Coronavirus: Experts warn against slow vaccinations as Delta variant spreads

India on Sunday reported over 1.14 lakh fresh COVID-19 cases, marking the lowest single-day spike in 60 days. The daily test positivity rate has also declined to 5.62%.

Only 3.3% fully vaccinated; Centre focuses on 'positive image'
This week, the Centre announced that India has administered at least one vaccine dose to more people compared to the United States. India has administered at least one dose to 18.32 crore people (13.4%) and just under 4.5 crore (3.3%) have been fully vaccinated. More than 50% of the US population has received at least one dose, while 13.7 crore people are fully vaccinated.
Variant
Partial vaccinations insufficient against Delta variant: Study
A recent study conducted by the INSACOG had said that prior infections and partial vaccinations were insufficient against the Delta variant of the SARS-CoV-2 (B.1.617.2), which had first originated in India. Another study, published in The Lancet, stated that the Pfizer-BioNTech vaccine is significantly less effective against the Delta variant, especially in cases involving partial vaccinations are larger gaps between the two doses.
Study
Pfizer single shot just 32% effective against Delta variant
The study said that after one dose of the Pfizer vaccine, 78% of people had a quantifiable neutralizing antibody response against the original strain. The efficacy slipped to 50% for the Alpha variant (B.1.1.7), 32% for the Delta variant, and 25% for the Beta variant (B.1.351). Experts now call for faster delivery of second vaccine doses to ensure full vaccinations.
