Vaccines against COVID-19, the seasonal flu and RSV are our best chance of preventing a winter surge, says researcher

As chilly and flu season ramps up, well being care specialists are as soon as once more on excessive alert for the possibility of a tripledemic, or a surge introduced on by the respiratory viruses that trigger COVID-19, the flu and respiratory syncytial virus, or RSV. The excellent news is that this 12 months, well being officers have extra instruments at their disposal to fight them.

Individuals ages six months and older are eligible to obtain the latest COVID-19 vaccine and the annual flu vaccine. As well as, this 12 months the Meals and Drug Administration authorised the first vaccine against RSV to be used in late being pregnant and adults 60 years of age and older.

RSV, COVID-19 and the flu are all contagious respiratory diseases which have similar symptoms, making it tough to differentiate between the three viral infections with out a lab check. Testing is the one option to know which virus is inflicting your signs. In actual fact, researchers are working to create one check that may detect COVID-19, RSV and the flu.

As a nursing professor with experience in public health promotion, I’m typically requested concerning the variations between these respiratory viruses. This 12 months, I’m fielding many questions on the timing of getting the brand new COVID-19 and RSV vaccines together with the flu shot, and whether or not they are often given collectively.

What to know concerning the signs

Signs of COVID-19, RSV and the flu can range from delicate—and even no noticeable signs in any respect—to extreme. Flu signs usually come on abruptly, whereas RSV and COVID-19 typically begin out delicate however can grow to be extreme over time. As well as, whereas a flu infection doesn’t usually have an effect on one’s capacity to style or odor, the loss of taste or smell generally is a frequent COVID-19 symptom.

All three infections may cause fevers and fatigue, whereas chills and physique aches are extra frequent with COVID-19 and the flu. Extra extreme signs of those infections embody issue respiratory and subsequent infections like pneumonia.

Timing the pictures

With the brand new RSV vaccine and updated COVID-19 vaccine now obtainable and flu season simply across the nook, a pure query is whether or not there’s an optimum schedule for the three pictures.

The reply to that query is, if you’re eligible, to get these vaccines as quickly as attainable. It is very important take into account that it takes roughly two weeks after vaccination in your physique to develop antibodies from each the COVID-19 vaccines and the flu vaccine.

The Centers for Disease Control and Prevention recommends that anybody who’s both unvaccinated or has beforehand acquired a COVID-19 vaccine earlier than Sept. 12, 2023, to get the up to date vaccine. This implies now’s the time to get the up to date COVID-19 vaccine that targets a beforehand dominant variant of the omicron household.

The unique COVID-19 vaccines and booster sequence have dramatically diminished the variety of COVID-19 infections, hospitalizations and death rates from the virus.

Whereas everybody six months of age and older is suggested to obtain each the COVID-19 and flu vaccines, sure populations have the next danger for extreme an infection, reminiscent of pregnant women, and ought to be further vigilant about getting vaccinated.

As well as, amongst these vaccinated towards COVID-19, signs throughout an an infection tend to be milder. Nonetheless, due partially to the shortly evolving nature of the virus, it has grow to be clear that immune safety from COVID-19 vaccination or an infection diminishes over time. Whereas research present that the first COVID-19 sequence maintains efficacy towards extreme illness and demise six months after vaccination, protection after vaccination decreases over time. Viruses, reminiscent of those who trigger COVID-19 and influenza, additionally repeatedly mutate and evolve.

The truth that COVID-19 vaccine immunity decreases over time and that viruses evolve are precisely why updated vaccines are so critical. With out a big uptake of up to date vaccines within the inhabitants, COVID-19 an infection charges may surge once more.

Timing can also be necessary with the flu vaccine. Flu circumstances usually start to rise in October and peak between December and February, but can last through May. Ideally, individuals ought to get vaccinated earlier than flu begins to unfold, making the month of October the ideal flu vaccination time.

However in case you miss that deadline, it’s completely higher to get vaccinated later within the season than in no way. Flu, COVID-19 and RSV vaccines can be found at your well being care supplier’s workplace, your native well being division and most retail pharmacies, though entry to the newly up to date COVID-19 vaccine is still limited in some areas of the country.

A tough respiratory virus season forward

Whereas infections and hospitalizations from COVID-19 declined dramatically in 2023, specialists are remaining vigilant towards the potential of new, more-infectious variants inflicting one other fall and winter surge. Adults 65 and older proceed to be the highest-risk group for extreme an infection.

Flu seasons are inherently difficult to predict. For the reason that emergence of the COVID-19 pandemic, flu cases have been lower than prior to the pandemic. Nonetheless, the 2022-2023 flu season nonetheless precipitated over 300,000 hospitalizations and as much as 98,000 flu-releated deaths, making vaccination an necessary prevention software.

To additional compound this, flu vaccine charges have been lower during the pandemic, suggesting that Individuals could also be out of the behavior of getting their annual flu shot.

Photographs could be given collectively

Many are additionally questioning whether or not they can or ought to get the up to date COVID-19 booster, the brand new RSV vaccine and the flu shot on the similar time. The excellent news is, the CDC clearly signifies that it is safe for each adults and kids who’re eligible for the up to date COVID-19 vaccine to get this vaccine concurrently with the annual flu shot.

A 2022 research discovered that frequent vaccine unwanted side effects, reminiscent of ache on the injection website, occurred at slightly higher rates when somebody acquired the flu vaccine and a COVID-19 vaccine on the similar time, versus receiving solely a COVID-19 booster. Nonetheless, these reactions, together with fatigue and headache, have been delicate and resolved inside a day or two. As well as, a latest research discovered that the immune response was the same when each vaccines got collectively in comparison with when given individually.

For the reason that RSV vaccine is new, there is no data yet on receiving all three vaccines at the same time. As an alternative, these on the highest danger of RSV an infection ought to get this vaccine as quickly as they’re ready.

Neighborhood issues too

Getting the COVID-19, RSV and flu vaccines is not nearly your individual well being—it is about household and group well being too. Communities with larger vaccination charges have fewer alternatives to unfold the virus.

Take note that many people cannot be vaccinated, as a result of they’ve weakened immune programs or are present process therapies. They rely on these round them for cover. Whereas one individual might expertise delicate signs in the event that they contract RSV, COVID-19 or the flu, they may unfold the virus to others who may grow to be severely ailing.

As a result of it is not possible to foretell how individuals will react in the event that they get sick, getting the flu and COVID-19 vaccines—and the RSV vaccine if you’re eligible—is the perfect prevention technique.
