Scientist reveals when Covid vaccine with lifelong protection might be available — Analysis

It is based upon well-known technology and produces fewer side effects than other jabs, claims its inventor.

Clinical trials are underway for a Covid-19 vaccine that could provide lifelong protection. It has been tested on primates as well as mice. According to Michinori Kohara, a Japanese scientist, production is scheduled for 2024.

The existing Covid-19 vaccines required booster shots in order to be effective. Therefore, an emeritus investigator from the Tokyo Metropolitan Institute of Medical Science created one using the smallpox vaccine of 18 century, which was credited for eliminating the deadly disease.

Although I’ve worked with many vaccine technologies, including messenger RNA and adenovirus, the vaccine using the vaccinia vector virus is my favorite. It has few side effects.” Kohara said, adding that the vaccine “Can induce antibody production and long-lasting immunity.”

According to the researcher, one shot of a recombinant vaccinia virus containing the spike protein of the SARS-CoV-2 virus remains effective for more than 20 months, and “These effects can only be achieved by no other vaccine.” Two shots taken three weeks apart increase neutralizing antibodies tenfold, he said.

Study reveals Covid vaccine fears of Russians

The vaccine was tested on coronavirus infected macaques and mice with avian flu.

The first phase of clinical trials will begin in 2023, with 150-200 volunteers. Final phase will begin if the Japanese pharmaceutical firm Nobelpharma Co. conducts successful trials. It is expected that mass production of the drug will begin in 2024.

A number of vaccines have been developed in the meantime. Jonathan Heeney, a professor at Cambridge University, announced the trials of an injectable Covid-19 vaccine that is needle-free. He hopes it will offer greater protection against other covid variants.

According to Veronika Skvortsova (head of Russian Federal Medical-Biological Agency), Convasel, a new Russian coronavirus vaccine, will be approved before the close of the first quarter of 2022.

Tedros Adhanom Ghebreyesus of World Health Organization, expressed optimism in Friday’s New Year message that the Covid-19 outbreak might be overcome. He called on all countries to work together to reach the target of vaccinating 70% of the world’s population by the middle of 2022.
