No Scientific Data So Far To Show Delta Plus Variant Adversely Impacts Vaccine Efficacy: V K Paul

When asked about the Delta plus variant, Paul said scientific knowledge about it is still in the early stage.

Amid the rising concerns over the Delta plus variant of the virus, Paul, who is also a Niti Aayog member, proclaimed that there is no scientific data so far to establish that the new variant is highly contagious or reduces vaccine efficacy.

Covid Task Force Chief V K Paul on Monday said that, it will be unfair to put a date for any coronavirus wave as the behaviour of coronavirus is unpredictable and a disciplined and effective pandemic response can help the country get away from any significant outbreak.

Paul in an interview to PTI, said that another wave of any size would depend upon various factors, including overall discipline in terms of Covid-appropriate behaviour, testing and containment strategies, and vaccination rates.

“And in addition, the unpredictable behaviour of the virus can also change the pandemic dynamics. In such a scenario, their complex factor will determine the chain of transmission and outbreak.”

He said, “Occurrence or non-occurrence of any wave, is not in our own hands. To my mind, it is not fair to put any date for any wave.”

“If we are determined and disciplined and marshal effective pandemic response, we should be in a position to get away from any significant outbreak,” Paul said.

Three Covid vaccines are currently are being used for vaccination in India- Covaxin by Bharat Biotech, Covishield by Serum Institute of India (SII) and Russia’s Sputnik V.

When asked about the Delta plus variant, Paul said scientific knowledge about it is still in the early stage.

Daily fresh cases of Covid have come down from four lakhs during the peak of the second Covid wave to around 50,000 in the past few days and the unlock process or lifting of restrictions is underway in many parts of the country.

“The so-called Delta plus variant exhibits an additional mutation in the Delta variant and since this is a new variant, scientific knowledge is still in the early stage.

“Whether this additional mutation in the Delta variant is associated with increased transmissibility or excess severity of disease, or any adverse effect on vaccine efficacy is currently not established and we should wait for this information to emerge.

“And we should wait for these aspects to be studied systematically,” he pointed out.

A new viral variant of the coronavirus, Delta Plus, was identified on June 11, and was recently classified as a variant of concern.

On the effectiveness of Covaxin and Covishield against the Delta variant of the coronavirus, Paul said that based on the scientific studies done by the ICMR, both vaccines are effective against the coronavirus, including the Delta variant, which is presently the predominant variant in the country.

ICMR is the Indian Council of Medical Research.

When asked if India is close to giving indemnity to foreign vaccine makers like Pfizer and Moderna, Paul said the issue has multiple dimensions and it is not wise to give a timeline for such issues.

“The discussion for paving the way for internationally developed vaccines to India, is going on. The issue has multiple dimensions and we are trying to find an agreed way forward at the earliest.

“We are trying to expedite the progress in every possible way,” he said.

However, he did not delve into the indemnity issues with respect to approving the vaccines made by foreign companies.

Indemnity is one of the issues that is still to be sorted out between the authorities and the companies — Pfizer and Moderna — with respect to approving their respective vaccines for use in India.

About the progress in Bharat Biotech’s Covaxin application for getting emergency use listing (EUL) certificate from the World Health Organisation (WHO), Paul said the process is proceeding very well.

“Additional documents were submitted by the company last week. We would like to see an expedited review of the data and hope that the decision will come very soon,” he noted.
