Dengue fever has no specific treatment, but supportive care can help manage the symptoms. Only one vaccine, Dengvaxia® from Sanofi, has been approved by the FDA to prevent severe disease. It is approved for children aged 9 to 16 who live in an endemic area and have previously been infected with DENV as confirmed by a laboratory serological assay.
Less than a year after the World Health Organization (WHO) declared COVID-19 a global pandemic, the authorization of several novel COVID-19 vaccines has created hope for a healthier future. Recent studies have demonstrated that both humoral and cellular immunity play a role in protection from COVID-19. Additionally, the development of novel COVID-19 vaccines requires a look at the immune response in order to determine the effectiveness of the vaccine at preventing infection.
