Answer 1

The claim that "no vaccine has ever worked" contradicts reports from global health organizations like the WHO. In a joint press release about a major study published in The Lancet, the WHO states:

"...global immunization efforts have saved an estimated 154 million lives – or the equivalent of 6 lives every minute of every year – over the past 50 years. The vast majority of lives saved – 101 million – were those of infants."

Similarly, a report by the Institute of Medicine (US) Board on Health Promotion and Disease Prevention notes that smallpox was declared eradicated nearly 25 years ago, largely due to the efficacy of the smallpox vaccine, which the report notes "works effectively in both pre-exposure and post-exposure settings."

Answer 2

The claim that "no vaccine, ever, has worked" is false.

An article from the publication Science provides a visualization of CDC data, demonstrating decreasing reports of and, in certain cases, the effective eradication of diseases, following the licensing of vaccines. Our World in Data provides the example of the World Health Organization's global smallpox eradication program, which, from 1959 to 1980, completely eradicated smallpox from the world using vaccinations.

The World Health Organization explains that vaccine efficacy and effectiveness are based on decreased percentages of population contraction and a prediction of effectiveness, respectively. These two measures of success can be hard to quantify, especially in large populations, but the success of vaccines is clear from available data.
