So here's the story:
This time last year, the brand new, stunningly effective Covid-19 vaccines were rolling out across the country, injecting a strong note of optimism into the United States' once fumbling pandemic response.

And here's the operative parts:
Like the virus that causes Covid-19, the measles virus spreads through the air. It is so contagious that if one person has it, 9 out of 10 people around them will catch it if they are not immune to it,
according to the CDC. Some experts have estimated that the Omicron viruses are as contagious as the measles.
The US eliminated transmission of measles and has successfully kept the virus from circulating in this country because of three things: an extremely effective vaccine; a virus that doesn't change, or mutate, in significant ways over time; and a successful childhood vaccination campaign.
The measles vaccine is 97% effective at preventing the disease,
according to the CDC. Once a person is vaccinated, studies have determined that protection lasts virtually their whole lives.
Many states in the US had once reached an ambitious public health goal of getting more than 90% of their children vaccinated against the disease by the time they started kindergarten.
This high level of vaccination coverage, the durability and effectiveness of the vaccine, and the relative stability of the virus have helped the United States prevent major outbreaks of the disease for more than 20 years.
Covid-19, unfortunately, isn't playing by those same rules.
"Bad news number one," said Fauci, is that the coronavirus that causes Covid-19 changes a lot and in significant ways.
"We've already experienced over a period of two years that we've had five separate variants Alpha, Beta, Delta, Omicron. And now BA.2 from Omicron one," he said.
"Bad news number two is that there's a lack of a wide acceptance of safe and effective vaccines," Fauci said. Put simply, not enough people have been vaccinated.
