Two doses of Moderna or Pfizer-BioNTech’s coronavirus vaccine are very effective in preventing infection, according to a new study from Centers for Disease Control and Prevention (CDC) published Monday.
Researchers looked at the vaccination coverage of nearly 4,000 healthcare workers, first responders, and other essential and frontline workers from mid-December 2020 to mid-March 2021.
The results showed that the risk of infection among fully vaccinated workers was reduced by 90 percent two or more weeks after the last dose – the amount of time it takes to produce antibodies.
In addition, the risk was reduced by 80 percent in people who had just received their first dose of the vaccine.
‘This research shows that our nationwide vaccination efforts are working. The authorized mRNA COVID-19 vaccines provided early, substantial real-world protection against infection for our country’s health personnel, first responders and other essential frontline workers, ” said CDC Director Dr. Rochelle Walensky in a statement.
These findings should offer hope to the millions of Americans who receive COVID-19 vaccines every day and to those who can roll up their sleeves and get vaccinated in the coming weeks. Authorized vaccines are the most important tool to end this devastating pandemic. ‘
It comes as Moderna announced Monday that it has shipped its 100 millionth dose, out of an order of 300 million doses, to the US government.
At the same time, 10 states plan to make all adults eligible for vaccines this week, in line with President Joe Biden’s goal of making every adult eligible for an injection by May 1.
A new CDC study found that front-line workers who received both doses of Pfizer-BioNTech or Moderna’s vaccine reduced their risk of infection by 90% and that one injection reduced the risk by 80% compared to unvaccinated people

For the CDCs study, researchers looked at the vaccination status of 3,950 frontline workers in six states from December 14, 2020 to March 13, 2021.
During that period, 62.8 percent of the workers, or 2,479, received both doses of the Moderna or Pfizer vaccine, and 12.1 percent, 477 workers, received one dose.
The remaining 25.1 percent of frontline or essential workers had not been vaccinated.
Participants were surveyed for symptoms of COVID-19, including cough, fever, chills, shortness of breath, and loss of taste or smell via weekly text messages, email, or in-person appointments.
The workers were given nasal swabs every week, regardless of whether they had symptoms or not, and an additional swab taken if they felt ill.
Over the course of the study, 172 COVID-19 infections were identified. Of these, 161 were among the workers who had not yet been vaccinated.
In comparison, only eight of the partially immunized participants were infected, as well as three of the fully immunized participants.
This means that fully vaccinated workers were 53.6 times less likely to test positive for COVID-19 than those who were not vaccinated.
Even one dose provided substantial protection in partially immunized workers who were 26.8 times less likely to contract the disease than in unvaccinated workers.
According to the CDC, this shows that under real-life conditions, the Moderna and Pfizer vaccines are 80 percent effective after one dose and 90 percent effective after two doses.
“The findings complement and extend these previous reports by showing that the vaccines can also reduce the risk of infection, regardless of the status of COVID-19 associated disease symptoms,” the authors wrote.
The risk of transferable infection..is especially important among health care workers, first caregivers and other key and frontline workers, given their potential to transmit the virus through frequent close contact with patients and the public. ‘
As of Monday morning, 93.6 million Americans, or 28.2% of the population, have received at least one dose and 51.5 million, or 15.5% of the population, have been fully immunized

On Monday, Moderna announced that it had been shipped 100 million doses of his COVID-19 vaccine to the US government.
The company says it expects to honor its agreement with the administration and deliver its second batch of 100 million doses by the end of May and its third batch of 100 million doses by the end of July.
“ I would like to thank the millions of people who have placed their trust in Moderna’s science and our COVID-19 vaccine, ” said Moderna CEO Stéphane Bancel in a statement. statement
“We are encouraged by the fact that more than 67 million doses have been administered in the US and we are humbled to know that we are helping to tackle this global pandemic with our vaccine.
Moderna said his vaccine shipments have increased fivefold – from more than 16 million doses in the fourth quarter of 2020 to 88 million doses in the first quarter of 2021 – since the vaccination received an emergency permit from the U.S. Food and Drug Administration in December.
This week, the U.S. government has ramped up its shipments of COVID-19 vaccines, to about 27 million a week, after about a month of slow weekly deliveries, so states can end vaccinating at-risk groups and make the shots available to everyone.
Ten states – Connecticut, Indiana, Kansas, Louisiana, Minnesota North Dakota, Ohio, Oklahoma, South Carolina and Texas – are making the vaccine eligible for all adults this week.

Twenty-six states have already opened or will become eligible on April 15, and 47 states, and the District of Columbia, have committed to do so by May 1. Pictured: Teachers and school staff in Wylie, Texas receive the COVID-19 vaccine, March 26
This week, 10 states will make vaccines suitable for all adults.
Six of those states – Kansas, Louisiana, North Dakota, Ohio, Oklahoma and Texas – will lift the restrictions for residents 16 and older by Monday.
Minnesota will lift restrictions on Tuesday, Indiana and South Carolina will follow Wednesday and Connecticut on Thursday.
According to the White House, 26 states have already opened or will be eligible on April 15, and 47 states, and the District of Columbia, have pledged to do so by May 1.
This leaves only three states – Arkansas, New York, and Wyoming – that have not yet confirmed plans to extend eligibility before or by the May 1 deadline.
According to the CDC, 93.6 million Americans, or 28.2 percent of the country, have received at least one dose as of Monday morning.
Meanwhile, 51.5 million, or 15.5 percent of the population, are fully immunized, with an average of 2.7 million people getting vaccinated every day.
