  • BA.2.75 not severe, won’t bring 4th wave in India, says NK Arora

    Express News Service

    NEW DELHI: Omicron sub-variant, BA.2.75, which is driving the latest Covid-19 surge in India, is not severe or brought serious diseases and risk of death despite being more transmissible than BA.2 responsible for the second Covid wave in India.

    Speaking to TNIE, Dr N K Arora, co-chair of the Indian SARS-CoV-2 Genomics Consortium (INSACOG), said the cases are not being reported from any cluster or any one particular area, despite the transmission and efficiency of the virus being 20-30 per cent more as compared to BA.2.

    “The new sub-variant has not led to any major increase or expansion of the case pool or risk of severe disease. These cases are all spread out. I would be worried if they were occurring in one or two districts. It is happening in a scattered manner. This means it is not something which is either spreading too fast or causing too many severe cases,” said Arora, head of the Covid-19 Working Group of the National Technical Advisory Group on Immunisation (NTAGI).

    An Israeli researcher first flagged the new sub-variant, and then the World Health Organisation (WHO) also said they were following BA.2.75 detected in India and other countries.

    So far, around 70 BA.2.75 infections have been reported in the country from different states, including Maharashtra, Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, and Telangana and Uttar Pradesh.

    When asked whether the surge in Covid cases in the country due to the new sub-variant could lead to a fourth wave, Arora said India is not entering the fourth phase of the pandemic.

    “We are very much part of the third wave led by Omicron because any new wave has to be with a new variant of concern. What we are seeing are all off-springs of Omicron. There should not be any concern about this new sub-lineage,” he added.

    “What is important is whether any of these new sub-lineages cause severe or serious diseases, which requires hospitalisation or requires ventilation or which is likely to lead to death,” he said, adding that deaths are being reported from those individuals who were already admitted for some other diseases, like cancer, heart, lung, liver and then they got infected with Covid.

    India has been seeing a continuous Covid-19 surge since June.

    Arora said that the reason is mainly that people have become complacent, attending substantial social gatherings, travelling, and also due to the increased transmission ability of the sub-variants.

    “We are keeping a close watch through genomic and sewage surveillance to see if there is anything new which is of public health concern or could cause severe disease to an individual,” he added.

  • Covaxin booster dose enhances vaccine effectiveness against Delta, Omicron variants, says ICMR study

    By PTI

    NEW DELHI: The administration of Covaxin as a booster dose enhances vaccine effectiveness against COVID-19’s Delta variant and gives protection against Omicron variants BA.

    1.1 and BA.2, a study by ICMR and Bharat Biotech has found. The protective efficacy of Bharat Biotech’s Covaxin following two and three-dose immuniszations against the Delta variant and the efficacy of the Covaxin against Omicron variants were studied in a Syrian hamster model (animal model to study human-associated diseases), it said.

    The antibody response, clinical observations, viral load reduction and lung disease severity after virus challenge were observed, it added.

    The findings of the study have been published on Tuesday on bioRxiv, a pre-print server and have not been peer reviewed.

    “In the Delta infection study, where we compared the protective response between the two and three-dose regimens, we could observe the advantage of the booster dose vaccination in the protection.

    Although the neutralising antibody levels were comparable among the groups, lung disease severity was found more reduced after the three dose vaccination.

    “The virus shedding and viral organ load were considerably reduced in both the two dose and three-dose immunised animals indicating the vaccine efficacy against Delta variant,” the study by Indian Council of Medical Research and Bharat Biotech said.

    In the second study in which the protective response was assessed against Omicron variants i.e. BA.1 and BA.2, following three-dose vaccinations, lesser virus shedding, lung viral load and lung disease severity were observed in the immunised groups in comparison to the placebo groups.

    “The evidence from the present study shows that Covaxin booster immunisation tends to broaden the protective immune response and reduces disease severity against the Delta and Omicron variant infection,” it further said.

  • COVID surge not harbinger of ‘new wave’ but ‘expected fluctuation’: Experts

    By PTI

    NEW DELHI: The current rise in COVID-19 cases is not a harbinger of a “new wave” but an “expected fluctuation” during endemic prevalence, experts have said, emphasising that lack of mask-wearing and low intake of booster shots may be reasons behind the surge.

