Measles Cases Hit the Highest Number in 33 Years. Do You Need a Measles Vaccine Booster?

The number of measles cases in the US has risen to a record level. Learn how to protect yourself.

The measles outbreak that started in West Texas has now spread to nearly every US state and infected 1,288 people, according to NPR. That’s the largest number of measles cases since 1992.

With measles still infecting many people, you might be wondering about your own vaccination status and whether you are adequately protected from the potentially deadly disease.

According to the US Centers for Disease Control and Prevention, two doses of the MMR (measles, mumps and rubella) vaccine are 97% effective at preventing measles, while one dose is 93% effective. It is uncommon for someone who is fully vaccinated to develop measles, although the first breakthrough case of 2025 was recently detected in Colorado.

To learn more about measles symptoms and whether you need to get vaccinated again, we spoke with doctors for their expert insights.

What does measles look like in adults and children?

Measles is one of the world’s most contagious viruses with a number of symptoms to look out for — most notably a rash and fever, according to the CDC. The virus is spread through the air, and once infected, measles attacks your respiratory tract.

The Cleveland Clinic notes that there is no cure for measles, and measles just has to «run its course.» However, the best protection from it is a measles vaccine, which is typically given to babies in the form of the MMR (measles, mumps and rubella) vaccine.

Measles typically manifests at first as a «very specific rash that starts from the face and spreads down your body,» says Dr. Yoshua Quinones, board-certified internist with Medical Offices of Manhattan. Other common side symptoms to watch out for include «high fever, cough, runny nose and watery or red eyes.»

Quinones adds, «Occasionally, you may see small white spots inside your mouth. These are named Koplik spots.»

While measles can and will make anyone sick, the CDC reports that it is especially dangerous for children younger than 5. This is because children have undeveloped immune systems and are at a higher risk of illnesses, making them vulnerable — especially if they haven’t been vaccinated.

How does the measles vaccine work?

The measles vaccine protects people from getting measles. It’s known as the MMR, because it’s combined with the vaccines for mumps (a contagious viral infection that affects the salivary glands) and rubella (another contagious viral infection that typically starts with a red facial rash). You may also see the MMRV, which includes a vaccine for varicella or chickenpox.

«The vaccine is a live virus that is introducing a very weak form of measles so your body can practice fighting it off,» says Quinones. «This will prepare your immune system to fight against measles if you’re exposed.»

One dose is typically given during infancy, with a second dose to follow a few years later. The vaccination is especially important for children because their immune systems are weaker. This is why both doses are recommended before they are in school, where they will be exposed to more children (and more germs).

Who should get the measles vaccine?

Measles vaccines are typically given to all children. The first vaccine is usually given between 12 and 15 months of age and the second one is given between 4 and 6 years of age before children go to school, according to the CDC. The ages can vary, though, as long as the doses are properly spaced out.

Vaccines can also be given to adults who haven’t previously been vaccinated or are not immune, although they typically only get one dose. Dr. Omar Al-Heeti, an assistant professor of medicine at Southern Illinois University who practices internal medicine with a specialty in infectious diseases, and one of CNET’s medical reviewers, adds that adults born during or after 1957 should have at least one dose of the MMR vaccine or presumptive evidence of immunity.

According to Al-Heeti, presumptive evidence of immunity is defined as one of the following:

Written documentation of vaccination with two doses of live measles or MMR vaccine administered at least 28 days apart
Laboratory evidence of immunity (positive serum IgG)
Laboratory confirmation of disease
Birth before 1957 (According to the CDC, although birth before 1957 is considered presumptive evidence of immunity, for unvaccinated health-care personnel (HCP) born before 1957 who lack laboratory evidence of measles immunity or laboratory confirmation of disease, health-care facilities should consider vaccinating personnel with two doses of MMR vaccine at the appropriate interval.)

The CDC recommends that adults who work in the health-care field, attend college or university, or travel internationally get two doses separated by at least 28 days, as they are deemed to be at higher risk for acquiring the infection.

Should you get a measles booster if you were already vaccinated?

