of this means we have mohamed moneer with us he's a viral legist at lancaster university in england mohamad good to see you a good to have you back on the program so we just heard the c.e.o. of bio on tech there telling you that he is confident that his vaccine in its existing form can be effective against this new virus strain but he cannot be entirely sure given that information do you think that vaccinations could should still go on. yes absolutely one of the prime reason is that this new variant would not really don't provide the vaccine i think is he is that the mutation that we have seen within the spike that the one that makes the cone chip structure on the surface of the widest those are very few compared to the total length of the protein so the antibody response is already against the entire length of the protein so therefore even one or 2 mutations occurred that's not going to completely made the vaccine ineffective so therefore the vaccines that are approved . don't know.
