The COVID-19 vaccines are now widely available, and vaccinations are progressing across the United States. With over a third of adults vaccinated, there has been a noticeable decline in deaths and hospitalizations among at-risk groups. We are quickly learning the effectiveness of these vaccines.
Despite the growing evidence supporting the vaccines, many individuals who have recovered from COVID-19 remain uncertain about whether they should still get vaccinated. The answer is a resounding yes. Even if you’ve had COVID, vaccination is crucial.
“Getting vaccinated is essential, even if you’ve had COVID-19,” emphasizes Dr. Matthew Goldstein, an infectious disease specialist. Here are some compelling reasons why vaccination is necessary:
Vaccines Provide Stronger Immunity Than Natural Infection
The long-term effects of natural immunity gained from a COVID-19 infection remain unclear due to the virus’s relatively recent emergence. What we do know is that natural immunity can differ significantly from person to person regarding duration and protective capacity. Thus, having had COVID-19 does not ensure immunity.
In contrast, “Research shows that vaccines generate higher antibody levels against SARS-CoV-2 than natural infections,” states Dr. Sarah Becker, a leading researcher in immunology. A study from California revealed that vaccinated individuals had antibody levels up to ten times greater than those who had previously contracted the virus, indicating that even those with past infections can benefit from vaccination.
Vaccination Can Enhance Natural Immunity
Not only does the vaccine likely provide stronger immunity, but it may also enhance your body’s existing natural immunity. Dr. Becker notes, “A single vaccine dose after recovering from COVID-19 can significantly boost your immune response.” The same California study found that individuals with a history of COVID-19 had a more robust immune response after receiving the vaccine.
Vaccines Help Protect Against Variants
While natural immunity may offer some protection against variants, experts believe that vaccines are critical in safeguarding against new strains. Recent studies indicate that a single vaccine dose significantly increases antibody levels, providing better protection against variants like B.1.351.
Vaccination May Alleviate Long COVID Symptoms
Studies estimate that 10 to 30 percent of COVID-19 survivors experience long-term symptoms, known as long COVID. Some patients report symptom relief following vaccination, which leads Dr. Goldstein to recommend that those suffering from long COVID consider getting vaccinated, noting, “It won’t worsen your condition and may help improve it.”
Vaccine-Induced Immunity Can Be Transferred to Infants
Research indicates that pregnant individuals who are vaccinated have a much stronger immune response than those who have had a natural infection. Furthermore, vaccinated mothers can pass protective antibodies to their infants at significantly higher rates compared to those with antibodies from a previous infection.
Vaccines May Reduce Transmission
Scientists are investigating whether vaccinated individuals can still transmit COVID-19. Early evidence suggests that vaccination reduces the likelihood of asymptomatic infections and transmission, making vaccinated individuals about 90 percent less likely to spread the virus.
When Should You Get Vaccinated After Recovering from COVID?
Dr. Goldstein advises getting vaccinated as soon as you finish your quarantine. However, if you received monoclonal antibodies during treatment, you should wait 90 days post-recovery for the vaccine to ensure an effective immune response.
In summary, regardless of whether you’ve previously contracted COVID-19, obtaining the vaccine is vital. Vaccine-induced immunity is typically more robust, and for those with past infections, it serves as an additional layer of protection. This not only safeguards your health but also contributes to the well-being of those around you.
