Part 2: How COVID-19 mRNA Vaccines Trigger Immunity

In Part 1 of our blog series, we described what an mRNA vaccine is, and how it works.

In Part 2, we will explain how receiving the mRNA COVID-19 vaccine triggers the human immune system to start producing antibodies and facilitates long-term protection.

Part 1: What is an mRNA Vaccine?

Vaccination is one of the most successful public health initiatives in history. Vaccine-preventable diseases are at or near an all-time low. So why are some people so hesitant to receive the COVID-19 vaccine?

It turns out that vaccine hesitancy is as old as vaccination itself. The unknown can be scary, and while modern humans may live in the “Age of Information”, most of us realize that not all information is reliable. Fortunately, help is on the way! In this 2-part blog series, the experts at HemaCare break down precisely what a mRNA vaccine is and how it works to protect those who get it.

COVID-19 Vaccine Series Launch Heralds New Era of Research

The COVID-19 pandemic upended daily lives around the world. Now that we have working vaccines, a new phase has begun in the battle against the deadly virus. Scientists are striving to gather in-depth information about vaccine immune response.

Data collected at the University of Oxford [1] shows that approximately 30.0% of the world population has received at least one COVID-19 vaccine, while just over 15.5% are fully vaccinated. Less developed countries lag far behind more developed nations in their vaccination rates. Only 1.1% of people in low-income countries have received at least one vaccine dose, while the most developed nations are now reaching vaccination rates of 60-70% of their population. [1] And even while countries race to vaccinate as many people against COVID-19 as possible, new strains of the virus are emerging, while vaccine hesitancy slows the global effort to eradicate the disease.

Young Blood's Effect on Alzheimer’s Disease

In Alzheimer's disease, brain cells die, and their connections to one another degenerate leading to decline in mental function. The brain changes that occur in Alzheimer's disease are associated with the production and deposition of beta-amyloid plaques. Currently, treatment of Alzheimer's disease focuses on delaying or slowing mental decline and addressing behavioral complications. There are a few U.S. FDA−approved drugs used to treat Alzheimer's disease symptoms. These drugs regulate neurotransmitters, but have limited duration, only work in some patients, and do not address the underlying cause.

Human Adult Peripheral and Umbilical Cord Blood Platelet-Rich Plasma Have Similar Effects on Skin Healing Processes

Regrowth and healing of skin after severe traumas such as burns and other extensive skin damage are significant medical challenges and depend on complex skin regeneration mechanisms. Skin and other tissue regeneration processes start with platelet degranulation and clotting that are associated with the release of a number of factors including clotting factors and cytokines. Skin tissue regeneration also relies on the action of growth factors. Platelet-rich plasma (PRP) is beneficial for tissue regeneration processes because platelets promote the secretion of growth factors that are essential in wound healing.
