According to the article, Pesticides are one of the causes that weaken the immune system which leaves them vulnerable to bacteria. There are also the bacteria that this article is directly addressing and mites that suck the fat out of the bees which also kill them. So, yeah this vaccine isn't going to completely stop colony collapse, but it will help a lot of colonies from collapsing that are collapsing because of the bacteria.
