sleep benefits, including the promotion of sleep onset and increased sleep duration," said study co-author Emmanuel Frimpong, a postdoctoral fellow at the Sleep, Cognition and Neuroimaging Lab at Concordia University in Montreal. "On the other hand, when exercise ended less than two hours before bedtime, sleep was negatively impacted. It took longer for participants to fall asleep and sleep...
