Distinguishing between primary measles infection and vaccine failure reinfection by IgG avidity assay.

چکیده
In this study in the Islamic Republic of Iran 365 measles cases were evaluated to distinguish between primary infection with measles and reinfection due to secondary vaccine failure. All cases previously confirmed by detection of specific IgM were tested for IgG avidity. A secondary immune response was seen in 18.4% of patients. All unvaccinated patients (16.7%) showed a primary immune response. Of 244 patients with documented vaccination, 75.8% showed a primary immune response and 24.2% showed a secondary immune response, thereby indicating a secondary vaccine failure. Almost all measles reinfections (99%) were seen in patients >10 years old, indicating that vaccination for 10-year-old children is recommended.

Distinguishing between primary infection and reinfection with rubella vaccine virus by IgG avidity assay in pregnant women.
During the mass measles/rubella vaccination campaign in 2003 in Iran, many pregnant women were vaccinated mistakenly or became pregnant within 1 month of vaccination. To distinguish pregnant women who were affected by rubella vaccine as primary infection from those who had rubella reinfection from the vaccine, serum samples were collected 1-3 months after the campaign from 812 pregnant women. I...

Background and purpose: Primary cytomegalovirus (CMV) infection occurs in 0.15-2.0% of all pregnancies and might causes abortion. Actually CMV infections are most common in females and rate of infection increases with age. In pregnant women it usually occurs in ages below 30 years old. Aim of the present study was investigating on the seropositivity rate of CMV in pregnant women to determine th...

In the United States, approximately 9% of the measles cases reported from 2012 to 2014 occurred in vaccinated individuals. Laboratory confirmation of measles in vaccinated individuals is challenging since IgM assays can give inconclusive results. Although a positive reverse transcription (RT)-PCR assay result from an appropriately timed specimen can provide confirmation, negative results may no...
متن کاملIdentification of primary and secondary measles vaccine failures by measurement of immunoglobulin G avidity in measles cases during the 1997 São Paulo epidemic.
Despite almost universal use of measles vaccines in recent decades, epidemics of the disease continue to occur. Understanding the role of primary vaccine failure (failure to seroconvert after vaccination) and secondary vaccine failures (waning immunity after seroconversion) in measles epidemics is important for the evaluation of measles control programs in developing countries. After a measles ...
