The first single-dose Covid19 vaccine has been released for public usage, which is an incalculable boost to ending the pandemic that has so far killed some 2.5 million and getting some normalcy into the lives of some 10 billion people all over the world.
US regulators last week approved the coronavirus vaccine manufactured by pharmaceutical giant Johnson & Johnson (J&J) which is seen as an excellent alternative to the two-dose Pfizer and Moderna jabs which were introduced earlier.
“This is a game-changer,” according to one US Food and Drug Administration (FDA) official, because aside from being much cheaper, it only needs an ordinary refrigerator for storage, instead of the ultra-cold freezer required by the other two.
What this means, she said, is that the worldwide distribution process to those in need can be greatly simplified and amplified.
Reports said the vaccine, produced by J&J’s Janssen division, is 72 % effective overall; but it is 85% effective when it comes to serious Covid cases.
Bahrain quickly followed suit and gave the vaccine emergency use authorization soon after it was cleared for public use by the US FDA.
On Feb. 27, the American Food and Drug Administration (FDA) granted emergency use authorization (EUA) for Johnson & Johnson’s single-shot Covid19 vaccine, making it the third to be granted distribution and use on individuals 18 years old and above, authority, in the United States.
Clinical trials in the U.S. showed 100% protection against death after 28 days and a 72% prevention rate against moderate to severe illness. Overall, including trials conducted in Latin America and South Africa, the vaccine showed an 85% efficacy rate.
The single-dose vaccine, unlike other vaccines currently in use, can also be stored under regular refrigeration temperatures, foregoing the need for specialized storage equipment.
Meanwhile, the Philippines currently has three vaccines with FDA EUA: Pfizer-BioNTech’s, Astrazeneca’s, and recently, Sinovac’s.
