New Delhi. Corona’s new variant Omicron has created a stir at this time. Continuous research is going on about how effective the vaccine is against Omicron. A new study conducted by researchers at the University of Oxford has found that a booster dose of the AstraZeneca vaccine is effective against Omicron. The AstraZeneca vaccine is available in India under the brand name Covishield.
The study found that the AstraZeneca vaccine was able to fight against Omicron one month after the third dose. Whereas against the delta variant, this vaccine is effective only after the second dose. Covishield accounts for more than 85 percent of all vaccines delivered in India. For this reason, it is not considered an ideal vaccine for a booster dose.
Earlier, a research had also come from America regarding the effect of the vaccine against Omicron. Initial research indicates that most vaccines are also not effective against it. The only relief is that people taking the vaccine are not getting more seriously ill after getting infected with Omicron. Such people are surviving Omicron infection who have taken Pfizer and Moderna vaccines along with a booster dose. But now the name of AstraZeneca has been added to it.
Three months after two doses of Oxford-AstraZeneca’s Kovid-19 vaccine, its protection decreases. This has been claimed in a study published in the Lancet journal. The findings, drawn from data from Brazil and Scotland, suggest that people vaccinated with AstraZeneca need a booster dose to protect against serious disease. AstraZeneca vaccine is known as Covishield in India. Researchers analyzed data on 2 million people in Scotland who had received the AstraZeneca vaccine and 42 million in Brazil.
