According to AstraZeneca, the vaccination has been replaced by revised shots that address novel variations.
TTS is thrombosis with thrombocytopenia syndrome, which is a clot in blood vessels of the brain or elsewhere, along with a low platelet count
TTS has emerged as a rare but significant concern associated with the AstraZeneca Covid-19 vaccine
A doctor, however, emphasised that these findings don't change the fact that the vaccines were essential to fight COVID-19
Monkeypox outbreak: Social media posts claiming the chimpanzee adenovirus vector used in AstraZeneca's Covid vaccine, causes Monkeypox have surfaces, PTI reported.
Novavax Inc also said that early data showed its vaccine generated an immune response against Omicron
First identified last month in Southern Africa and Hong Kong, Omicron has rapidly spread across the globe
AstraZeneca's Covishield is largely used in India
The AstraZeneca antibody-drug cleared by the US Food and Drug Administration on Wednesday is different. It's the first authorised for long-term prevention against COVID-19 infection, rather than short-term treatment.
AstraZeneca has partnered with scientists at Imperial College London to develop a new vaccine technology to treat cancer, heart conditions
Imperial scientists had aimed to use the technology to design a COVID-19 jab
Foreign Secretary Harsh Shringla had earlier said that non-recognition of Covishield COVID-19 vaccine is a discriminating policy.
The system can draw 12 doses of the AstraZeneca vaccine in four minutes
The machine only works on AstraZeneca multi-dose vials currently
Oxford researchers have claimed that Pfizer, AstraZeneca COVID-19 vaccines are less effective against Delta variant
They, however, said that these vaccines still offer good protection against new infections
A study has found a syndrome linked with AstraZeneca vaccine that has high fatality risk
The occurrence of blood clot syndrome is very low
The syndrome affects even the young and healthy
The findings based on data from over 600 people aged 18 and above were consistent across all groups of people regardless of age, chronic illnesses or sex, according to the researchers.
The UCL Virus Watch study also found that antibody levels are substantially higher following two doses of the Pfizer vaccine than after two shots of the AstraZeneca preventive.
The authors highlight that although the clinical implications of waning antibody levels are not yet clear, some decline was expected
Moderna will become the fourth vaccine to be available for use in India
The Centre plans to provide the Moderna doses directly to states
Pfizer will supply one billion doses to India within this year
About 5 million people in Britain are thought to have had the vaccine made by Serum Institute in India
India saw a single-day rise of 46,617 new coronavirus infections
The death toll due to COVID-19 rose to 4,00,312 with 853 daily fatalities
AstraZeneca tests booster dose called AZD2816 for protection against the 'beta variant' of the COVID-19 virus
Beta variant originated in South Africa
The current vaccines available against COVID-19 are believed to be less effective against the Beta variant.
This new booster COVID-19 vaccine, developed by AstraZeneca, is known as AZD2816.
The research investigated SARS-CoV-2 transmission, infection outcomes, and immunity in residents and staff in long-term care facilities in England for adults aged 65 years and older since June 2020.
This study was completed before the emergence of the Delta variant of SARS-CoV-2 now dominating in the UK.
However, even beyond four weeks, a single vaccine dose does not eliminate infection risk.
Two doses from either the Oxford/AstraZeneca or the Pfizer vaccine are over 80% effective in preventing infection from B1.617.2 variant of COVID-19
The UK findings are said to be based on data from PHE and have also revealed that the two doses provide 87% protection from the B.117 variant
Professor Andrew Pollard said the immunization policy in Britain and India should not be compared because of the different circumstances in the two countries.
“An immunization policy that aims to vaccinate the largest number of people in the quickest possible time with at least one dose makes sense in the present circumstances in India,” Pollard said.
AstraZeneca COVID vaccine may be linked with a small risk of low blood platelets, says a new study
The study was conducted by researchers at the University of Edinburgh in the UK
