Biggest hope is synthetic antibody therapy than vaccine ..because vaccine may not work with old people and those with low immunity ..but synthetic antibody therapy will as they have specific neutralizing antibody ..lot of companies are making progress including here in Canada ...fisrt one from regeneron USA in now in last stages of clinical trails ..they are making synthetic antibody cocktail ..they successfully made it for Ebola ...if this works for covid ..that will be beginning of end of this pandemic...i expect some psositive news by end of this year..or else situation will get worse...plasma therapy from blood is not working that good because most recovered people blood don’t have quality neutralizing antibodies...synthetic one will be an answer for this...
