Key result
Active prevention and unified prophylaxis standards are needed to combat rising varicella in pregnant women.
Why the study?
Chickenpox during pregnancy causes life-threatening complications, yet low immunization, lack of pre-pregnancy screening, and rising incidence exacerbate maternal risk.
Highlights the need for active chickenpox prevention and unified standards for post-exposure prophylaxis in pregnant women in the Russian Federation.

Does not yet change clinical practice; leaves open whether unified prophylaxis standards improve outcomes in pregnant women.
Chickenpox during pregnancy can lead to life-threatening complications for the mother and various forms of intrauterine infection. The rising incidence of varicella in the Russian Federation, low rates of immunization, lack of pre-pregnancy screening for antibodies to human herpesvirus type 3, and the availability of vaccination only at the pregravid stage contribute to the epidemiological involvement of pregnant women. Low public awareness about the possibility of varicella immunoprophylaxis, along with insufficient caution among healthcare professionals regarding the potential risks of chickenpox during pregnancy, also exacerbate this issue. The solution to this problem is based on an active approach to chickenpox prevention to create a safe environment for pregnant women and to develop unified standards for post-exposure prophylaxis of chickenpox in pregnancy.

Koltsova et al. (2025) conducted a review in Chickenpox and herpes zoster in pregnancy. Varicella immunoprophylaxis and prevention was evaluated. Active approaches to chickenpox prevention and unified standards for post-exposure prophylaxis are needed to address rising varicella incidence and low immunization rates among pregnant women.
