The WHO and its Technical Advisory Group on COVID-19 Vaccine Composition (TAG-CO-VAC) continue to regularly assess the impact of variants on the performance of COVID-19 vaccines to inform decisions on updates to vaccine composition.

WHO chief Tedros Adhanom Ghebreyesus has also warned of the ongoing impact of Long Covid, which provokes a long line of often severe and debilitating symptoms that can drag on for months or years.

According to the bulletin, BA.2.75 and BA.2.10 were also circulating but in lesser extent.
-
It also found that worldwide seroprevalence estimates varied from 7.3 per cent in the first wave of the COVID-19 pandemic to 37.6 per cent in the fifth wave and 56.6 per cent in the sixth wave.
-
A recent preprint (a study yet to be peer-reviewed) claims to have identified possibly unusual sequence patterns in the SARS-CoV-2 genome.
-
Existing drugs aimed at treating COVID-19 address symptoms of the virus but do little to quell viral shedding.
-
The recent outbreak of the disease has been reported from four states in the country
-
As per recent studies, the BCG vaccine -- originally for tuberculosis (TB), can provide protection against COVID-19, and several infections such as leprosy and malaria.
-
The vaccine was well tolerated with no significant safety concerns and a seroconversion rate of 91%
-
They also opined that the virus will likely circulate globally, with other prevalent respiratory viruses like influenza. It was also stated by them that this scenario almost certainly necessitates the same level of annual consideration for vaccine composition revisions.
-
Responding to a question in Lok Sabha, Minister of State for Science and Technology Jitendra Singh said 17 COVID-19 bio-repositories have been notified by the government.
-
Betacoronaviruses are being seen as a major threat to humanity and the current way of life and public health experts feel that vaccines could be a crucial tool to fight them as they emerge.
-
The government said that laboratory will be able to access even remote and forested areas where specially trained scientists from the ICMR can investigate outbreaks using samples from humans and animal sources.
-
The first reports of Deltracon emerged from Cyprus earlier this year but were dismissed as result of possible contamination of samples. Scientists around the world, including in India, however are now closely watching whether Deltacron can pose fresh threat.
-
From testing to treatment, Pune-based Mylab believes the time has come to adopt an integrated approach and deliver products needed from the patient’s perspective. MD Hasmukh Rawal lays out the company’s plans.
-
Further, reactogenicity after vaccine and placebo was minimal and comparable, and no serious adverse events were reported, the company said referring to the trial results.
-
The research, published in the Journal of the American Medical Association (JAMA), shows that a breakthrough infection generates a robust immune response against the Delta variant.
-
The findings, published in the journal Nature on Tuesday, also show that those infected with the virus prior to vaccination exhibit a more robust immune response to all variants than those who were uninfected and fully vaccinated.
-
A vaccine booster is the injection of an additional dose, intended to maintain immune protection against a given pathogen.
-
Writing in the journal Nature Communications, researchers in Australia said the tool was effective against viral transmissions in lab tests, adding that they hoped to begin animal trials soon.
-
Over the past few weeks, statements from the White House and the G7 have spurred renewed interest on how SARS-CoV-2, the virus that causes COVID-19, may have developed. Here's a breakdown of the various theories, including the one that it leaked from a Wuhan lab.

Drafted by a team of World Health Organization-appointed international experts and Chinese counterparts, the report has been keenly anticipated ever since investigators left China more than a month ago.
-
In the current study, published in the journal Science Signalling, the scientists focussed particularly on short strings of amino acids called short linear motifs (SLiMs), which are involved in transmitting information between the inside and outside of cells.
-
The government will maintain all the genomic sequencing data in its national database at two sites including West Bengal's National Institute of Biomedical Genomics and New Delhi's Institute of Genomics and Integrative Biology.
