Vaccines which use killed or inactivated germs are called dead or inactivated vaccines. Other types are subunit vaccines, which only use parts of germs.
The global vaccines market is expected to reach $57.50 billion by 2025 from $33.70 billion in 2018, growing at a CAGR of 7.9%
The growth of this market is mainly attributed to high prevalence of diseases, increasing government initiatives towards immunization, rising adoption of vaccines, technological advancements in vaccine industry, and strong pipeline for vaccines. In addition, increasing epidemic potentials and growing focus on therapeutic vaccines are expected to offer significant growth opportunities for players operating in the vaccines market.
In 2017, pneumococcal disease accounted for the largest share of the vaccines market. The large share of this segment is mainly attributed to high prevalence of pneumococcal disease in pediatric, elderly, and immunocompromised populations. In addition, growing number of pneumococcal diseases associated with chronic disease patients is further driving the adoption of the pneumococcal vaccines.
The route of administration is the lane by which a vaccine is brought into contact with the body. Vaccines are administered through Intramuscular (IM), Subcutaneous (SC/SQ), oral, and others (intradermal and nasal). In 2017, the intramuscular accounted for the largest share of the of the global vaccines market. The large share of this segment is mainly due to availability of wide range of vaccines for IM.
Subunit, recombinant, polysaccharide, and conjugate vaccines accounted for the largest share of the global vaccines market in 2017. The large share of this segment is mainly attributed to increasing focus of companies towards recombinant and conjugate vaccines, growing prevalence of diseases, and increasing government initiatives.An in-depth analysis of the geographical scenario of the industry provides detailed qualitative and quantitative insights about the five major geographies (North America, Europe, Asia-Pacific, Latin America, and Middle East & Africa) along with the coverage of major countries in each region. North America accounted for largest share of vaccines market in 2017. The large share of this segment is mainly attributed to the well established vaccination program in the region, increasing prevalence of diseases, growing adoption of advanced vaccines, and large pool of key players. The Asia-Pacific vaccines market is expected to grow at a highest CAGR of 8.9%. The growth in the APAC market is mainly attributed to large patient pool, rising prevalence of diseases, growing awareness on vaccination, increasing government initiatives, and expanding presence of key players in this region. In addition, factors such as increasing disposable income and growing awareness about heath in emerging countries are further propelling the demand of vaccines in APAC.
