New Delhi. The delta variant of Kovid-19 can infect even after taking both doses of Covishield and Covaxin. It was first found in India in October. According to the report, this has been revealed in separate studies by AIIMS Delhi and National Center of Disease Control. However, both these studies have not yet been reviewed. According to an AIIMS study, the delta variant is 40 to 50 percent more infectious than the alpha variant found in the UK. This is the reason for the increase in corona cases in India.
In India, breakthrough infections due to the delta (B.1.617.2) variant have been reported after both Covishield and Covaccine vaccines. In India, two studies have been done on breakthrough infection in the vaccine of Covaxin and Covishield.
Both studies have found that the delta variant is capable of breaking through infection in people taking both the vaccine CovaShield and the Covaccine. AIIMS and CSIR IGIB found in the study that both alpha and delta variants had breakthrough infections, but more than delta, in people vaccinated with Covaccine and Kovishield.
The AIIMS-IGIB Study is an analysis of the condition of 63 symptomatic patients who were admitted to the emergency ward of the hospital after complaining of high fever for 5-7 days. Of these 63 people, 53 were given a dose of Covaccine and the others a single dose of Covishield. While 36 people had been given both doses of the vaccine. 76.9 percent of the cases of delta variant infection were recorded in people who were given a single dose of the vaccine. While 60 percent of those who took both doses were infected.Also read- Know the answer of the company making the vaccine on the study that made more antibodies than Kovishield
The data of the study also shows that people who were given Kovishield were more infected with the infection of the delta variant. The study also shows that delta variant infection occurred in 27 patients who had received the vaccine, their infection rate was 70.3 percent.
Can protect against alpha variant
Data from both studies shows that Covishield and Covaccine protect against the alpha variant of the infection, but not in the same way as it was when the first cases were detected in India. Both studies also indicated that the vaccine ‘Delta’ and even ‘Alpha’ may reduce protection, but the severity of the infection in each case does not affect the outcome.

This is in line with the scientists’ view that there is no evidence yet that the ‘delta’ variant is causing a higher number of COVID-associated deaths or more severe infections.
Studies indicate that Covaccine protects against both delta and beta variants. The beta variant was first found in South Africa.
A study conducted last week by scientists from NCDC and the Indian SARS COV2 Genomic Consortia indicated that the ‘delta’ variant was behind the second Covid wave in India. In early May, at the peak of the second wave of Kovid, more than four lakh new cases were being reported in the country every day.
