Description

There may be some mutually useful lessons to be learned by comparing the vaccine methods and technical platforms utilized for the COVID-19 pandemic to those used for earlier emerging and reemerging infectious illnesses and pandemics. For vaccine developers, regulators, health authorities, and political constituents, the unprecedented scope and speed of the spread of recent emerging infectious diseases provide significant problems. The production and delivery of vaccines are complicated and difficult. The clinical development to emergency use authorization and license, pharmacovigilance of vaccination safety, and tracking of virus variations are all crucial in addition to speed. In low- and middle-income nations, immunization and vaccine access must be given top priority. The sum of these elements will have a significant impact on the final outcome of attempts to stop the current and any upcoming pandemics of infectious diseases.

Infectious viral infections have historically endangered humanity with new outbreaks and resurgences. The emergence and spread of animal viruses as existential threats to humans have been accelerated by a number of interrelated and synergistic factors, including demographic trends and high-density urbanization, modernization that favours high mobility of people by all modes of transportation, large gatherings, altered human behaviours, environmental changes with modified ecosystems, and insufficient global public health mechanisms. The world's population was expected to be 1.8 billion people in 1918, the year of the "Spanish flu." The population is expected to grow by more than 25% from its current 2020 level of 7.8 billion people to 9.9 billion people by 2050. With a high fatality rate in the elderly and those with accompanying comorbidities, the novel Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV- 2) that caused the Cronavirus Disease 2019 (COVID-19) pandemic devoured the entire planet in less than 6 months. The global economy has been badly impacted by the outbreak. The only means of control, short of lockdowns, have been a succession of imperfect and constricting mitigating actions like self-distance, mask wear, travel restrictions, and avoiding gatherings. It appears that the addition of vaccine(s) to current countermeasures works the best now that there have been more than 2 million fatalities and more than 100 million persons are sick.

Together, these factors require researchers and decision-makers to exercise caution, reevaluate the strategy for monitoring and managing dangers from new infectious diseases, and review international controls for pandemic disease.

Long before the identification of infectious agents that cause disease, the emergence of novel infectious diseases has been acknowledged. Human health and international stability are at risk from Emerging Infectious Diseases (EIDs). A historical overview of emerging pandemic diseases provides insight into the origins and traits of coronavirus epidemics, with a focus on the SARS-CoV-2 pandemic. . There are countless opportunities for infectious agents to appear in the ecological niches we are creating as human societies expand in size and complexity. Although the principles are simple, the manufacturing equation is intricate and prone to delays, making it impossible to produce and distribute hundreds of millions of doses of COVID-19 vaccine within a year of the pandemic pathogen's discovery. For regulators and the WHO, it is crucial to take into account the technical platform used to create a vaccine (mRNA, whole inactivated virus, vector, protein with or without adjuvant), the dosage (low, mid, high), the schedule of vaccination (single or two doses), as well as the manufacturer's capability, capacity, and reputation. An important early regulator of vaccination access will be the scale-up phase of manufacturing. Both vaccine nationalism and the recently disclosed bilateral agreements between producers and high-income nations may have an impact on this. Despite having enormous manufacturing capacity, businesses like Sinopharm, the Serum Institute of India, or Bharat must feed the enormous markets of China and India. A number of western and Chinese COVID-19 vaccines have already experienced production delays.

Conclusion

Future vaccines against newly emerging infectious illnesses and novel pandemic pathogens must be developed using the lessons learned from the COVID-19 pandemic. In order to successfully conduct all cross-cutting activities between epidemiologists, scientists, developers, human and veterinary health authorities, regulators, and funders, it is imperative that there be constant vigilance, surveillance, and readiness for the development and deployment of vaccines. Stakeholders in global health have discovered something about effectively creating vaccines: they still have much to learn about creating and using them with adequate consideration for fairness and access.
