WHO: 90% Of Global Population Is Immune To COVID

NEW DELHI: According to the World Health Organization (WHO), at least 90% of people worldwide are currently resistant to COVID-19 infection. According to WHO director-general Tedros Adhanom Ghebreyesus, at least 90% of the world's population currently has some level of immunity against SARS-CoV-2 as a result of previous illness or immunisation.

The COVID pandemic's emergency phase is almost over, but it is not yet complete, according to the head of the WHO. Although we're still not there, Tedros said, "we are much closer to being able to say that the emergency phase of the pandemic is over."

According to him, "gaps in surveillance, testing, sequencing, and vaccination continue to create the ideal conditions for a new variant of concern to emerge that could result in significant mortality."

According to a previous study, a two-dose experimental vaccine can prevent severe Covid even a year after the shots. The outcomes might lessen the requirement for routine boosters and safeguard vulnerable groups, such as youngsters, whose immune systems are still developing.

In pre-clinical research, a team of researchers found that the Moderna mRNA vaccine and a protein-based vaccine candidate that contained an adjuvant—a substance that boosts immune responses—elicited long-lasting neutralising antibodies to the Covid virus during infancy.

"Following up on our SARS-CoV-2 infant rhesus macaque study, we gave the animals a high-dose challenge with a SARS-CoV-2 variant one year later to assess the durability of vaccine-induced immune responses and their efficacy," According to a report by the news agency, Dr. Kristina De Paris, a professor of microbiology and immunology at the UNC School of Medicine,

As per sources, the 2-dose vaccines continue to offer protection against lung disease in rhesus macaques one year after they were first immunized, according to a new study by the same team, which was led by researchers at the University of North Carolina at Chapel Hill, Weill Cornell Medicine, and NewYork-Presbyterian.
