Why Getting Your 2024 COVID and Flu Shots Before Halloween Is a Good Idea

If you haven’t yet sought out your updated COVID-19 vaccine — or your flu shot — now might be a good time.

That’s because, after a lengthy COVID-19 surge this summer that lasted twice as long as 2023’s summer swell, the Bay Area is now about to enter the winter respiratory virus season.

In August, the updated 2024 COVID-19 vaccine was made available to everyone age 6 months and over, with shots from manufacturers Pfizer, Moderna and most recently, Novavax. These COVID-19 vaccines are now provided as annual fall vaccines, alongside the yearly flu shot, updated to target the latest strains and timed in order to offer maximum protection against the predicted winter surge of these viruses.

All of which means if you haven’t gotten either your COVID-19 or flu shot yet at this stage in the fall, seeking them out in the next few weeks is a good idea. Keep reading for what you need to know about fall vaccines, including the best time to get them, what to do if you got COVID-19 this summer and more.

When is the best time to get my COVID and flu shot?

The recommendations medical professionals make about when to get a COVID-19 or flu shot are based on:

• The fact that it takes about two weeks after you get vaccinated for antibodies to develop and provide protection against the virus
• When levels of the virus are predicted to rise that year

Getting your COVID shot

Last year, the Bay Area’s fall and winter COVID-19 surge began in late October, according to Stanford University’s WastewaterSCAN team, which monitors levels of the virus in local sewage. And when it comes to the timing of your COVID-19 shot, you want to aim for what UCSF infectious disease expert Dr. Peter Chin-Hong called “the Goldilocks moment.”

“You don’t want to get it too soon because your antibodies might wane just when you need it the most,” Chin-Hong said. “And you don’t want to get it too late because you want to prevent infection. So generally, by Halloween or mid to late October is when most people say the right time is.”

The reason for this, explained Chin-Hong, is to ensure you get your full immunity ahead of the busy holiday season, from trick-or-treating at Halloween to holiday travel, Thanksgiving and beyond.

With your vaccine, “you not only get protection against serious disease, hospitalization and death, but you get a little bit of a buffer against infection itself,” Chin-Hong said. “So that if you want to have peace of mind while doing all of these things, it’s probably a good idea to peak your antibodies just when people are getting together again.”

Getting your flu shot

The Centers for Disease Control and Prevention estimates that last year’s flu season caused between 17,000 and 100,000 deaths and up to 900,000 hospitalizations. Typically, flu season starts in November and peaks around January or February, Chin-Hong said.

The CDC recommends that everyone 6 months and older get an annual flu vaccine “ideally by the end of October.” Chin-Hong told KQED that his “optimal sweet point” for getting this shot is “sometime before Halloween” — but that if you see flu cases start to rise earlier, you should hustle to seek out your flu shot even sooner.

Can I get my COVID and my flu shot at the same time?

Yes — it’s totally fine and safe to get your flu shot at the same time as your new COVID-19 vaccine, and you’ll find many pharmacies offer appointments where you can get multiple vaccines at the same time.

A caveat: if you’re trying to schedule vaccinations for a child, the CDC advised in 2023 that you first talk to your pediatrician about the best schedule for the COVID-19 and flu vaccines (and now the RSV — respiratory syncytial virus — preventive treatment, too).

I got COVID over the summer. Do I still need a COVID shot?

Yes, Chin-Hong said — although make sure you’re not getting a shot too soon after having COVID-19.

That’s because “after getting infected with COVID, in general, you have a force field for around three months,” Chin-Hong said, meaning your infection will give you a good level of immunity against getting COVID-19 again during that period.

That said, this immunity will wane, Chin-Hong said, so having “a little bit of a buffer” is something to consider. This means getting your COVID-19 shot even after two months “won’t be a bad idea if it coincides with the time when we expect COVID to come back.”

Where can I get my COVID and flu shot?

For full information on how to find an updated 2024 COVID-19 shot, read our guide. If you have health insurance, the cost of your COVID-19 vaccine should be fully covered.

To learn more about where to find a flu shot with or without insurance, read our 2023 guide to locations offering flu vaccination around the Bay Area.

Remember that many locations — including pharmacies — will offer appointments where you can get both vaccines at the same time.

What about RSV? Should I get a vaccine for that?

The CDC said that while RSV “does not usually cause severe illness in healthy adults and children,” older adults and infants younger than six months of age are especially at risk of becoming “very sick and may need to be hospitalized.”

The vaccine against RSV is accordingly recommended by the CDC for infants, young children and adults ages 60 and older, as well as for pregnant people.

The virus spreads in the fall and winter like other respiratory viruses and “usually peaks in December and January,” according to the agency, which recommends that vaccination against RSV “will have the most benefit if administered in late summer or early fall [August through October], just before the RSV season.”

Speak to your health care provider about getting the RSV vaccine, when might be the best time for you and whether to get it alongside other vaccines. And as ever, if you’re trying to schedule your kid’s vaccinations, the CDC advises that you first talk to your pediatrician about the best schedule for the COVID-19, flu and RSV vaccines.
