At present, it is clear that Covid-19 vaccines currently used are very efficient to protect against the virus. In fact, a recent study published by disease control and prevention centers (CDC) revealed that Moderna and Pfizer are 90% effective in real conditions. But according to a recent survey on scientists, help can be short-lived, like the world canNeed new Covid vaccines in less than a year. Read it to see when the scientific community thinks the time will be executed on these versions of the vaccine and for more information on what you should do as soon as you get your shots, checkThe first thing you need to do after you are fully vaccinated, say experts.

The serious forecasts come from the results of a recent survey conducted by the popular combination of alliance, a coalition of international organizations that includes Amnesty International, UNAIDS and Oxfam.

77 epidemiologists, virologists and specialists of infectious diseases from 28 responding countries, two-thirds felt that current first generation vaccinesshould be modified to stay effective in a year,The Guardian reports. The remaining third of respondents had an even stricter perspective, providing that changes may be necessary now nine months.

But the investigation also broke out why they believedCurrent vaccines could soon be obsolete. 88% of respondents reported that low vaccine coverage in some countries would create the possibility that new variants appear to make current clichés much less effective.

"New mutations arise every day. Sometimes they find a niche that makes them better than their predecessors. These lucky variants could transmit more efficiently and potentially escape immune responses to previous strains",Gregg Gonsalves, PhD, Associate Professor of Epidemiology at the University of Yale, said in a declaration. "Unless we vaccinate the world, we leave the playground open to more and more mutations, which could eliminate variants that might escape our current vaccines and require punches to treat them." And for more what could already affect how your doses protect you, checkThe vaccine against Pfizer can be less effective if you have this common condition.

The survey also found that nearly three-quarters of respondents felt that the open sharing of technology and intellectual property between countries couldconsiderably improve the deployment of the vaccine. In the meantime, programs such as the World Health Organization COVAX (WHO) initiative to create a stock of international origin to ensure an equal distribution of doses between the richest and poorest nations. But some policy experts believe that the program is much too low to be effective in preventing the propagation of COVID.

"The urgency we see in the rich nations to vaccinate their populations, aimAll adults of summer, is simply not reflected globally. Instead, we have COVAX 'worthbooks for maybe 27% [of the low-income country population] by the end of the year if we can possibly manage it, which is simply not good enough, "Max Lawson, head of the inequality policy in Oxfam and the President of the Vaccination of the Alliance People, said inThe Guardian.

Survey results put more feedback from otherTop Experts of the Pharmaceutical Industry. According to the CEO of ModernaStéphane Bantel, we are probably goingNeed to get a Covid vaccine booster every year, potentially combined with other annual shots.

"You could find yourself with a thing like the flu where every year, every two years, you need a boost," said BantelStrong. And well ahead of the window expected of nine months until it can become less effective, he also said that Moderna had already submitted a new version of the vaccine focusing on the South African variant B.1.351 to the institutes National health for testing and yet another version that can be stored at the standard refrigerator temperature has already started clinical trials.
