Unfortunately, Nebraska is behind compared to other states, with only about 16% of those who are eligible to have received a booster actually getting the shot as of January 2023. By Katherine J. Wu. These boosters are designed to protect against disease caused by the original strain of the SARS-CoV-2 virus, as well as the Omicron subvariants BA.4 and BA.5 (although experts are still learning about their effectiveness against the latest Omicron subvariants). On Sept. 2, the Centers for Disease Control and Prevention expanded the updated bivalent booster vaccine for children ages 5 and older. Some changes and mutations allow the virus to spread more easily or make it resistant to treatments or vaccines. At the same time, however, we are always looking ahead and preparing for the continuation of the campaign. These updated boosters are bivalent, meaning they offer protection against the latest omicron variants plus the original COVID-19 strain. A major reason is Omicron has accumulated over 50 mutations, including about 30 in the spike protein, the part of the coronavirus that mRNA vaccines teach our immune systems to attack. Stuart Ray, M.D., vice chair of medicine for data integrity and analytics, and Robert Bollinger, M.D., M.P.H., Raj and Kamla Gupta Professor of Infectious Diseases, are experts in SARS-CoV-2, and they address your questions about the omicron coronavirus variant. Led by Professor Song Dae-sub of Seoul National Universitys College of Veterinary Medicine and researcher Yoo Kwang-soo of Jeonbuk National University, the study is the first of its kind to find transmission among dogs. These updated bivalent boosters offer protection against the omicron variants, plus the original COVID-19 strain. Yes, the latest Omicron variant of the novel coronavirus is bad. When a variant is eventually dubbed omega, what will its successor be named? Currently, the Centers for Disease Control and Prevention (CDC) has identified one variant of the virus (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) as a variant of concern: In April, the CDC downgraded the delta variant from a variant of concern to a variant being monitored. Many of these variants mutations have little or no impact on how the virus affects humans. All lineages currently circulating are classified as part of the Omicron variant. But the WHO said there was no indication so far that it was more serious or harmful than previous Omicron variants. COVID vaccine makers brace for a variant worse than Delta. A century later, there remains considerable frustration in some circles given that the Spanish flu likely started in Kansas.

The wildcard variant has already been detected in several Australian states and more than 30 countries and has scientists . Although new variants are an expected part of the evolution of viruses, monitoring each one that surfaces is essential in ensuring wein the U.S. and globallyare prepared. In the study, Beagle dogs were infected with the Delta and Omicron variants of the virus through their noses. She said these evolutionary changes were like "stepping stones", as the virus evolves to find new ways of bypassing the body's defence mechanisms.
