Video transcript

Hello, everyone. Today we have a fine problem. Choose the correct phrase to correct the sentence. A vaccine protects the body against viral diseases by a stimulating the immune system to recognize the response of viral components. Well, this is actually correct. Moreover, it is weakened forms of the virus that stimulate the immune response. Choice B is incorrect as vaccines do not destroy the virus immediately, they only prepare the body for future contamination. Choice C is incorrect as vaccines use weakened forms of viruses, not full strength and in choice D is incorrect as vaccines don't prevent viruses from entry. And so with that, we have solved the problem. Overall, our hope is helped. And until next time.