Despite the ongoing measles outbreak, there is likely no need to get an additional measles vaccine — unless you aren’t fully vaccinated already or have proven immunity (previous infection/exposure).

«If someone is fully vaccinated against measles (two doses) and has not had a major immunocompromising condition occur (e.g., organ transplant), their immunity should be sufficient with no need for further dosages,» says Amesh A. Adalja, an infectious disease specialist and a senior scholar at Johns Hopkins Center for Health Security.

The first measles vaccine dose is usually given to infants and toddlers, with the second dose given during the childhood years. If the second dose was never given, someone could be at higher risk for measles and would, in fact, benefit from another measles vaccine now.

A recent report noted that some people originally vaccinated in the 1970s and 1980s may need a new vaccine because the original wore off. This could be because they were only given one dose and the vaccine has evolved since then, and it was potentially not caught in some people’s medical records.

«If you already have your full series, you don’t need an additional dose; however, I highly recommend checking your titers if you have any doubts,» Quinones says. «An extra shot will never add extra protection because you’re very well protected.» According to Mount Sinai, an antibody titer test measures the level of antibodies in a blood sample to see which vaccines you may need.

Ask your primary care doctor to check your vaccination status to see if your MMR vaccination is up to date and to see if you may need a booster. If it’s current and you are not immunocompromised, you likely do not need an extra shot. The CDC also notes that adults who have received a single dose and have «presumptive evidence of immunity» — documentation of vaccination or immunity — don’t need to get another one.

Who shouldn’t get the measles vaccine?

While the measles vaccine is generally considered safe, some groups of people are advised to avoid it. Quinones recommends that pregnant people not get the vaccine. It is also advised to wait at least a month after giving birth before getting a vaccine.

The CDC also recommends that people who had an allergic reaction to the first MMR vaccine hold off on getting the second dose. In addition, people with any «severe, life-threatening» allergies should consult their doctor before getting vaccinated because it may not be safe.

Those with weakened immune systems should also consult their doctor about getting the vaccine, especially if it is because of disease or medical treatment. If immunodeficiencies run in the family, this could also cause an issue with the shots.

The vaccines can also potentially react with recent blood transfusions so it’s not recommended to get the MMR or MMRV within at least three months of receiving blood from someone. You should also not get the vaccine if you currently have tuberculosis or bruise or bleed easily, according to the CDC.

The MMR doses need to be spaced out by at least 28 days, and you should also not get one of these doses if you’ve had another vaccine within 28 days as well. It’s also important to let your health-care provider know if you’ve been sick recently — with any sort of illness — so they can advise if it’s still safe to vaccinate. If you’re a parent bringing in a child for vaccination, also advise the doctor if the baby has been sick or shown any previous symptoms of concern.

Or if you were born before 1957, you may already have immunity.

Is the measles vaccine safe?

According to medical experts and the CDC, the measles vaccine is safe and effective. Some slight side effects may occur after getting the shot, but they are generally minor and go away quickly.

«The measles vaccine may cause fever, chills and muscle aches/pains in the days after injection,» Adalja said.

Quinones also points out that it’s possible to feel sore at the injection site following the shot.

Beyond this, the CDC reports that it’s possible to see some swelling in the cheeks or neck and in rare cases, a bleeding disorder that will eventually resolve itself. In more severe cases, it’s possible to have an allergic reaction to the vaccine, which would require calling 911 right away, especially if there’s trouble breathing, intense swelling or dizziness.

The CDC also reports a small link between the MMR vaccine and febrile seizures, but it is rare and not linked to long-term effects. However, the organization recommends that parents vaccinate their children early to lessen the chances of this occurring.

The CDC also calls out the notion that vaccines were once linked to autism and shuts down any possibility that the two are related to each other, citing experts and research. The CDC states, «There is no link between autism and vaccines that contain thimerosal as a preservative.»

Does health insurance cover the measles vaccine?

