Background: With the release of two vaccines after FDA approval, we are entering phase IV or as it is called Post-marketing phase. This phase is responsible for the mass vaccination and the herd immunity we need to end the pandemic.
Methods: the author searched PubMed for the keywords “Vaccine, COVID-19, and SARS-CoV2”, along with following the announcements of the various scientific communities.
Results: No phase IV trial data has been published till the time being, but only published data of Phases I-II and III were found by the literature search. The author discussed the limitations of the studies and the promised outcomes measured in those studies.
Conclusions: Waiting for phase IV data yet to be published; the author has examined the benefits and limitations of each vaccine.
