Coronavirus replace: US tries to fill gaps in therapy for COVID as Delta variant is inflicting worrying spike in new instances within the UK.

The U.S. plans to invest $ 3.2 billion in developing antiviral drugs to treat COVID-19 and other viruses that have the potential to become pandemics.

A new program will invest in "speeding up things that are already happening" for COVID-19, but also developing treatments for other viruses, said Dr. Anthony Fauci, the country's foremost infectious disease expert and chief medical officer to President Joe Biden's officer, reported to the Associated Press.

However, Fauci stressed that vaccines would remain the primary tool in fighting COVID as research advances to find better treatments than Gilead's existing antibodies and antiviral remdesivir, which come with onerous logistical hurdles as most of IV must be administered in a hospital setting. Health professionals are increasingly demanding a convenient pill that patients can take themselves when symptoms first appear.

The news comes amid growing concerns about the spread of new variants of COVID, and in particular the Delta variant, a highly contagious strain first discovered in India. This variant is behind a surge in infections in the UK, despite the fact that that country has vaccinated more than 80% of its adult population.

The UK recorded 11,000 daily cases on Friday for the first time since February as the new variant spreads rapidly. The Centers for Disease Control and Prevention agreed with the World Health Organization earlier this week by declaring the Delta variant "of concern," a more worrying assessment than its previous "of concern."

The U.S. vaccine program, meanwhile, continues to slow, with the number of fully vaccinated Americans rising to 147.8 million or 44.5% of the total population on Friday, up from 44% on Thursday, according to the CDC's vaccine tracker. Approximately 176 million Americans have received at least one dose of the two-dose vaccines developed by Pfizer Inc.

Among adults aged 18 and over, 55.2% of the population are fully vaccinated. Among adults over 65 years of age, 42 million people, or 76.8% of this group, are fully vaccinated and 87% of this cohort have received at least one vaccination.

The rest of the world looks very different, however.

As the map above shows, parts of Africa have vaccinated less than 1% of their population. According to Johns Hopkins University, a total of 2.5 billion doses have been administered worldwide. According to a recent New York Times report quoting research from Duke University, it takes about 11 billion doses for the world to vaccinate 70% of its population.
