Doctors who scrutinized existing Covid 19 vaccines determined that not one of them can stop the virus from infecting an individual, but the infection will be mild if the person has been inoculated days prior to infection and, all vaccines are equally able to save lives and prevent the condition of the victims from deteriorating.

That's according to Dr. May Emmeline Motellano, Adviser of Philippine Foundation for Vaccination, and  member of the National Immunization Technical Advisory Group for Covid 19 in the Philippines who was interviewed in this episode.
