Covid-19 Omicron variant was first detected in South Africa. The large-scale analysis of Pfizer vaccine effectiveness seems to support early indications that the the vaccine shot effective against Omicron like Delta variant.
The information was shared during a recent meeting of the Delhi Disaster Management Authority, which devises COVID-19 management policies for the capital.
The B.1.617.2 or Delta variant was first observed in India in late 2020. It has since spread around the globe.
Some of the patients infected with the Delta plus variant of coronavirus were fully vaccinated
This is Maharashtra's second death from the Delta Plus after an 80-year-old woman from Ratnagiri died last month.
Covid explained: B.1.617.3, a relative of the Delta variant; B.11.318, which contains 14 mutations; Lambda, a variant discovered by Public Health England and classed as a VOI by the WHO; and Kappa or B.1.617.1 are among the variants.
While the constant fall in the number of fresh cases and the TPR is a huge relief for health planners, the fact that the virus is remaining active in the body of the infected for much longer than usual is a big cause for concern.
Regions with high vaccination and strong public health measures, such as Singapore, continue to do well, INSACOG noted.
The variant is also around 40-60 percent more transmissible than its predecessor, Alpha variant, and has already spread to more than 80 countries, including the UK, the US and Singapore.
A person can develop immunity – the ability to resist infection – in two ways: either after being infected with coronavirus or by getting vaccinated.
Globally, cases of the Alpha variant have been reported in 178 countries, territories or areas, while 123 countries reported cases of the Beta variant, 75 countries reported cases of the Gamma variant.
Lambda Covid variant explained: The variant, also known as the C.37 strain, was first detected in Peru in August 2020.
Dr. Siddharth Shiv Jaiswal, MD of NHM Tripura had reconfirmed that 91 per cent of 151 samples sent for genome sequencing test outside the state have found Delta Plus variant of the virus
According to the Union Health Ministry the Kappa Covid variant is not a new variant and it has been present in the country since February.
Genome sequencing of 109 samples done at King George's Medical College revealed 107 cases of Delta Plus variant and two cases of Kappa Variant.
Strict restrictions were imposed on travelers from India and some other countries because of the rise of the contagious delta variant of the coronavirus.
Disagreeing with the presence of cases from the lethal Delta Plus variant of coronavirus, the Delhi Health Minister mentioned that no communication on this matter has taken place between the Delhi government and the Centre.
Results of two studies of blood serum from people who had received Covaxin suggest that the vaccine generates antibodies that effectively neutralise both Alpha and Delta variants of coronavirus.
