COVID-19 updates: American Airlines to require employee vaccinations

The CDC reports that 77% of adults have gotten at least one vaccine dose. 

Vaccinations have gone up since August, and a study by health policy research organization Kaiser Family Foundation indicates that gaps by race and ethnicity are almost eliminated -- 73% of Hispanics, 71% of white people and 70% of Black people are said to be vaccinated.

However, vaccine gaps persist across party lines -- KFF found that 90% of Democrats say they’ve gotten at least one dose of the vaccine, compared with 68% of independents and 58% of Republicans.

However, unvaccinated people continue to express doubts concerning the vaccines’ effectiveness and resistance to vaccine mandates in the workplace. 

In a poll by the Axios/Ipsos Coronavirus Index, 71% of unvaccinated Americans believe that the vaccine booster shots and breakthrough infections are signs that vaccines are not as effective as they are said to be. 

Only about 29% of unvaccinated workers say they would get a shot if their employer mandates it, according to the Axios/Ipsos Coronavirus Index.

Merck Thursday morning announced the results of an ongoing Phase 3 study of an antiviral pill that may slash the risk of being hospitalized or dying of the virus by 50%.

The study's results are so compelling that an independent monitoring board recommended, in consultation with the FDA, ending the trial early so the companies can swiftly seek authorization.

Since the beginning of September, the U.S. has seen a drop of more than 27,000 patients in hospitals across the country, according to federal data. A little less than half of those patients come from Florida.

Daily hospital admissions are down by nearly 15% in the last week and by 32% in the last month, according to federal data.

The country's daily case average has fallen to 107,000 -- a 33% drop in the last month. However, about 97% of counties are still reporting "high" or "substantial" community transmission.

Aladdin will return to Broadway Thursday night after Wednesday's show was canceled due to several people in the production testing positive for COVID-19.

All members of Disney Theatrical's companies must be vaccinated.

"Our extensive protocol system to test our employees and identify positive cases worked, and allowed us to act immediately to contain those cases," production said. "Given the thoroughness of our Covid protocols and a vaccinated workforce, we remain confident that the environment is safe for our guests, cast, crew and musicians."

Disney Theatrical Productions is a part of the Walt Disney Company, the parent company of ABC News.