Typically, all Health Insurance Marketplace plans and private insurance plans offer the MMR vaccine (as well as other common vaccines) without charging a copayment or coinsurance, as long as you’re with an in-network provider, according to the CDC. Medicare likely also covers the vaccine, whether on Part B or Part D, and so does Medicaid, but it’s always best to double-check with your medical facility and with Medicare or Medicaid to be certain.

Military benefits can also vary depending on coverage, but the MMR vaccine will most likely be covered, as the CDC recommends it be covered across the board.

The bottom line

Despite the outbreak that is currently happening in the United States, people do not need to get another measles vaccine if they’ve already sufficiently been vaccinated. However, doctors suggest checking with your health-care provider if you have any concerns about the efficacy of the vaccinations you received and to find out if a booster shot could be necessary, especially if there is an outbreak in your community. If so, experts make it clear that the measles vaccine is safe and will protect you from the virus.

WeTransfer Backtracks on AI File Training After Backlash: What You Need to Know

The company has updated the changes to its policies after some users objected to new terms.

WeTransfer, the service that allows users to send large files to others, is explaining itself to clients and updating its terms of service after a backlash related to training AI models.

The company published a blog post, «WeTransfer Terms of Service — What’s Really Changing,» that details more updates the company made to its policies, after users noticed that recent changes seemed to suggest WeTransfer was training AI models on the files users are transferring.

In the blog post, the company says: «First things first. Your content is always your content.»

The post goes on to say, «We don’t use machine learning or any form of AI to process content shared via WeTransfer.» WeTransfer explains that its use of AI would be to improve content moderation and enhance its ability to prevent the distribution of harmful content across its platform.

The company adds that those AI tools aren’t being used and haven’t been built yet. «To avoid confusion,» it says, «we’ve removed this reference.»

A representative for WeTransfer did not immediately return an email seeking further comment.

The backlash over the terms prompted users such as political correspondent Ava Santina to write on X, «Time to stop using WeTransfer who from 8th August have decided they’ll own anything you transfer to power AI.»

What this means for users

Anxieties are high about what information users share or store in services such as social media accounts is accessed by companies to train AI models. WeTransfer may be used for highly sensitive file transfers, raising fears that private information might be accessed by AI. According to the company, this isn’t the case.

To further explain, the company said in its post:

«YES — Your content is always your content. In fact, section 6.2 of our Terms of Service clearly states that you ‘own and retain all right, title, and interest, including all intellectual property rights, in and to the Content’.»
«YES — You’re granting us permission to ensure we can run and improve the WeTransfer service properly.»
«YES — Our terms are compliant with applicable privacy laws, including the GDPR.»
«NO — We are not using your content to train AI models.»
«NO — We do not sell your content to third parties.»

When the Terms of Service change

While eagle-eyed experts understood the potential implications of what WeTransfer’s new terms could mean for people using the service, it’s unlikely that most people would be able to spot such changes.

«Expecting users to fully understand Terms of Service is unrealistic. These documents are often too complex to navigate,» says Haibing Lu, associate professor at the Leavey School of Business at Santa Clara University.

Lu told CNET that companies would do well to clearly highlight any changes they make to AI-related terms and explain them clearly to give people a real choice. «That’s what true transparency looks like,» Lu says. «Companies are increasingly risking backlash when they update Terms of Service to include AI, especially when users’ data is involved.»

Companies including Adobe, Slack and Zoom have had similar issues with terms changes related to AI, but it’s not just AI that’s the problem, Lu says — rather, it’s the lack of transparent communication.

In the case of WeTransfer, Lu says the company’s response, including revising the terms and blogging about them, «was a smart move and helped rebuild trust. It showed they were listening and willing to act fast.»

WeTransfer could include more understandable language in its terms, or communicate the changes better or sooner, Lu says, adding: «Transparency shouldn’t start after a backlash.»

It’s Easy to Add Your Driver’s License to Your iPhone or Apple Watch if You Live in These 9 States

Digitize your state ID to cruise through the airport security line.

While some phone makers are working overtime to squeeze AI into every single feature, Apple is taking a more fundamental step to simplify travel by digitizing your driver’s license. You can now add your state ID to your iPhone or Apple Watch using Apple Wallet, allowing you to breeze through airport security checkpoints card-free.

