Three million face masks are thought to be thrown away every minute, research suggests.

In June 2020, researchers at the University of Aveiro in Portugal estimated that 129 billion face masks are used monthly across the world.

Experts at the University of Denmark have described the worrying statistic, which amounts to three million face masks a minute, as a ‘ticking time bomb’.

In the paper, titled Preventing masks from becoming the next plastic problem, scientists said the world must ‘urgently recognise this potential environmental threat’.

One key factor which could be contributing to the problem is that face coverings are a new phenomenon in most countries across the world. While we are quite used to recycling items such as plastic bottles, there is no official guidance on mask recycling. Researchers said this makes it more likely that they would be disposed of as solid waste.

Drug makers are increasingly turning to monoclonal antibodies to protect the millions of people who can't use vaccines. But questions swirl about their cost and long-term viability.

As the COVID-19 vaccine rollout gathers pace, a population is at risk of being left behind: the millions of people around the globe who lack fully functional immune systems.

While the exact number of the immunocompromised worldwide is unknown, estimates suggest that about 10 million live in the U.S. alone, or around 3 percent of the national population. The number encompasses a diverse range of vulnerabilities, including rare genetic immune deficiencies, chronic illnesses that impair the immune system such as rheumatoid arthritis, and cancer and organ-transplant patients who must take immune-suppressing medications.

For them, vaccines will not be effective, because they are incapable of making their own antibodies to neutralize the SARS-CoV-2 virus. Instead, pharmaceutical companies around the world are racing to develop alternative treatments that bypass the immune system altogether.

The most common option is called monoclonal antibody treatments. These artificially generated antibodies mimic the body’s natural immune response by binding to key sites on the virus’ spike protein, preventing it entering cells and reproducing. Companies including AstraZeneca, Regeneron, and Eli Lilly are currently testing whether monoclonal antibodies can protect immunocompromised people from SARS-CoV-2.
