Deep in Israel’s Negev Desert, Human Travel to Mars Comes Closer to Reality

With its red and yellow rock formations, the Ramon Crater in Israel’s Negev desert has been compared to the surface of Mars. Now, scientists are using the landscape deep in the desert for experiments to help make human travel to Mars a reality. Six astronauts from around the world recently spent a month simulating a mission to Mars, living in a special habitat built to resemble a spaceship, conducting scientific experiments, and exploring the terrain that resembles the red planet. For VOA, Linda Gradstein and Ricki Rosen visited the mission in the crater.

Britain Expands COVID-19 Booster Availability to Ages 40-49 

The British government Monday announced Monday an expansion of the nation’s COVID-19 booster shot program to people ages 40 and up, to fight off a potential winter surge of the deadly disease.

Until now, only British residents ages 50 and up, those clinically vulnerable because of underlying conditions, and frontline health workers were eligible for booster shots. But at a news briefing in London, the chairman of Britain’s Joint Committee on Vaccination and Immunization, Wei Shen Lin, announced the extension to those ages 40 and up who have been fully vaccinated for at least six months.

He said, as with the original booster program, either the Pfizer-BioNTech or Moderna vaccines can be used as the booster dose, regardless of the type of vaccine originally received.

The committee also recommended a second dose of the Pfizer-BioNTech COVID-19 vaccine for young people between the ages of 16 and 18. In August, the committee had advised only one dose of the vaccine for people of that age group, but would review the data, and were anticipating that a second dose may well be advised. Monday, the committee chairman said that was “indeed the case.” 

The chief executive of Britain’s drug regulator, the Medicines and Healthcare products Regulatory Agency (MHRA), Dr. June Raine, said they had closely monitored the use of the vaccines in people under 18, and their use raised no additional safety issues specific to this age group. 

Speaking via video conference, British Deputy Chief Medical Officer Professor Jonathan Van-Tam said the data so far showed that adults over age 60 who have received the booster were achieving over 90% protection against symptomatic illness and he expected protection against hospitalization and death to be even higher. 

He said if the booster program is successful and participation numbers are high, it would “massively reduce the worry about hospitalization and death due to COVID at Christmas and for the rest of this winter, for literally millions of people.”

Pakistan Begins Immunizing Millions Against Measles and Rubella 

Pakistan rolled out a massive two-week drive Monday to immunize more than 90 million children in what officials hailed as one of the world’s biggest vaccination campaigns against measles and rubella.

An official announcement said children aged between 9 months and 15 years across the country will be inoculated against the contagious viral infections.

The Pakistani government has mobilized more than 600,000 health professionals, vaccinators and social mobilizers for the campaign with the support of Gavi, the Vaccine Alliance, the United Nations Children’s Fund and the World Health Organization.

“Measles and rubella are contagious diseases and can have severe complications for children even death,” said Dr. Faisal Sultan, special assistant to the Pakistani prime minister on health.

“I urge both the front-line workers to work with dedication and the caregivers to express their support by vaccinating their children against the diseases,” Sultan added.

Officials said Pakistan has experienced an alarming rise in measles cases in recent years, affecting thousands of children and claiming many young lives.

“The measles and rubella campaign will move us not only one step closer to maintaining measles elimination and accelerating rubella control, but also one step closer to reducing the overall child mortality across Pakistan,” said WHO Country Representative Palitha Mahipala.

UNICEF said children under the age of five will also receive polio drops during the campaign to support Pakistan’s eradication efforts against the crippling disease. 

“Today’s world is still grappling with the very contagious measles and rubella viruses, none of which have gone away despite being entirely preventable with a simple vaccine,” said UNICEF Country Representative Aida Girma in remarks during the launch of the vaccination campaign in Pakistan.

The WHO says more than 140,000 people died from measles in 2018 worldwide – mostly children under the age of 5 years, despite the availability of a safe and effective vaccine.

Measles is caused by a virus in the paramyxovirus family and it is normally passed through direct contact and through the air.

WHO experts say there is no specific treatment for rubella but the disease is preventable by vaccination.

The rubella virus is transmitted by airborne droplets when infected people sneeze or cough. Humans are the only known host.
