Understanding COVID-19 Booster Shots: What You Need to Know
Written on
Chapter 1: The Booster Shot Authorization
Recently, the Food and Drug Administration (FDA) granted approval for a third mRNA vaccine booster for individuals with compromised immune systems. These individuals have immune systems that are weakened due to health conditions or medications they are taking.
The following day, the Centers for Disease Control and Prevention (CDC) supported this decision, advising specific groups of immune-compromised people to receive the booster. However, many people outside these groups are asking, "Should I get one too?" Based on prior discussions about booster shots, the answer remains largely: "No." Let's delve deeper into this topic.
For a comprehensive analysis, I recommend checking out my detailed article on National Geographic. If you're not a subscriber, simply enter any email to access the full article, which will be updated with new insights from the CDC meeting. This discussion will focus on a straightforward Q&A format concerning who should and shouldn't get the booster, along with the reasons behind these recommendations.

Section 1.1: Why Two Doses May Not Be Enough
Certain immune-compromised individuals may not achieve adequate protection after two doses of the Pfizer or Moderna vaccines. For instance, studies show that only about 50% of organ transplant recipients develop any antibodies after complete vaccination. This situation arises because these patients take immunosuppressive drugs to prevent organ rejection.
These medications inhibit the immune response, while vaccines are intended to stimulate it. A suppressed immune system may not respond effectively to vaccination. Similarly, individuals with autoimmune diseases—where the immune system attacks the body—might face similar challenges. Conditions that inherently weaken the immune system, such as blood cancers, can also lead to suboptimal vaccine responses.
Subsection 1.1.1: The Role of a Third Dose
Research has been conducted to determine whether a third dose of an mRNA vaccine can enhance the immune response in those who did not respond well to the first two doses. While some studies indicate that a third dose can trigger antibody production in some patients, others show minimal response. Nevertheless, sufficient evidence now supports the safety and effectiveness of a third dose for many immune-compromised individuals.
Section 1.2: Guidance for Other Vaccine Recipients
For those who received only one dose of the Johnson & Johnson vaccine, it is advisable to get a dose of an mRNA vaccine.
Chapter 2: Identifying Candidates for the Booster
To ascertain if you qualify for a booster shot, the CDC has outlined several immune-compromising conditions:
- Individuals currently or recently undergoing cancer treatment
- Recipients of organ or blood transplants
- Those with severe primary immunodeficiency disorders
- Individuals with uncontrolled HIV or AIDS
- Patients taking specific immune-suppressing medications
- People with chronic medical conditions affecting immunity

Should Antibody Testing Precede a Booster?
The FDA and CDC currently do not recommend antibody testing to determine vaccine response. Instead, they advise eligible individuals to proceed directly to receiving the booster. Some healthcare professionals argue for antibody testing, but the decision ultimately lies between the patient and their healthcare provider.
Booster Eligibility for Teenagers
Individuals aged 12 and older who fall within the aforementioned categories are eligible for the booster.
Proving Need for a Booster
No additional documentation is required to receive a booster dose; individuals can schedule appointments just as they did for their initial vaccinations.
Timing for the Booster Shot
The third dose should be administered at least 28 days after the second dose. If a new immunosuppressive medication is on the horizon, it’s best to get the booster two weeks prior.
Brand Consistency in Vaccines
The CDC recommends receiving the same brand for the booster. However, if the original brand is unavailable, it is acceptable to receive a dose from a different mRNA vaccine.
Final Thoughts on the Johnson & Johnson Vaccine
Most immune-compromised individuals had already received mRNA vaccines before the J&J vaccine was available. For those who received J&J, consulting with a healthcare provider is advisable, as they will likely recommend an mRNA vaccine instead of additional J&J doses.
The Current State of Third Doses
Approximately 1.1 million people have already received one or more additional doses of a COVID-19 vaccine. Many of these individuals, particularly those working in public-facing roles, felt compelled to seek extra protection due to their circumstances.
Should Everyone Get a Booster?
The short answer is no, unless you are in a high-risk group. Individuals with a functioning immune system who received two doses of Pfizer or Moderna do not need a third shot at this time.
The Delta Variant and Breakthrough Infections
While the Delta variant has led to an increase in breakthrough infections, this is not indicative of vaccine failure. The vaccines still provide substantial protection, and breakthrough cases often resolve swiftly.
Addressing Concerns About Vaccine Availability
If you still wish to pursue a third dose, it’s important to understand that resources should be prioritized for those who have yet to be vaccinated or are hesitant. The global pandemic requires a focus on vaccinating populations who lack access.
Expert Opinions on Third Doses
Renowned rheumatologist Alfred Kim emphasizes that a third dose may not significantly enhance protection for most individuals. Instead, he advocates for clear communication about current vaccine efficacy and encourages individuals to trust their existing immunity.
Statistical Insight
Approximately 2.7% of U.S. adults, or around nine million people, are immune-compromised. The efficacy of Pfizer and Moderna vaccines in these individuals is notably lower than in the general population.
Update on General Booster Recommendations
Following the publication of this article, Pfizer announced promising data regarding booster efficacy. However, the critical question remains: why prioritize boosters for the U.S. when millions globally still lack vaccination? The emphasis should be on providing vaccines to those in need, ensuring a collective effort toward ending the pandemic.
