...A new CDC report finds that the updated (2023-2024) COVID-19 vaccines cut the risk in half for visiting the emergency department, urgent care, or being hospitalized with COVID-19 for most people.
In 2020, all the precautions that helped people avoid Covid had an unexpected benefit: An entire branch of the flu’s family tree, a B strain that geneticists call the Yamagata clade, disappeared, and it hasn’t been detected since.
Researchers also found that vaccination against Covid, with either mRNA or viral vector shot, reduced the risk of developing a new autoimmune disease. They did not spell out in the study exactly how much vaccines reduced the risk of AIRDs.
the researchers found that long COVID was associated with how quickly inflammation and low iron levels regulated after acute infection. People who took a longer time to demonstrate regulation, and had more severe initial infections, were at an increased risk of long COVID.
The recommendation was approved by CDC Director Mandy Cohen, allowing the United States to join Canada and the United Kingdom in offering a spring booster this year to people at high risk of severe disease if they contract Covid.