Living in California, I was interested in giving it a shot to see if it was as easy as it looks to be. And it is, as long as you have the right iPhone and OS version. Older iPhones, depending on the state you live in, may create some problems. Apple says digitized driver’s licenses will work on iPhone 8 and later, but it’s a little more complicated than that.

Right now, digital IDs are primarily used to go through TSA checkpoints in certain airports when flying domestically, but that’ll likely change in the future. Want to use your digital ID at your favorite bar or nightclub? We’re not there yet.

Below, I describe my experience, the hiccups I encountered on the way and things that you should know if you plan on adding your driver’s license to Apple Wallet. I’ll also break down how you can add your ID to your iPhone, step by step.

For more, don’t miss these low-key iOS 26 features we’re excited for.

These states support digital IDs on iPhones right now

Only a handful of states support digital IDs in Apple Wallet. One key factor is how each state implements its Mobile Driver’s License system. For instance, Louisiana, New York, Utah and Virginia all support mobile driver’s licenses but require separate apps for digital IDs.

States and regions that support digital IDs in Apple Wallet:

Arizona
California
Colorado
Georgia
Hawaii
Iowa
Maryland
New Mexico
Ohio
Puerto Rico

Some states originally announced to support Apple’s digital ID haven’t quite gotten there yet.

The number of states supported in Apple Wallet is about half of what the TSA currently allows. Collectively, it accepts digital IDs across Apple Wallet, Google Wallet, Samsung Wallet and state-based mobile apps in 15 states.

What are the iPhone requirements to add your driver’s license to Apple Wallet?

Where you live is just the start. You also have to have the right iPhone model and the right software setup.

Here are the minimum requirements that Apple lists:

An iPhone 8 or later with the latest version of iOS
Have Face or Touch ID enabled on your device
Have two-factor authentication enabled on your Apple account
A license or ID from a participating state or territory
Your device’s region set to the United States

I’ll have more to say in a bit about that iPhone 8 and iOS requirement and a catch I ran into.

My experience adding my ID to my iPhone was easy

For testing purposes, I used the iPhone 16E.

The process of adding the ID was simple. I scanned the front and the back of my ID and the next step was to verify my identity. This wasn’t nearly as nerve-wracking as I thought it would be. Instead, it took a live photo of my face for 2.5 seconds.

After that, more verification was required. This came in a series of different photos, with prompts directing me to close my eyes, open my mouth, smile and tip my head down. This verification process took about three minutes. (Or longer in my case, as I got distracted writing notes about the process and then found I had to restart the whole process.)

Then, after I submitted those photos, there was another verification step, presumably with the photos relayed to the California DMV. A screen message told me that I would receive a notification when there was an update. I expected this to take a long time, but not even 10 minutes later, a notification telling me that my ID was ready to use popped up. That was easy.

What about older iPhones?

So, not every phone you think might work will actually do so. The first time I tested adding my ID, I was using an iPhone 8 Plus. But when I arrived at the setup page within Apple Wallet, I was given eight states to choose from, and California wasn’t one of them.

That surprised me. I’d found a helpful Apple support article that explained the requirements for adding a driver’s license or state-issued ID to Apple Wallet and it seemed like I shouldn’t have any trouble.

At first, I thought the roadblock was that I hadn’t set up Touch ID yet. But no, California was still not on my list of eight states. (Equally confusing, a colleague of mine also tried this with an iPhone 8 and Apple Wallet only listed four states.)

I went back to the Apple support article and looked for fine print, and sure enough, there it was. I’d ignored the asterisk in the requirements, because California has had its Mobile Driver’s License program set up for some time now.

The fine print at the very bottom of the page states, «For California, ID in Apple Wallet requires iPhone XS or later with iOS 17.5 or later.» (For Puerto Rico, if you want to add your driver’s license or ID to Apple Wallet, you’ll need to have an iPhone XS or later with iOS 18.1.)

