Oxford / AstraZeneca Vaccine 80% Effective Against Variant B1.617.2: UK Study | India News

LONDON: Two doses of Oxford / AstraZeneca or the Pfizer The vaccine is more than 80 percent effective in preventing infection from the B1.617.2 variant of Covid-19, first discovered in India, as reported, according to a new UK government study.
The Oxford / AstraZeneca two-dose vaccine is also being produced by the Serum Institute of India What Covishield and administered to the adult population of India to protect against the deadly virus.
The UK findings are said to be based on data from Public Health England (PHE) and have also revealed that the two doses provide 87 percent protection against the B.117 variant, first discovered in the Kent region of England and also considered highly transmissible.
According to the newspaper ‘The Telegraph’, the findings of the latest study were presented at a meeting of the government’s New and Emerging Respiratory Virus Threat Advisory Group (Nervtag) this week.
The latest PHE statistics released earlier this week show that the number of cases of the B1.617.2 variant increased by 2,111 over the past week to reach 3,424 cases nationwide.
“I think it’s clearly growing, which anybody can see in the numbers being reported week-by-week,” Dr. Jeffrey Barrett, director of Covid-19 genomics at the Sanger Institute, said at the time. BBC.
“If I had to guess today, it would be 20 or 30 percent instead of 50 percent (more infectious than the Kent variant). But there is still uncertainty, 50 percent could be the worst case,” he said. he said, referring to the rate of transmissibility of the variant of concern (VOC) first detected in India.
Meanwhile, PHE officials are also closely monitoring a variant under investigation (VUI) in the Yorkshire region of England, which shows high transmissibility.
Comes as the National Health service (NHS) further expanded its vaccination program and announced that it will open reservations for people aged 32 and 33, who will join the cohort of over 34 years, starting on Saturday.
NHS England said the third eligibility expansion in just a week comes when more than four in 10 adults have already had both strokes.
“Just days after we expanded the offering of a vaccine to 34- and 35-year-olds, we are now launching the invitation to 32- and 33-year-olds, an incredible step forward in the largest and most successful vaccination program in the history of the NHS. UK Health Secretary Matt Hancock said.
“This is truly a testament to the heroic work of our incredible NHS and care staff, volunteers and local authorities across the country who have helped deliver more than 50 million lightning-fast strokes across England, keeping us on track. right way to offer a vaccine to everyone in July ”, he said.
Meanwhile, the Department of Health and Social Care (DHSC) has said it is increasing sewage and sewage genome testing and sequencing along the way to track and trace all Covid-19 variants, including the B1 variant. .617.2.
A new laboratory was opened last month in Exeter, in the southwest of England, dedicated to the analysis of wastewater, making it one of the largest sewage water processing laboratories in the world. Increased genomic sequencing of wastewater samples is expected to provide more clues as to where the variants of interest may be circulating undetected in communities. You can collect evidence of variants from infected people and continue to monitor sewage after surge testing has finished in an area.
“Sequencing wastewater samples provides an additional detection system for variants of interest, allowing us to respond more effectively to outbreaks and better protect citizens,” said the executive director of the Sanitary Security Agency of the UK, Dr Jenny Harries.
“This innovative program supports the work of Public Health England and the NHS Test and Trace to help us understand where the virus may be circulating undetected,” he said.
Wastewater samples are taken from around 500 locations in England and sent to the laboratory at Exeter Science Park. Scientists from the Environment Agency analyze the samples to quantify the amount of Covid-19 present.
“As infections decline and we move beyond national restrictions, testing wastewater for variants early on is important to help local authorities and NHS Test and Trace act quickly to stop the spread of variants in communities.” said the program leader at the Joint Center for Biosafety, Dr. Andrew Engeli.
Experts said that without the need to rely on people to show up for swab testing, this type of monitoring in a catchment area can identify outbreaks in smaller areas and neighborhoods. There are also pilots who analyze wastewater from specific institutions, such as within the food supply chain and prisons.
