THIRD COVID-19 VACCINE GIVEN EMERGENCY USE AUTHORIZATION:
Johnson & Johnson Covid-19 vaccine has been authorized and is being distributed this week.
The vaccine can be given to anyone 18 years and older and is one injection given in the arm.
Full protection was tested 28 days after vaccine administration.
The Johnson & Johnson vaccine is:
*72% effective in protecting against moderate to severe Covid disease
*85% effective against severe Covid disease.
The effectiveness of Johnson & Johnson vaccine sounds less than Pfizer and Moderna vaccines, but Johnson & Johnson was tested in South Africa where one of the new variants was found and Pfizer’s and Modern’s effectiveness wasn’t tested against any of the variants at the time it was FDA approved.
Moderna and Pfizer are currently working on booster shots to work against Covid variants.
Johnson & Johnson is currently working on a second shot to help increase efficacy.
