‘Delta’ Variant Predominant Even After COVID-19 Vaccine Doses: AIIMS Study
Updated On Jun 10, 2021
All India Institute of Medical Science (AIIMS) Delhi has conducted a preliminary study, the results of which showed the presence of COVID-19 Delta variant (B1.617.2) even after the doses of COVID-19 vaccine (single as well as both doses). The study was done on 63 people who got infected with the virus again after getting vaccinated. While no case of death has been reported among them, the study claimed that the variant is predominant in reinfection cases. As the study says, getting vaccinated for COVID-19 is not a guarantee to stay protected against the virus. Instead, it only ensures that the infection does not get severe. The same was emphasized by experts before.
Key Highlights of the Study
Amongst 63 people, 35 received both the doses of COVID-19 vaccines and 27 received only a single dose. All of them got infected with COVID-19 after vaccination and among samples, the Delta variant has been found predominant. The samples were genome sequenced.
1. Out of 63 samples, 36 were sequenced, of which 19 got single doses and 17 got both doses.
2. In 23 out of 36 samples, the Delta variant was found.
3. Out of 63 members who participated, 10 received Covishied whereas 53 received Covaxin.
4. The average age of the participants was 37 years, of which 41 were males and 22 were females. The participants were aged between 21 years and 92 years.
5. AIIMS earlier assured that there were no deaths in the group of participants. This indicates that the vaccine reduces mortality.
Commenting on the prevalence of Delta variant, the study also stated that vaccine breakthrough infections and reinfections are rare. Also, genomic sequencing of vaccine breakthrough infections can provide a deeper understanding.
The Delta variant was the reason behind India’s second wave of COVID-19 and is said to be more infectious than the first variant found in the UK.
