Study Shows J&J Coronavirus Shots are Boosted Better by Moderna & Pfizer

A study conducted by the National Institutes of Health has revealed that the people who received the Johnson & Johnson’s COVID-19 vaccine as a first shot have a more robust immune response if they are given a Pfizer/BioNTech or Moderna booster vaccine.

The study included more than 450 adults who had received either Pfizer’s, Moderna’s, or Johnson & Johnson’s initial shots and found that “mixing and matching” different types of booster shots are completely safe for adults.

Although the study is in its initial stages and has not been peer-reviewed, its results are the latest challenge to Johnson & Johnson’s efforts to proffer the use of its coronavirus vaccine as a booster shot in America.

America had previously announced that it will accept the coronavirus vaccines that have been authorized by either US regulators or the World Health Organization for international travelers.
