Broad COVID vaccine designed with AI tested in humans for the first time

An experimental vaccine designed with the help of artificial intelligence has passed its first human trial. It was found to be safe and well-tolerated, but it is still too early to know whether it will protect against a broad family of coronaviruses.

Do Corona Vaccines Increase Cancer Risk? The Korean Study That Claimed This Did Not Prove a Causal Link

A new study supposedly found a link between coronavirus vaccines and an increased risk of cancer. In fact, the study has fundamental flaws and does not prove causation – and other studies have not found such a link.

Study: High-dose flu vaccine linked to nearly 55% reduction in Alzheimer's risk

An analysis of data from nearly 200 people aged 65 and over found that a high dose of flu vaccine was associated with a lower risk of Alzheimer's, especially in women. * The researchers emphasize that

Dr. Yotam Bar-On: “Why do viruses always win?” – and what gives us an advantage anyway

In a lecture at the Technion, Dr. Yotam Bar-On explained how rapid evolution, mutations, and immune evasion allow viruses to outpace the immune system, why vaccines are very successful in some diseases and less so in others, and what we learned from the Corona era.

Breakthrough: fMRI brain training increased antibodies after hepatitis B vaccination

A study by Tel Aviv University, the Technion, and Ichilov in Nature Medicine found that positive anticipation that activates the VTA region of the reward system is associated with a stronger immune response in humans.

Vladimir Khabkin: Fighter against cholera, speech and assimilation

The Jewish-Russian bacteriologist and immunologist who developed vaccines for cholera and tuberculosis, led the fight against epidemics in India, and worked to preserve Jewish identity (although he recommended that the yeshivots he donated to teach students practical subjects) alongside extensive philanthropy.

Double whammy: NIH budget cuts and elimination of preventive medicine threaten public health in the US and around the world

New study warns that the sharp cuts to the NIH and Kennedy's desire to dismantle the body of recommendations for preventive medicine could lead to an increase in morbidity, distrust in the medical establishment, and dependence on expensive and inaccessible medicine

US science agencies under attack: grants are being cut, journal subscriptions are being canceled, and NSF headquarters is being closed

Science magazine reports on a series of decisions by the Trump administration that are harming American science – favoring artificial intelligence and quantum computing, excluding life sciences, and cutting support for groundbreaking research are sparking a wave of protest in the community.

Within two decades, the US lost its leadership position to China. From leading of 45 critical technologies to just five

Data analyzed by the Australian ASPI Institute shows that leadership in these technologies has shifted to China. One area in which the US still dominates is vaccine development, but this too is at risk due to the cutbacks.
Researchers analyzed the ability of three different types of milk – breast milk, cow's milk, and artificial formula – to increase intestinal permeability to nanoparticles and macromolecules, which could allow for the future ingestion of RNA vaccines and drugs.

Drinkable Vaccination

Researchers at the Technion are developing a platform that will allow vaccines and drugs to be consumed by swallowing instead of by injection. Inspiration: Breast milk

Nobel Prize in Medicine 2023 for the pioneers in the field of mRNA who accelerated the vaccines for Corona

Kariko and Weissman immediately realized that their discovery was of enormous significance for the possible use of messenger RNA in medicine. These important findings were published in 2005, 15 years before the outbreak of the Corona epidemic.

Fear of an outbreak of monkeypox

Several cases of the viral disease have been discovered in the United States and Europe and health authorities are preparing to stop its spread. The good news: there is an effective vaccine against it

A thorough study of 1.2 million general insureds proves: the corona vaccine is effective

Final results of the Klalit Research Institute regarding the effectiveness of corona vaccines are published in the medical journal The New England Journal of Medicine: after the first vaccine dose: 57% effectiveness in preventing morbidity and reducing

About the Helsinki Committee - and the dance about the two weddings

In recent days there has been a big uproar regarding the Helsinki Committee, what it determined or did not determine, and what it means for the vaccine. So let's break down the issue, to understand what the Ministry of Health really did wrong, and what

The connection between the flu vaccine in pregnancy and autism in the offspring has been ruled out

A flu vaccine during pregnancy protects the children and women from illness, but does it also have long-term risks? A decade-long follow-up study refutes this.
