HOW DO WE KNOW IF VACCINES WORK AGAINST OMIGRAN?

Studies are underway to examine how vaccines work against the new variant, with some experts expressing initial hope that they will provide protection. Although this variant restricts the effectiveness of vaccines, experts say it does not completely block the protection provided by vaccines. "I expect that mutations in this variant are not going to eliminate or eliminate that kind of antibody neutralization from vaccines or previous infections," Bloom said.

"Regardless of whether this new variant spreads, I recommend that people do their best to reduce their chances of contracting SARS-CoV-2," Bloom added, referring to the virus by its technical name. "There are some obvious things you can do: get vaccinated, get booster vaccinated, wear a mask." Despite the small size of the sample, Ian Sunny, an epidemiologist and a member of South Africa's ministerial advisory committee on Covit-19, said doctors had seen an increase in the rate of progressive infections among those previously vaccinated in South Africa. Preliminary data indicate that vaccines are still effective, with most hospitals having people who have not been vaccinated.

Among other types, including delta, vaccines and, in particular, boosters provide a measure of protection against particularly serious diseases, Fossie said Tuesday. "So, as we're talking about boosters, there is every reason to believe that when you get high enough, you'll get at least some cross-protection against particularly serious diseases," he said. On Monday evening, Biden tweeted that the federal government would "accelerate" the development of anti-omicron vaccines, if necessary.

Meanwhile, vaccine makers, including Pfizer and BioNTech, Moderna, and Johnson & Johnson, said they were working to understand how well their vaccines could counteract omicron. Modern CEO Stephen Bancel said on Tuesday that he believes existing corona vaccines will be far less effective against Omicron. He said in a previous press release that the company was "moving as fast as possible to implement our strategy to address this variance". In addition, Pfizer and BioNTech "expect to be able to develop and produce a vaccine designed against that variant within about 100 days," regulatory approval is pending, a Pfizer spokeswoman said in a statement. Considering the spread of Omicron in South Africa, many experts have pointed to the need for fewer countries to be vaccinated to increase world security in the future.

“I think vaccine equity is a very important issue,” Bald told the University of Edinburgh, indicating that low vaccination rates in many African countries and the high prevalence of the virus are subject to multiple genetic mutations each time. It jumps between individuals. However, as seen with the delta variant, the spread of the coronavirus will not be eliminated even by vaccination, and mutations will eventually "occur in any country," Bald said.

Will Omigran cause serious illness and will existing therapies work?

Since there are still a small number of cases, it is difficult to know. One doctor in South Africa said early patients had mild symptoms, while another warned that they saw younger people with mild and severe illnesses. "Making a common decision can be wrong at this point," Alex Siegel, a faculty member at the Africa Health Research Institute, told The Post. "But we can say it's not much different than anything we've seen before." He added: "There is no indication that this is going to do anything completely different."
