SM-102 is a synthetic amino lipid which is used in combination with other lipids to form lipid nanoparticles. [1] These are used for the delivery of mRNA-based vaccines, [2] [3] [4] and in particular SM-102 forms part of the drug delivery system for the Moderna COVID-19 vaccine.
A molecular clamp is a polypeptide used to maintain the shape of proteins in some experimental vaccines. On a virus, pre-fusion proteins on their surface provide an attractive target for an immune reaction. However, if these proteins are removed or made by recombinant technology, they lose their shape and form what is called a "post-fusion form".
The preparation of ALC-0315 was first described in a patent application to lipid nanoparticles by Acuitas Therapeutics in 2017. [6]: 137 The final step is a reductive amination reaction in which 4-aminobutanol is condensed with a lipid aldehyde, using sodium triacetoxyborohydride as the reducing agent to convert the intermediate imines to the amine of the product.
Anti-vaccine activists Robert F. Kennedy Jr. and Del Bigtree have suggested without evidence that the death of Baseball Hall of Fame member Hank Aaron was caused by receiving the COVID-19 vaccine. Aaron's death was reported as being due to natural causes, and medical officials did not believe the COVID-19 vaccine had any adverse effect on his ...
Myoglobin sketch Alpha helix. 1958 – Myoglobin was the very first crystal structure of a protein molecule. [2] Myoglobin cradles an iron-containing heme group that reversibly binds oxygen for use in powering muscle fibers, and those first crystals were of myoglobin from the sperm whale, whose muscles need copious oxygen storage for deep dives.
A highlight of minutes of the EMA's Pharmacovigilance Risk Assessment Committee (PRAC) concluding 9 April 2021, indicating they also were investigating four cases of unusual blood clots with low blood platelets, including one death, amongst people who had taken the Janssen COVID‑19 vaccine. The Janssen vaccine is approved but not yet deployed ...
On 26 October 2021 The World Health Organization launched a Global Covid-19 Trial termed as the Solidarity Trial Vaccines. Inovio INO-4800 was chosen as the first DNA Vaccine to be introduced in the largest vaccine trial in history. The Countries of Colombia, Mali and the Philippines announced participation with many other countries yet to be ...
Anxiety about COVID-19 makes people more willing to "try anything" that might give them a sense of control of the situation, making them easy targets for scams. [5] Many false claims about measures against COVID-19 have circulated widely on social media, but some have been circulated by text, on YouTube, and even in some mainstream media ...
