Understanding the Covid-19 Cicada Variant: Implications for Vaccination

Original: Covid-19 Cicada Variant: Can Current Vaccines Protect Against BA.3.2?

ndtv•Apr 3, 20263 min

In a Nutshell

The new Covid-19 subvariant BA.3.2, nicknamed Cicada, is spreading in the United States and features 70 to 75 mutations in its spike protein. While it may evade some vaccine protections, current vaccines still provide strong defense against severe disease, according to health experts. Monitoring continues as the variant is observed globally.

Key Points

01BA.3.2, or Cicada, is a heavily mutated Omicron subvariant with 70-75 new mutations.
02Current vaccines may offer reduced effectiveness against this variant but still protect against severe illness.
03The variant was first detected in South Africa and has spread to at least 23 countries.
04Health experts recommend vaccination and booster doses, especially for high-risk groups.
05Symptoms associated with Cicada are generally mild, resembling common cold symptoms.

Full Summary

The BA.3.2 Covid-19 subvariant, known as Cicada, has emerged in the United States and is characterized by 70 to 75 mutations in its spike protein, significantly more than earlier variants. The World Health Organization (WHO) has classified it as a Variant Under Monitoring, but assures that the overall risk remains low. Although there is no current evidence indicating that Cicada causes more severe disease, its mutations suggest potential for immune escape from previous infections and vaccinations. Dr. Avi Kumar, a Senior Consultant Pulmonology at Fortis Escorts Heart Institute in Okhla, notes that while the current vaccines targeting JN.1 and LP.8.1 may be less effective against Cicada, they still provide robust protection against severe disease and death, particularly with booster doses. The variant was first identified in South Africa in late 2024 and has since been detected in 29 states in the United States and 23 countries globally. WHO continues to recommend vaccinations, especially for high-risk populations, and advises individuals to stay updated on booster shots and follow health precautions.
