MIT University, led by an Iranian researcher, schedules vaccine doses



Most vaccines, from corona to measles, require several nv injections of different doses to fully immunize a person. To make this task easier, the researchers of the world’s top university, namely (Massachusetts Institute of Technology) MIT In the state of Massachusetts, led by Morteza Sarmadiresearch specialist and degree holder PhD From this university, they have cultivated microparticles with an interesting feature.

These researchers have invented microparticles that can keep the contents inside like a package under the skin until the right time to release it. Using this feature, multiple doses of vaccine can be administered in one injection and timed. This team of researchers named these types of vaccinesSelf-boosting vaccines” put.

Injection of multiple doses of vaccine with a single injection with the new design of Morteza Sarmadi, MIT researcher
An interesting design of how a self-boosting vaccine works that stores different doses and releases them at certain times.

This vaccine model can be very useful for remote areas where people have less access to medical centers. Because with one visit, people can fully vaccinate themselves or their children.

This feature can be used for any type of vaccine, with any number of doses; including protein vaccines and vaccines based on DNA and RNA. According to the researchers, this procedure could also be used for other treatments, such as cancer drugs, biological drugs or hormone therapy.

The general idea of ​​this project has been proposed and tested since 2017. But in a new study, researchers have figured out exactly how it should be used and found new ways to mass-produce it. The team was quite surprised that the size of the particles had no effect on their release time; Rather, everything depends on the type of polymer they use.

The team observed that the polymer PLGA It is slowly broken down by water, until it finally breaks down and releases its contents into the body. Different combinations of polymers break at different rates. This allows scientists to schedule the release of different doses of the vaccine.

Morteza Sarmadi says in this regard:

If the material inside the particle needs to be released after 6 months, we use a polymer that breaks after 6 months. If we want the vaccine dose material to be released in 2 days, we use another polymer that holds the material for 2 days. So a wide range of applicants can use this research and observations.
