In an ideal scenario for this upcoming winter season, the United States would completely transform its approach to respiratory illnesses. Before the pandemic, fall was primarily known as the time for flu shots, and not much else. However, now there are vaccines readily available that can effectively combat three common winter viruses at once: the flu, COVID-19, and respiratory syncytial virus (RSV) for a particular subset of the population. If everyone who is eligible gets vaccinated, it would have a tremendous impact in terms of reducing hospitalizations, and most cases of respiratory illnesses would be no worse than a common cold. Ofer Levy, the director of the Precision Vaccines Program at Boston Children’s Hospital, stated that this could potentially save tens of thousands of lives in the United States alone.
The idea behind this plan is simple: there are few public health priorities that are more urgent than ensuring that those who need these three lifesaving vaccines the most receive them before the winter season brings about an increase in viral infections. However, the logistics of achieving this goal are not as straightforward. The key to reaching as many people as possible is to make the process of getting vaccinated extremely easy. Chelsea Shover, an epidemiologist at UCLA, emphasized the importance of simplifying the vaccination process. Unfortunately, the current system for administering these shots in the fall is not designed to make it easy for people to get vaccinated.
Convenience is just one of the factors that contributes to the low vaccine uptake. Overcoming fear, mistrust, and misinformation is crucial, but even after addressing these barriers, there are still challenges such as insurance coverage, scheduling appointments, and finding the time to get vaccinated. This is particularly true for adults who do not regularly visit their doctors for check-ups and whose workplaces do not have vaccine requirements like schools do. As a result, getting vaccinated has become a burdensome task.
One potential solution to streamline the process is to bundle the flu, COVID-19, and RSV vaccines into a single visit. This would reduce the number of appointments individuals need to make and ultimately make it easier for them to receive multiple shots. Tochi Iroku-Malize, the president of the American Academy of Family Physicians, highlighted the importance of minimizing the number of visits patients have to make and supported the idea of a three-in-one shot. However, this option does not currently exist, although it is being explored through trials. Alternatively, administering up to three separate shots at once is also challenging. Flu vaccines have already been made available by pharmacies, while RSV vaccines are only offered to certain groups. COVID-19 vaccines are expected to be available to all Americans in the fall, but their release date is still a few months away. Timing the shots correctly is crucial to ensure optimal protection and to avoid the virus potentially outpacing the vaccine. There are also concerns about potential side effects and how co-administering vaccines might impact their efficacy. Nevertheless, Levy argues that the benefits outweigh these concerns and that it is better to receive a slightly less effective shot earlier than not receiving one at all.
Another issue is raising awareness about the eligibility for these shots. Family medicine physicians have already been receiving inquiries from confused patients about the RSV vaccines. For example, some parents wrongly believe that the RSV vaccines are meant for infants, when in fact, they are given to pregnant individuals to protect babies temporarily through the transfer of antibodies. There is still uncertainty regarding how often older adults should receive the RSV vaccine. Regulators have not finalized their recommendations, which adds to the confusion. Jacinda Abdul-Mutakabbir, an infectious disease pharmacist at UC San Diego, expressed the difficulty of telling patients that there are still unanswered questions. The messaging surrounding the RSV vaccine is also complicated due to safety concerns, but experts still recommend it despite some rare but serious side effects reported during clinical trials. Some health insurance companies have used the CDC’s conservative stance as an excuse not to cover the cost of the vaccine, leaving patients to pay out of pocket.
Public perception and awareness of these viruses are also significant factors. RSV is not as well-known as the flu, and people tend to underestimate its severity. This could pose challenges for the uptake of the RSV vaccine. Similarly, people may disregard getting vaccinated against the flu and COVID-19 if they perceive these illnesses to be less severe. Currently, only 28% of American adults are fully vaccinated against COVID-19. Even vaccines for diseases like shingles, which can be extremely painful, have low uptake rates among individuals aged 60 and above. To establish fall as a season of seeking immunity through vaccination, shots need to become a regular habit. Mandates and financial incentives can encourage vaccination, but smaller nudges and changes in messaging can also make a significant difference. For example, using terms like “due” for a vaccine rather than presenting it as an optional choice can increase acceptance. Text-message reminders that create a sense of ownership also prove effective. Looking to dentists who employ persistent reminders through phone calls and postcards could serve as inspiration for vaccine providers.
Streamlining vaccine delivery is another crucial step. Government funding can make shots more accessible in rural areas, ensure coverage for the uninsured, and help local health departments offer vaccines in unconventional locations like churches and salons. Increasing vaccination rates in schools and workplaces can also be beneficial. Additionally, improving recordkeeping systems can help track individuals’ vaccination history over their lifetime. Kimberly Martin, a behavioral scientist at Yale, is researching ways to revamp medical training to enhance vaccination efforts.
In conclusion, the United States needs a comprehensive approach to respiratory diseases, including concerted efforts to ensure widespread vaccination against the flu, COVID-19, and RSV. This requires overcoming logistical challenges, improving public awareness, streamlining vaccine delivery, and implementing effective messaging. By addressing these factors, fall can truly become a season of proactive immunity-seeking through vaccination.
