Which covid ward do you work in ? Certainly is a contrast in stories out there ! It is really hard to work out what to believe ! Having said that, how is it possible for a vaccine that was produced targeting the initial Covid strain, to now work effectively ion a completely new mutant strain which is delta ! This appears to be in stark contrast to the flu vaccines, where an initial vaccine is useless against new strains of a seasonal flu or cold as I understand the clinical data?
