The pharmaceutical companies say the vaccines can be tweaked to address new strains of the virus and the FDA has said it would work to streamline the approval process for these updated vaccines. Under European law a vaccine must be authorised by the EMA but individual countries can use an emergency procedure that allows them to distribute a vaccine for temporary use in their domestic.
