how to combine 2 grep checks in a while loop

This is basically what I'm trying to do:

while string1 is not present in foo.log OR string2 is present in foo.log do
    echo .
loop

Examples of input files:

this should keep the while running

string1
foo
bar
string2

this should keep the while running

foo
bar

this should stop the while loop

foo
bar
string1

"string1 is not present in foo.log OR string2 is present in foo.log" should translate to

while ! grep -q "string1" foo.log || grep -q "string2" foo.log; do
    echo .
done
