Moderna vaccines (RNAm) – Get the report and Pfizer / BioNTech (PFE) – Get the report (BNTX) – Get the report are “very effective” at preventing COVID-19 infections among essential workers, health officials said on Monday, while warning that the United States faces an “imminent catastrophe” due to the increase in cases of disease.
Rochelle Walensky, a doctor who heads the Centers for Disease Control and Prevention, during a press briefing Monday, made her comments as the number of COVID-19 cases began to rise again.

“I’m going to take a break here, I’m going to lose the script, and I’m going to reflect on the recurring feeling I have of impending doom,” Walensky said.
Many states are relaxing their pandemic restrictions, and more Americans are traveling.
The United States records a weekly average of 63,239 new cases of Covid-19 per day, up 16% from a week ago, according to a CNBC analysis of data compiled by Johns Hopkins University.
Nearly 550,000 people died from COVID-19 in the United States on Monday, with 30.3 million cases reported.
“We have so much to look forward to, so much promise and potential from where we are and so much to hope for, but right now I’m scared,” Walensky said.
Meanwhile, the CDC said a new study has provided strong evidence that vaccines are very effective at preventing infections “under real conditions among healthcare workers, first responders and other essential workers.”
The results showed that the risk of infection was reduced by 90% after the second dose of the vaccine, which is the recommended number of doses, two weeks or more after vaccination.

“This study shows that our national immunization efforts are working,” Walensky said in a statement.
The risk of infection was reduced by 80% after a single dose of either vaccine, two weeks or more after vaccination.
The study looked at the effectiveness of the Pfizer-BioNTech and Moderna vaccines on 3,950 participants in six states for 13 weeks from December 14, 2020 to March 13.
Participants provided nasal swabs every week for testing. The majority of infections have occurred in people whose infections were identified by tests before they developed symptoms or knew they were infected.
The study shows that vaccines can reduce the risk of all infections, not just symptomatic ones.
Moderna shares at the last check were down 8.2% to $ 112.46, while Pfizer was 1.2% higher at $ 36.39. Shares of BioNTech rose 0.4% to $ 96.13.
Moderna said on Monday that it had completed sending the first 100 million doses of its coronavirus vaccine to the US government.
He also said he was on track to deliver a second batch of 100 million doses by the end of May and a third batch by the end of July.
Pfizer said last week it had started testing the human safety of a new pill that could be used to treat COVID-19 as soon as symptoms first appear.
