Here is why a coronavirus vaccine will not be enough
Almost all vaccine candidates tested should require two doses, say experts.
With new information that continues to exit concerning progress in the development and distribution of efficiencycoronavirus vaccine, health professionals are learning more and more about what the end result could look like. More recently, several experts of this type speakingUnited States today revealed that if and when a successful vaccine is developedIt will probably require two shotsAnd probably a booster on the road.
"As far as I know, with a set of exceptions, all front-line vaccine developers contemplate two shots"Booby, Doctorate, Immunologist and Public Health Professor at Harvard T.H. Chan School of Public Health, told the newspaper. "The only exception is Merck, who pushed last week on two vaccines, each of which they hoped to be unique vaccines."
Although it is too early to say about it at this stage, themedical community Will have a much better idea of whether a two-stage plan will be needed on the basis of human test results, which in some casesshould start in July, according to a recent interview thatAnthony Fauci, MD, did with theAMERICAN MEDICAL ASSOCIATION JOURNAL.
The reason the administration of two doses could be necessary will be based on how the immune system reacts at the initial dose,L.J. Tan, Strategy Manager with the Coalition of Immunization Action and Co-Chair of the National Adult Vaccination Summit and the AntiGripal Vaccination Summit, explained toUnited States today.
"The immune system examines and trafficks and remembers, developing antibodies and immune cells," said Tan. "If an infection comes at this point, you will fight it and you will not fall sick - you will be immune."
However, with some viruses - especially those that your body has never been exposed before, such as coronavirus, a second shot is necessary to armyour immune system With the power to completely struggle infection. Essentially, the first shot presents the virus to your immune system, while the second reinforces its ability to properly defend against the pathogen. If this turns to be the necessary action plan with a coronavirus vaccine, TAN said the two shots will probably be administered about one month or two, although it is not definitive.
On the basis of recent comments, Fauci expressed its concern that a vaccine is not likely to provide long-term immunity, it is also quite possible that in addition to the two initial doses, a recurrent shot. Maybe need to maintain immunity.
Although none of this is rare, because vaccines often have to be administered in this way, it poses potential logistical headache for the country's health system if it needs to plan and administer double doses of the vaccine. Millions of people in a finished window of time. . For now, we will have to wait and see. And for more developments on Covid-19 immunity,That could last the coronavirus vaccine, tell doctors.
