(CNN) Covid-19 vaccination rates are down and cases are on the rise, exacerbated by the more transmissible Delta variant -- and an expert says the key to winning the race against the spread is getting more Americans vaccinated. Much of the data now shows that more than 99% of people currently hospitalized with Covid-19 are unvaccinated, Collins said. And the vaccines are still showing signs of being very effective against the Delta variant, he said, which is one of the greatest concerns for health experts currently. Through the Vaccines for Children (VFC) program, the CDC purchases vaccines and distributes them to clinics and physicians' offices. A CDC spokesperson said states, physicians' offices and others ordered 98.7 million doses of vaccines under the program in 2019.
