Highlight
A facelift of COVID BA.4.6. It is spreading rapidly all over the world.
This variant spreads faster than other variants of Omicron.
The only way to prevent this is through vaccination with a “booster dose”.
London: BA.4.6Omicron’s new form of COVID, is spreading rapidly in the US. It has now been confirmed that it has also been filed in the UK. The UK Health Safety Agency’s (UKSHA) new briefing document on COVID variants mentions that in the week starting 14 August, BA.4.6 Variants It accounts for 3.3% of cases in the UK. But recent research has shown that 9% of COVID-19 cases in the UK are BA.4.6. Why is it contributing? Similarly, BA.4.6 now accounts for more than 9% of recent cases across the United States, according to the Centers for Disease Control and Prevention. This version has also been recognized in many other countries of the world. So should we worry about the BA.4.6 variant? Let us now have a look at the information-
BA.4.6 This is the BA.4 variant of Omicron. BA.4 Why the first time in January 2022? South Africa and since then it has spread around the world with the BA.5 version. It is not entirely clear how BA.4.6 emerged, but it is possible that it may be a recombinant variant. Recombination occurs when two different strains of SARS-CoV-2 (the virus that causes COVID-19) infect the same person at the same time.
While BA.4.6 is similar to BA.4 in many ways, it mutates the spike protein, a protein on the surface of the virus that allows it to enter our cells. This mutation, R346T, has been seen in other variants and protects the virus from the individual’s immune system. In other words, it helps the virus evade the antibodies obtained from vaccination and prior infection.
Severity, infectivity and immune evasion
Fortunately Omicron wasn’t very destructive, but the Omicron sub-types spread very quickly. BA.4.6 Activates the body’s immune system. According to a UKHSA report, BA.4.6 spreads much faster than BA.5 in its early stages. At the same time, according to a report by Oxford University, people who have taken Pfizer supplements to protect themselves from Kovid, their antibodies have no effect on BA.4.6. Which is a topic of discussion. However, a booster dose may be successful enough to avoid BA.4.6. Since there is no complete information about this new version, we can rely only on the booster dose for now.
criticism is important
The emergence of BA.4.6 and other new variants is a matter of concern. Their new look suggests that the virus is still with us, and is trying to enter our bodies in a new way, bypassing the immunity gained from vaccination.
but criticism Provides good protection against serious illness. It is still the best weapon to fight against COVID. bivalent booster That recent approval is good news for us. In addition, developing multivalent coronavirus vaccines that target multiple variants could provide more durable protection.
A study by Hull showed that nasal medium A multicomponent coronavirus vaccine called SE has been shown to be more effective against the original form of COVID and two other forms of it. The new variants, including BA.4.6, are being closely monitored as they could lead to the next wave of the COVID pandemic. To the public… Be vigilant and follow any public COVID rules to prevent the spread of this highly contagious virus.
