Vaccines Global Summit

Influenza and respiratory vaccines are really important tools for preventing any illness that affects the respiratory system, such as the flu, pneumonia, or viral infections in the respiratory system. These vaccines play a very important role not only in reducing spread but also lowering hospitalizations and supporting public health as well during peak flu seasons and outbreaks. An influenza vaccine, also known as the flu shot, is developed annually to confer immunity against the most prevalent strains of the influenza virus. The rapidity with which the influenza virus evolves requires that researchers update the vaccine annually to one that more closely reflects the strain circulating during a specific year.

There are two forms of influenza vaccines— inactivated and live-attenuated. The inactivated flu vaccine has extensive use and can be used safely in most immunocompromised patients, while the live-attenuated nasal spray vaccine would serve as an alternative for healthy people. Such vaccines minimize the symptoms of the disease, reduce the potential complications, and help protect the most vulnerable populations, such as the elderly and young children. In addition to flu, respiratory vaccines prevent other infectious diseases by invading microorganisms attacking the respiratory system, such as pneumococcal infections, which include bacteria that can cause pneumonia, meningitis, and bloodstream infections primarily in infants and the elderly.

Pertussis, or whooping cough, also has vaccines available, which can be formulated with other immunizations to give full protection, and can be administered in combination with other vaccines such as DTaP. For example, universal influenza vaccines intended to protect against a broad range of flu strains with one dose are part of future research in respiratory vaccines. This may potentially mean fewer annual vaccinations and more solid immunity to pandemic flu. Researchers are also exploring ways to make these vaccines more efficacious and accessible by using mRNA and other technologies.

These are vaccines against influenza and respiratory pathogens, for which prevention of infection is still a crucial tool in controlling the spread of infectious diseases affecting the respiratory system. Vaccination against such diseases ensures that persons are protected not only in terms of health but also that healthcare systems are eased as communities stay healthier and more resilient.
