Under detection and underreporting are problematic for a variety of reasons. They make it more difficult to understand the true spread of the virus, which impacts everything from resource planning in healthcare systems to public policies designed to reduce infection spread.
Releasing a vaccine to the public where it can make a positive impact on public health and individual lives is a complex process. Quality control testing is critical at every stage, from initial development to full-scale production, to make sure vaccines are as safe as possible.
As infectious diseases evolve, the medical community has been working to meet the challenge by updating and improving the tools we use to combat infections. Right now, biopharmaceutical research companies have 421 medicines and vaccines in development to treat or prevent fungal, bacterial, and viral infections.
