Vaccine development and Production
Vaccine
development involves a combination of public and private and it is a long and
complicated process which lasts for around 10- 15 years. Not all vaccines that
are designed gets licensed only tiny percentage of candidate vaccines
are licensed. This makes the vaccine research
and development costs higher. Vaccines are
first designed in laboratories and assays are made with animals before they are
tested with humans. The vaccine
production cycle is quite different from a pharmaceutical product
development since vaccines
are biological products made from microorganisms. The challenging factors which
makes the vaccine development
little complicated includes the identification of suitable antigens, delivery
methods which are acceptable, adjuvants, difficulties in manufacturing.
