Japanese Researchers Are Working On Covid-19 Vaccines That Provide Lifetime Protection

NewsJapanese Researchers Are Working On Covid-19 Vaccines That Provide Lifetime Protection

Covid-19 had been around for 2 years now and while we had developed vaccines that can greatly reduce infections and hospitalisation, the protection the vaccine provides does not last forever.

This is also the reason why we need regular booster shots and the Health Ministry in our country had already mulling on a fourth dose for better efficacy.

Meanwhile, researchers at the Tokyo Metropolitan Institute of Medical Science are developing something that might do away with the need for an annual Covid-19 jab and it would be the “dream” vaccine that offers lifetime protection.

According to The Japan Times, emeritus investigator at the Tokyo institution, Michinori Kohara, who had been working for over 3 decades on the vaccinia virus used in the smallpox vaccine, is attempting to develop a Covid-19 vaccine based on the smallpox vaccine.

The smallpox vaccine, developed in 1796, remains the only vaccine that has successfully eradicated an infectious disease, with the last known case being a patient in Somalia in 1977.

Kohara has been working with the National Institute of Infectious Diseases since April 2020 to develop a recombinant vaccinia virus containing the spike protein of the SARS-CoV-2 virus, which he says can produce potent neutralising antibodies within a week of inoculation.

It was found that it is able to retain its efficacy for more than 20 months with just one shot!

Meanwhile, Japanese drugmaker Nobelpharma Co. is planning to conduct their first and second phases of clinical trials of Kohara’s vaccine in Japan within the first half of 2023.

If these trials are a success, the final phase clinical trial will start immediately and will be commercialised by 2024 at the earliest.

The creation of such vaccines could lead to huge financial savings globally and it gives the world an upper hand against the coronavirus, which has infected more than 270 million people and claimed more than 5 million lives around the world.
