The study also stated that Delta variant was 30-70% more transmissible than previous SARS-CoV-2 lineages & the 2020 Covid outbreak in Delhi was unrelated to any variant of concern.
New variants like Delta, which are more transmissible and have been shown to evade protections in some cases, are moving the bar for herd immunity near impossibly high levels.
Experts say the biggest mistake was allowing the virus to travel freely into the rural areas, adding that eradication of the virus now is too far-fetched an idea.
While Covid-19 has been a catastrophe, it’s also an unprecedented opportunity, given the visible public health ravages, to change minds and prove the value of vaccines.
AIIMS director Randeep Guleria said one should not think of herd immunity in 'practical terms' in India, especially in the times of 'variant strains' of Covid-19 and varying immunity.
Covid-19 in Manaus peaked in April-May 2020 and then developed a supposed 76% herd immunity by October, but the Brazilian city is now besieged by a second wave.
Evidence is compelling that a robust and rapid vaccination campaign could render Covid less of a threat than seasonal flu through building herd immunity.
Driving this wave of interest is the upcoming Rising North-East Investors Summit in New Delhi, organised by the Ministry for Development of the North Eastern Region.
India used multiple types of aircraft, air to surface missiles & air defence systems to inflict damage to PAF. Almost all strikes were covered by high-res recon UAVs & satellites.
Pakistani establishments and their proxies are prone to severe, predictable 7-year-itch. Each step up the escalation ladder buys India about this many years of deterrence on average.
