In terms of design, the vaccine follows a more traditional recipe than the two mRNA-based COVID-19 vaccines or Johnson & Johnson's adenovirus vector-based design. Both of those designs are relatively new and work by delivering genetic code for the SARS-CoV-2 spike protein to our cells, which then translate the code. The Novavax vaccine, on the other hand, is a protein subunit-based vaccine that directly delivers the SARS-CoV-2 spike protein to cells, along with an adjuvant—which is an additive used in vaccines to enhance immune responses to the vaccine. In this case, the adjuvant is derived from saponin compounds found in the Chilean soapbark tree, which have been used in FDA-approved vaccines previously.

Generally, the protein-subunit vaccine design is tried and trusted; it's already used in vaccines against flu, pertussis (whooping cough), and meningococcal infection, for example.

Memes save lives!!!

Pro-vaccination messaging may be surprisingly effective when delivered through humorous internet memes, according to new findings published in the journal Computers in Human Behavior. A series of studies revealed that exposure to sarcastic memes about anti-vaxxers increased UK residents’ intention to receive a COVID-19 vaccine. The researchers suggest that the humorous memes were able to bypass the typical defense processes of people who are vaccine-hesitant.
