Understanding the Latest COVID-19 Variants: What You Need to Know
As of August 2024, new variants of the COVID-19 virus, including KP.2, KP.3, and LB.1, are becoming more common in the United States. These variants are part of a larger family of mutations known as FLiRT variants, which have developed changes in their genetic structure, making them different from previous versions of the virus.
What Are Variants?
A variant is a version of the virus that has changed (or mutated) from the original. When the virus spreads from person to person, it can mutate, leading to new variants. Some variants spread more easily, are harder for the immune system to fight, or can resist vaccines.
The Latest Variants: KP.2, KP.3, and LB.1
These new variants are spreading quickly in the U.S., with KP.3.1.1 being the most common, making up 37% of new cases. LB.1 and KP.2.3 are also spreading, but at a slower rate. These variants have special changes in their spike protein (the part of the virus that helps it enter human cells) that may help them avoid the protection offered by vaccines.
How Do Vaccines Hold Up?
Vaccines are still a crucial defense against COVID-19, but these new variants might be better at avoiding the immune response created by the current vaccines. For example, KP.2 and KP.3 show resistance to antibodies produced by people vaccinated with the latest vaccine updates. However, vaccines continue to offer significant protection, especially against severe disease and hospitalization.
What Should You Do?

The article from the Infectious Diseases Society of America (IDSA) discusses several key topics related to the current COVID-19 variants, their transmissibility, immunity, diagnostic capabilities, and available therapeutics. Below is a breakdown of these topics in simple terms, suitable for a broad audience.
COVID-19 Variants
As of August 2024, several new COVID-19 variants have emerged, such as KP.2, KP.3, LB.1, and their subvariants. These variants belong to the Omicron family and have specific mutations that make them slightly different from previous strains. Variants like these can spread more easily, escape the immune protection offered by vaccines or previous infections, or even evade diagnostic tests to some extent.
What are FLiRT and SLiP Variants?
FLiRT and SLiP are names given to certain groups of these new variants based on their unique mutations. For example, FLiRT variants have mutations that change specific proteins in the virus, making them more infectious or harder for the immune system to recognize. The “FLiRT” variants include KP.2, KP.3, and LB.1, while “SLiP” variants have slightly different changes.
Immunity and Vaccine Effectiveness
Most people in the U.S. now have some level of immunity to COVID-19, either from vaccines or from having been infected before. However, these new variants, like KP.2 and KP.3, are good at escaping this immunity. This means that even if you’ve been vaccinated or had COVID-19 before, you might still get infected with one of these new variants.
Research suggests that while current vaccines still protect against severe disease, they might be less effective at preventing infection with these new variants. For instance, the JN.1 variant, a predecessor of KP.2 and KP.3, is known for its ability to evade the immune system more effectively than earlier strains. Despite this, vaccines still offer significant protection, especially against severe outcomes like hospitalization and death.
Diagnostic Capacity
Despite the mutations in these new variants, most COVID-19 tests, like PCR and rapid antigen tests, still work well in detecting them. However, as with any test, the accuracy can vary based on the individual’s viral load and whether they have symptoms. It’s important to remember that these tests are constantly monitored to ensure they remain effective as the virus evolves.
Treatment Options
Paxlovid, a treatment for COVID-19, remains effective against these new variants. This drug works differently from vaccines and doesn’t target the spike protein, which is where many of the virus’s mutations occur. This means it’s less likely to be affected by changes in the virus. However, some new variants, like KP.3.1.1, might be less responsive to certain other treatments, like Pemgarda, according to preliminary research.
Conclusion and Disclaimer
In summary, while new COVID-19 variants continue to emerge, vaccines still offer critical protection, and treatments like Paxlovid remain effective. It’s important to stay informed about these developments and consult with healthcare professionals for personalized advice.
