Can you keep up with the evolving COVID-19 subvariants?

The new Omicron variants BA.4 and BA.5 are gaining momentum at an accelerating pace against other COVID-19 strains.

News promotion: Report from early June These two strains have been shown to account for only 6% and 7% of all cases in the United States. After four weeks, the new variants account for more than half of all new infectious diseases in the country.

But new research raises more concerns: Findings published in the New England Journal of Medicine reveal that each Omicron mutation is likely to cause reinfection or breakthrough infection. ABC News..

What they are saying: “It’s essentially an arms race.” Said Dr. Danbaruch, author of a recent study and director of the Virology and Vaccine Research Center at the Beth Israel Deaconess Medical Center in Boston. “As the population becomes more immune, the virus becomes more and more antigenic.”

  • He added that current vaccines still reduce the severity of the disease. This is “the most important goal of vaccination”.

Play status: It is no exaggeration to say that these rapidly evolving mutants complicate vaccine renewal. Consider the “stealth” Omicron or BA.2.12.1 strain, which currently accounts for over 40% of cases, or BA.2, which accounts for more than 5% of cases. On the other hand, the BA.1 strain does not explain anything.

What should the jab target, keeping in mind the next vaccine to be rolled out later this year? Should it undertake the current Omicron strain or prepare for other mutations?

  • Penny Moore, a virologist at the University of the Witwatersland in Johannesburg, South Africa, said: Nature.. “We have a solid track record of making mistakes.”

Symptoms In the case of Omicron, it can appear 2 to 14 days after exposure.
