Recombinant proteins are gaining enormous importance these days due to their

wide application as biopharmaceutical products and proven safety record. Various

recombinant proteins of therapeutic and prophylactic importance have been successfully

produced in microbial and higher expression host systems. Since there is no specific

antiviral therapy available against dengue, the prevention by vaccination is the mainstay

in reducing the disease burden. Therefore, efficacious vaccines are needed to control

the spread of dengue worldwide. Dengue is an emerging viral disease caused by any of

dengue virus 1–4 serotypes that affects the human population around the globe. Dengue

virus is a single stranded RNA virus encoding three structural proteins (capsid protein,

pre-membrane protein, and envelope protein) and seven non-structural proteins (NS1,

NS2a, NS2b, NS3, NS4a, NS4b, NS5). As the only licensed dengue vaccine (Dengvaxia)

is unable to confer balanced protection against all the serotypes, therefore various

approaches for development of dengue vaccines including tetravalent live attenuated,

inactivated, plasmid DNA, virus-vectored, virus-like particles, and recombinant subunit

vaccines are being explored. These candidates are at different stages of vaccine

development and have their own merits and demerits. The promising subunit vaccines

are mainly based on envelope or its domain and non-structural proteins of dengue virus.

These proteins have been produced in different hosts and are being investigated for

development of a successful dengue vaccine. Novel immunogens have been designed

employing various strategies like protein engineering and fusion of antigen with various

immunostimulatory motif to work as self-adjuvant. Moreover, recombinant proteins can

be formulated with novel adjuvants to enhance the immunogenicity and thus conferring
