New study reveals huge benefit of getting vaccinated after having COVID-19

A new study suggests that the vaccine may provide great benefit to those who have had COVID-19.

Research looked at an incident where the delta variant passed through a Texas prison, infecting three-quarters of those incarcerated there. Almost 80% of those infected were fully vaccinated, most with Pfizer vaccines. But while the new study shows that rupture can absolutely occur in high-risk environments like prisons and prisons – where it is often impossible to maintain physical distance and where good ventilation is a major concern, it does. also contained good news.

First, COVID-19 vaccines have largely prevented serious illness, even in the face of the delta. Four of the 172 people who caught the coronavirus were hospitalized during the outbreak. Three were not vaccinated.

And by far the lowest attack rate was among fully vaccinated people who had also been previously infected with COVID-19 – “underscoring the importance of vaccination, even among people who have already been infected”, argued the authors of the study, published by the Centers for Disease Control and Prevention last week.

One of the limitations of the study is that the pool of people who had been infected with COVID-19 and who had also been vaccinated was relatively small.

Yet research offers more evidence that fully vaccinated people have a high degree of protection against hospitalization or death – even in very high transmission environments and even in the face of the delta variant, which is about twice as contagious. than the previous variants.

And this adds to a growing body of evidence suggesting that people who have had and recovered from COVID-19 – and that have been vaccinated – are probably the safest of all.

Why vaccines are recommended even if you’ve had COVID-19

Some people, like former running mate Sarah Palin, have spoken out against vaccinating infected people, saying “natural” immunity is safer and possibly stronger. They reported on a study in Israel that suggested the strength of natural immunity.

But that study was not peer reviewed, and it was shared widely on social media with parts of its findings omitted, namely that immunity was higher in people who received a dose. Pfizer vaccine.

In fact, the CDC has been saying for months that people who have had COVID-19 and have recovered should still get vaccinated, in part because researchers still don’t know how long natural immunity lasts (although if you have received certain treatments, such as monoclonal antibodies, you must wait three months before getting vaccinated).

Additionally, previous studies have shown that among people who contract COVID-19 and recover, those who do not get vaccinated are more than twice as likely to receive COVID-19 again than those who are fully vaccinated.

It all shows: getting the vaccine is important, even if you’ve had COVID-19 before.

And while the vaccination does a great job of keeping people out of the hospital, it doesn’t completely stop the spread of the virus. Mitigation strategies such as masking, social distancing, hand washing and improving ventilation are still needed to contain the virus, especially in high-risk settings.

Experts are still learning about COVID-19. The information in this story is what was known or available at the time of publication, but directions may change as scientists find out more about the virus.
