Advances in the development of the Universal Code 19 vaccine

There are currently many vaccines available around the world to prevent code 19, but the effectiveness of each vaccine decreases in a few weeks or months.

For example, two doses of Code 19 vaccine developed by Pfizer / BioNtech provide up to 85% protection against alpha and delta corona viruses, but this vaccine has been found to be only 65% ​​effective against omecron.

Researchers are working to develop a Global Code 19 vaccine to address the ineffectiveness of Code 19.

Pfizer and biotech experts recently announced the launch of a global clinical trial for the codex vaccine in the second half of 2022.

Universal vaccines

Universal vaccines provide powerful protection against multiple strains of a virus.

Vaccines currently available against the new strain of coronavirus are declining in effectiveness, but a universal vaccine will be effective against multiple strains and will not require a booster each year.

Dr. Jared Musa, a professor at the Center for Vaccines and Immunology at the University of Georgia in the United States, said that a universal code vaccine could provide better protection against new strains of the code in the future, as well as a vaccine-like ability to prevent its spread.  Can provide  Of the virus.  she is.

How much better would the universal vaccine be than the vaccines currently available?  "It's hard to say right now," said Dr. Dana Hawkinson of the University of Kansas.  He said that it would depend on various factors.

The success of a new or future vaccine will depend on how long it lasts, and how low the risk of serious complications and hospitalization is, he said.

He added that a universal vaccine could only be considered successful if it could prevent the transmission of corona virus from animals to humans.

Technologies

A statement from Pfizer and Biotech said that their universal vaccine would increase the potency of T cells, which would provide protection against a variety of viruses.

Experts say it is difficult to say at this time, but RNA and DNA technology as well as other molecular techniques can be used.

Basic challenges

Developing a universal vaccine will face various challenges.

According to experts, the biggest challenge will be how to be effective against viruses that are constantly evolving.

He noted that "protection from viruses, especially viruses that are new to humans, such as corona viruses, which are constantly improving their ability to spread in humans by modifying themselves, is a major challenge."  But the epidemic must be stopped. "

"The corona virus has a strong ability to transform itself and take advantage of a weakened human immune system, which is a big challenge," he said.
