Screening is more effective than vaccination in reducing mortality from hepatitis B, and vaccinating close contacts also provides significant benefits.
A new study found that irregular Pap smears and false negative tests were not the primary reasons for cervical cancer development. Instead, socio-economic disparities in screening access may be a major obstacle to eradicating the disease.
A study found that childhood vaccination for the rubella virus may have eliminated an inflammatory eye disease from the U.S.-born population. The vaccine was implemented in 1969, and subsequent reductions in Fuchs heterochromic iridocyclitis (FHI) cases were observed, especially among foreign-born patients.
Maternal and neonatal tetanus can be eliminated with effective action, including vaccination and proper care practices. However, sustaining elimination may require improvements in immunization and health services.
