This includes highly sensitive polymerase chain reaction, or PCR, tests, which evaluate the presence of viral RNA in a sample, along with rapid tests that check for viral proteins, or antigens. Both Covid-19 and the flu often cause symptoms such as fever, fatigue, body aches, sore throat, shortness of breath and . Gilead, the maker of the antiviral drug remdesivir, which works by inhibiting viral replication via the viral polymerase, said in a Dec. 1statementthat analysis of omicron sequences does not show any new mutations in the polymerase, so it expects the drug to be active against the variant. Miller said that although she would not be surprised if omicron indeed does show up in the throat before it does in the nose, that concrete data has yet to be shown.

But the reality is that there wont be an Omicron-matched shot available for months he said in an email. Omicron has a few more mutations than beta at key places, so it could be that the 3, (unmatched) dose will do a bit worse than it did against Beta.
