Maybe Don’t Unleash the Kraken
(The Atlantic) These days, it’s a real headache to keep tabs on the coronavirus’s ever-shifting subvariants. BA.2, BA.4, and BA.5, three Omicron permutations that rose to prominence last year, were confusing enough. Now, in addition to those, we have to deal with BQ.1.1, BF.7, B.5.2.6, and XBB.1.5, the version of Omicron currently featuring in concerned headlines. […]

Vaccines are not making COVID strains like ‘Kraken’ stronger. Here’s how the four shots battle variants
(Fortune) Scientists are keen to shut down the idea that vaccines are making COVID strains “stronger” and that those who have had a booster are more susceptible to the disease. The World Health Organization has confirmed that XBB.1.5—dubbed “Kraken” by biology professor Ryan Gregory—is the most transmissible strain yet. The Centers for Disease Control and […]

COVID-19 vaccines: From nasal drops to a redesign, what 2023 could have in store
(CBS News) Several vaccine companies say they are expecting breakthroughs as early as this year as they pursue new ways to protect people against SARS-CoV-2, the virus that causes COVID-19. The Food and Drug Administration is set to convene a panel of its outside vaccine advisers later this month to weigh key issues over the future of COVID-19 […]

COVID Autopsies Reveal The Virus Spreading Through The ‘Entire Body’
(ScienceAlert) Dozens of recent autopsies show persistent evidence of SARS-CoV-2 throughout the body, including in the lungs, the heart, the spleen, the kidneys, the liver, the colon, the thorax, muscles, nerves, the reproductive tract, the eye, and the brain. Related Study in Nature

Study Finds There Are 4 Subtypes of Long COVID
(Prevention) Research has found that long COVID impacts one in five adults under the age of 65, but scientists are still trying to learn more about the condition. Now, a new study has found there are actually four main subtypes of long COVID. The study, which was published in the journal Nature Medicine, used machine learning to analyze clusters of symptoms […]

Data-driven identification of post-acute SARS-CoV-2 infection subphenotypes
(Nature) The post-acute sequelae of SARS-CoV-2 infection (PASC) refers to a broad spectrum of symptoms and signs that are persistent, exacerbated or newly incident in the period after acute SARS-CoV-2 infection. Most studies have examined these conditions individually without providing evidence on co-occurring conditions. In this study, we leveraged the electronic health record data of […]

Full protection from SARS-CoV-2 brain infection and damage in susceptible transgenic mice conferred by MVA-CoV2-S vaccine candidate
(Nature)Vaccines against SARS-CoV-2 have been shown to be safe and effective but their protective efficacy against infection in the brain is yet unclear. Here, in the susceptible transgenic K18-hACE2 mouse model of severe coronavirus disease 2019 (COVID-19), we report a spatiotemporal description of SARS-CoV-2 infection and replication through the brain. SARS-CoV-2 brain replication occurs primarily […]

A Vaccine Against COVID-19 Found to Protect Against Infection and Brain Damage Caused by the Virus
(Neuroscience News) Although the pathology of the respiratory system is the main impact of COVID-19, many patients also manifest important neurological symptoms, such as loss of smell (anosmia), headaches, malaise, cognitive loss, epilepsy, ataxia and encephalopathy, among others. However, this effect on the nervous system by the coronavirus has not been characterized in detail and […]

A survey of COVID-19 vaccine acceptance across 23 countries in 2022
(Nature) Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continued to mutate and spread in 2022 despite the introduction of safe, effective vaccines and medications. Vaccine hesitancy remains substantial, fueled in part by misinformation. Our third study of Coronavirus Disease 2019 (COVID-19) vaccine hesitancy among 23,000 respondents in 23 countries (Brazil, Canada, China, Ecuador, France, Germany, […]

Most people who ended up with long COVID started with a mild case, new study shows
(CBS News) Even mild COVID-19 cases can have major and long-lasting effects on people’s health. That is one of the key findings from our recent multicountry study on long COVID-19 – or long COVID – recently published in the Journal of the American Medical Association. Long COVID is defined as the continuation or development of symptoms three months after the […]
