A lot of people are only just able to get their first shot, so it'll take 6 weeks to get them fully protected if everyone were able to do it today. Seems wise to hold flights for 6 weeks ?
US should shut down the flights from India. We all know spreading the virus is bad for the whole world. If you blamed Chinese ran out of China, you should blame Indians for the same reason. Meanwhile, containing the virus into one single region can better utilize the worlds resource to focus. It is not time for the US to show the hospitality. Shut it down .
It does not make vaccine ineffective. At least based on current knowledge. But if the virus stays longer in non-vaccinated people the chances of a mutation that renders vaccine ineffective increases.

Shut all flights from india down until whatever is killing thousands per day is under control.
Unvaccinated people are holding back all of society.
