However, these efforts have improved significantly in recent weeks, primarily at $ 1.75 billion. Funding for Genome Sequencing In Stimulation package Mr. Biden signed the law last month. In contrast, the United Kingdom, which has a more centralized medical system, launched a highly facilitated sequencing program last year that allows it to track the spread of B.1.1.7 variants.
