UNITED Kingdom — Two doses of either Moderna’s or Pfizer-BioNTech’s coronavirus vaccine is highly effective at preventing infection, a new Centers for Disease Control and Prevention (CDC) real-world study published on Monday finds.

Researchers looked at vaccination rates among nearly 4,000 healthcare employees, first responders, and other essential and frontline workers from mid-December 2020 to mid-March 2021.

Results showed the risk of infection among fully vaccinated workers was reduced by 90 percent two or more weeks after the final dose – the amount of time it takes to produce antibodies.

What’s more, the risk decreased by 80 percent among people who had only received their initial dose of the vaccine.

‘This study shows that our national vaccination efforts are working. The authorized mRNA COVID-19 vaccines provided early, substantial real-world protection against infection for our nation’s health care personnel, first responders, and other frontline essential workers,’ said CDC Director Dr Rochelle Walensky in a statement.

‘These findings should offer hope to the millions of Americans receiving COVID-19 vaccines each day and to those who will have the opportunity to roll up their sleeves and get vaccinated in the weeks ahead. The authorized vaccines are the key tool that will help bring an end to this devastating pandemic.’

It comes as Moderna announced on Monday that it has shipped its 100 millionth dose, out of a 300-million-dose order, to the U.S. government.

At the same time, 10 states plan to open eligibility of vaccines to all adults this week, in line with President Joe Biden’s goal of making every adult eligible for a shot by May 1.

So far, just Arkansas and Wyoming -have not yet confirmed plans to expand eligibility ahead of or by the deadline, likely due to clinicians still prioritizing high-risk groups and differences that vary state-by-state in supply and demand of the shots. (AI|Courtesy|MailOnline)
