The vaccine market plays a crucial role in global public health through preventing infectious diseases and protecting communities. In this contemporary world, vaccination is one of the most effective public health strategies through various vaccines that are recommended, sometimes mandatorily by different regions. From birth, most children are vaccinated with essential vaccines including those for hepatitis B, diphtheria, tetanus, pertussis sometimes called whooping cough, polio, Haemophilus influenzae type b (Hib), pneumococcal disease, measles, mumps, and rubella (MMR). These vaccines prevent the deadliest diseases and form the backbone of national immunization programs in countries like the United States, Canada, Australia, and most of Europe.