    They also said the recent surge is due to increased travel, social gathering and economic activities resulting in a greater possibility of the transmission of the virus.

    Seventeen districts in India, including seven from Kerala and five from Mizoram, are reporting a weekly COVID-19 positivity rate of more than 10 percent.

    In 24 districts, including seven from Kerala and four each from Maharashtra and Mizoram, the weekly positivity is between 5 to 10 per cent, an official source said.

    Noted virologist T Jacob John said the present increase in cases is not like a surge but a gradual increase that is not steady or uniformly distributed.

    “A few states lead, others are not involved. In those states, the phenomenon is mainly a big city picture, not widely spreading. This pattern is not a harbinger of a new wave but expected fluctuations during endemic prevalence,” he said.

    “A wave must have more numbers than the previous day consistently — that is not the case for us now,” he told PTI.

    He said not wearing and not taking booster shots can be two main reasons for the surge.

    “Who gave the orders that people need not wear masks any longer. Who advised that people should continue wearing masks in places where people assemble indoors? That one behaviour alone is sufficient to explain the gradual increase in cities,” John said.

    The second obstacle, he said, is people not taking booster doses.

    “The higher the booster dose coverage, the lower will the number of infections; lower the number of infections, lower the number of cases,” he said.

    John, a former director of the ICMR’s Centre of Advanced Research in Virology, said less than five per cent of those who had a second dose had taken their boosters.

    “Who is responsible for this low coverage? I understand people are not trusting the government regarding vaccine safety — and the government is not bothered either.”

    ”When the threat of epidemic is no longer urging people to opt for a complete immunisation schedule, people will not accept the risk of severe adverse reactions,” he said.

    He refuted claims that new variants are responsible for the surge.

    “Currently the popular feeling is that BA.5 and BA.4 are causing the increase. On the other hand, when viruses are encouraged to spread, the faster-spreading ones will show up,” he said.

    Dr Chandrakant Lahariya, physician-epidemiologist and infectious disease specialist, said India’s situation is of hybrid immunity through natural infection (three national waves) and acquired immunity as nearly 88 per cent of the adult population has received two shots of COVID-19 vaccines.

    “Then, Omicron is the predominant variant and even though two new sub-lineage of Omicron, BA.4 and BA.5 have been reported to be slightly more transmissible, those sub-lineage are barely present in India and not enough to fuel a major spike.”

    “There is no evidence of the emergence of a new variant of concern. Putting all of these together, it is fair to conclude that the current localised surge is not a start of a new national wave,” he said.

    To put the surge in context, he said there are two things to remember.

    “One, neither an earlier SARS CoV2 infection nor the COVID-19 vaccination (at least not the ones which are being used in India) are known to prevent subsequent infection.”

    “Second, now SARS CoV2 is present in all settings and is likely to stay around for long. Alongside, COVID-19 being an infectious disease, the rise and fall in the cases is going to be a routine process. What we are seeing in select Indian cities and states in terms of a spike in COVID-19 cases is on expected lines,” he told PTI.

    A rise may be seen in additional cities and states in months to follow but with every rise “we should not jump to the conclusion that it is a fresh wave”, he said.

    Giridhar R. Babu, who also heads Lifecourse Epidemiology at the Indian Institute of Public Health in Bengaluru, said there is a need to stop numbering waves, especially when the UK has seen three waves within six months.

    “Waves result from myriad factors, including testing levels, case definition, etc. Instead, each outbreak should be promptly identified and controlled.”

    “Given an uptick in new deaths attributed to COVID-19 observed in a few countries (in European Union, the US, Portugal, Taiwan, New Zealand, and England.), it is important to continually track data from epidemiological assessment and correlate with genomic sequencing,” he said.

    He said the plausible reason behind the surge in cases is mostly due to the newer sub-lineages, as seen in the rest of the world.

    “After a prolonged period of Delta dominance and subsequent omicron variant, BA.2 is overtaken by a combination of several sub-lineages (BA.4, BA.5, BA.2.12.1, etc.), it is very unlikely that this is not the same reason in India as well,” he said.

    The proportion of persons covered with booster doses, especially among the vulnerable, and appropriate ventilation to ease crowds in congested spaces are key determinants of overall control of the wave, he stressed.
