The United States Centers for Disease Control and Prevention (CDC) is sharing some positive information regarding the available COVID-19 vaccines.
According to a recent study from the agency, the Pfizer-BioNTech and Moderna vaccines have proven to be 90 percent effective in preventing infection after receiving a second dose.
“These interim vaccine effectiveness findings for both Pfizer-BioNTech’s and Moderna’s mRNA vaccines in real-world conditions complement and expand upon the vaccine effectiveness estimates from other recent studies and demonstrate that current vaccination efforts are resulting in substantial preventive benefits among working-age adults,” the CDC study read.
For those who are only partially immunized, meaning they only received one dose of the vaccine, Pfizer and Moderna have proven to be 80 percent effective.
The study took place in 8 different cities with weekly COVID testing taking place for 13 weeks in a row.

The coronavirus originated from animals and a majority of those who were infected early either worked at or frequently visited the Huanan seafood wholesale market in Wuhan, according to The Guardian. The virus is similar to Severe acute respiratory syndrome (Sars) and Middle Eastern respiratory syndrome (Mers).
The Wuhan coronavirus is transmitted from person to person through “droplet transmission.” That means an infected person can pass the virus by sneezing or coughing on another person as well as by direct contact.
While a majority of the cases have been detected in the United States and China — with more than 30.3 million confirmed cases and 549,000 deaths in the United States — it has now reached many countries around the world. It has also been confirmed in Italy, Australia, Canada, France, Germany, and many other eastern countries.
