The authors Min-Jean Yin and Rounak Nassirpour and a Pfizer representative contacted the editorial office to raise that there are image duplications in Figure 4B of this article. Pfizer has undertaken a review and deemed that important conclusions in the manuscript cannot be verified, as original images cannot be located.
In light of the concerns identified, the authors and the PLOS ONE Editors retract this article. We did not receive any response or comment from Pramod Mehta.
