Vaccine researchers say sorry: no vaccine in time to make a difference

The implications of this statement by vaccine researchers are profound.

They say that a vaccine for Covid19 won’t be found in time to make a difference to the natural outcome of the pandemic.

So is NZ still planning to wait?


It typically takes a minimum of 10 years for a vaccine to complete the three consecutive phases of the clinical research pipeline. This is because of the scope and length of the experiments, the need to critically assess the results at each stage and the mountains of paperwork that are involved.


We contend that a safe and effective vaccine against severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), which is the causative agent of coronavirus disease COVID-19, most likely cannot be made available to the public in time to make a substantial difference to the natural outcome of this pandemic. People often cling to hope even when prospects of success are low. However, this can have negative consequences if that hope is not realized.
