India in talks with Pfizer, says AIIMS director..
Dr Randeep Guleria, director of All India Institute of Medical Sciences (AIIMS) Delh, today said that India is in talks with Pfizer-BioNTech Covid-19 vaccine.
He said, “We have two challenges in front of us now. One to break the transmission chain, two to make the vaccine available to all.”
For India, RNA vaccines are going to be very expensive…
The coronavirus vaccine by Pfizer, which is based on a novel technology that uses synthetic mRNA to activate the immune system against the virus, needs to be kept at minus 70 degrees Celsius (-94 F) or below…
It would be a challenge to distribute Pfizer’s coronavirus vaccine in rural areas of India or poor countries where resources are tight.
A logistical obstacle..
This will be a challenge in all settings because hospitals even in big cities do not have storage facilities for a vaccine at that ultra-low temperature. In fact, one of the most prestigious US hospitals, the Mayo Clinic in Rochester said it does not currently have that capability.
Dr. Gregory Poland from Mayo Clinic said that..
We’re a major medical center and we don’t have storage capacity like this. That will be true for everybody. This is a logistical obstacle.
