'Extreme low temperature required to store Pfizer's COVID vaccine big challenge for India'
New Delhi: The extremely low temperature of minus 70 degrees Celsius required for storing a potential COVID-19 vaccine developed by Pfizer poses a big challenge for its delivery in a developing nation like India, especially in its smaller towns and rural areas where maintaining such cold chain facilities would be very difficult, AIIMS Director Dr. Randeep Guleria said on Wednesday.
Most vaccines in India need to be stored at a temperature of two to eight degrees Celsius. The lowest minimum temperature at which vaccines can be kept to maintain the cold chain in most areas in the country is minus 25 degrees Celsius, Guleria said.
He, however, said the first set of results announced by Pfizer Inc. and BioNTech SE from the Phase 3 vaccine trial, showing a 90-per cent efficacy in preventing the coronavirus infection, is quite encouraging.
"The extremely low temperature of minus 70 degrees Celsius required for the potential anti-coronavirus vaccine developed by Pfizer poses a big challenge for its delivery in a developing nation like India.
"Storing vaccines at such a low temperature and maintaining such cold chains in smaller towns and cities is going to be very difficult," Guleria said.
He stressed that the data released by the firms developing vaccines have to be studied and it has to be seen how long the immunity would last.
About the recent surge in COVID-19 cases in Delhi, Guleria said festivities or heavily crowded marketplaces may have acted as "superspreader spots" and stressed the need to remain vigilant and follow COVID-appropriate behavior such as wearing masks, maintaining physical distancing, respiratory etiquette, and hang hygiene diligently.
Delhi recorded its sharpest single-day spike of 7,830 fresh COVID-19 cases on Tuesday, which took the national capital's infection tally to over 4.5 lakh.
Pfizer Inc. and BioNTech SE on Monday said their vaccine candidate was found to be more than 90 percent effective in preventing COVID-19.
"Today is a great day for science and humanity. The first set of results from our Phase 3 COVID-19 vaccine trial provides the initial evidence of our vaccine's ability to prevent COVID-19," Pfizer Chairman and CEO Albert Bourla said.
Asked if India was considering a tie-up with Pfizer for its COVID-19 vaccine and whether the country has the infrastructure for the specialized cold chain requirement for this vaccine, the health ministry on Tuesday said the National Expert Group on Vaccine Administration for COVID-19 is in talks with all the vaccine manufacturers, including domestic and foreign ones.

Ready to face no-confidence motion, says Karnataka CM Siddaramaiah
Hassan (Karnataka) (PTI): Karnataka Chief Minister Siddaramaiah on Saturday said that the Congress government led by him was ready to face the no-confidence motion if moved by the opposition during the legislature session from December 8.
With Deputy CM D K Shivakumar by his side, he reiterated that they would both abide by the high command's decision on the leadership issue.
"Let them (opposition) bring in a no-confidence motion or adjournment motion or any other motion. We are ready to face it. Ours is an open book, transparent government. We are ready to face anything," Siddaramaiah said in response to a question.
However, BJP state President B Y Vijayendra and Leader of Opposition in the Legislative Assembly R Ashoka, clarified that the party, along with the JD(S) has not discussed or decided anything so far regarding moving a no-confidence motion against the government.

The winter session of the Karnataka legislature will begin in Belagavi, bordering Maharashtra, on December 8 and will go on till 19th of this month.
Not wanting to react to a question on the leadership issue, the CM said the Congress high command is very strong.
"D K Shivakumar and I will be committed to whatever the high command decides," he said.
Earlier in the day in Bengaluru, Shivakumar accompanied AICC Mallikarjun Kharge till airport from Vidhana Soudha, after paying tributes to B R Ambedkar on his 69th death anniversary, which had led to some speculation about possible discussion between the two on the leadership issue.
The power tussle within the ruling party had intensified amid speculation about a change in chief minister in the state, after the Congress government reached the halfway mark of its five-year term on November 20.
However, both the CM and Deputy CM had recently held breakfast meetings at each others residences, on the instructions of the high command, which is seen as a move to pause the leadership tussle between the two and to signal Siddaramaiah's continuation as the CM for the time being, especially ahead of the Belagavi legislature session.
