Shortcuts to create the Covid-19 vaccine will put humanity in danger

NEW DELHI: In the race to win the COVID-19 vaccine race, researchers should not break the defined guidelines and processes involved in vaccine development, as finding shortcuts can do more harm than good in the long run, they warned. Indian health experts on Wednesday.

Almost four decades and 32 million deaths later, the world is still waiting for an HIV vaccine. An effective dengue fever vaccine, which infects about 400,000 people a year according to the World Health Organization (WHO), has eluded scientists for decades.

A clinical trial for an HIV vaccine was suspended earlier this year as the vaccine was not found to prevent infections of the human immunodeficiency virus, the virus that causes AIDS.

Currently, there are more than 100 candidate vaccines at different stages of testing for the SARS CoV-2 virus, but there is always uncertainty with vaccine development.

In the end, the vaccine must be safe for public use and also generate a protective immune response. We are hopeful but there is no guarantee that a vaccine can be successfully developed for every virus. We will have to adapt and live with this new one, said the doctor, Head of Clinical Microbiologists and Infection Prevention, Manipal Hospital, New Delhi.

We continue to hear about sporadic claims from various countries about a successful new vaccine candidate, a drug combo that works in critically ill patients, or old vaccines that are useful, but nothing has yet been massively tested.

The destination still seems to be far away. The reason is that the vaccine must be safe and effective. The regulatory pathway for making the vaccine available is therefore slow, deliberate, thoughtful, data-rich. Informed and peer reviewed, said Dr., MD, senior director of hospital laboratory services at BLK Super Specialty Hospital.

Shortcuts can lead humanity to greater problems.

Furthermore, there is a possibility that we may have to return to a new normal without the availability of a vaccine. And, perhaps, 'collective immunity' will eventually help, Handoo told IANS.

Herd immunity is a form of indirect protection against infectious diseases that occurs when a large percentage of a population has become immune to an infection, either through previous infections or vaccination, thus providing a measure of protection for people who they are not immune.

According to the doctor, director and head of the Department of Critical Care Medicine at Fortis Escorts Hospital, Faridabad, scientific facts are still emerging and we are not quite sure whether the herd's immunity will have an impact or not.

There are reports of recovered patients being reinfected with SARS CoV2. We still have to answer whether natural infection with the virus provides full protection against reinfection or not, Ghosh told IANS.

It is time for us to accept coronavirus as the new normal and start living with it.

We must take precautions against the possible spread of the disease. Today it is coronavirus, tomorrow it may be something else, some of them may be genetically modified. Life must go on, Ghosh added.

Virus testing and contact tracing will be part of our lives in the short term, the experts noted.
