Wreaking havoc once again across the globe, Omicron has emerged as a new concern. In such a situation, the question is whether the cover shield and vaccine are as effective against this new variant of Corona as they were against the delta variant. The new study shows that both doses of Covishield are not effective against Omicron. Earlier, the same report had come to the fore regarding Covaccine.
Overall, Omicron and its sub-variants can still make you very sick after taking both doses of both vaccines. In such a situation, a booster dose has been advised to avoid them. Experts at ICMR have also agreed that those who have reached the schedule for both Covishield and Covaccine doses should take a booster dose.
Inadequate Coveshield. In a study conducted against Omicron against
The Covishield vaccine has shown that the effect of Omicron is visible in a person even after taking both doses of this vaccine. Not only this, the new variant of Omicron BA.1 is affecting the body’s antibodies. But yes, antibodies can be effective against this variant to a large extent if a booster dose is taken.
ICMR also accepted
An ICMR scientist said that Omicron with the highest number of mutations in Spike affected immunity even after both doses of the vaccine. Omicron’s spike is more powerful than the Delta variant. However, studies in people who have taken the CoveShield vaccination show that it has stronger antibodies to fight the virus, but its effect has diminished after the Omicron version.
ICMR collected samples of 24 corona-infected persons 180 days after the second dose of Covishield. At the same time, samples of 17 people who did not have corona were also taken and they had taken both doses of Covishield. Omicron infection was found in these people even after taking two doses of Covishield.
What was the result
Serum samples of people were taken 14-30 days after corona infection. The complete genome could be obtained in only 21 cases out of 46 successful cases. Corona’s delta variant was confirmed in 17 people. While the Kappa variant of Corona was found in four.
The researchers later assessed the potency of these serum samples against BA.1, delta, beta, and Omicron variants. The results of which were astonishing. The samples showed that the antibody neutralized the BA.1, beta, and delta variants more effectively than Omicron. Compared to Omicron, the serum antibody concentration was found to be the lowest at 0.11. Whereas in other cases its average was 11.28 and 26.25.
It is worth noting that in November last year, the first case of the Omicron variant in the world was reported in South Africa.
