Pasteurising breast milk may inactivate novel coronavirus, claims study

Toronto, Jul 10: Pasteurising breast milk at 62.5 degrees Celsius for 30 minutes inactivates the SARS-CoV-2 virus that causes Covid-19, making it safe for consumption by babies, a study claims.

According to the research published in the Canadian Medical Association Journal, current advice for women with Covid-19 is to continue to breastfeed their own infants.

In Canada, it is standard care to provide pasteurised breast milk to very-low-birth-weight babies in hospital until their own mother's milk supply is adequate, the researchers said.

"In the event that a woman who is Covid-19-positive donates human milk that contains SARS-CoV-2, whether by transmission through the mammary gland or by contamination through respiratory droplets, skin, breast pumps and milk containers, this method of pasteurisation renders milk safe for consumption," said Sharon Unger, a professor at the University of Toronto in Canada.

The Holder method, a technique used to pasteurise milk in all Canadian milk banks at 62.5 degrees Celsius for 30 minutes, is effective at neutralising viruses such as HIV, hepatitis and others that are known to be transmitted through human milk, the researchers said.

In the latest study, the researchers spiked human breast milk with a viral load of SARS-CoV-2 and tested samples that either sat at room temperature for 30 minutes or were warmed to 62.5 degrees Celsius for 30 minutes.

They then measured for active virus, finding that the virus in the pasteurised milk was inactivated after heating.

More than 650 human breast milk banks around the world use the Holder method to ensure a safe supply of milk for vulnerable infants, the researchers said.

In view of the winter season and COVID-19, health experts on Wednesday said that many people are taking pneumonia and influenza vaccines as a precaution to save themselves from respiratory infections.

Experts have warned that it is highly possible that people may contract both influenza and the COVID-19 infection in winter, leading to devastating consequences.

Dr Avi Kumar, Consultant - Pulmonology, Fortis Escorts Heart Institute in New Delhi said, "What we are generally following is that in post COVID patients we are giving flu vaccine as well as the pneumonia vaccine."

"Because right now we are at the start of winter and this is generally the beginning of flu season as well as coronavirus. Both are RnA viruses so the vaccine which is available against influenza is known to be very helpful in reducing hospitalization," Kumar explained.

International researchers have recently found that receiving the influenza vaccine does not increase a person's risk of contracting COVID-19 or worsen associated morbidity or mortality.

Published in the Journal of Clinical and Translational Science, the study shows the flu vaccine is the single most important intervention to help in staying healthy this fall and winter.

"More studies need to be done to confirm the same, only a few studies cannot confirm it," Kumar said.

"However, what is available with us right now is prevention of other respiratory infections in the form of flu as well as pneumonia so that hospitals are not overburdened with other respiratory illnesses as well as Covid patients," he added.

"Hence, we prefer tetravalent inactivated flu vaccine which has been given to every patient in post Covid status.

"In addition we have been giving them vaccines for pneumonia, conjugate vaccine is been given to the age group of above 65 years, this vaccine is given only once in a lifetime. We are also giving a polyvalent vaccine which is to be repeated once in every five years," Kumar said.

According to Dr Akshay Budhraja, Consultant Department of Pulmonology, Aakash Healthcare Super Speciality Hospital, in the absence of a vaccine specific to the Covid-19 virus right now, they are checking the vaccination history of the patient.

"We give one shot of flu vaccine every year and pneumococcal vaccine is given once in five years. As of now, we have not faced any shortage," Budhraja told IANS.

Geneva, Nov 24: "There is now real hope that vaccines, in combination with other tried and tested public health measures, will help to end the pandemic," said the World Health Organisation (WHO) Director-General Tedros Adhanom Ghebreyesus.

The WHO chief's remarks came after drugmaker AstraZeneca said on Monday that its COVID-19 vaccine, developed with Oxford University, was up to 90 percent effective, making it the third major drug company after Pfizer and Moderna to have reported late-stage data for a potential COVID-19 vaccine, Xinhua news agency reported on Tuesday.

"The significance of this scientific achievement cannot be overstated. No vaccines in history have been developed as rapidly as these. The scientific community has set a new standard for vaccine development," Tedros added.

He pointed out now the international community must set a new standard for access, as "the urgency with which vaccines have been developed must be matched by the same urgency to distribute them fairly."

Worried that the poorest and most vulnerable countries will be trampled in the stampede for vaccines, WHO established the Access to COVID-19 Tools Accelerator to support global efforts in developing vaccines, diagnostics and therapeutics, and has joined so far 187 countries in the COVAX facility to collaborate on the procurement and rollout of vaccines, ensuring affordable prices, volumes and timing for all countries.

According to the WHO chief, some US $4.3 billion is needed immediately to support the mass procurement and delivery of vaccines, tests and treatments, while additional US $23.8 billion will be needed next year.

"The International Monetary Fund estimates that if medical solutions can be made available faster and more widely, it could lead to a cumulative increase in global income of almost US $9 trillion by the end of 2025," he said.

Pune, Dec 1: Vaccine development company Serum Institute, India on Tuesday said the Covidshield vaccine will not be released for mass use unless it is proven immunogenic, and safe.

The company also said the serious adverse event (SAE) that happened to a city based volunteer though unfortunate was in no way induced by the vaccine.

Serum Institute which had earlier said it would claim over Rs 100 crore damage from the volunteer for damaging its reputation said it was sympathetic with the volunteer's medical condition and the incident is highly unfortunate.

"However, we would like to clarify that all the requisite regulatory and ethical processes and guidelines were followed diligently and strictly," the company said.

According to Serum Institute, the concerned authorities were informed and the Principal Investigator, Data Safety Monitoring Board (DSMB) and the Ethics Committee independently cleared and reckoned it as a non-related issue to the vaccine trial.

"Post which we submitted all the reports and data related to the incident to the DCGI (Drug Controller General of India). It is only after we cleared all the required processes that we continued with the trials," the company said.

"Taking into consideration the complexities and existing misnomers about vaccination and immunisation; the legal notice was sent therefore to safeguard the reputation of the company which is being unfairly maligned," the company added.

The 40-year-old city based volunteer, who works as a business consultant had wanted to investigate the cause of him contracting severe neurological health complications he had suffered after being vaccinated with Covidshield shots under development at Serum Institute, but the company was intimidating him with a threat of over Rs 100 crore damage suit, his advocates had said.

According to the advocates, their client was vaccinated on September 29 and developed severe neurological health complications and instead of probing the cause and stopping the trials Serum Institute and others kept silent.

"We are yet to get any reply for the legal notice sent to various parties, including Serum Institute. We have seen news reports about Serum Institute threatening our client with a suit for over Rs 100 crore," N.G.R. Prasad, Advocate, Row & Reddy, told IANS.

"Our client had restricted his claim only for Rs 5 crore and wanted investigation to start as to the cause of him suffering severe neurological problems and stop the vaccine from affecting other people," Prasad added.

A family friend of the volunteer told IANS: "He was a healthy young male. He had no pre-existing ailments. Not even blood pressure. But 10 days after the vaccination, he had developed severe neurological complications."
