Ongoing Emergence of New COVID-19 Variants

It's been four years since the onset of the COVID-19 pandemic, yet the virus continues to evolve, giving rise to new variants. For many, it feels like an ongoing cycle. In a recent conversation with 22News, an Infectious Disease specialist shared crucial insights into the latest variant and what people need to understand.

Dr. Armando Paez, Chief of the Division of Infectious Disease at Baystate Health, emphasized the persistent presence of COVID-19, particularly during the winter when respiratory illnesses like flu and RSV are also in circulation.

The ever-changing nature of the virus poses challenges in its control. The most recent variant, JN.1, has led to a surge in hospitalizations and deaths. Dr. Paez stressed that vaccination remains the most effective defense against severe illness.

He clarified, "It's still in the family of the omicron, and that means the current vaccination recommended against COVID-19 is still effective in preventing a serious course of illness."

Massachusetts' latest data indicates a moderate level of influenza and a low level of COVID-19 severity. However, vaccination progress against variants is slower compared to the previous year, raising concerns among health officials. The CDC recently issued a health advisory highlighting low vaccination rates for influenza, COVID-19, and RSV.

According to CDC data, only 2 in 5 individuals have received their flu vaccine this season, and approximately 1 in 6 have received the latest COVID vaccine. In Massachusetts, about 19% of residents are vaccinated against COVID-19, while around 38% are vaccinated against influenza. The most vulnerable to severe diseases are older adults and individuals with specific underlying medical conditions.

Dr. Paez emphasized the temporary nature of immunity, noting that reinfection is possible, even with the same variant, depending on the timing and method of vaccination.

Amid concerns about lower vaccination rates, Paez urged individuals to stay vigilant if feeling unwell and to continue preventive measures such as handwashing and mask-wearing. Concerns about unknown or serious side effects have contributed to lower vaccination rates, although health experts assert that side effects are minimal to nonexistent.
