Is Omicron Variant Infective?

Published On Feb 24, 2022

According to new research, the most recent version of the extremely contagious omicron variant is spreading much quicker than the original, and moderate instances of the original may not provide any immunity against future infections. The findings put doubt on expectations that the omicron wave currently sweeping the globe may speed the pandemic's conclusion. As people weary of pandemic limitations, vaccinations become more affordable, and mortality stay low, demands that authorities to classify Covid-19 as an endemic resembling influenza are growing across the world.
According to one study from scientists at the University of California, San Francisco, the generation of neutralising antibodies during an omicron infection appears to be connected to the severity of the sickness before it is peer-reviewed. According to the researchers, the mild version of most omicron infections in vaccinated persons may render those who recover still exposed to present virus and future varieties that evolve. To know more if the Omicron variant is more infectious or not, read on.

Omicron Variant - Studies

The study discovered that natural infection protection was around one-third of that achieved with a booster injection. "Our findings imply that, should another, more dangerous variation develop in the future, omicron-induced resistance may not be adequate to prevent infection." "According to the researchers. "They also stress the significance of vaccination boosters in boosting immunity, as emerging illness alone may not be sufficient." "They claimed that this would help prevent future infections or sickness from new strains.
In the second investigation, researchers discovered that a second-generation strain of omicron is considerably more transmissible than the original. It revealed that 39 percent of persons had been infected with the BA. Those who had the subvariant 2 were more likely to infect individuals in their families, compared to 29% of those who had the original version. The researchers looked at data from 8,541 families in Denmark in December and January to see if the new subvariant became the dominant strain. The likelihood of contamination with either kind was greater in individuals who had not been vaccinated, indicating that vaccination had a favourable effect, according to the researchers. The findings back with research revealed last week by UK health officials, which indicated that the omicron subvariant is even more infectious than that of the initial fast-spreading strain. Booster injections, according to the United Kingdom's Health Security Agency, are still an effective protection.
While BA.1 remains the most common form worldwide, recent trends show BA.2 is becoming more prevalent in several countries, including India, South Africa, the United Kingdom, and Denmark, according to the World Health Organisation. Until new findings are publicly published, both studies are subjected to a comprehensive assessment by other specialists. Scientists from the University of Copenhagen, Statistics Denmark, Technical University of Denmark, and Statens Serum Institut conducted the Danish study. Charles Chiu of the University of California, San Francisco, was in charge of the other.
According to Scott Gottlieb, former director of the US Food and Drug Administration, the omicron subvariant looks to be more infectious, but there is no evidence that it is more hazardous or immune to vaccinations.


While Omicron has had a significant impact on our whole community, including a massive increase in hospitalizations and fatalities, as well as a massive number of hospitalised children, the new variety appears to produce less severe illness in certain infected people and animal models. Those that are unvaccinated or have certain risk factors, on the other hand, are still at a high risk of severe symptoms and death. In the following months, other mechanisms driving the variant's odd behaviour are anticipated to be discovered. Future versions, when they exist, might have even more changes. With infections spreading and evolving across various communities throughout the world, the virus will find new methods to spread—including ones that scientists haven't yet considered.
