Ohio hospitals take out an ad in local paper pleading for people to get vaccinated

Six hospitals in Ohio have taken out a full-page ad in the Cleveland Plain-Dealer in a desperate plea for people to get vaccinated as the state faces a renewed surge.

The ad, which appeared in Sunday’s paper, says in big letters: “Help.”

“We need your help. We now have more COVID-19 patients in our hospitals than ever before,” the ad says. “And the overwhelming majority are unvaccinated. This is preventable.”

Ohio Gov. Mike DeWine announced last week that he would deploy the state’s National Guard to help with hospital strain. Ohio is now averaging more than 9,100 new cases every day — up 67.5% in the last month. Statewide, more than 5,200 patients are hospitalized with COVID-19.

“The best way to avoid serious illness is the vaccine,” the ad said. “So, get vaccinated and get your booster … we need you to care as much as we do.”

Booster shots ‘will really help us’ with omicron: CDC director

About 73% of U.S. COVID-19 cases are now the omicron variant, but that number rises to 90% in areas like New York, CDC director Dr. Rochelle Walensky told “Good Morning America” Wednesday.

“Things are moving quickly,” she said. “The doubling times of this virus are very fast, around two days.”

But Walensky said the booster shot “will really help” with this variant.

“What we know about omicron is that it has a lot of mutations, and with more mutations we need more immune protection. And that’s really why this booster shot will really help us,” Walensky said.

Asked if President Joe Biden’s decision to mail 500 million free at-home rapid tests to Americans in January is too late to help the current surge, Walensky responded, “We have been ramping up testing.”

“We have much more testing now than we had just months ago,” she said. “And we were in the middle of a delta surge as omicron hit, so really right now there are so many things that we can do in addition to testing to keep safe — and that really does mean getting 40 million Americans who continue to be unvaccinated vaccinated and making sure that people get that booster shot.”

Elliot Hospital in New Hampshire is now seeing three to four times as many patients as it had at the beginning of the pandemic, Dr. Laura McPhee told ABC News.
