The president, Joe Biden, assured this Wednesday that if a person is vaccinated, they will not be infected with COVID-19.
"You are not going to get COVID-19 if you have these vaccines," he told a public forum in Ohio hosted by CNN.
This
statement is exaggerated and misleading
.
Although it is very rare, it is possible to get the coronavirus despite being fully vaccinated.
Vaccine efficacy is not absolute, according to their own clinical trials.

In early May, for example, nine New York Yankees players were infected despite receiving the Johnson & Johnson vaccine on April 7.
However, being immunized possibly prevented them from serious health complications from the virus.
"Yes, you can get it by being vaccinated. When you say that a vaccine is 95% effective, what you are saying is that it will be effective 19 to 20 times. That is, 1 out of 20 times we will see a contagion, "epidemiologist Ricardo Castillo, from the University of Pennsylvania, explained to Noticias Telemundo.
Biden also said that a vaccinated person will not end up hospitalized.

But that idea is also exaggerated.
Cases are very rare, but vaccinated people who became ill with COVID-19 and died have been recorded.
The Centers for Disease Control and Prevention (CDC) recognize that, although vaccines are effective in controlling the pandemic, they are not 100% effective in preventing disease from the virus.
“No vaccine is 100% effective in preventing diseases in vaccinated people.
There will be a small percentage of fully vaccinated people who still get sick, are hospitalized or die ”, they explain.

The efficacy of messenger RNA vaccines, such as those from Pfizer and Moderna, in preventing symptomatic disease is 95% and 94% respectively, based on their clinical trials.
In the case of Johnson & Johnson's vaccine, the other licensed in the United States, trials show 72% efficacy, although in Latin America and South Africa the figure was lower (66% and 57% respectively).

"The most exact thing is to say that it is very unlikely that a vaccinated person will get sick with COVID-19," explains Castillo.
The United States had 162 million people fully vaccinated against COVID-19 on July 22.
According to the CDC, as of July 12, 48 states and territories have reported 5,492 confirmed cases of people who received the vaccine and later became infected with COVID-19.
Those cases include 5,189 hospitalizations and 1,063 deaths.
However, the number of vaccinated people who have contracted COVID-19 is almost certainly higher than the official figure, according to the CDC.
"The data may not be complete or representative," the report notes.
They are very rare cases and the vaccine is highly effective
The CDC only collects information from vaccinated people who become infected with COVID-19 and are hospitalized or die.
Until the end of April, they kept track of any case, even the asymptomatic ones.
On April 30, when the United States had vaccinated 101 million people, the CDC recorded just over 10,000 infections among patients who already had the vaccine.
Six out of 10 cases were women.

These cases represent 0.01% of all the people who received the injection and show that getting sick after being vaccinated is extremely rare.
Vaccines have been shown to be effective in preventing illness and death from COVID-19 and slowing the spread of the pandemic, experts say.
"We could have doubts at first, but now we are sure that they are safe. We know that they protect the individual from death, severe illness and hospitalization in almost 100% of cases," explained to Noticias Telemundo the Santiago Neme, an infectious disease specialist and medical director of the University of Washington Medical Center.

"One of the things we observed in the tests with the different vaccines was that the risk of complications, if the disease is contracted, is lower," Dr. Javier Pérez Fernandez, head of intensive care at Baptist Health hospital in Miami, explained to Noticias Telemundo. , Florida.
Even with the Johnson & Johnson vaccine, which is less effective than messenger RNA, experts are optimistic: "It is highly effective in preventing hospitalizations, which is what matters most," explained epidemiologist Ricardo Castillo.

Now, if you have not completed the two-dose vaccination schedule for the Pfizer and Moderna injections, specialists recommend that you do so immediately, as a single dose does not provide enough protection against the delta variant, one more mutation. contagious and aggressive from COVID-19.
“The efficacy of a single dose is low.
If they have received one, they have to wear the second one to have a high protection ”, explained Castillo.
And if you haven't made up your mind to get vaccinated, experts urge you to do so. "With the delta variant and the rapid increases in cases in the United States, an unvaccinated person has a high probability of becoming infected, becoming ill with Covid and ending up in the hospital or worse," Castillo warned.
