00:00:01.940 --> 00:00:05.480
A study conducted in Israel found that the Pfiser COVID-19

2
00:00:05.480 --> 00:00:09.349
vaccine is somewhat less effective against the more infectious delta

3
00:00:09.349 --> 00:00:11.900
variant, though it was still found to be effective

4
00:00:11.910 --> 00:00:14.980
at preventing severe illness. As the Wall Street Journal

5
00:00:14.980 --> 00:00:19.250
reports, the Pfizer vaccine protected 64% of immunized people

6
00:00:19.250 --> 00:00:21.739
during an outbreak of the Delta variant, a sharp

7
00:00:21.739 --> 00:00:24.530
drop when compared to the 94% of people it had

8
00:00:24.530 --> 00:00:27.379
previously been shown to protect. However, the shot

9
00:00:27.379 --> 00:00:31.199
was still 94% effective at preventing severe illness, a

10
00:00:31.199 --> 00:00:34.950
slight decrease from the 97% that were kept from experiencing

11
00:00:34.950 --> 00:00:36.659
severe illness previously.
