Lately, nevertheless, COVID-19 has not solely stolen the general public well being highlight but additionally eclipsed the event of the primary RSV vaccine.
“[RSV] can be very risky, but people are not as aware of it as a virus in itself,” Dr. Sujata Ambardar, an infectious illness specialist at Inova Fairfax Hospital in Falls Church, Va., tells Fortune. “They think of COVID, flu, and other viruses.”
Although Ambardar believes RSV consciousness is on the rise, she says the prevailing lack of affected person training—coupled with COVID- and flu-induced vaccine fatigue—might account for minimal curiosity within the trio of latest RSV vaccines for individuals 60 and older.
As just lately as 18 months in the past, no RSV vaccine existed. The Meals and Drug Administration (FDA) authorized the nation’s first RSV vaccine, GSK’s Arexvy, on Could 3, 2023. In a assertion that day, Dr. Peter Marks, director of the FDA’s Heart for Biologics Analysis and Analysis, deemed the event “an important public health achievement to prevent a disease which can be life-threatening.”
The FDA authorized Pfizer’s Abrysvo on Could 31, 2023, and precisely a 12 months later did the identical for Moderna’s mResvia. But as of spring 2024—simply weeks earlier than mResvia’s approval—lower than 25% of eligible adults 60 and older had gotten an RSV vaccine, in response to the Facilities for Illness Management and Prevention (CDC).
1 in 5 older adults plan to get RSV vaccine
Vaccine uptake might not be a lot better in the course of the 2024–25 respiratory virus season. Fewer than two in 5 (38%) eligible recipients plan to get an RSV vaccine, in response to a survey performed in August by the Nationwide Basis for Infectious Ailments (NFID), together with 21% who “definitely will” and 17% who “probably will.” Practically half (44%) stated they’re not sure (18%) or don’t plan to (26%) get immunized.
Those that stated they received’t get vaccinated cited the next amongst their reasoning:
- Considerations about uncomfortable side effects from the vaccine: 45%
- Considerations about getting sick from the vaccine: 38%
- Mistrust of vaccines normally: 38%
- Physician has not really helpful it: 24%
The RSV vaccines’ newness additionally breeds mistrust, says NFID medical director Dr. Robert Hopkins Jr.
“Part of it is we’re seeing a general decline in confidence in vaccines, a general decline in confidence in a lot of things related to health care,” Hopkins tells Fortune. “That’s a lot of our barrier. I think it’s also challenging for a lot of people in the public to say, ‘Well, wait a minute, why haven’t I heard about this virus before if it’s that important?’”
Alternatively, survey respondents who stated they’ll get vaccinated or are not sure thought of these elements:
- To guard themself: 72%
- To keep away from extreme issues, together with hospitalization and demise: 61%
- Physician suggestion: 59%
- To guard their household: 58%

Nonetheless, it’s at all times RSV season in some hotter climates—reminiscent of southeast Florida—and you’ll catch the virus year-round regardless of the place you reside.
What are RSV signs?
Most individuals with RSV exhibit the next delicate, cold-like signs, the CDC says, which manifest 4 to 6 days after an infection:

However youngsters beneath 5 and adults 60 and older are at excessive danger of extreme an infection leading to hospitalization. The latter are additionally in peril of demise.
Older adults with RSV can develop pneumonia, and people with issues together with bronchial asthma, coronary heart failure, and power obstructive pulmonary illness (COPD) might expertise worsening situations, the CDC says. Yearly within the U.S., about 6,000 to 10,000 individuals 65 and older die from RSV. In a research printed final 12 months within the Journal of Scientific Virology whose topics had been a mean 75 years outdated, RSV infections had been extra extreme than flu infections.
Whereas RSV is rampant amongst and infrequently critical for younger youngsters, it’s vital that the general public understands the virus extends past little ones, Ambardar says. Actually, youngsters will be the supply of an infection for an much more weak group.
“Especially for people who are over 75, [RSV] can require hospitalization and can be quite bad—and we don’t think about it that way, because we’re associating it with only kids,” she tells Fortune. “You have grandparents visiting their grandkids, and the grandkids may be the ones harboring the virus. The grandfather who’s 75, 80 may get sick and may not even know it if he goes to the ER because he’s thinking: flu.”
Who ought to get an RSV vaccine?
All three RSV vaccines are FDA-approved for adults 60 and older, however over the summer time the CDC up to date its immunization suggestions:
- Everybody ages 75 and older obtain the RSV vaccine
- Folks ages 60 to 74 who’re at elevated danger of extreme RSV, that means they’ve sure power medical situations, reminiscent of lung or coronary heart illness, or they dwell in nursing properties, obtain the RSV vaccine
Although the CDC hasn’t formally really helpful an RSV vaccine for the overall inhabitants youthful than 60, the FDA in June authorized Arexvy for adults 50 to 59 who’re at elevated danger of RSV decrease respiratory tract illness. When unsure, focus on along with your physician which RSV vaccine could also be best for you.
No vaccine is authorized for infants, nevertheless, expectant mother and father can present their unborn youngsters passive immunity by getting the Abrysvo shot late in being pregnant. Infants whose birthing father or mother was unvaccinated could also be eligible for a monoclonal antibody remedy known as nirsevimab.
Right here’s a breakdown of who’s eligible for which RSV vaccines:
- Moderna mRNA vaccine (mResvia)
- Indicated for adults 60+
- 1 dose wanted
- Advisable late summer time by means of early fall
- Pfizer protein vaccine (Abrysvo)
- Indicated for
- Adults 60+ (really helpful late summer time by means of early fall)

- Indicated for
Flu and now COVID vaccines are reformulated yearly as a result of their corresponding viruses mutate comparatively rapidly. RSV reveals a slower evolution, Hopkins says, that means that a minimum of in the interim, a single dose of the RSV vaccine is all it’s worthwhile to stave off extreme an infection.
“We now have three vaccines that are available for older adults,” Hopkins says, “and so my hope is that as we get more data, we may be able to expand use beyond the current groups for whom they’re recommended and provide protection for more of our population.”
