Vaccines and therapeutics that are plant-based for COVID-19 and beyond

Vaccines and therapeutics that are plant-based for COVID-19 and beyond ...

Traditional vaccinations may be extremely costly and in short supply, according to Dr. Hefferon.

Plant-based vaccinations do not require needles, syringes, or special training for their administration. Quite often, they may be stored ambiently, reducing the need for expensive cold storage systems. As such, they may assist in removing key issues related to large-scale vaccination programs in developing countries.

Hefferon demonstrated how plants can be used to improve the availability of inexpensive drugs to even the most remote areas. With only 6.7 percent of people in low-income countries receiving at least their first dose of a COVID-19 vaccination (as of February 2022), initiating vaccination deployment to remote areas is crucial.

The SARS-CoV-2 spike protein is the major antigen capable of producing a robust immune response against the virus.1 The team modified the spike protein to ensure its stability when expressed in plants and to enable it to be purified. We have added a KDEL motif, which is an endoplasmic reticulum retainer.

A geminivirus, which is used to infect plants, and causes the transient expression of the spike protein open reading frame, was then inserted into the spike protein loop.

The spike protein produced by the plants may be used to create a cheap vaccination for individuals around the world.

Two biopharma companies have entered plant-based COVID-19 vaccinations into clinical trials at the time of writing.

The majority of Ebola virus outbreaks and cases have occurred in Africa. Inmazeb and Ebanga are two monoclonal antibodies that simultaneously link to the virus glycoprotein. A vaccination that protects against the most deadly species of ebolavirus has been approved in the United States.

The Middle East respiratory syndrome (MERS) is caused by a coronavirus infection and was first discovered in Saudi Arabia in 2012. Since then, cases have been reported in 27 countries across the Arabian Peninsula.2 The largest outbreak outside the Peninsula, in the Republic of Korea, in 2015. MERS is through close contact with an infected person. There are currently no specific therapies for MERS, and vaccinations are in clinical trials.

COVID-19 is a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first cases of COVID-19 were reported in China in 2019 and the virus has since spread worldwide. Numerous vaccinations have been developed and administered, with the WHO emphasising the importance of vaccine equity.
