    Moderna's vaccine has so far proved the most resistant to "breakthrough coronavirus infections" here at just 0.005 percent.

    According to health authorities on Wednesday, there have been 13,860 breakthrough infections so far or 0.063 percent of the 22.11 million people who are fully vaccinated.

    Those who had been given the Moderna vaccine had the lowest breakthrough infection rate at 0.005 percent, followed by Pfizer (0.043 percent) and AstraZeneca (0.068 percent) vaccines.

    Johnson & Johnson's vaccine had the highest rate at 0.216 percent. The rate among those vaccinated with two different vaccines was 0.051 percent.


    Experts in the U.S. have said that those who have had two shots of the Moderna vaccine do not need a booster shot.

    On Tuesday, U.S. Food and Drug Administration said, "Data indicate that currently U.S.-licensed or authorized COVID-19 vaccines still afford protection against severe COVID-19 disease and death." It added that third shots of the Moderna vaccine increases antibody levels, but no significant difference before and after the booster shot was observed.

    Reversing the FDA's decision to give booster shots to all Americans over 16, the White House has scaled back the targets of booster shots to the over-65s, those with certain chronic diseases, and people in high-risk settings like medical professionals.
