    In an "Perspective", Ravindra Gupta and Eric Topol discuss the efficacy of the COVID-19 vaccine in the context of breakthrough infections and the emergence of new variants
    .

    Although no vaccine can prevent all infections, few can achieve such a high level of protection as the two-dose messenger ribonucleic acid (mRNA) vaccine currently developed to combat SARS-CoV-2
    .

    In a large number of clinical trials (one of the largest trials ever), it was found that the COVID-19 mRNA vaccine has a high level of protection against symptomatic diseases
    .

    However, ongoing research shows that this protective effect will diminish over time, especially in the elderly and people with weakened immune functions
    .

    Recently, in response to the ever-increasing prevalence of breakthrough vaccine infections and new variants of SARS-CoV-2, studies have shown that the third booster dose can restore the effectiveness of the vaccine to more than 90%
    .

    In this regard, Gupta and Topol reviewed recent studies on the breakthrough infection of the COVID-19 vaccine and the efficacy of boosters in preventing SARS-CoV-2 variants (such as Delta)
    .

    The authors concluded that although boosters are important and may last for a while, non-pharmacological interventions, such as wearing masks and maintaining social distancing, not only help reduce COVID-19 cases, but also limit the emergence of evasion Opportunities for immune variants
    .
