Latest data shows Moderna, Pfizer vaccines reduce infection risk by 91%
Data released Monday by the U.S. Centers for Disease Control and Prevention shows the two-dose Moderna and Pfizer/BioNTech vaccines reduce the risk of a coronavirus infection by 91%.
The risk of infection was reduced by 81% among those who were partially vaccinated.
The data also shows that anyone who is fully vaccinated is much less likely to develop serious symptoms if they do contract COVID-19.
The latest data is from an ongoing study of vaccine effectiveness. It involves health care workers, first responders, frontline workers and other essential workers, who are much more likely to be exposed to the virus.
Those who were fully vaccinated but contracted COVID-19 had better outcomes, the data showed. They tended to have milder and shorter illness and had a 60% lower risk of developing symptoms.
COVID-19 causes more complications than the flu in children and adolescents
A study published in the journal Pediatrics found that COVID-19 is more likely to cause complications in children and adolescents than the flu.
The study looked at outcomes for more than 242,000 children and adolescents from U.S., France, Germany, Spain and South Korea. All were hospitalized with COVID-19.
The most common complications were hypoxemia and pneumonia. Pediatric patients hospitalized with COVID-19 were also more likely to develop labored breathing, loss of smell or gastrointestinal symptoms compared to those hospitalized with the flu, according to the study.
The study again confirmed that children and adolescents are very unlikely to die of COVID-19 complications.
Study finds bots are the primary source of coronavirus misinformation on Facebook
Facebook groups targeted by bots were more than twice as likely to spread coronavirus misinformation than those who were less influenced by bots, a new study found.
The study, published in JAMA Internal Medicine, tracked how Facebook groups shared and commented on an article assessing the effectiveness of face masks. It found the groups infiltrated by bots were much more likely to share misinformation claiming masks “harmed” the wearer. More than half of the posts in those groups also shared conspiracy theories questioning the legitimacy of a clinical trial.
By contrast, less than one in 10 posts to groups that weren’t as affected by bots shared misinformation, and just over 20% shared conspiracy theories about the clinical trial. Nearly three-fourths of posts shared the information without any false claims.
People with active cancer more likely to die of COVID-19, study finds
Someone who is actively receiving treatment for cancer is more likely to die of coronavirus complications than someone with a history of cancer or who’s never had it, a study found.
Those who were at least three months removed from their last cancer treatment did not have a higher risk of death, according to the study in the journal Cancer.
Among cancer patients, those being treated for blood cancers or lymphoma had the highest risk of death from COVID-19.
Researchers from the NYU Langone Medical Center in New York City analyzed data from 4,200 patients hospitalized with COVID-19, including 233 being actively treated for cancer.
The researchers found 34% of the active cancer patients died of coronavirus complications. That was higher than the 28% death rate for those with a history of cancer, and a 20% death rate with no history of cancer.
