In general, a booster shot is given at some point after the initial vaccination to further strengthen immunity, to reactivate immunity after it has weakened, or to protect against new strains of the virus for which someone has been vaccinated. Depending on the reason for the booster injection to continue to protect against COVID-19, the shot may resemble the vaccine that was given or slightly modified to add specific protection against the mutation of the virus.
Why do you need a COVID-19 booster shot?
It’s not clear if we really need a booster for the COVID-19 vaccine. Hence, the potential timing for them is even less obvious. “A booster will depend on two factors,” says Timothy Brewer, MD, professor of medicine and epidemiology at UCLA. One is whether COVID-19 immunity diminishes over time, he explains. “We know there is, but the question is how much,” said Dr. Brewer. So far, we have found evidence to suggest prolonged immunity the furthest is eight monthsBut we don’t have any data out there yet.

The second variable, or motivation, is viral mutations. Dr. Brewer explains, the reason you get a flu shot every year is not because of your immunity from last year’s flu shot, but because the virus has changed enough so that last year’s shot no longer has full protection. enough from it. Fortunately, he said, the coronavirus doesn’t change as quickly as the flu virus does. Dr. Brewer said: “Although they certainly do change – that’s why we have variations – the question is whether they change fast enough for you to need to supplement, and that is still not clear
The existing variants – namely South Africa variant B.1351, Brazilian variant P.1, and two California variants B.1.427 and B.1.429 – make current vaccines somewhat less effective, to varying degrees. So while the available vaccines still prevent serious illness, hospitalization and death in people infected with these strains, they do not necessarily protect well against these infections, in a way. completely. “Ah learn Dr. Brewer said South African variations could occur even in people who have already received the Pfizer vaccine. It is therefore possible – based on these early findings – we will need special boosters to help protect against these strains. But Dr. Brewer says this is still not known for certain.
When do you need to get COVID-19 again
Pharmaceutical companies are actively preparing ramp-ups to roll out in late 2021 or early 2022. Recently, Pfizer’s CEO, Albert Bourla to speak “likely” people will need a booster set within the next 12 months and Moderna has announced that its booster will be ready in the fall. How those boosters will look – how and why they will differ from the initial dose received – remains to be determined as companies test different options and wait for data.
But the decision as to whether the population should be re-vaccinated with a booster shot is not made by pharmaceutical companies, to speak Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases (NIAID) and chief medical advisor to President Joe Biden. Instead, that call will come from the Centers for Disease Control and Prevention (CDC). Dr. Fauci now predicts that experts will know enough by the end of this summer or early fall to make a decision about the need for a boosters.
In short, it’s still not known if you will need a booster, let alone the exact timing of the aforementioned booster. Data is still being collected in real time, as it happened during the pandemic. And while such unknowns can be frustrating or even frightening, keep in mind that if you’ve been vaccinated, you are currently well protected from a serious illness and will likely take long enough to catch. Immunization inquiries were answered.
If we need them, then the relative success of our current vaccination program signals boosters. Last week, Andy Slavitt, a senior adviser to President Biden’s COVID response group, told reporters that the administration was looking into potential demand for boosters in its planning efforts. “Asking for additional photos in the future is clearly a foreseeable potential event,” he said to speak. “I can assure you that when we do our planning, when the president orders to buy more vaccines like he did and when we focus on all the opportunities to expand production. We say here, we are most likely to have scenarios like that rationally. “
