In their research article entitled “Effect of the bivalent HPV vaccine on viral load of vaccine and non-vaccine HPV types in incident clearing and persistent infections in young Dutch females” (2019), Van der Weel et al. concludes that the bivalent vaccine does reduce the amount of HPV 16 and 18 cases while also providing some cross-protective properties that aid in reducing the virus’s viral load. Van der Weel et al. supports their conclusion by obtaining vaginal samples from participants that were vaccinated and unvaccinated, and assessing the viral load of fifteen different HPV strains. The purpose of this research is to demonstrate the efficiency of the HPV bivalent vaccine abilities and limitations so that we could research new vaccines that protect us against more HPV strains. Van der Weel et al. establishes a formal tone with medical researchers, as well as other specialties within the medical field.
