Important study Omigron finds high vaccine resistance, causing mild disease in South Africa

Omigron’s first major real-world study Govit-19 The variant seemed to cause less severe disease In South Africa, It was first discovered last month, but two doses of the Pfizer-Bioendech vaccine Provides reduced protection against it.

The analysis, released by the country’s largest health care administrator on Tuesday, found the average Less than 29 percent of people are hospitalized In the region more than ever before with delta variation. However, the study also found that the two Pfizer jobs provided 70 percent protection against hospitalization from the new variant, compared to the 90 percent found in the delta wave.

Experts say it is too early to tell whether these findings are good or bad news for the rest of the world.

This may be due to the low hospital rate in South Africa Omigron is mild, Experts say, or may be the result of other factors, such as the country’s young population, many of whom are already infected, so some may have acquired natural immunity.

Ryan Noch, CEO of Discovery Health, said in a statement:

The findings in any case appear to back up data on the reduced efficacy of two doses from vaccine makers, and Omigron also appears to support early indications. Easily passable than past variants.

It was this fear that led the United States and other countries Imposes travel restrictions on South Africa and its neighbors This variation was first discovered in the region last month.

Although Omigron is mild, there is a concern among officials and experts In the United Kingdom, this variation is now close to dominance, That case numbers can be huge, and even the less severe version of the virus puts health care systems at risk.

Most early studies suggest that Omigran may be better at avoiding vaccines because it is more contagious than previous variants and has a higher number of mutations in its spike protein.

According to studies by the UK Health Security Agency and others, boosters may provide greater protection against omigran.

Vaccines have significantly reduced protection against new variant infections, the UKHSA said, with the Pfizer-BioNtech booster boosting that efficiency by 70 to 75 percent.

BioNTech and Pfizer claimed three shots of its vaccine Was able to neutralize Omigran In a laboratory test.

Danny Altman, a professor of immunology at Imperial College London, said that although Omigran was administered «imperfectly» by vaccines and boosters, «it still leaves a serious impression».

«Even if the exchange is significantly improved, hospital admissions for serious illness will be reduced by only 29 per cent, which promises even greater pressure on future health capacity,» he said.

The South African study, released on Tuesday, was led by Discovery Health in association with SAMRC, South Africa’s Medical Research Council. Saw 211,000 positive cases from November 15 to December 7, of which 78,000 are believed to be omigran.

«We are very excited about the results,» said SAMRC President Clenda Gray in a statement.

The study found that two doses provided just 33 percent protection against Pfizer-Bioentech infections compared to those not vaccinated in South Africa. This is less than the 80 percent protection provided by the vaccine against delta infection in the country.

Studies show that this protection is available to people 18-79 years of age, as well as to a variety of chronic diseases, but there is a slight decline among the elderly.

South Africa has so far used both Pfizer-BioNTech and the Johnson & Johnson vaccine. But according to Oxford University data, only 26 percent of the population has been fully vaccinated, with local health officials and experts saying vaccination reluctance is often the cause.

The researchers stressed that the findings of the study were preliminary and had not been reviewed. Data were collected from the first three weeks of the country’s omigron-driven wave and may change over time.
