Covid-19 Vaccine: Omicron infection better at boosting immunity than booster dose

New Delhi: Coronavirus is infecting people all over the world. The latest trends in India show that the hospitalization rate is very low and the recovery is fast. A new study now shows that Omicron infections produced a better immune response than a booster shot in vaccinated people.
A pair of studies indicate that people who are vaccinated and then infected with Omicron variants may have better antibodies to combat a wider range of COVID-19 variants. The study by vaccine maker BioNTech SE and the University of Washington reassures the world, even as cases continue to rise in many parts.
The study has been published in preprint on the BioRxiv server. However, the study authors caution and caution people not to seek infection in response to the findings.
John Vary, a professor and director of the Institute for Immunology at the University of Pennsylvania, who reviewed the study, told Bloomberg that a breakthrough infection should be considered essentially equivalent to another dose of the vaccine, and that if someone had recently had covid, So they can wait before getting another booster shot.
Researchers have argued that offering people an Omicron-optimized booster shot may be more beneficial than many people with the original vaccines. David Wesler, an assistant professor at the University of Washington, told Bloomberg, "We're at the point where we can consider having a different vaccine to boost people."
The researchers also identified antibodies in the nasal mucosa of these patients, which may help neutralize the virus once it enters the body.
Meanwhile, the study also found that the response was missing in unvaccinated people who had caught Omicron as their first exposure to the virus and warned that if a new variant is significantly different, remaining unvaccinated could be dangerous.
The new research comes against the backdrop of a surge in cases in countries such as China and North Korea. About one million people are in strict lockdown in Shanghai. Officials have said that most of Shanghai has stopped the spread of coronavirus in the community. China reported 1,159 cases of Covid-19 infection on Monday. The highest number of coronavirus cases was in Shanghai. Almost all were infections without symptoms.
India recorded 2,202 new cases of Kovid-19 in the last 24 hours, which is 11.5% less than yesterday. Delhi has 613 cases, followed by Kerala with 428 cases, Haryana with 302 cases, Maharashtra with 255 cases and Uttar Pradesh with 153 cases among the top five states reporting the highest number of cases.
