Vaccines are very effective in preventing hospitalization and preventing death, and infections are rare among immunizations.
But according to some experts interviewed, not everyone has a one-size-fits-all approach that works. People need to take into account factors such as the rate of transmission in their environment, personal risk levels and their own risk tolerance to help determine what is best for them.
The Centers for Disease Control and Prevention (CDC), America’s leading federal public health agency, dropped advice on vaccinators wearing masks in May.
At the time, the number of Covit-19 cases was in the free fall, and the Biden administration sought to announce a return to default following a vaccination campaign.
But on Thursday, more than 50,000 cases were identified in the country. An uprising mainly caused by delta variability, and is often concentrated in areas with very low vaccination rates.
It should be noted, however, that the increase in cases did not translate into a proportional increase in hospital admissions and deaths.
About 200 daily deaths are set to be reduced, a figure much lower than the 3,500 recorded each day during the height of the winter tide.
More than 97% of those admitted to the hospital reported last week, CDC director Rochelle Valensky said last week, while the death toll was 99.5%, the doctor said last weekend. -Vivek Murthy, President of the United States.
Rochelle Valensky defended the CDC’s position on mask wear on Thursday, stressing that the company has always said that individuals should take local conditions into account.
“If you are in an area with a high case rate and a low vaccination rate, where delta variant cases are on the rise you should definitely wear a mask if you are not vaccinated.”, She insisted.
“If you are vaccinated, you will receive exceptional protection from the vaccine. But you are free to decide whether to add additional protective layers.”, He added.
Joseph Allen, an associate professor at the Harvard School of Public Health, supports the CDC’s position.
“I do not think we are at a point in the United States and the most vaccinated countries. This recommendation (to wear a mask) still makes sense to everyone.”, He says.
From “frustrated” back and forth
If the World Health Organization had insisted that fully vaccinated people continue to wear masks, this is especially in light of the overall situation, with only 13.4% of the world’s population being vaccinated.
“For me, the goal with all vaccines has always been to prevent serious cases and deaths, and that’s what they do best.”, Joseph Allen insisted.
A recent study in prisons on infectious diseases found 27 positive cases in a population of 2,380 people vaccinated: 1.1% developed Covit-19, and all were asymptomatic, their case was found during routine testing.
However, as the vulnerability of the virus in an environment is high, the incidence of cases among vaccinators is high.
Celine Counter, an epidemiologist and epidemiologist, compares the situation before the onset of the delta variation to driving around her surroundings, while the current situation is similar to driving to a racing round.
“When driving around you, the seat belt is enough”, He said, the seat belt that marks the vaccine.
“But if you’re in the racing circuit, these drivers will have helmets and airbags, except for the seat belt.”, Masks representing additional protective layers, he added.
In some places in the United States, such as Los Angeles or Philadelphia, local authorities have re-established the obligation to wear masks indoors.
U.C. To Dr. Monica Gandhi, a physician specializing in infectious diseases in San Francisco, The “People are so frustrated back and forth”. He therefore recommends setting statistical markers to link, for example, the obligation to wear a mask for hospital admission rates. Monica Gandhi, like other experts, proposes the number of people admitted to more than five hospitals per 100,000 citizens as a gateway to resumption of normal activities
Monica Gandhi, Joseph Allen and others argue that these are “Exit curves” Can be used in schools when it reopens in the fall, while the American Academy of Pediatrics supports universal masked clothing, even among vaccinated teachers and students.
