Exploring the Enigma of the ‘Pirola’ COVID-19 Variant: What We Know So Far

Amid the COVID-19 landscape, a new variant known as ‘Pirola’ has piqued the interest of researchers due to its multitude of mutations, raising questions about its potential impact on the United States and the world.

The Centers for Disease Control and Prevention (CDC) has been closely monitoring this variant, which stands out with its distinct genetic alterations compared to earlier versions of the virus. Mandy Cohen, the director of the CDC, acknowledges the unique features of ‘Pirola’ in a recent video statement, emphasizing the need for vigilance.

However, our grasp of ‘Pirola,’ formally identified as BA.2.86, remains elusive due to the declining trend in global COVID-19 data collection. Maria Van Kerkhove of the World Health Organization underscores the challenges posed by diminishing surveillance, reduced testing, and delayed sequencing availability, hampering the organization’s ability to assess the variant’s characteristics effectively.

So, What Do We Know About ‘Pirola’?

BA.2.86 is a subvariant of the Omicron strain, boasting over 30 mutations, a striking parallel to the evolutionary leap observed with the original Omicron variant, BA.1.

The CDC’s risk assessment acknowledges ‘Pirola’ as a noteworthy development, as it diverges significantly from previous SARS-CoV-2 variants. This variant has been detected in limited samples from infected individuals and wastewater across multiple countries, including the United States.

However, ‘Pirola’ has been categorized by the WHO as a “variant under monitoring,” indicating genetic changes that could affect its characteristics, such as transmissibility. Yet, limited evidence hampers a clear understanding of its impact.

Recent laboratory tests conducted by several U.S. research teams offer a glimmer of insight. These preliminary results suggest that individuals’ immune systems respond adequately to ‘Pirola,’ sometimes even surpassing responses to other circulating strains.

Despite limited data on this variant, initial findings suggest it may not be as concerning as initially feared. While questions remain about its competitiveness and severity, the presence of antibodies offers a ray of hope. Nevertheless, the emergence of ‘Pirola’ underscores the importance of maintaining genomic surveillance capabilities.

Where Has ‘Pirola’ Been Spotted?

Since late July, ‘Pirola’ has surfaced in small numbers across 11 countries, including Denmark, Sweden, Portugal, Israel, the U.K., the U.S., Canada, and South Africa. Although it is spreading, it has not yet outcompeted other strains. This complex global landscape indicates that different variants circulate at different times in different countries.

Will Vaccines Be Effective Against ‘Pirola’?

Optimism surrounds the efficacy of booster shots against ‘Pirola’ and other circulating strains. The CDC anticipates that the updated COVID-19 vaccine, set to be available in mid-September, is likely to reduce severe disease and hospitalization.

Moderna and Pfizer have reported promising results, indicating that their updated vaccines generate a robust immune response against ‘Pirola.’ These findings reaffirm the vaccines’ significance in safeguarding public health as the vaccination campaign for the fall season unfolds, with updated shots expected to roll out in the U.S. shortly.
