New Delhi: A recent study conducted by the Indian Council of Medical Research (ICMR) and National Institute of Virology (NIV) Pune, has found that those who recovered from the virus and have been administered with both doses of Covishield have higher immunity against the Delta variant.
For the study titled ‘Neutralization of Delta Variant with Sera of Covishield Vaccines and Covid-19 Recovered Vaccinated Individuals,’ neutralising antibody (NAb) responses of three types of people were accessed, Hindustan Times reported.
1. Individuals who were inoculated with two doses of Covishield.
2. Coronavirus-recovered individuals who were administered both doses of Covishield
3. Covid-19 recovered individuals who had contracted breakthrough infections such as Kappa and the Delta variants.
The study findings discovered that Covid-19 recovered individuals and the breakthrough cases had “relatively higher neutralising responses against the Delta variant in comparison to the participants who administered either one or two doses of Covishield.”
A comparative assessment of Covishield vaccinated individuals’ sera (n=116) in different categories was performed against the prototype strain B.1 (D614G) and the Delta variant of COVID-19.
It is a test that gauges the presence and number of antibodies in a person’s blood, the report added.
On the other hand, a recent Indian Council of Medical Research (ICMR) study has found that Covaxin is effective against the Delta Plus variant. Last week, Union science and technology minister Jitendra Singh said that as many as 70 cases of Delta Plus variant were detected by INSACOG, a cluster of labs that do genome sequencing.
