The power of the COVID vaccine can diminish within a year

March 31, 2021-Two-thirds of infectious disease scientists at major academic institutions say the world needs new or modified ones vaccine New studies show COVID-19 within a year.

In a survey of 77 epidemiologists from 28 countries by the People’s Vaccine Alliance, 66.2% predicted that the world would be within a year before the variants would invalidate the current vaccine. The People’s Vaccine Alliance is a coalition of more than 50 organizations, including the African Alliance, Oxfam, Public Citizen, and the Joint United Nations Program on HIV / AIDS, UNAIDS.

Almost one-third (32.5%) of those surveyed say they will be ineffective within nine months. 18.2% answered that it was within 6 months.

Paul A. Ofit, MD, Director vaccine Philadelphia Children’s Hospital Education Center in Medscape, vaccine It may be ineffective in that time frame. “It’s perfectly reasonable to think that it can happen.”

The good news is that Opfit wasn’t involved in the investigation, this is Coronavirus Mutates slowly compared to other viruses such as: influenza..

“The mutations that have occurred so far are Immunity Prevents protection from at least serious and serious illnesses induced by natural infections or vaccinations. “

That is the goal of the vaccine, he said: “to prevent people from suffering hard.”

Lines may intersect

“And so far, it’s even happening in varieties,” Ofitt said. “That boundary hasn’t been crossed, but I think we should assume that it may intersect.”

Ofit said it would be important to monitor inpatients who were previously infected or known to have been completely vaccinated. Later, he added, countries need to be really good at sequencing these viruses.

The majority of people surveyed (88%) say that persistently low vaccination rates in many countries increase the likelihood of developing vaccine-resistant mutations.

Comparison of coverage between countries is strict.

Many countries do not have one vaccination

Developed countries are vaccinated with COVID-19 vaccine at a rate of 1 person per second, but many of the poorest countries are rarely vaccinated.People’s Vaccine Alliance To tell..

In addition, high- and middle-income countries, which make up one-fifth of the world’s population, purchase about 6 billion doses, according to researchers at Duke University’s Center for Global Health Innovation. However, low- and middle-income countries, which make up four-fifths of the population, buy only about $ 2.6 billion. Nature Report.

“You are only as strong as your weakest country,” Ofitt said. “If we don’t know what’s happening in other countries (affecting the world’s population), we’re not paying attention.”

Dr. Greg Gonzalves, an associate professor of epidemiology at the Yale School of Public Health in New Haven, Connecticut, one of the academic centers surveyed, did not specify when the vaccine would be ineffective, although In a press release The urgency of widespread global vaccination is a reality.

“Unless we vaccinate the world, we leave the competition open to more and more mutations. It’s a booster to avoid our current vaccines and deal with them. It may unleash mutations that may require a shot. “

“Die, but not surprising”

The findings are “disastrous but not surprising,” said Johns Hopkins pulmonologist and MD, MD, Ph.D., who is conducting research focused on healthcare inequality.

Johns Hopkins Medical College in Baltimore, Maryland was also one of the centers surveyed, but Galliazzatos was not personally involved in the survey.

Galiatsatos points out that COVID-19 created a naked gap in who gets the vaccine and who is involved in the trials to develop the vaccine.

“It’s a moral concern and an ethical calculation,” he told Medscape.

He said it was important to recognize the borderless bands that the virus was rigorously destroying.

The United States “must recognize that this cannot be a US-centric issue,” he said. “If we can’t confirm that all countries are doing well, we’ll go back to the beginning. We didn’t see a unified approach at that level.”

He said scientists always knew that the virus would mutate, but now there is competition to find parts of the coronavirus that are less mutated.

“My suspicion is that it’s not a completely different vaccine and will probably require booster immunization,” Galiazzatos said.

Among the strategies sought by the People’s Vaccine Alliance is that all pharmaceutical companies working on the COVID-19 vaccine openly share technology and intellectual property through the World Health Organization’s COVID-19 Technology Access Pool. It may speed up the production and deployment of vaccines to countries.

In the survey, 74% said that open sharing of technology and intellectual property could extend the reach of vaccines worldwide. 23% said it was probably useless, 3% said it was useless.

The survey was conducted from February 17th to March 25th. Respondents include Algeria, Argentina, Australia, Belgium, Bolivia, Canada, Denmark, Ethiopia, France, Guatemala, India, Italy, Kenya, Lebanon, Norway, Philippines, Senegal, Somalia, South Africa, South Sudan, Spain and the United Arab Emirates.