So if you’re holding onto an iPhone 8 or iPhone X and live in California, you won’t be able to add your driver’s license to your iPhone because of the lack of software support. iOS 16 is the last supported version of the operating system for iPhone 8 and X models.

How to add your ID or driver’s license to Apple Wallet

If you live in a state that supports digital IDs for Apple Wallet, it’s easy to add one. After it’s added, you’ll need to verify your identity, which can take a little longer but it’s still a straightforward process.

Open Apple Wallet.
Tap the Add button.
Tap Driver’s License or ID and select your location.
If applicable, choose whether you want to add your ID to your iPhone only or your iPhone and your Apple Watch.
Follow the steps to scan your license or ID.

(Make sure you scan your ID in a well-lit environment and that the image is in focus.)

Once it’s scanned, you’ll be prompted to confirm your identity with a selfie photo. According to Apple, you may be asked to complete a number of facial or head movements for identification purposes.

To ensure an easier verification process, Apple suggests that you:

Stand in front of a plain background with neutral, light paint.
Be in a well-lit area, ideally indoors.
Take off sunglasses, masks, hats or other accessories that could block your face.
Hold your iPhone steady.

When you’re finished, submit your information by confirming with Touch or Face ID. Your biometrics will be bound to the ID, so only you can use it.

How to transfer your digital ID to another iPhone

If you upgrade your iPhone, you’ll need to transfer your ID or driver’s license to it.

During initial setup, tap Wallet.
Select your ID.
Follow the steps.
Tap to confirm you want to move your driver’s license or ID to the new device.

So, now what?

Your digital ID isn’t just a photo of your ID that you can pull up within Apple Wallet. In fact, you don’t even see a full image of your physical ID. In order to actually view your information from your digital ID, you’ll need to tap on your ID «card» in Apple Wallet, tap the «i» at the top-right of the screen, and then tap State ID info or Card Information (the wording may be different depending on what version of iOS your iPhone is running). From there, it will show your ID photo as well as essential pieces of information from your physical ID.

TSA checkpoints that support digital IDs require a dedicated scanner, so the process may not necessarily feel like it’s faster than showing your physical ID to the agent.

Here’s a video of the process via the Maryland Department of Transportation:

The idea of a digital ID is pretty convenient but overall, it probably won’t save you a meaningful amount of time. Couple that fact with its incredibly limited use cases right now and the fact that merchant or event adoption will require investment in proper hardware and it’s pretty easy to see just how far off we are from ditching physical IDs.

Selling or trading in your iPhone? Do this first.

When you move on from a phone that has your ID on it, you’ll want to do the same thing you do with other sensitive info like credit or debit cards and passwords: Remove it.

So before you wipe your iPhone to sell or trade it in, you should manually remove your ID first. Here’s how to do it.

Go to Apple Wallet and tap your ID in the list
Tap the «i» button at the top right of the screen
Tap Remove State ID (or Driver’s License)
Read the warning that pops up and tap Remove

Digital passports are coming to Apple Wallet with iOS 26

While states are taking time to implement digital ID systems, Apple announced a feature coming in iOS 26 this year: You can add a digital passport to Apple Wallet.

When that feature is available, iPhone users will be able to scan their passports to create a digital version for identity verification during domestic travel. You won’t be able to use it for international travel and it’s not a full replacement for a physical passport (so keep your physical one on you) but it should work at the 250-plus supported TSA checkpoints.

During its WWDC keynote in June, Apple said that the digital ID made from your passport can also be used «in apps and in person» but it didn’t give any specifics.

This is essentially what can be done on Android through Google Wallet.

Verify with Wallet ID verification could make ordering alcohol easier

Also headed to iPhones this fall is an easier way for you to prove your age using your digital ID. Say you want to have a bottle of wine sent to your place via Uber Eats. Typically, when the driver arrives, you’ll need to present your ID and have it scanned to complete the transaction but with the new Verify with Wallet, your stored digital ID will be used to verify your age. (I do wonder if things might get more complicated when the delivery arrives if you’re not the one receiving it.)

Verify with Wallet will be supported by Chime, Turo, Uber Eats and U.S. Bank.
