U.S. health experts continue to raise alarm over the country's slow vaccine rollout. As of Tuesday morning, just 4.8 million vaccine doses had been administered across the country, out of a total 17 million doses distributed to administration sites, according to the CDC. CVS Health said Wednesday it's on pace to complete the first round of vaccinations at long-term care facilities by Jan. 25. The company also said a small number of vaccine doses could be made available at pharmacy locations in the coming weeks ahead of a broad rollout. Experts have recommended a number of changes to improve the pace of vaccinations, including broadening early eligibility and reducing stored capacity for second doses.
