New Covid-19 Vaccines: Expert Advice on Timing Your Shot for Optimal Protection

With the recent approval of updated Covid-19 vaccines by the FDA, there’s a growing discussion about the best time to get vaccinated. As the U.S. faces a surge in infections, many are wondering whether to rush for the new shot or wait a bit longer. The right decision depends on factors like your health, age, recent infection history, and vaccine availability.

Understanding the Updated Vaccines

This week, the FDA greenlit updated vaccines from major pharmaceutical companies like Pfizer and Moderna. These new vaccines are specifically designed to combat the most current strains of the virus, ensuring that individuals receive the most effective protection available. As the virus continues to mutate, staying up-to-date with vaccinations is crucial for reducing the risk of severe illness, hospitalization, or even death.

To Get Vaccinated Now or Later?

The timing of when to get your Covid-19 shot isn’t a one-size-fits-all answer. It depends on various personal factors, according to experts like Dr. Carlos del Rio, a distinguished professor of medicine at Emory University and a leading authority on infectious diseases.

“If you’ve recently had Covid-19, especially within the last three months, you may want to hold off on getting the updated vaccine,” Dr. del Rio advises. This is because recent infection can provide a temporary immunity boost, which might make getting a vaccine less urgent for the time being.

On the other hand, Dr. del Rio recommends that individuals who haven’t had a recent infection, especially those aged 65 and older or with underlying health conditions, should consider getting vaccinated as soon as possible. “The risk of severe outcomes from Covid-19 is significantly higher in older adults and those with compromised immune systems,” he notes.

High-Risk Groups: Who Should Prioritize the Vaccine?

Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia and a member of the FDA’s vaccine advisory committee, highlights four key groups at higher risk of severe Covid-19 complications:

1. Immunocompromised Individuals: Those with weakened immune systems, either due to medical conditions or treatments like chemotherapy, are at heightened risk.
2. People with Chronic Health Conditions: This includes individuals with obesity, diabetes, chronic liver, lung, or heart diseases.
3. Pregnant Individuals: Pregnancy can alter immune function, making pregnant people more susceptible to severe illness.
4. The Elderly: Specifically, those aged 75 and older, who are more vulnerable to severe outcomes from Covid-19.

For these groups, getting the updated vaccine as soon as possible is strongly recommended.

Should Younger, Healthier Adults Wait?

Experts suggest that younger, healthier adults might benefit from waiting a bit longer before getting the new vaccine. Dr. Offit explains that the immunity boost provided by the vaccine tends to wane after a few months, so timing the shot to coincide with the peak of respiratory virus season—typically in December and January—might offer better protection.

Dr. Megan Ranney, dean of the Yale School of Public Health, agrees. “If you’re not in a high-risk category and haven’t been recently infected, you might consider waiting until fall to get the new booster,” she says. Dr. Ranney herself plans to get her Covid-19 booster around the same time as her flu shot in October.

Vaccine Options: mRNA vs. Protein-Based

The updated vaccines from Pfizer and Moderna, both mRNA vaccines, are expected to be available first. However, Novavax’s protein-based vaccine will likely be released in the following weeks. Dr. Ranney notes that individuals who are hesitant about mRNA vaccines, despite their proven safety, might prefer to wait for the Novavax booster.

Timing Is Key: What Works Best for You?

For some, the convenience of getting vaccinated sooner rather than later is a significant factor. Dr. Peter Chin-Hong, an infectious disease expert at the University of California, San Francisco, emphasizes the importance of “knowing thyself.” He suggests that if you’re someone who might forget to get vaccinated later in the year, it’s better to get the shot when it’s convenient for you, even if it’s earlier than the optimal window.

“I like to minimize my trips, so I plan to get my flu and Covid-19 shots at the same time,” Dr. Chin-Hong shares, echoing a sentiment shared by many busy adults.

Rethinking Covid-19 Vaccination Strategies

Dr. Peter Hotez, director of vaccine development at Texas Children’s Hospital, suggests that the current approach to Covid-19 vaccinations may need a reset. He points out that Covid-19 has caused significant waves every summer for the past few years, which raises the question of whether a once-a-year vaccination schedule is sufficient.

“The reality is that the mRNA vaccines are not as durable as we’d like,” Dr. Hotez says. He advocates for a twice-a-year vaccination strategy to better align with the virus’s seasonal patterns. This approach could offer more consistent protection, especially for those in high-risk groups.

However, implementing a twice-a-year vaccination strategy poses logistical challenges. “The question is whether vaccine manufacturers have the capacity to produce more than one batch of vaccines each year,” Dr. Hotez adds. As the pandemic evolves, so too must our strategies for keeping it under control.

Final Thoughts

As the U.S. prepares for the rollout of updated Covid-19 vaccines, it’s essential to consider personal factors when deciding the best time to get vaccinated. For those in high-risk categories, getting the shot sooner rather than later could be lifesaving. Younger, healthier individuals might choose to wait until closer to flu season to maximize their immunity during the winter months.

Ultimately, the most critical factor is ensuring that you receive the vaccine. Whether you get it now or wait a few weeks, staying up-to-date with Covid-19 vaccinations remains one of the most effective ways to protect yourself and others from severe illness.
