The authors would like to correct the title of the above paper.

The published title is “A Randomized Controlled Trial of Oral Administration of Tetanus Toxoid (TT) Versus Tetanus and Reduced Diphtheria (Td) in Pregnant Women”. The correct title is shown above. The words “of Oral” were removed since this vaccine is not given orally but instead should be injected.
