Bivalent COVID Boosters Offer No Extra Protection, Studies Suggest

Bivalent COVID Boosters Offer No Extra Protection, Studies SuggestWEDNESDAY, Jan. 11, 2023 (HealthDay News) -- The updated COVID-19 vaccine boosters intended to defend people against emerging Omicron variants don’t appear to provide any better protection than the original shot does, two new studies find.The new mRNA bivalent boosters produced by Moderna and Pfizer only attack the COVID-19 virus about as well as the companies’ first-wave vaccines, according to a blood testing study led by renowned virologist Dr. David Ho, a professor of microbiology and immunology at Columbia University, in New York City.The bivalent shots also failed to promote higher antibody levels or a better immune response than the original COVID-19 vaccines, according to another study led by Dr. Dan Barouch, director of the Center for Virology and Vaccine Research at Beth...

Happy, Loved Teens Become Heart-Healthier as AdultsWEDNESDAY, Jan. 11, 2023 (HealthDay News) -- When teenagers feel good about themselves and their lives, it may also do their hearts good in the long run, a new study suggests.Researchers found that teenagers who generally felt happy, optimistic and loved went on to show better cardiovascular health in their 20s and 30s, versus kids who lacked that level of mental well-being. Overall, they were more likely to maintain a healthy weight, as well as normal blood pressure, blood sugar and cholesterol levels. And having such positive feelings appeared particularly important for Black teenagers' future health.The idea that kids' well-being can affect their health well into adulthood is not new. Studies have shown that childhood obesity, for example, is tied to increased risks of various...

Global Acceptance of COVID-19 Vaccines Is on the RiseWEDNESDAY, Jan. 11, 2023 (HealthDay News) -- While COVID-19 vaccine acceptance rose around the world between 2021 and 2022, wide gaps remain, according to new research.Teams from the Barcelona Institute for Global Health in Spain (ISGlobal) and City University of New York (CUNY) also noted the need to address vaccine hesitancy with tailored communication strategies.“The pandemic is not over, and authorities must urgently address vaccine hesitancy and resistance as part of their COVID-19 prevention and mitigation strategy,” said lead researcher Jeffrey Lazarus, head of the health systems research group at ISGlobal.For the study, researchers surveyed people in 23 countries that were hard hit by the COVID pandemic. Collectively, those nations include more than 60% of the world’s...

Kids Living Near Airports Face Lead Poisoning DangersWEDNESDAY, Jan. 11, 2023 (HealthDay News) -- While U.S. policymakers have attempted to lower lead exposure among children since the 1970s, new research finds that kids living near airports are still being exposed to dangerous levels of the heavy metal.“Across an ensemble of tests, we find consistent evidence that the blood lead levels of children residing near the airport are pushed upward by the deposition of leaded aviation gasoline,” said study author Sammy Zahran, associate chair of economics at Colorado State University in Fort Collins. “This indicates we should support policy efforts to limit aviation lead emissions to safeguard the welfare of at-risk children,” Zahran said.When analyzing the blood lead levels of children under the age of 6 from 2011 to 2020, the...

Adults May Be Losing Immunity to Mumps. Are Boosters Needed?TUESDAY, Jan. 10, 2023 (HealthDay News) -- Despite routine use of a childhood vaccine, the United States still sees outbreaks of mumps. Now, a new study reinforces the belief that it's due to waning immunity post-vaccination.Mumps is a viral infection best known for causing puffy cheeks, a swollen jaw, fever and general misery. While it's usually relatively mild, mumps occasionally causes serious complications like brain inflammation and hearing loss.Because of that, children in the United States are routinely immunized against mumps, using the measles-mumps-rubella (MMR) vaccine.Yet mumps has seen a resurgence in the past two decades. Since 2006, there has been an uptick in annual cases -- often among college-age adults who were vaccinated as children, according to the U.S. Centers...
