    Indeed, the potential for epochal change may manifest sooner than anticipated, even before Jupiter completes its journey away from the Grand Conjunction. Encouraging developments in the past month have ignited hope for bringing the pandemic under control. A remarkable surge of global collaboration has seen over 90 vaccines in development against SARS-CoV-2, organized by research teams in diverse institutions worldwide. These vaccine candidates employ a diverse array of technologies, including some that have never been utilized in a licensed vaccine. Nature’s graphical guide explains each vaccine design: Virus Vaccines: Numerous research teams are currently engaged in the development of virus-based vaccines, employing either weakened or inactivated forms of the virus. This approach mirrors the methodology used in the creation of many existing vaccines, including those effective against diseases like measles and polio. 

Nucleic acid vaccines represent a novel approach to vaccine development, with approximately 20 research teams currently pursuing this avenue. These vaccines utilize genetic material, either in the form of DNA or RNA, encoding a specific coronavirus protein that triggers an immune response. Upon administration, the nucleic acid is introduced into human cells, where it instructs the cells to produce copies of the virus protein, typically targeting the spike protein of the virus.

While this methodology holds promise, it is important to note that nucleic acid vaccines remain unproven in the context of licensed vaccines, with no currently available vaccines utilizing this technology. Nevertheless, the innovative nature of this approach underscores its potential as a cutting-edge tool in the ongoing fight against the pandemic.

Viral-vector vaccines represent another promising avenue in the quest for a COVID-19 vaccine, with approximately 25 research groups currently dedicated to their development. This approach involves the genetic engineering of a virus, such as measles or adenovirus, to enable it to produce coronavirus proteins within the body. Importantly, these engineered viruses are weakened to ensure they cannot cause disease.

There are two main types of viral-vector vaccines: a) Those that retain the ability to replicate within cells after administration. b) Those that have had key genes disabled, rendering them unable to replicate.

It's noteworthy that no licensed vaccines currently utilize this method for COVID-19. However, viral-vector vaccines have a well-established history in gene therapy, underscoring their potential as a powerful tool in combating the pandemic.

Protein-based vaccines represent a promising avenue in the quest for effective COVID-19 vaccines, with researchers exploring various approaches to elicit an immune response against the virus.

1.   Protein Subunits:

o   This approach involves injecting coronavirus proteins directly into the body or utilizing fragments of proteins or protein shells that mimic the virus's outer coat.

o   Twenty-eight research teams are focusing on vaccines containing viral protein subunits, with particular emphasis on the virus's spike protein or its receptor binding domain.

o   Similar vaccines targeting the spike protein of the SARS virus have shown efficacy in protecting monkeys against infection, although they have yet to be tested in humans.

2.   Virus-Like Particles (VLP):

o   Virus-like particles are empty virus shells that mimic the structure of the coronavirus but lack genetic material, making them non-infectious.

o   Five research teams are developing virus-like particle (VLP) vaccines, which have the potential to induce a robust immune response.

o   However, VLP vaccines can be challenging to manufacture despite their ability to trigger a strong immune response.

Both approaches hold promise in the development of COVID-19 vaccines, with ongoing research aimed at optimizing their efficacy and safety profiles.

Racing Against the Pandemic: The Quest for COVID-19 Vaccines

The race for a viable coronavirus vaccine has reached a pivotal juncture with Pfizer's recent announcement on November 9th.
