COVID 2019! Vaccinate everybody by 2021, say experts
Population genetic analyses of SARS-CoV-2 genomes have indicated that these viruses evolved into two major types (designated L and S), which show nearly complete linkage across the viral strains sequenced till date.
But with mutations, there are other strains of this virus, which may have different virulence. Therefore, it is essential to vaccinate everybody by 2021 before the virus acquires any significant mutation, say experts.
Speaking to IANS, Neha Gupta, consultant, Department of Infectious Disease, Fortis Memorial Research Institute, Gurugram, said that through genomic sequencing of the virus, the researchers have found that Covid-19 is mutating, but most mutations are silent mutations, and very slowly accumulating.
“This looks like good news for the success of vaccine. So, if we can vaccinate everyone by early 2021, it can build up protective immunity for a couple of years before the virus acquires another significant novel mutation,” Gupta said.
Citing US health advisor Anthony Fauci, she said the vaccine may be available by September 2020, but the accessibility to the vaccine may be an issue.
“We know about L&S strains of novel coronavirus. But, now we know that with mutations, there are various other strains, which have different virulence,” added Gupta.
Coronaviruses have been causing problems for a long time and their several versions have been known to trigger common colds. Recently, two types have set off outbreaks of deadly illness: Severe acute respiratory syndrome (Sars) and Middle East respiratory syndrome (Mers).
But, their impact has been placid compared to the menace let loose by the SARS-CoV-2, which led to the Covid-19 pandemic.
Responding to a query on how long the protection will last, Neha Rastogi Panda, Senior Resident, Infectious Disease, Department of Medicine & Microbiology, AIIMS, said that it is another big unknown.
“The recent comments published in the Lancet Journals state that the best estimate comes from the closely related coronaviruses and suggests that, in people who had an antibody response, immunity might wane, but it is detectable beyond one year. Immunity against Mers coronavirus, however, can be detectable for four years,” said Rastogi.
She added that human interventions play an important role to select out strains. It can probably become less aggressive (S-type) over the period of time. However, considering the novelty of this virus and the rate of mutations, it is still unknown and unpredictable.
Citing the study, ”On the origin and continuing evolution of SARS-CoV-2”, published in the National Science Review (Oxford Academic), Panda added that the more aggressive L type of coronavirus was found more in the early stages of Wuhan outbreak, but its frequency decreased due to human intervention.
“The L type might be more aggressive and spread more quickly. On the other hand, the S type, which is evolutionarily older and less aggressive, might have increased in relative frequency due to relatively weaker selective pressure,” added Panda
Lucknow: Vishal Singh, a renowned social worker from Lucknow, also known as Foodman, has once again made India proud. He was honored by the Happy Hands Gloves Cooperative Limited Company in Korathai, Thailand, for his work with the Hunger Free World Mission.
The Hunger Free World Mission’s meeting was held in Korathai, Thailand, under Vishal Singh’s leadership. Representatives from several countries, including Mr. Raja Dwivedi (Managing Director of Happy Hands Gloves Limited), Thailand Coordinator Mr. Raja Mishra, and member Mr. Varun Singh, attended the event.
Under Vishal Singh’s leadership, the attendees took a pledge to work together toward creating a hunger-free world.
Speaking on the occasion, Vishal Singh explained that the main goal of the Hunger Free World Mission is social participation. He said the mission is not just about feeding people but also about meeting other basic needs of those who are struggling. The mission focuses on helping families of terminally ill patients in hospitals by providing food and shelter. It also works to fulfill essential needs like education, jobs, and care for the elderly.
For the last 16 years, the Vijay Sri Foundation has been providing free services, benefiting thousands of people. Vishal Singh highlighted that the mission aims to gain global recognition like other organizations such as WHO, WWF, and Red Cross, which work for social causes.
During this meeting, Vishal Singh was appointed as the Chairman of the Hunger Free World Mission by representatives from various countries. They also discussed holding regular meetings in different countries to push the mission forward.
Business tycoon Dr. Abhishek Verma has also supported this humanitarian mission, vowing to promote the idea of “Seva Parmo Dharma” (Service is the highest duty) worldwide. Vishal Singh praised him, stating that people like Dr .Abhishek Verma inspire others to work for the betterment of society.
Recently, Romania’s Ambassador, Mr . Daniela Sezonov Ţane, invited Vishal Singh to the Romanian Embassy in Delhi, where they discussed the mission in detail. Impressed by his humanitarian work, she honored Vishal Singh and invited him to Romania to take the mission forward .

During the COVID-19 pandemic, Vishal Singh and his team worked tirelessly to provide food and help to the needy, including starving children, elderly citizens, and pregnant women. Despite contracting the virus himself, he continued to assist others after his recovery. He even created a life-saving oxygen regulator using household items, which was praised by doctors both in India and abroad.
In his address at the meeting, Vishal Singh spoke about his mission to create a hunger-free world. He pointed out that India’s large population, along with issues like unemployment and poverty, has caused the country to fall on the Hunger Index.
