Dr. Aaron Kheriaty, a University of California-Irvine psychiatry professor, felt he didn’t need to be vaccinated against covid because he’d fallen ill with the disease in July 2020. So, in August, he sued to stop the university system’s vaccination mandate, saying “natural” immunity had given him and millions of others better protection than any vaccine

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,

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

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

Moderna begins coronavirus vaccine trials on children Should parents feel safe getting their kids inoculated? Reaction from Fox News medical contributor Dr. Janette Nesheiwat. At least one midwestern state could see coronavirus herd immunity by this summer, according to a health official there.  Julie Willems Van Dijk, the deputy state health secretary in Wisconsin, said

India is perhaps moving towards herd immunity as Covid-19 cases are declining and there is no need to panic over the new virus strain found in the United Kingdom because reports suggest that it not as virulent, doctors said at a webinar on Thursday. The webinar ‘HEAL-Thy Samvaad’ was organised by the Heal Foundation to

Using antibodies from recovered patients has been life-saving for other acute infections and should be explored in response to COVID-19, researchers say in the International Journal of Risk & Safety in Medicine. The worldwide COVID-19 pandemic has infected more than 4 million people and killed close to 280,000. Finding a vaccine has become a global

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

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

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

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,

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
