An intranasal COVID-19 vaccine elicits long-lasting immunity against SARS-CoV-2 variants in vivo
A team of scientists from the Washington University School of Medicine and the University of Texas Medical Branch, USA, has recently evaluated the durability and robustness of an adenovirus-vectored, spike-based intranasal coronavirus disease 2019 (COVID-19) vaccine in mice.
Their analyses reveal that a single dose of the vaccine is capable of inducing both neutralizing and binding antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its variants for a prolonged time period.
Background
As of May 11, 2021, there have been 159 million confirmed cases of COVID-19, including 3.3 million deaths. With the aim of controlling viral transmission, many potential vaccines have been developed and rolled out at record speed. The majority of currently available COVID-19 vaccines contain SARS-CoV-2 spike protein as an immunogen and are based on plasmid DNA, mRNA, viral

The stress and anxiety brought on by the pandemic is leading to a lot of brain fog. Thankfully, there are ways to get your concentration back on track.
Feeling loopy? The coronavirus pandemic has continued to disrupt our lives and it has taken a toll on us emotionally, mentally and physically. A year of being isolated at home has made people more stressed, anxious and fearful of what the future may look like. Due to the social distancing measures in place, we haven’t been able to resume the activities we’re used to doing, so we’re not actively engaging our brains.
Sugary Drinks Tied to Spike in Colorectal Cancer By Kate Johnson
May 10, 2021 Drinking too many sugar-sweetened beverages in adolescence and young adulthood could partially explain the recent rapid rise in early-onset colorectal cancer at least in women, according to a new study.
The study found that women who recalled drinking two or more of these drinks each day in adolescence had a twofold increase in the risk of colorectal cancer before the age of 50, compared to those who had only one such drink per week or less.
However, experts warn the findings are based on small numbers and do not prove a direct connection.
Research in women under 50 years of age finds that drinking two or more sugary drinks per day is linked with double the risk of early onset colorectal cancer.
