Terming B. There are about 15 lineage defining mutations on the B1 background DG in the Indian variant. Of these, 13 are most common in global sequences.
They are seen as immune escape mutations because they help the virus evade immunity response. WHO says that currently approved COVID vaccines are expected to provide at least some protection against new variants because these vaccines elicit a broad immune response involving a range of antibodies and cells.
Early data has shown both vaccines in use in India are effective. Vaccines are also being assessed for variants including for the B. Meanwhile, even with vaccine, Covid appropriate behavior and masking remain important as they are critical to stopping virus transmission. Nifty 18, Market Watch. ET NOW. Brand Solutions.

Of the 17 identified, the most notable is the NY mutation which has been found to help the virus form a tighter attachment to the ACE2 receptors. Just as the B. This variant is known as B.
The latter has been identified in 48 countries and 30 states including Washington. In vitro studies have suggested a potential for a blunted immune response, and a small impact on vaccine efficacy. A variant that originated in Brazil was first reported in Japan, as it was identified on four people screened upon arrival at an airport outside of Tokyo.
It is postulated that the travelers acquired the variant known as P. This variant has 17 unique mutations in the spike protein that include the NY, EK and KN previously discussed. It has been identified in at least 25 countries and 22 states, including Washington. Of particular concern is the anecdotal reports of reinfection in people who had recovered from disease. Several other variants have been identified in the U. One of these variants with the LR mutation was identified in California and is considered a variant of concern.
The variant designated as CAL. It is believed to cause a stronger attachment that may prevent neutralizing antibodies from interfering with the attachment process. Additional work is needed in determining the impact this has in transmissibility, and disease severity. The B. These, in addition to the P. The predominant variant has several mutations, including the QH and has been identified in several states in the upper Midwest.
Subsequently, a second variant with the S NY mutation, which is a marker of the B. This mutation has also been associated with the South African variant. It will be important to further determine what impact these variants will have in the overall pandemic pattern. It is important to remember that what most of these variants have in common is a more effective transmission pattern, which has been associated with a surge in infections in various areas of the world.
In addition, some data suggest that increased morbidity and perhaps mortality can be associated with some of the variants. The impact on treatment and vaccines is still being determined, although preliminary data points to minimal impact on vaccine efficacy.
Moreover, vaccine manufacturers have significant capabilities in the reformulation of vaccines. We also know the transmission mode is the same as with the wild-type unchanged coronavirus, thus preventing infection should follow a similar public health guidance: facial coverings, social distancing, avoiding gatherings, and practicing appropriate hygiene and sanitation.
These simple rules along with increased immunization and appropriate levels of testing continue to be the key pillars in our management of the pandemic. Health Topics. Topics associated with the health district's mission. Frequently Asked Questions.
