Israel, with the highest proportion of citizens vaccinated against Covid-19 in the world, found it took three weeks for the Pfizer Inc.-BioNTech SE shot to start curbing new cases and hospitalizations.
The results are all the more striking, experts said, because Israel is contending with a worrisome new variant of the coronavirus. The variant B.1.1.7 now accounts for up to 80 percent of the samples tested in Israel.
First identified in Britain in December, the variant has spread to 72 other countries and may be up to 50 percent more transmissible than other variants.
Israel leads the world in vaccinating its citizens. So far, more than a third of its population of more than nine million people has received a first dose of the Pfizer-BioNTech vaccine and nearly two million people have received a second dose.
Study shows that human hormones also follow a seasonal pattern
Our minds may be affected by winter s long nights or spring s flowers, but what about our bodies? A new study at the Weizmann Institute of Science reveals that our hormones also follow a seasonal pattern.
By analyzing data on several types of hormones from millions of blood tests, the researchers discovered that some hormones peak in winter or spring and others in summer.
This research, which was published in the
Proceedings of the National Academy of Sciences (

As many of the world’s scientists and medical researchers battle to control the COVID-19 pandemic, others are racing to develop groundbreaking new ways to defeat another major disease: cancer.
According to the World Health Organization (WHO), the pandemic has had a significant impact on the fight against cancer, delaying diagnoses as well as hampering access to life-saving treatments. In a survey conducted in 2020, the WHO found that cancer treatments were disrupted in more than 40 percent of countries over the course of the year. To make matters worse, people with cancer also are at a higher risk of becoming seriously ill from the coronavirus.
