ACIP recommends vaccination with Dengvaxia for children aged 9–16 having evidence of a previous dengue infection and living in areas where dengue is endemic.

How long does dengue immunity last?

Serological methods. Serological methods, such as enzyme-linked immunosorbent assays (ELISA), may confirm the presence of a recent or past infection, with the detection of anti-dengue antibodies. IgM antibodies are detectable ~1 week after infection and remain detectable for about 3 months.

What brand is Dengvaxia?

Sanofi Pasteur Inc. (SNY) is the manufacturer of the Dengvaxia vaccine.

What is the problem with dengue vaccine?

In 2019 it was approved for medical use in the United States. It is on the World Health Organization’s List of Essential Medicines.

Can your immune system fight dengue?

To fight the infection, the immune system produces antibodies to neutralize the dengue viral particles, and the complement system is activated to help the antibodies and white blood cells remove the virus. The immune response also includes cytotoxic T cells (lymphocytes), which recognize and kill infected cells.
