Dear Sir,

Varicella is a common viral infection. It is highly contagious and can be problematic in disease control. The medical personnel are at high risk to come in contact and vaccination is recommended for them.[1] However, in many developing countries, the disease is common and many local people have immunity due to previous infection. In many settings, including Thailand, the seroprevalence study shows high rate of immunized local people and, hence, vaccination is not recommended.[2] However, due to improved sanitation, the situation can be changed. As it is an expensive vaccine, in many settings, it is required that medical personnel have their blood test done before getting the varicella vaccine. The specific concern group is the health-care worker students who first come in contact with real patients during clinical study.[3] Here, the authors report the observation from our settings on varicella seropositivity among nursing students before clinical year practice. Of overall 62 students receiving screening, the seropositivity of varicella immunoglobulin G (IgG) test can be seen in 42 cases (67.7%). This can show that there are a number of cases who still require vaccination. Further study to assess the option for screening and vaccination for varicella in our setting is planned. Briefly, based on our situation, it can be seen that the cost for mass screening for varicella serology in 62 cases is equal to 930 USD (15 USD/screening). If there is no screening and mass varicella vaccination is done, the cost of vaccination will be 1,860 USD (30 USD/vaccination). In case that prevaccination screening is used, the cost will be equal to the cost of mass screening (930 USD) plus cost of vaccination in seronegative case (600 USD) that is equal to 1,530 USD. This can show that the prescreening before vaccination is cost effective. Nevertheless, further assessment in different settings with different seroprevalence has to be done for validation of the findings.
