01 :- How effective are COVID vaccines against the new variants?
Since the flare-up of the novel Covid, the world has stayed in a condition of frenzy and disarray. While at first the manifestations and the drawn out impacts of the lethal infection unleashed ruin in and all throughout the planet, with the beginning of the new COVID variations, the circumstance has declined and turn out to be more perilous. All things considered, the immunization rollout has been viewed as a beam of expectation and millions have effectively made their COVID effort. Be that as it may, the inquiry actually stays with respect to whether the antibodies are compelling against the new variations or not? This is what specialists need to say.
02 :- New COVID variants: What is it?
COVID-19 or SARs-COV-2 is a large family of viruses that have existed for a long time. While it has been over a year now, since the novel coronavirus impacted us, the first known strain of the virus which had been named “VUI 202012/01”, was discovered in the south-east of England. According to the scientists in the United Kingdom, the Kent variant was said to comprise a genetic mutation in the “spike” protein that could be the cause of immediate and easy spread of the virus amongst people.
The South African virus named 501Y.V2, was reported on December 18, in South Africa. Akin to its UK variant, the South African mutation was also said to be more transmissible and contagious. P.1 or the Brazillian variant was the first detected in early January 2021 in travelers from Brazil who were tested upon entering Japan. These include some of the key spike protein mutations present in both the variants discovered in the U.K. and South Africa.
03 :- India's battle with the double mutant coronavirus mutation
India is likewise fighting the beginning of the 'twofold freak' variation which was as of late found in the country.
A twofold freak variation alludes to the converging of two transformations of an infection strain that proceed to frame a third, very irresistible strain. The first instance of twofold change in Quite a while was found in the territory of Maharashtra.
With the assistance of genome sequencing and test testing, researchers have had the option to identify a sharp ascent in the E484Q and L452R transformations since December. It is accepted that the twofold freak variations can outperform the insusceptible framework and be exceptionally impervious to antibodies.
04 :- Covishield and Covaxin: Can they protect against the new variants?
According to the Indian authorities, both Covishield and Covaxin vaccines are effective against the UK and the African strain is still in process.
After sequencing 11,064 genome samples, it was found that the Kent variant was discovered in 807 cases, whereas the South African variant in 47 and the Brazilian variant was found in 1.
As per Balram Bhargava, ICMR Director-General, "Both the vaccines - Covishield and Covaxin- are effective against the UK and the Brazillian variants and the work against the South African variant is ongoing at several laboratories.
Union Health Secretary Rajesh Bhushan said states have been asked to ramp up testing, with focus on RT-PCR tests. Besides, the authorities have also asked states to isolate any infected person, strengthen public and private healthcare resources. Apart from that, proper social distancing and use of masks is suggested by the Center. Immediate vaccination process is also recommended for all eligible age groups.
05 :- Are COVID vaccines effective against the new variants?
As per an investigation led by the National Institute of Allergy and Infectious Diseases (NIAI), the Covid antibodies can secure against the new COVID variations. The exploration, driven by NIAID staff researcher Andrew Redd, assessed and broke down the white platelet tests of 30 individuals who were tainted by the COVID-19 infection and recuperated from it preceding the development of the variations in various pieces of the world. It was tracked down that the T-cells stayed dynamic against the infection and its reactions remained to a great extent unblemished and could perceive basically all changes in the variations contemplated, according to the specialists.
"While bigger investigations are required, the specialists note that their discoveries recommend that the T cell reaction in improving people, and doubtlessly in immunizations, are to a great extent not influenced by the transformations found in these three variations, and should offer insurance against arising variations," the NIAID said in a public statement.
