New estimate of total immunity to SARS-CoV-2 in Texas

According to researchers in Texas, a lack of appropriate testing in the US has led to an underestimation of seroprevalence in the U.S., thus making it difficult to estimate population immunity to SARS-CoV-2 or vaccination. While model-based estimation has been proposed, the calculations are based on inputs such as viral reproduction number, immune response longevity,

Prevention of SARS-CoV-2 virus spread through aerosols

As the development of the COVID-19 pandemic to date has shown: aerosols contribute significantly to the occurrence of infection – and combating them can significantly reduce a resurgence of infection levels. The question of effective protective measures will become acute in the autumn, if not before: seasonal factors, new virus variants, declining immunity after vaccination

We need herd immunity against COVID-19 vaccine misinformation

Misleading claims about COVID-19 vaccines can negatively impact public confidence in immunisation uptake, a new UNSW Sydney study reveals. A new study published in the scientific journal PLOS ONE revealed over 103 million people globally liked, shared, retweeted or reacted with an emoji to misinformation and conspiracy theories about COVID-19 vaccines. In 2020, a social

Dengue virus immunity may protect children from Zika symptoms

Previous infection with dengue virus may protect children from symptomatic Zika, according to a study published January 22 in the open-access journal PLOS Medicine by Eva Harris of the University of California, Berkeley, and colleagues. Zika virus emerged in northeast Brazil in 2015 and spread rapidly across the Americas, affecting populations that have been largely

Research reveals link between immunity, diabetes

When it comes to diet-induced obesity, your immune system is not always your friend. Adipose (fatty) tissue is infiltrated by white blood cells that have been linked to the development of inflammation, insulin resistance and type 2 diabetes. How this happens is complicated and under intense investigation by researchers around the world. Now, from a

Glycans at the ‘I’ of the storm in humoral immunity and melanoma progression

Two new studies have unveiled how a peculiar molecule impacts how antibody-producing cells develop and function as well as how normal melanocytes progress to melanoma malignancy. “These findings on fundamental immunology and melanoma development originate from totally different areas of research, though have intersected at the bench,” said Charles Dimitroff, Ph.D., of the Department of

CDC Monitoring Measles Outbreak In 21 States

The Center for Disease Control and Prevention is monitoring the outbreak, one of the worst in several years. More than 107 people in 21 states have contracted measles since July 18 of this year, reports the Center for Disease Control and Prevention. If this pace keeps up, it could be the worst outbreak since 2014,

Maternal dengue immunity protects against fetal damage in mice following Zika infection

Dengue and Zika viruses are closely related and carried by mosquitos. In infested subtropical and tropical areas, dengue transmission often precedes Zika virus (ZIKV) infection, suggesting that women who previously acquired dengue immunity may be bitten by ZIKV-carrying mosquitoes during pregnancy. Whether that mother’s prior dengue immunity would protect her unborn baby from devastating brain
