Four Approaches to Making Vaccines

PnuVax is a Canadian biopharma corporation dedicated to the development of vaccines and the promotion of better public health practices around the world. With a team that has over 30 years of experience, PnuVax focuses on the research and manufacture of vaccines for diseases such as yellow fever and pneumonia.

The development of vaccines can take many forms. In essence, a vaccine provides active acquired immunity to the recipient against specific infections, but there are several ways this can be achieved.

One of the ways is to weaken germs to the point that it’s nearly impossible for them to reproduce. These weakened germs induce memory B cells in humans which protect us from the same infection in the future.

Another approach is to completely neutralize the germs, effectively killing them. When introduced into the body, even though the germs are inactive, our bodies still recognize them as such and learn to defend against them.

A third method is to only use the parts of a virus that are active in teaching our body to defend against it. This method is only effective against those viruses that elicit an immune response through specific proteins.

Finally, bacteria can be vaccinated against in the same way. By using a neutralized bacterial toxin or the polysaccharide coating of a bacterium, we can become effectively immunized without ever having been infected.
