The source of avian influenza or H5N1 is mainly poultry animals. "Anyone in close contact with these animals is infected, but human-to-human infections have never been observed," Dr Guleria said.
"Currently the vaccines that we have in India are covering for what was originally the Wuhan strain. After that we had so many variants. And therefore if we have to have a new vaccine, it should provide cover for the circulating strains like we do for influenza," he said.
New variants will keep coming as the virus keeps on mutating over the time and the XBB 1.16 is sort of a "new kid on the block", Guleria said.
According to an official document released by AIIMS hospital on Thursday, Dr. Randeep Guleria's term as director of AIIMS New Delhi has been extended by an additional three months.
Dr Randeep Guleria remarks have come in the wake of concerns over the new Omicron variant of COVID-19.
The Delhi oxygen audit is an interim report, and a final report is awaited, Dr Randeep Guleria said, adding that the matter is currently in the Supreme Court.
AIIMS Chief Randeep Guleria further said that the Covaxin "covers a wide spectrum" as Bharat Biotech is conducting trials between the age group of 2 to 18 years.
The arrival of the third wave could be expedited through the violation of COVID-appropriate behaviour, Dr Randeep Guleria said.
The need to boost vaccine production, as stated by AIIMS chief Dr Randeep Guleria, comes in the backdrop of several states reporting a shortage in vaccine supply that has hindered their respective inoculation programmes.
Good control and regular monitoring of blood sugar levels of those on steroids is also important, Dr Guleria has said.
Recent studies conducted by the US Centre for Disease Control and Prevention (CDC) found that double masking could minimise the risk of virus exposure by up to 95.9 percent.
AIIMS Director Dr Randeep Guleria also warned that if the situation is not reversed, then the galloping infection rate will eventually cause a huge strain on the country's healthcare system. He sought stricter enforcement of COVID-appropriate behaviour on the ground level by the administration and authorities.
The mutated version of coronavirus could 'escape' through the immune system developed by the body. In such a scenario, maintaining COVID-19-approporiate behaviour is of utmost necessity to reduce the pace of transmission, said Dr Randeep Guleria.
