The effectiveness of all three coronavirus vaccines available in the United States has dropped substantially after six months, new research published in the journal Science reveals.

The most dramatic drop was from Johnson & Johnson’s shot, whose effectiveness plummeted to 13.1 percent in September from 86.4 percent in March.

During the same time period, Pfizer’s vaccine also fell below the 50 percent effective mark to 43.3 percent from 86.9 percent when it was first administered.

Moderna’s effectiveness declined the least, but was still significant at 58 percent from 89.2 percent.
