FDA Approves Johnson & Johnson’s Single-Dose COVID Vaccine

A new COVID-19 vaccine is on the market and it is the first of its kind, according to CNBC.

On Saturday, February 27, the US Food and Drug Administration approved Johnson & Johnson’s single-dose COVID vaccine for emergency use.

The vaccines that are currently on the market — from Pfizer and Moderna — require two doses for the full effect, but Johnson & Johnson has been working on a single-dose vaccine in an effort to make widespread vaccination more efficient.

Following studies earlier this month, the Johnson & Johnson single-dose vaccination has proven to be safe and approximately 66 percent effective in preventing severe cases of COVID-19.

The Johnson & Johnson vaccine can also be shipped at more reasonable temperatures than its competitors, which could help with distribution.

From the report:

The company has said it plans to ship the vaccine, which contains five doses per vial, at 36 to 46 degrees Fahrenheit. By comparison, Pfizer’s vaccine needs to be stored in ultra-cold freezers that keep it between minus 112 and minus 76 degrees Fahrenheit, though the FDA recently allowed the company to store its vaccine for two weeks at temperatures commonly found in pharmaceutical freezers. Moderna’s vaccine needs to be shipped at 13 below to 5 degrees above zero Fahrenheit.

No severe side effects were recorded following the vaccine.

The coronavirus mainly comes 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 28.5 million confirmed cases and 511,000 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.
