Sputnik V offers higher protection than Pfizer against Omicron, claims study, Health News, ET HealthWorld

Moscow: A comparative study conducted at the National Institute for Infectious Diseases Lazzaro Spallanzani (Italy) by a joint team of researchers from the Italian Institute and the Gamaleya Center showed that two doses of Sputnik V provide more than two times higher geometric mean titers (GMT) of virus neutralizing antibodies than two doses of Pfizer vaccine against the Omicron variant. The antibodies induced in response to Sputnik V were 2.1 times higher in total and 2.6 times higher 3 months after vaccination in comparison to those induced by Pfizer.

The study was conducted on comparable sera samples from individuals vaccinated with Sputnik V and Pfizer with a similar level of IgG antibodies and virus neutralizing activity (VNA) against Wuhan variant.

The research conducted by a team of 12 Italian and nine Russian scientists led by Francesco Vaia, Director of the Spallanzani Institute and Alexander Gintsburg, Director of the Gamaleya Center has been published in medRxiv.

The study also showed that among the top quartile of individuals with high RBD-specific IgG antibodies, 100 percent of those vaccinated with Sputnik V were able to neutralize the Omicron variant in comparison to 83.3percent of individuals vaccinated with Pfizer. Among all samples, 74.2 percent

India may need to rework ‘test, trace, isolate and treat’ strategy, Health News, ET HealthWorld

The number of Covid-19 infections has been reducing in Delhi and other parts of India, but experts believe that the reason behind this decrease is not the Omicron situation improving, but low testing.

Except the elderly and patients with comorbidities, asymptomatic contacts of infected individuals are not being tested, according to the latest advisory by the Indian Council of Medical Research (ICMR). Hospitals have also relaxed testing rules of asymptomatic patients undergoing surgical procedures.

However, this may not have any impact on the containment of the pandemic.

“A majority of Covid-19 cases being reported currently are caused by the Omicron variant. It is highly transmissible and has already spread in the community. We cannot depend on the test, trace, isolate and treat strategy anymore. It is more prudent to test individuals who have symptoms and provide timely medical attention to those who develop severe infection,” Dr NK Mehra, eminent immunologist and former dean of All India Institute of Medical Sciences, told TOI.

‘Test, trace, isolate and treat’ have been the core management strategies since the beginning of the pandemic.

Dr Chandrakant Lahariya, epidemiologist and public policy expert, tells TOI that excess testing was unwarranted.

Testing can be beneficial if early
