Almost no one discovers such things "on their own", regardless of who they are.
And it is likely that her parents are not mopping floors at a McDonalds. We have all seen many "winners" at science fairs getting help from relatives to present a spectacular display.
In any event, since there are two binding sites by which the virus can infect (1), this compound likely must block both the ACE-2 binding domain and the neuropilin-1 binding domain (now determined as the second receptor) for allowing the virus to result in an infection. It seems unlikely that one compound would inactivate biding at both receptors.
And it has not been proven that the new compound "discovered" will even work on one receptor, much less both.
But it would be very clever of Chebrolu if she has found a blocking agent that prevents infectivity for at least one receptor, and especially both! And she would be very, very clever if she did this all on her own!
