It's not about efficacy of the Covaxin, it's a bargaining chip to withhold their WHO approval till Pfizer/J&J get what they want.Your have a valid point but
Look at above aggrement BB have get into.
Moreover, BB have applied for WHO emergency use authorisation some time back. Remember reading the tweet. In another month or two, they will be on WHO list.
Off all the vaccines, they are the best with max protection partly because they r using dead virus instead of MRNA. Traditionally, vaccines r from dead virus only so they r proven and effective.
Point is that even if countries choose to enforce vaccine passport... We have nothing to worry... I travel a lot to Europe / US and deliberately took BB vaccine. So don't worry... Airline / toursim industry too will push WHO to include all vaccine in their list. It's all about dollars...
With Pfizer / moderna coming to India shortly, I think deal is stuck already and its a matter of time only...
Now that Pfizer are being allowed to sell in India, likely Covaxin will get WHO approval soon. That was my whole point.
It's not about the money, it's whether it would be safe to mix different kinds of vaccines - mRNA, vector, inactivated virus etc.My reading is that it wouldn't be like exactly like you have said.
Countries that will introduce this rule will ask everyone without a WHO certified vaccine certificate to take a jab of single dose vaccine at the port of entry.
The price of vaccine and administering of it to be borne by the traveller themselves.
So if a single vaccine costs $50 and service charge $25 then you will have to pay $75 at the time of entry.
PS: I am a frequent traveler myself (in fact I returned in the nick of time last year) and I took Covaxin as well. Simply, because I value my life over the ability to travel to the west.
