Stanford single-dose nanoparticle vaccine for COVID-19
Researchers at Stanford are working to develop a single-dose vaccine for SARS-CoV-2 that could potentially be stored at room temperature.
Fact check: Lipid nanoparticles in a COVID-19 vaccine are there to transport RNA molecules
Social media users have claimed the presence of lipid nanoparticles in a COVID-19 vaccine means it could contain small robots or computers. This is false - these nanoparticles are tiny lipid droplets that transport and protect the vaccine component.
Nanoparticles May Be the Culprit in Rare COVID Vaccine Allergic Reactions
By Rick Moran Dec 22, 2020
Scientists may be zeroing in on what has caused severe allergic reactions in at least six people who have received a dose of Pfizer’s COVID vaccine. Both the Pfizer and Moderna vaccines contain tiny nanoparticles of PEG — polyethylene glycol. The manmade compound is used as part of the packaging of the messenger RNA. PEG helps carry the vaccine to human cells and also acts as a boost to our immune response
Anderson Explains Role of Nanoparticles in Vaccines
Dr. Dan Anderson
If and when effective vaccines for Covid-19 are developed, some will surely rely on a nanoparticle delivery system whose origins lie in decades of painstaking groundwork.
Offering a tour of that effort on July 15 was Dr. Dan Anderson of MIT, who gave the ninth lecture in NIH’s Covid-19 scientific interest group lecture series.
Single-dose nanoparticle vaccine for COVID-19: What is it and how effective is it against the virus?
Nanoparticle COVID-19 vaccine will balance the effectiveness of viral-based vaccines with the safety and ease-of-production advantages.

COVID-19 vaccine rollout has begun across the world and in many places health care workers and high-risk groups are beginning to receive the shots. This offers hope for a return to normalcy amidst the pandemic. However, the vaccines authorized for emergency use require two doses to be effective, which can create problems with logistics and compliance. Now, researchers from Stanford University have managed to construct and test a promising vaccine candidate for COVID-19. What is unique about this vaccine is that it is a single dose one and it does not require a cold-chain for storage or transport. It is also likely to be a cheaper alternative.

While the first two Covid-19 vaccines relying on messenger RNA technology speed toward regulatory approval in the U.S., it’s worth remembering the vehicle that gets them where they need to go in the body.
Nanoparticle vaccine for COVID-19 spurs robust immune response in preclinical tests
The novel vaccine technology, developed at Scripps Research, uses virus-like protein nanoparticles to elicit high levels of protective antibodies.
September 21, 2020
LA JOLLA, CA—In a new study that demonstrates the promise of a novel vaccine approach for COVID-19, Scripps Research scientist Jiang Zhu, PhD, showed that his protein nanoparticle technology successfully triggered a strong immune response in mice. Zhu, who co-founded the spinoff company Ufovax to commercialize the technology and manufacturing platform, says he hopes to advance the vaccine into clinical trials early next year.
Suspicions Grow That Nanoparticles in Pfizer’s COVID-19 Vaccine Trigger Rare Allergic Reactions
December 22, 2020
Science’s COVID-19 reporting is supported by the Pulitzer Center and the Heising-Simons Foundation.
Severe allergy-like reactions in at least eight people who received the COVID-19 vaccine produced by Pfizer and BioNTech over the past 2 weeks may be due to a compound in the packaging of the messenger RNA (mRNA) that forms the vaccine’s main ingredient, scientists say. A similar mRNA vaccine developed by Moderna, which was authorized for emergency use in the United States on Friday, also contains the compound, polyethylene glycol (PEG).
Scientists develop a 'nanoparticle' COVID-19 vaccine that could trigger a 10-times stronger immune response than the reaction seen in survivors and protect against future mutated strains
- Scientists have developed an experimental vaccine that uses nanoparticles, which mimic the structural features of the coronavirus
- The body is trained to recognize the receptors the virus uses to enter and infect human cells, and builds up antibodies
- In mice, the virus produced ten times more neutralizing antibodies than those seen in COVID-19 survivors
- The jab also produced a strong memory cell response, in which the body remembers the invading virus to produce antibodies if infected in the future
- In one monkey, the vaccine bound to different parts of the vaccine's spike protein, which could protect against future mutated strains
Hazards of the COVID-19 vaccine

The COVID-19 (SARS-Cov-2) vaccine is fraught with hazards. This should be the obvious, rational conclusion of anyone who cares to objectively study the available scientific and other relevant information about it. There are many factual danger signals that are easily discernible.
