In their paper posted on the...

by Nathan Bartlett, The Conversation Credit: Pixabay/CC0 Public Domain Last week, AstraZeneca’s chief executive officer said the company’s COVID vaccine may provide longer-lasting protection than mRNA vaccines like Pfizer’s, especially in older people. CEO Pascal Soriot said this might explain the United Kingdom’s more stable hospitalization rate compared to the escalating COVID situation in continental Europe. The UK...
Earlier this month, the US government recommended that children aged 5 to 11 get the Pfizer COVID-19 vaccine. Many parents had been waiting for this announcement since the beginning of the pandemic, but an authorization comes with its own challenges. Among those is helping kids in that age group understand the need for a vaccine. While there’s no...
by Children’s Hospital Boston Shown at far left, the vaccine consists of a portion of the spike protein’s receptor-binding domain (RBD), shown in dark blue, attached to a single domain antibody-fragment that recognizes class II major histocompatibility complex (MHC) proteins, shown as orange ovals. These conjugates home to antigen-presenting cells (APCs), which then process and display...
