Public Health Alerts provide concise, data-driven information on disease outbreaks and urgent health events. The new series, launched by NEJM Evidence and CIDRAP, offers expert-reviewed reports to support public health evidence-based care.
Researchers discovered a new evasion strategy used by the varicella zoster virus to affect tissues far from the original site of infection. The virus uses small extracellular vesicles (sEVs) to package and shuttle a protein called IE62, which can travel to distant cells and shut down their antiviral response.
A recent study by Finnish Institute for Health and Welfare reveals that the two-dose varicella vaccination programme significantly reduced health centre appointments related to chickenpox among children under 12. The number of cases decreased by more than 95% in 2022 compared to pre-vaccination levels.

A new study published in the Journal of the Pediatric Infectious Diseases Society finds that US chickenpox cases have declined by 93% since the introduction of the vaccine in 1995, thanks to increased vaccination coverage. This decline is attributed to herd immunity, which protects those who are not immunized themselves.
Researchers at Bar-Ilan University develop novel experimental model that successfully mimics the re-activation of the varicella-zoster virus, which causes chickenpox and shingles. The model allows scientists to test drugs and develop therapies to prevent shingles and potentially impact other viruses targeting the human nervous system.
A new study finds that shingles significantly increases the risk of stroke in the first six months after symptoms appear. However, patients treated with oral antiviral medication for their shingles may experience lower stroke risks compared to those not treated.
A 14-year study found the varicella vaccine to be approximately 90% effective in preventing chicken pox, with a significant decrease in breakthrough cases over time. The second dose of varicella vaccine was found to be unnecessary for prevention of moderate to severe disease.

A new study confirms that two doses of the varicella, or chickenpox, vaccine provide excellent protection in children against this highly contagious and, in some cases, severe disease. The study found that the effectiveness of two doses of vaccine was 98.3 percent in protecting against varicella, significantly higher than one dose.
A Kaiser Permanente study found the MMRV vaccine doubles the risk of febrile seizures in 1- to 2-year-old children compared to separate MMR and varicella vaccines. The study analyzed 459,000 children and recommended that families without a preference for MMRV receive separate vaccinations.
A study found that refusing the varicella vaccine is associated with a nine-fold increased risk of developing the disease in children. This finding suggests that declining vaccination rates could lead to an increase in the incidence of chickenpox and related complications.
A Kaiser Permanente study found that the chicken pox vaccine significantly reduces the risk of shingles among children. The study followed over 170,000 vaccinated children for an average of two and a half years, resulting in only 122 cases of herpes zoster.
Researchers at UT Medical School in Houston found that knowing a blood relative with shingles doubles one's risk of getting the condition. The study recommends vaccination for individuals with family history to prevent shingles outbreaks.
New research from the Mayo Clinic suggests that shingles and its complications may have a greater impact on healthy adults than previously thought. The study found that shingles affects at least 1 in every 278 adults each year, with post-herpetic neuralgia being the most common complication, especially among older adults.
