I have only 1 question - about "Sputnik" - why do you have such an interest in this dubious drug? How can it be useful for India, if its production in the Russian Federation is insignificant, it is not enough even to cover its internal needs, while in India itself, the CoviShield vaccine is produced, which is certified, and it has been tested for safety?
We don't have any other choice.
I am waiting for my turn ever since the vaccination program started in India (3 months back). But for now, those who are aged below 45 has no chance of getting a slot, at least for the next 2-3 months. Covishield and Covaxin are being manufactured in India at a rate of around 1.5 million doses per day. And the government has specified that those who are above the age of 45 years will be given priority and those aged <45 are low priority for them. As per the government directive, 70% of the vaccine supply has to be used as the second dose.
A number of my relatives and friends have recently died as a result of COVID. At this point, I really don't care whether it is Sputnik or Sinovac. I just want to get vaccinated using any vaccine that is available. And the strain that has emerged in India (B.1.617) seems to be a hundred times more contagious than the original strain.
You can't risk your health like that! It is still difficult to say what could be more harmful - a mild form of Covid or the consequences of a dubious drug ...
So I will remind you once again - Sputnik V will not help you in any way, it is simply not physically available in the volumes that are needed. And you have your own full-fledged and very powerful production. Moreover, a high-quality vaccine is sufficient. Let not the best, but already proven and predictable in terms of efficiency. Moreover, today the developers of Sputnik V have not provided all the necessary data and continue to manipulate data on the drug, so the World Health Organization (WHO) does not approve of this dubious drug to be used even for emergency use ...
We have approved:
Oxford / AstraZeneca (actively used)
Pfizer / BioNTech (delivery pending, highly limited volume)
Sinovac (actively used)
Jannsen seems to be expected, but I can't say for sure.
I'm really more interested in Moderna - they write that it is effective against virus strains.
